Seeds of different plant species of Cholistan desert such as Capparis decidua, Salvadora oleiodes and Prosopis cineraria were allowed to germinate at various temperature regimes and their percent age germination was monitored. Results show that optimal germination temperatures for C. decidua is 20°C (90% germination in 8 days) and for P. cineraria (65% in 10 days) and S. oleiodes (85% in 4 days) is 30°C. Imbibition of P. cineraria in sand at 25°C has been effective to get 80 percent seeds germinated. Electrical conductance (μS/cm/10 seeds) measured during early hours/days of imbibition has been correlated with the increase in fresh weights of imbibing seeds, though there is decrease in the rate of electrolytes leakage (μS/cm/hour/10 seeds) with increase in imbibitional time. Work is in progress on the biochemical aspects of these early hours/days of seed germination.]]>Ifzal, S.M., R. Ali and Z.H. Zaidi,1982Salvadora oleoids.]]>Chopra, G.R., A.C. Jain and T.R.
