Abstract:
Taking the processing tomato cultivar ‘Ouyaduo’ as material，different exogenous sodium nitroprussid（0.05，0.10，0.50，1.00,1.50 mmol/L）on tomato seed under low temperature (18±1)℃ and different exogenous sodium nitroprussid（0.1，0.5，1.0，1.5 mmol/L）on growth of tomato seedling under low temperature (12±1)℃/(8±1)℃ were used in this experiment，to study the effects of exogenous NO on tomato seed germination and growth of tomato seedling.The results showed that SNP of 0.05 and 0.10 mmol/L could increase tomato seed’s germination rate，germination energy，germination index and activity index，the optimum concentration was 0.05 mmol/L SNP of 0.10-1.00 mmol/L differently alleviated the restrain of height，thickness，number of leaves，fresh and dry weight and root activity on growth of tomato seedling，the optimum concentration of SNP for root activity was 0.50 mmol/L，other indexes were 1.00 mmol/L．
