Abstract

The physiological indices ofChinese cabbage(Brasska chinensis L.) grown under different intercropping systems used for this study included total soluble protein content, soluble sugar content, reducing sugar content, nitrate content, and pigment concentration. Ihe objective of the present study is todiscover the physiological level changes inChinese cabbage inintercropping systems. Ihe intercropping systems studied involved Chinese cabbage- garlic {Allium sativum L.) (CG), and Chinese cabbage-lettuce [Lactuca saliva J,.) (CL). Chinese cabbage monoculture served as control (CK). Overall, liigher mean soluble protein content and nitrate content were found in Chinese cabbage grown inthe intercropping systems than those inCK. Significantly higher chlorophyll a content was found in cabbages from CL than CK during the latter halfofthe growing season, No significant difference insoluble sugar concentrations was found inCG and CL, as comparedwith CK. Reducing sugar content varied over the growing period ofthe Chinese cabbage in CG and CL. These results suggest that Chinese cabbage intercropped with noncrucifer plants increase the plant nutrient content.
