This work was conducted (i) to measure the electrical conductance of dry and imbibing seeda, (ii) to monitor the per cent age germination and spread of germination of these species at varying temperature conditions and (iii) to find the optimal germination conditions so that some biochemical and biomolecular studies could be carried out in near future. Seeds of different plant species of Cholistan desert such as Capparis decidua, Salvadora oleides and prosopis cineraria were allowed to germinate at various temperature regimes and their per cent age germination was monitored. Results show that optimal germination temperature 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 per cent seeds germination. Electrical conductance (μS/cm/10 seeds) measured during early hours/days of imbibition has been correlated with the increase in fresh weight of imbibing seeds, through there is decrease in the rate of electrolytes leakage ((μS/cm/hours/10 seeds) with increase in imbibitional time. Work is in progress on the biochemical aspects of these early hours/days of seed germination. |
