硝基氯苯胁迫对小麦萌发的影响
Influences of 2,4-Dinitrochlorobenzene Stress on the Germination of Wheat
摘要
Abstract
[Objective] The purpose was to study the influences of stress from 2, 4-dinitrochlorobenzene with different concn. on the seed germination and physiological characteristics of different wheat varieties. [Method] With Wanmai 52, Xinong 979 and Han 6172 as tested wheat varieties, the influences of 2, 4-dinitrochlorobenzene on the seed germination and seedling growth of wheat were studied through germination and sowing experiments. [Result] Under the stress from 2, 4-dinitrochlorobenzene with same concn., the germination rate and emergence rate of Xinong 979 were highest and its roots were most developed. Under the stress from 2, 4-dinitrochlorobenzene with same concn., the chlorophyll contents in both Xinong 979 and Wanmai 52 were higher than that in Han 6172, indicating that their photosynthetic capacity was stronger than that of Han 6172. Under the stress from 2, 4-dinitrochlorobenzene with same concn., the proline content in Xinong 979 was lowest. Under the stress from 2, 4-dinitrochlorobenzene with same concn., the MDA content in Xinong 979 was lowest and that in Han 6172 was highest, showing that the stress resistance of Xinong 979 to 2, 4-dinitrochlorobenzene stress was strongest. [Conclusion] The germination and emergence of wheat were inhibited obviously by 2, 4-dinitrochlorobenzene and the stress resistance of Xinong 979 was strongest.关键词
