Histoanatomical observation on the process of Taxillus chinensis infecting Camellia semiserrata
Process of Taxillus chinensis invading into Camellia semiserrata was observed at the level of histological anatomy by paraffin section and microscopic observation.The results showed that there were two invasion forms of T.chinensis,one way to invade is through seeds,and the other way is through twining root.T.chinensis seeds invade into the host mainly by self-secreted colloidal substances flowing between host cells and wrapping them,and then degrading the host cells to form a number of tiny sacs,at the same time,the host will form callus to gradually wrap the parasitical seeds into the body.Twining roots invaded into the host by spreading the host cortex through the"expansion screw structure",the sucker tissue continuously secretes colloidal substances into the host tissue and degrades the host cells,and the sucker gradually grows into the host body.This study has certain reference significance for further revealing the pathogenic mechanism of T.chinensis.
