Studies On The Components Of Haloxlon Root's Secretion And The Haustorium Germination Of Cistanche Deserticola Seeds

Cistanche deserticola, a Orobanchaceae Cistanche perennial parasitic plant,has many specific medical values.It's host plant is Haloxlon which is an useful plant for stabilizing sand. Cistanche seeds in the nearby of the haloxlon root can germinate haustorium, through which it invade Haloxlon's vascular bundle tissue and absorbs nutrition. It is of great theorietical and practical significance that elucidate the parasitic mechanism to solve and develop the production of Cistanche deserticola. In the experiment,we used the method of GC-MS to mensurate the component of Haloxlon root's secretion.At the same time, large numbers of tissue culture experiments of Cistanche seeds germination wre done.The results showed: (1) The components of Haloxlon root's secretion of four-week and eight-week seedlings were analogical,that included Hydrocarbons, Alcohols, Aldehydes, Ketones, Guinones, Phenolic, Organic acid, Aromaticity, Esters, ect. But the idiographic substance is different. (2) 2,5-dihydroxy-P-Benzoquinone and 2,6-di-tert-butyl-P-Benzoquinone were detected in secretion of eight-week seedling.Though the content is in very low level,it is a breakthrough for the research of the Haloxlon root's secretion. (3)In the study of Cistanche seeds germination,the treatment of DMBQ together with CTK can promote the germination rate of the peeled Cistanche.seeds.And when different CTK was added into the culture that has DMBQ and GA3,the germination rate of Cistanche seeds was further improved.
