金雀花扦插生根过程中内源激素动态变化
The content changes of the endogenous hormone during the adventitious rooting of Cytisus scoparius cutting
摘要
Abstract
In order to reveal the rooting mechanism of Cytisus scoparius,the variations of endogenous hormones contents with the method of ELISA was analyzed,taken 2-year-old hardwood steckling as materials. The result showed that:compared with CK,the rooting period of cuttings treated with 900 mg/ L IAA was clearly shortened. Before forming a large number of adventitious roots,the variations of endogenous hormones contents emerged with inverted“V”shape except treated with ABA. Before the valley or peak in curves of endogenous hormones changes appeared,the contents of IAA,IAA/ ZT,IAA/ABA,ZT/ ABA in cuttings treated with IAA were higher than that in CK,however the contents of ABA in which was lower than that in CK. The valley or peak in curves from cuttings treated by IAA and CK appeared on the 10th day and 15th day respectively,which accorded to rooting dynamic.关键词
