Abstract
|
|
|
|
M. incognita are plant-parasite nematode that cause severe damage to the crops.P.lilacinus are renowned for inhibitation of development of M.incognita’s egg. We make a study for enzymatic examining the cause closely that P.liacinus suppress development of M.incognita’s egg by parasiting. The research result is explained the place below. l. The egg that is exposed to co-enzymes which are cultured in the broth culture starts to change the membrane of egg from 3days. And in 10days, that membrane completely disappear. These are observed through light microscope. Therefore, we know that M.incongnita are controlled by extracellular lytic enzymes taat are produced by P. lilacinus. 2. Through scanning electron microscope, we can find that the egg that is attacked by P.ilacinus loses it’s membrane gradually, and that loss of the membrane causes transform, which suppresses the development of egg.
