Abstract
Plant breeders are still doing best for identifying efficient screening tools for overcome heat temperature during germination without any adverse effect on seed viability. The aims of study was to determine the efficiency of soaking old seeds (natural ageing for two years) in some antioxidants namely; calcium chloride, selenium, zinc sulfate in addition to water and dry seed as control under different temperature regimes namely; 15, 20, 25, 30 and 35 oC. The results revealed that low temperature negatively affected seed quality especially germination percentage and seedling establishment whereas, high temperature gave the highest values to germinability. Calcium chloride 1% was more efficient to all studied traits followed by 50 ppm selenium compared with control (dry seed).The interaction between factors revealed that 1% calcium chloride more efficient at different temperature regimes (low and high temperatures).The results suggest that soaking old seeds in calcium chloride for 24 h can mitigate effects of different temperature regimes and keep quality of old rice seeds. Also, can save costs and time of farmers.
