dc.description.abstractThe present study was conducted on brinjal (Solanum melongena L.) seeds var. Punjab nagina. The quality of brinjal seeds in-terms of vigour and viability severely declines as a result of natural ageing during storage between harvesting and next sowing season. The objective of this study was to evaluate the effect of various priming treatments on the quality and storability of brinjal seeds. The freshly harvested seed was divided into two lots. One of these seed lots was subjected to accelerated ageing to obtain low vigour seed and the other lot was considered to be high vigour. The high and low vigour seeds were primed with KNO3 (1%), GA3 (100ppm), KH2PO4 (0.1M), PEG 6000 (30%) and H2O for 12 hours at 25oC. Thereafter, the seeds were stored in moisture impervious bags for 12 months in a refrigerator (4C). The objective was to observe whether the priming treatments improve the seed vigour and also retain the advantages obtained from priming during storage. The seeds were drawn at three-monthly intervals, viz. zero, three, six, nine and twelve months of storage. 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 (Total soluble sugars, total soluble proteins, α-amylase activity and membrane stability index, starch content, total free aminoacids) observations were recorded. With an increase in storage duration, a decline in physiological and biochemical aspects of seed quality was observed in both high and low vigour seeds. All the priming treatments improved the germination related parameters in both high and low vigour seeds over control but the extent of improvement varied. Seed priming with GA3 (100ppm) followed by priming with KNO3 (1%) were found to be the best treatments for both high and low vigour seeds even after storage for 12 months.en_US
