Low Temperature Effects on Growth and Physiological Traits of Chinese Cabbage Seedlings

doi:10.11924/j.issn.1000-6850.casb15030062

Abstract

Abstract: In this paper, the different Chinese cabbage genotypes were compared to study the response to chilling damages. The results may provide some evidences for breeding cabbage with low temperature tolerance in Heilongjiang Province. Chinese cabbage seedlings at three-leaf stage were treated with low temperature in climate chamber for 3 days. The physiological traits and biological yield were measured. In low temperature condition, the biological yield and chlorophyll content of the six varieties decreased. In addition, except ‘Xincuo4’, the soluble protein content of the other five Chinese cabbage varieties was higher than that of control. Except‘KB91-12’, the POD activity of the other five varieties under low temperature treatment was higher than that of control. Considering the cold resistant ability of the cabbage varieties,‘New Beijing 3’was the best. Thus‘New Beijing 3’can be used as one of cold resistance varieties in Heilongjiang Province.
