Abstract: Chilling injury in cucumber is the major issue under low temperature storage, which substantially affects cosmetic quality and market value of fruits. Present study was aimed to assess the effect of L-arginine to alleviate surface pitting caused due to chilling injury and response of various quality attributes during cold storage (5 ± 1 °C RH 90 ± 5%). Cucumber cv. ‘7003’ fruits were treated with different concentrations of L-arginine (0.0, 0.5, 1.0 and 1.5 mM) and stored for 16 days. Fruits were removed at 4 days storage interval followed by 1 day of conditioning (22 ± 2 °C) before quality analysis. Visual quality, fruit colour, decay, fruit weight loss, firmness, chilling injury (CI), electrolyte leakage, taste, texture, flavour, aroma, soluble solids content (SSC), titratable acidity (TA), sugar: acid ratio (SSC/TA ratio) and ascorbic acid content were measured for cucumber fruits. Overall, it was noted that L-arginine treated fruits showed lower fruit weight loss and electrolyte leakage, and maintained taste, texture, aroma, SSC, and sugar: acid ratio during storage. Fruits treated with 0.5 mM L-arginine had significantly reduced chilling injury and decay, maintained fruit colour, firmness and flavour, and displayed higher ascorbic acid content compared with control. Conclusively, pre-storage application of L-arginine (0.5 mM) can be employed as promising technique to alleviate postharvest chilling injury and maintain fruit quality of cucumber under cold storage.

Abstract: Shape and size are important features of fruits. Studies using tomatoes expressing yeast Spermidine Synthase under either a constitutive or a fruit-ripening promoter showed obovoid fruit phenotype compared to spherical fruit in controls, suggesting that polyamines (PAs) have a role in fruit shape. The obovoid fruit pericarp exhibited decreased cell layers and pericarp thickness compared to wild-type fruit. Transgenic floral buds and ovaries accumulated higher levels of free PAs, with the bound form of PAs being predominant. Transcripts of the fruit shape genes, SUN1 and OVATE, and those of CDKB2, CYCB2, KRP1 and WEE1 genes increased significantly in the transgenic ovaries 2 and 5 days after pollination (DAP). The levels of cell expansion genes CCS52A/B increased at 10 and 20 DAP in the transgenic fruits and exhibited negative correlation with free or bound forms of PAs. In addition, the cell layers and pericarp thickness of the transgenic fruits were inversely associated with free or bound PAs in 10 and 20 DAP transgenic ovaries. Collectively, these results provide evidence for a linkage between PA homeostasis and expression patterns of fruit shape, cell ision, and cell expansion genes during early fruit development, and suggest role(s) of PAs in tomato fruit architecture.
