伊犁绢蒿根系贮存性营养物质和渗透调节物质季节变化及对刈割强度的响应
Season Change and Response on Stored Nutrition Matter and Osmosis Regulating Substances of Mowing Intensities on Roots in Seriphidum transiliense
摘要
Abstract
[ Objective]An experiment was carried out to research the response of mowing intensity of roots in Seriphidum transiliease , which is mainly contained in nutrition storage substance and osmosis regulating substance .[Method] The experiment uses anthrone colorimetry, ninhydrin colorimetry, coomassie brilliant blue colorimetry respectively to determinate water soluble sugar , starch , praline soluhle protein . [ Result] ( 1) The water soluble sugar in the roots of S . transliense had the seasonal dynamic changes, that is "double - peak curve" dynamic changes,the starch has a "inverted S" dynamic changes, the free praline has a irregular "single - peak curve" dynamic changes , the soluble protein has a "microwave curve" dynamic changes, and the peak of occurring at the same time in all treatments; (2)The change trend of the water soluble sugar and starch is opposite in the roots of S.transiliense. Before the nutrition substance accumulats (15 September) it presents a complementary state, but starch content is higher than water soluble sugar. (3) The response of nutition substance and osmosis regulating substance all have hysteretic property, and compared with that the soluble protein, it has a shorter hysteretic property. (4) The indexes in different mowing intensity have a significant difference ( P ＜ 0 . 05) , and some have extremely significant differences ( P ＜ 0. 01). [ Conclusion] Mowing intensity has a significant effect on physiological fastness of the roots of Seriphidum transiliense .关键词
