Abstract:
Color pepper is difficult to sprout less than 15 ℃,and the low temperature in early spring influenced seed germination and growth.In order to study the effect of brassinolide on seed germination and seedling cold resistance,by 0.01 mg?L-1,0.05 mg?L-1,0.10 mg?L-1,0.50 mg?L-1 brassinolide treatment on seeds and seedlings of pepper,pepper seed germination rate,germination potential,germination index and vigor index were measured.SOD,POD,CAT activities of pepper seedlings,proline and MDA content were determined.The results showed that when the brassinolide concentration with 0.10 mg?L-1 could promote germination rate of cherry color pepper,when brassinolide concentration with 0.05 mg?L-1 and 0.10 mg?L-1 could promote activities of SOD,POD,CAT,and protein content was increased,but MDA content was decreased.So suitable concentration of brassinolide could promote germination rate of cherry color pepper,increase ability to tolerance cold temperature.
