Difference of parasitic form of Cynomorium songaricum and Cistanche deserticola
摘要
Abstract
Cistanche deserticola and Cynomorium songaricum are important tonic herbs of traditional Chinese medicine, but currently their wild resource is in danger of drying up in China because of excavation excessively or incorrectly meth-od. Cistanche deserticola is the endangered plant and Cynomorium songaricum is a rare vulnerable plant of extinction in China. The study on the parasitic forms and characters of them can promote the cultivation of them, at the same time, protect the wild medicinal herbs resource, and it has the important ecological significance on the adapted mechanism of parasitic plants to desert environment. We compared the parasitic forms of C. songaricum and Cistanche deserticola in their host plants respectively through morphology observation and routine paraffin section. The results were as follow:( 1) The vegetative propagation buds of Cynomorium songaricum grew on the root of host plant one by one and the para-sitic form was Non-End parasitic. The haustorium of C. songaricum invaded into phloem and partial part of xylem of host plant , but most areas of phloem and xylem were not been occupied by haustoria, namely some nutrients of host were“in-terception” by C. songaricum on the process of transportation. ( 2) Cistanche deserticola grew new buds in the base of fleshy stem, the parasitic form was End parasitic. The haustorium of C. deserticola invaded into all the xylem and phloem of host plant. After been parasitized by Cynomorium songaricum, the root of its host plant could grow continuely and have the regularly function. After been parasitized by Cistanche deserticola, the root of host plant losed normally function, and became a“Transport channel” to supply nutrition for C. deserticola.关键词
