dc.description.abstractThe present study was conducted on cucumber (Cucumis sativus L.) seeds var. Punjab Naveen with the objective to evaluate the effect of various priming treatments on the quality and storability of seeds. The freshly harvested seeds were subjected to different concentrations of priming treatments viz. K2HPO4, KH2PO4, Hydroxyurea, GA3, ethrel, benzyl adenine, mimosine, KNO3, ZnSO4 and H2O for 6 hours at 25°C and various physiological (germination percentage, speed of germination, mean days to germination, seedling length, root length, shoot length, seedling dry weight and seedling vigour index) and biochemical parameters (Total soluble sugars, total soluble proteins, α-amylase activity, dehydrogenase activity, total phenol content, catalase activity, peroxidase activity, lipid peroxidation and membrane stability index) were recorded. Seed priming treatments ethrel (50ppm) followed by KNO3 (1.5%) and mimosine (100µM) were the most effective treatments in improving percent and speed of germination and reducing mean germination time immediately after priming. The best sixteen treatments along with control were selected thereafter and seeds were stored in cloth bags for 12 months in a refrigerator (4⁰C) to validate the effect of priming on seed quality during the storage period. The data were collected at bimonthly intervals, viz. zero, two, four, six, eight, ten and twelve months of storage. It was observed that with an increase in storage duration, an increase in physiological and biochemical aspects of seed quality in primed seeds. An increase in parameters was observed upto ten months of storage and sharp decline observed thereafter. All the priming treatments improved the germination related parameters in primed seeds over control but the extent of improvement varied. Seed priming with mimosine (200µM) followed by priming with KNO3 (1.5%) and KH2PO4 (10-5M) were found to be the best treatments for cucumber seeds even after storage for 12 months.
