    Abstract The 12 interspecific hybridization combinations in Fragaria were performed to select promising individuals with improved cold resistance. The interspecific hybrids were obtained from the six combinations of Chandler (8 x ) × F. viridis (2 x ), Toyonoka (8 x ) × F. viridis (2 x ), Chandler (8 x ) × F. orientalis (♂) (4 x ), YH15-10 (12 x ) × F. orientalis (♂) (4 x ), AY175 (10 x ) × F. moschata (♂) (6 x ) and F. moschata (♀) (6 x ) × YH15-10 (12 x ), while failed in their reciprocal crosses. The chromosome number, morphological character and cold resistance of the interspecific hybrids and their parents were investigated. Five ploidy hybrids, including pentaploid (2 n = 5 x = 35), hexaploid (2 n = 6 x = 42), octaploid (2 n = 8 x = 56), enneaploid (2 n = 9 x = 63) and decaploid (2 n = 10 x = 70) were obtained. Only one ploidy hybrid was observed in each combination, except for the combination of YH15-10 × F. orientalis (♂), in which two ploidy hybrids (8 x and 10 x ) were obtained. The identified chromosome number indicated that all of the observed individuals were true hybrids. Compared with the parents, most of the hybrids showed intermediate phenotype. The strong aromatic individuals were obtained, although most hybrids were sterile. The fertility of the hybrids from YH15-10 × F. orientalis (♂) was better than that of the other five combinations. Majority of the hybrids exhibited stronger cold resistance than lower cold resistant parent. For instance, 80.00% and 83.33% hybrids respectively from Toyonoka × F. viridis and Chandler × F. orientalis (♂) revealed superior cold resistance than the lower cold resistant parents ‘Toyonoka’ and ‘Chandler’. The five ploidy interspecific hybrids (5 x , 6 x , 8 x , 9 x and 10 x ) with strong cold resistance obtained in this study were valuable resources for strawberry cultivar improvement. Highlights The 12 interspecific hybridization combinations were performed in strawberry. Five ploidy strawberry hybrids, including 5 x , 6 x , 8 x , 9 x and 10 x were obtained from six combinations. Two ploidy hybrids (8 x and 10 x ) were obtained from YH15-10 (12 x ) × F. orientalis (♂) (4 x ) and their origins were speculated. The cold resistant strawberry hybrids with strong aroma were obtained.

    Abstract The objective of this study was to evaluate the development and the quality of leaves from several S. rebaudiana Bertoni strains cultivated under temperate climate conditions in the tunnel and in the open field in the relation to the photosynthetic activity. Investigated stevia strains differed significantly in terms of whole plant and leaf morphology, photosynthetic efficiency as well as in the content of steviol glycosides, and antioxidant capacity, independently of cultivation place. On the basis of several chlorophyll a fluorescence parameters analysis it was stated that plants of all examined strains, did not exhibit photosynthesis inhibition. The studies of the relationship between photosynthetic activity and the level of secondary metabolites indicated that the highest content of steviol glycosides and phenolic compounds had plants showing also the highest value of the energy fraction photochemically converted in PS II ( YII ), while the highest ratio of rebaudioside A to stevioside content corresponded with low amount of energy dissipated as a heat ( YNPQ ). This results might indicate that steviol glycosides play a role in the better adaptation to environmental conditions. Karyology and cytometric studies revealed that all investigated stevia strains were diploids without significant differences in 2C DNA amount. Therefore, observed diversity in the content of steviol glycosides and phenolic compounds between investigated S. rebaudiana strains was not the effect of polyploidization but probably resulted from the differences in the metabolic activity of the examined plants. Highlights Stevia strains can be grown in temperate climate under the tunnel and in the field. Differences between stevia strains resulted from differences in metabolic activity. High photosynthetic efficiency is correlated with high steviol glycosides level. Steviol glycosides might function in the protection of photosynthetic apparatus.

    Abstract Basil produces important compounds for the industrial manufacture of medicines, cosmetics, and food that are obtained by conventional production techniques. In vitro cultivation has contributed to the increasing reliability of the production, and efficient isolation, of target compounds independent of seasonal factors. We sought to assess the effects of copper sulfate on seedling growth and the elicitation of chemical constituents of the essential oil of basil leaves cultivated in vitro . Basil seedlings were grown in Murashige and Skoog (MS) medium enriched with 25 and 75 μM CuSO 4 , as well as in control treatments. Essential oils obtained from the hydrodistillation of dried leaves were subjected to GC–MS analysis. The GC–MS and PCA analyses indicated the presence of two predominant volatile groups: Phenylpropanoids (77.81%) in the 25 μM CuSO 4 treatment, with eugenol and methyl eugenol as major components, with industrial and pharmacological importance; and Monoterpenes (69.72%), in the 75 μMCuSO 4 treatment and control, subdivided into monoterpene hydrocarbons (19.36%) and oxygenated monoterpenes (50.36%), with 1,8 cineole and linalool as major components.MS medium enriched with 25 μM CuSO 4 resulted in seedlings with longer and more numerous leaves, which would be important for oil extraction. That Cu concentration probably affected the phenylpropanoid metabolic pathway, which is triggered mainly under plant stress situations. Highlights The use of 25 μM CuSO 4 clearly increased the production of phenylpropanoids (77.81%). The use of 25 μM CuSO 4 clearly increased the components methyl eugenol (41.05%) and eugenol (36.37%). Some compounds were only encountered in the essential oil of basil leaves cultivated with 25 μM CuSO 4 . The addition of CuSO 4 25 μm to the MS medium promoted increased shoot height and greater numbers of leaves.

    Abstract Shelf-life quality was improved when Cardinal table grapes ( Vitis vinifera L.) were pretreated with 20 kPa of CO 2 for three days at the beginning of a long-term cold storage. This pretreatment was effective in avoiding postharvest losses of cv. Cardinal grapes in terms of water loss, oxidative damage and disease prevention. To elucidate those physiological and biochemical factors involved in preserving the postharvest shelf-life quality of table grapes, we studied the expression pattern of defense proteins such as pathogenesis-related proteins (PRs) and dehydrins, as well as the profile of protective osmolytes. The efficacy of a short-term high CO 2 pretreatment in reducing fungal disease could be mediated by the increase in the low molecular mass chitinase isoform of 16 kDa, which is up-regulated in the skin of CO 2 -treated grapes in parallel with the shelf-life fungal decay control. In addition, the increasing accumulation of a 22 kDa dehydrin isoform and the endogenous levels of organic osmolytes proline and glycine betaine in fruit stored at 20 °C (mainly in CO 2 -treated fruit) revealed that these protective biomolecules might play a more effective role in maintaining the structural and cellular homeostasis of table grapes after the shelf-life period, helping to reduce water loss and membrane oxidative damage (malondialdehyde accumulation) associated with the senescence-related disorders of postharvest table grapes. Highlights Short-term high CO 2 reduces shelf-life water loss and decay in Cardinal grapes. PR and dehydrin isoforms differentially regulate by postharvest environmental cues. A skin chitinase isoform of 16 kDa related with shelf-life fungal decay control. Proline and glycine betaine associated with reduced berries water loss profile. GABA and trehalose levels are cold and CO 2 regulated in skin Cardinal grapes.

    Abstract Hazel ( Corylus spp.) is the most economically important species in the Betulaceae family. Frequent ovary abortion during the prefertilization stage causes the high drop ratio of pistillate flowers and smaller fruit numbers in a fruit cluster, resulting in yield loss. To better understand the mechanism of ovary abortion formation in hazel, we conducted transcriptomic and proteomic analyses and identified genes and proteins that were altered in response to ovary abortion. A total of 89,846 unigenes and 4343 proteins were identified using RNA-seq and iTRAQ technology, respectively. Among them, 1895 unigenes and 710 proteins were differentially expressed and accumulated in the developing and abortive ovary respectively. Furthermore, we employed the Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis, revealing pathways that are significantly enriched in both transcriptomic and proteomic assays. These include the phenylalanine metabolic pathway, biosynthesis of phenylpropanoid, biosynthesis of secondary metabolites, and ascorbate and aldarate metabolism. Transcriptome-proteome integrative analysis revealed 42 correlations. Among these, 32 correlations with same changing trend (that are involved in metabolism stress response, vascular strand development, water transport, and seed development) are likely associated with abortive ovary formation. Importantly, ethylene (ETH), jasmonic acid (JA), and salicylic acid (SA) signal transduction pathways may contribute to the regulation of the abortive ovary formation via the up-regulation of ethylene-responsive transcription factor 1 (ERF1/2), jasmonate ZIM domain-containing protein (JAZ), transcription factor MYC2 (MYC2), transcription factor (TGA), and pathogenesis-related protein 1(PR-1). Our work will facilitate the identification of ovary abortion related genes and proteins and provide insights into the molecular mechanism of fruit development.

    Abstract The annual fluctuations in olive crop load due to alternate bearing and other factors often lead to large differences in fruit size and oil content between years at harvest. A better understanding of how fruit parameters respond to the different leaf: fruit (i.e., source: sink) ratios that occur with contrasting crop loads would provide important information for crop management. Thus, the primary objectives of this study conducted with the cv. Arauco in three growing seasons were to: 1) determine the weight and size responses of the fruit and its main tissues, mesocarp (pulp) and endocarp (pit), to crop load; and 2) obtain relationships between different estimates of the source: sink ratio versus various fruit and oil parameters. Fruit thinning was performed by hand on uniform trees with high initial crop loads four weeks after full bloom the first season to obtain different crop loads at harvest. The thinning percentages the first season were 24%, 48% and 87%, along with an unthinned control. The same trees were then monitored the following two seasons without any further thinning. Fruit were sampled at harvest each season to determine fruit and tissue weights and diameters, oil weight per fruit, and oil concentration (%). Fruit weight was reduced 30–40% by high crop loads in each growing season with the mesocarp being much more affected than the endocarp. Oil weight per fruit (−50%) showed a somewhat greater reduction than fruit weight to crop load due to both fruit diameters and fruit oil concentration being decreased at high crop loads. Fruit and tissue weights and oil weight per fruit all displayed bilinear functions versus source: sink ratio when the source was expressed as canopy volume (a surrogate for leaf area) and sink on both a fruit number and glucose equivalent (GE) basis. Source limited fruit growth at both medium and high crop loads due to limited photoassimilate availability based on the bilinear functions, and the slope of the endocarp response to source: sink ratio was 15 times less than that of the mesocarp when expressed on a GE basis. A quantitative comparison with previously published studies indicated that maximum fruit weight appears to be obtained in olive between 1–2 m 2 of leaf area per kg of GE. The bilinear relationships of source: sink ratio versus fruit weight observed in this study could contribute to crop modelling, and further research concerning how and when the mesocarp and endocarp respond to crop load is needed to aid crop management in obtaining sufficient fruit size and quality for table olive cultivars. Highlights Fruit weight and oil weight per fruit were decreased by crop load in cv. Arauco. Mesocarp weight was more affected than endocarp weight by crop load. Fruit and oil weights were source limited at medium and high crop loads. Fruit glucose units are an alternative to fruit number in source: sink calculations.

    Abstract Variation in leaf morphology and physiological characteristics was studied in six genotypes of Annona , namely A. atemoya , A. cherimola , A. glabra , A. muricata , A. reticulata , and A. squamosa (‘Balanagar’). The genotypes differed significantly in their leaf morphology and gas exchange: specific leaf weight was maximum in A. muricata and A. reticulata ; leaf area, in A. cherimola ; and net photosynthesis, in A. squamosa . Water use efficiency, relative water content, epicuticular wax content, and stomatal density on abaxial and adaxial surfaces of leaves were maximum in A. glabra (although the density was equally high in A. squamosa ) whereas chlorophyll a , chlorophyll b , and total chlorophyll content were maximum in A. squamosa . These differences may prove relevant in selecting Annona genotypes for adaptation to different agro-climatic regions. Highlights The Annona genotypes ( A. cherimola Mill., A. glabra L., A. muricata L., A. reticulata L., A. atemoya , and A. squamosa L. ‘Balanagar’) differed significantly in leaf morphology, gas exchange, chlorophyll content, and other related characters. Some of Annona genotypes with distinct traits could be important for selecting or breeding of rootstocks or varieties adaptable to a wide range of soil and environmental conditions.

    Abstract In recent years, Carignan grapevines in the Maule Valley have been rediscovered by viticulturist and winemakers, producing very interesting wines and well recognized worldwide. Phenolic compounds are responsible for the sensory attributes of wines, such as colour, bitterness and flavour. Their composition depends of several factors such as variety, soil attributes, climate conditions, viticultural practices, oenological procedures, among others. The aim was to study wine phenolic composition from Carignan grapevines ungrafted and grafted with PaIs, growing in ten sites of the Maule Valley (Chile). Phenolic compounds were analysed by HPLC-DAD. The results showed that water holding capacity and soil depth affected weight of 100 berries and consequently wine phenolic composition. Besides, climatic conditions affected alcoholic degree more than phenolic compounds in wines. Rootstock barely affected phenolic content. These findings are of importance for the Chilean wine industry in relation to the viticultural management and the characterization of the phenolic composition of wines made from the variety, regarding location and rootstock, within the Maule Valley. Highlights The study of minority grapevine varieties has become relevant in the wine industry. Water-holding capacity and soil depth affected weight of 100 berries and phenolic content. Grapes from CurtidurIa, Melozal and Valdivia presented high phenolic content. Climatic conditions affected alcoholic degree more than phenolic compounds in wines. Rootstock effect was affected by the variability of the sites by climate and soil.

    Abstract The effect of harvest time at different ripening stages of fruit influences quality of olive oil. Therefore, the current investigations were conducted during 2013 and 2014 to explore the effects of five different harvesting times (mid- and late-April, mid- and late-May and mid-June) on chemical and sensory attributes of Frantoio and Manzanilla olive oil. The fatty acids of olive oil showed significant increase (palmitic acid, stearic acid, linoleic acid and PUFA) or decrease (oleic acid, MUFA, and MUFA:PUFA ratio) with the delay in harvesting irrespective of the cultivars. A significant gradual decrease was noted in major polyphenol compounds from the first to the fifth harvest. The concentration of phenolic compounds was comparatively higher in the fruit harvested in 2014. The sensory attributes of oil in both cultivars deteriorated with the delay of harvesting, with water stress possibly influencing the bitterness of the fruit in 2014. The harvesting in early part of winter under Mediterranean climate produced olive oil with better chemical and sensory attributes. Higher concentrations of phenolic compounds were observed in 2014 with less rainfall; however, the trend of declining concentration on phenolics from the first to the fifth harvest was comparatively prominent in 2014 than 2013. Highlights Delayed harvest increases palmitic acid, stearic acid, linoleic acid and PUFA in oil. Delayed harvest decreases oleic acid, MUFA, and MUFA:PUFA ratio) in oil. Major polyphenolic compounds in oil decrease with the delay of harvesting. Sensory attributes of oil in both cultivars deteriorated with the delay of harvesting.
