耕层柽柳根生长分布和管花肉苁蓉接种的WINRHIZO扫描观察
Monitor of tamarisk root growth and Cistanche tubulosa infection in soil arable layer by WINRHIZO
摘要
Abstract
In order to study the interaction of tamarisk root and Cistanche tubulosa in the soil arable layer,we used WINRHIZO scanner system to determine the tamarisk root growth and detect the time when the C.tubulosa would infect the host root;we measured the echinacoside,verbascoside and soluble sugar of the C.tubulosa by HPLC and spectrophotometry.The result showed：the tamarisk stem cuttings began to develop the root 15 days after cuttage,and the growth curve followed ＂S＂ curve;the C.tubulosa began to infect with tamarisk on day 60 after cuttage for the first time.Similarly,the infection rate of the C.tubulosa followed ＂S＂ curve;initially,the growth of C.tubulosa plant grew slower during the 90 days of infection（indicated by lighter dry weight）,then the C.tubulosa began to grow faster after the day 90,and the dry weight of the single plant could reach to as high as 16 gram,and the amount of the echinacoside,verbascoside and soluble sugar were 9.6%,1.7% and 11.3% separately.Our study indicated that the WINRHIZO scanner system could be be used as a new approach to detect the parasite plant and the host plant in the soil arable layer and provide more detailed information on the infection dynamics and the effective factors during the complicated infection processes.关键词
