低磷胁迫对巴西橡胶树幼苗保护酶活性的影响
Study on the Protective Enzyme Activity of the Hevea Seedling Under Low Phosphorus Stress
摘要
Abstract
By the hydroponic culture method, the effect of low phosphorus stress on the protective enzyme system of Hevea seedlings were studied. The results showed that MAD content and SOD activities were increased under the low phosphorus stress, and higher than the CK in 84 days; POD, CAT activities began to increasing in 42 days, and both higher than CK at the 42nd day, decreased in 42~84 days and lower than the CK at the 84th Day. MAD content was changed in the roots less than in other organs, while the SOD, POD and CAT activities changed a lot more than in other organs. Root was much more sensitive by the low phosphorus stress than other organs.关键词
