    ABSTRACT: Five inbred lines of tomato were crossed in a half diallel fashion to estimate the combining ability, mode of gene action, extent of heterobeltiosis and dominance effects in the inheritance of fruit yield, processing qualities and disease severity traits. A preponderance of non-additive gene action was detected for all studied characters except fruit weight, indicating that heterosis breeding is an appropriate strategy for their improvement. Maximum heterobeltiosis was observed for the percent disease index (PDI) of tomato leaf curl viruses (ToLCV), followed by the number of locules per fruit, PDI of early blight, fruit yield per plant, lycopene content of fruit, vitamin C content of fruit, total soluble solids content of fruit and acidity content of fruit. Partial- to over-dominance effects were involved in the inheritance of the studied traits. Three lines (CLN 2777E, BCT-115 and CLN 2777F) were identified as potential donors. We recommend that two hybrids (CLN 2777 F × CLN 2777 E and CLN 2777E × Ailsa Craig fulgens) would be appropriate for commercial use following further evaluation of their traits, as they exhibit desirable horticultural traits, particularly in the tropics.

    ABSTRACT: A polymerase chain reaction (PCR) assay was developed that amplified a 170-bp fragment of the intergenic spacer region of Sclerotinia sclerotiorum, the cause of white mould. Sensitivity was 10 S. sclerotiorum ascospores per DNA extraction (0.2 ascospores per PCR reaction). The presence of soil did not affect sensitivity at 50, 100 and 500 ascospores/DNA extraction, but reduced sensitivity at 25 and 10 ascospores/DNA extraction by 10% and 30%, respectively. The assay did not amplify DNA of Botrytis cinerea but detected S. minor and S. trifoliorum. Utility of the test for detection of S. sclerotiorum ascospores in bean fields was demonstrated using rotating impaction samplers over two seasons. The use of the test in combination with an impaction sampler may provide benefits in time, sensitivity and specificity compared with visual identification and enumeration of spores from traps only. This system may provide an opportunity to schedule fungicides during periods of inoculum presence for disease management.

    ABSTRACT: Resveratrols and flavonoids have important beneficial roles in plants and to humans. The grape family (Vitaceae) is one of several families that can biosynthesise both resveratrols and flavonoids. Previous research has shown that UV-C may induce the biosynthesis of resveratrols in the fruit of grape. But little is known about the UV-C-induced biosynthesis of resveratrols and flavonoids in grape leaves. This study demonstrated that the biosynthesis of resveratrol in grape leaves strongly increased in response to UV-C irradiation. The largest contribution to total resveratrols was trans-resveratrol. The expression of related genes, including PAL, C4H, 4CL and STS, increased and peaked 6-12 h after treatment, earlier than the peak of total resveratrol. In contrast, total flavonoid content and the expression of the key gene CHS was not affected by UV-C radiation, staying at a low level after UV-C irradiation. In summary, there is a differential response to UV-C radiation for the biosynthesis of stilbenes and flavonoids in grape leaves.

    ABSTRACT: Resveratrol is well known for its strong antioxidant properties. To accelerate research on resveratrol metabolism and to evaluate the genetic potential for breeding, the stilbenoid contents of four tissues (leaf and berry skin, flesh and seed) were examined in 21 accessions of six wild Chinese grapevine species (Vitis quinquangularis, V. romanetii, V. piasezkii, V. shenxiensis, V. amurensis and V. davidii). Resveratrol derivatives in V. quinquangularis, V. romanetii, V. piasezkii and V. shenxiensis are reported for the first time. Three kinds of stilbenoid (trans-resveratrol, cis-piceid and trans-piceid) were detected in the berry skins, flesh, seeds and leaves but cis-resveratrol was found to be absent. Stilbenoid content was predominantly affected by genetic background and by tissue type. In most accessions, berry skins produced the highest total stilbenoid, followed by leaves, seeds and flesh. As a proportion, cis-piceid was the major stilbenoid component in berry skins, seeds and leaves, whereas trans-piceid was the major component in the flesh.

    ABSTRACT: Infection by Botrytis cinerea is a major cause of postharvest decay in strawberries. The efficacy of baby corn fermented vinegar (BFV) for growth inhibition of B. cinerea was investigated by diffusing 0%-0.225% acetic acid from BFV or glacial acetic acid into potato dextrose agar. BFV containing 0.225% acetic acid completely inhibited the growth of B. cinerea. Strawberry-flavoured baby corn fermented vinegar (SF-BFV) was developed to mask unfavourable smells caused by BFV. The effectiveness of BFV liquid and vapour for controlling postharvest decay in strawberries was evaluated along with associated sensory analyses. Taste panellists readily accepted fruit that had been sprayed with SF-BFV or exposed to BFV vapour, both treatments that significantly reduced fruit decay. Strawberries inoculated with B. cinerea were also tested. Shelf life at 4 °C of strawberries sprayed with SF-BFV was extended to 7 days while that of fruit exposed to BFV vapour was extended to 11 days.

    ABSTRACT: Tomato potato psyllid (TPP; Bactericera cockerelli) is a serious pest of solanaceous crops in New Zealand. Control of TPP is currently dominated by synthetic biocides, although this method is curative and does not always prevent transmission of TPP-vectored plant diseases. This study evaluated mesh crop covers as non-chemical alternatives for controlling TPP in potato crops. Over two growing seasons in Canterbury, New Zealand, potatoes growing under mesh covers were found to have reduced numbers of TPP nymphs and adults, increased tuber size, increased overall yield and enhanced storage potential compared with uncovered plots. There was also a slight reduction in potato blight spores under mesh, and the actual occurrence of blight was slightly reduced in one trial. The results of this study indicate that mesh crop covers could provide a viable option for potato growers who wish to protect their crops from TPP without using chemical insecticides.

    ABSTRACT: Photosynthetic rate and the kernel-filling process are two crucial determinants of kernel yield in cereal crops. In the present study, the dynamic photosynthetic rates (Pn), kernel-filling characteristics, and kernel-filling rate and duration of five big-spike wheat lines (Triticum aestivum; 2005, 2026, 2037, 2038 and 2040) were compared with a control multiple-spike cultivar (Xi'nong 979) in 2010–11 and 2011–12. The 1000-kernel weight of the upper, middle and basal parts of the spike experienced a ‘slow-fast-slow’ pattern of growth from flowering to maturity. The big-spike lines had greater dry matter accumulations than the control cultivar 46 days after flowering, and also had higher kernel-filling rates in the basal part of the spike during the late growth period and greater kernel weights in the middle part of the spike throughout the entire kernel-filling process. The kernel-filling rates of the different parts of the spike during the three kernel-filling stages were ranked in the order of V2 (rapidly increasing kernel-filling stage) > V3 (slowly increasing kernel-filling stage) > V1 (moderately increasing kernel-filling stage). The mean Pn for each of the big-spike lines was lower than that of the control cultivar. These results indicate that the plumpness, size and weight of kernels produced by the big-spike lines can likely be increased by simultaneously increasing the photosynthetic rate and the kernel-filling duration during the late kernel-filling stage.

    ABSTRACT: Extending the storage potential of feijoa would enable export to new markets. This work investigates the effect of combinations of 1-methylcyclopropene (1-MCP) and reduced oxygen atmospheres at 4 °C on feijoa quality. After harvest, feijoa were treated at 20 °C with 500 nL L−1 for 3 h or 1000 nL L−1 for 12 h of 1-MCP and air (as a control). Subsequent storage conditions at 4 °C were either: 2 kPa O2 and 0 kPa CO2; 5 kPa O2 and 0 kPa CO2; or air (as a control). Fruit were subsequently assessed fortnightly for up to 10 weeks. 1-MCP treatment was found to have no impact on delaying deterioration during storage. Reduced oxygen atmospheres delayed loss of firmness and titratable acidity during storage. However, after 4 weeks of storage, surface injury was most severe in the 2 kPa O2 treatment. Further research on extending storage life of feijoa is required.

    ABSTRACT: The changes in endogenous abscisic acid (ABA) content during ‘Hanagosho’ persimmon (Diospyros kaki Thunb.) development and maturation, as well as the effects of ABA, nordihydroguaiaretic acid (NDGA), 1-methylcyclopropene (1-MCP) application and polyethylene film package treatment on detached young fruit during fruit softening and senescence were investigated. The results showed that the ABA content in both peel and pulp peaked at 30 and 140 days after full bloom (DAFB). Moreover, the ABA content in peel at 30 and 140 DAFB was 17 and 29 times higher than in pulp, respectively. Dehydration in detached fruits induced the production of ABA and ethylene, which further led to fruit softening, and during this process ABA peaked earlier than ethylene. Expressions of the ethylene biosynthesis gene DkACS2 and ethylene oxidase gene DkACO1 were increased by the ABA treatment and their expression peaks also appeared earlier. However, expressions of DkACS2 and DkACO1 were down-regulated by the application of NDGA and 1-MCP, and their expression peaks were delayed. The peak time of 9-cis-epoxycarotenoid dioxygenase genes (DkNCED1) expression was not advanced under ABA, NDGA and 1-MCP treatments. In package-treated fruits, expressions of DkNCED1, DkACS2 and DkACO1 were significantly down-regulated and their expression peaks were delayed. In conclusion, we propose that dehydration could induce the expression of DkNCED1 and trigger ABA biosynthesis, while ABA could induce the expressions of DkACS2 and DkACO1, which initiates the biosynthesis of ethylene, consequently accelerating fruit softening and ripening.

    ABSTRACT: An experiment was conducted to investigate the effects of deficit irrigation on yield and tree growth of young apricot trees (Prunus armeniaca L. cv. Ninfa) during three growing seasons with three irrigation intervals (7, 14 and 21 days) and five irrigation levels based on reduction coefficients (Kcp) of class A pan evaporation (0.0, 0.25, 0.50, 0.75 and 1.00). Growth and yield variables such as trunk diameter, mean branch length, volume of tree, total number of fruit, mean fruit weight, total fruit yields of trees, evapotranspiration and water use efficiencies were determined. While the irrigation interval treatments had significant effects on trunk diameters and branch lengths of the trees, the irrigation level treatments significantly affected all the tree growth variables. Variation in irrigation level also affected yield, with yield and fruit size increasing as irrigation increased up to at least 0.75 of pan evaporation. The treatment with 25% water deficit and a 14-day irrigation interval is suggested as the most suitable irrigation strategy for young apricot trees under a Mediterranean climate.
