Effect of storage condition on seed germination and viability constant value of lentil (Lens culinaris) and chickpea (Cicer arientinum)

Effect of storage temperature, seed moisture content and storage duration was studied in a factorial experiment with 3 factors include temperature(5, 19 and 33˚C), moisture content(5, 12 and 19%) and time (1, 2, 3, 4, 5 and 6 month) in completely randomized design. After sampling at the end of each month, standard germination test and electrical conductivity test were done. The results showed that interaction of time, temperature and moisture content were significantly affected the percent germination, germination rate and electrical conductivity of seed exudates. Lowest deterioration level was in 5% moisture content and 5˚C after one month of storage which percent germination was reduced from 98% to 92% in lentil and from 99% to 98% in chickpea. With time spending electrical conductivity was reduced. V= Ki- p /10KE – CW log10 m – CH t – CQ t is seed viability equation and KE, CW, CH and CQ are viability constant which were calculated with data from six month storage of seeds and their value for lentil and chickpea were 4.2919, 1.4928, 0.0244 and 0.00017 and 8.5067, 4.5238, 0.0486 and 0.00028 accordingly.
