This experiment studied the factors affecting the difference of chlorophyll a,chlorophyll b,and chlorophyll(a+b)accumulation in different varieties of Chinese cabbage under low temperature and high temperature,and analyzed the adaptability of Chinese cabbage to chloro-phyll under temperature stress.The contents of chlorophyll a,chlorophyll b and chlorophyll(a+b)of 15 kinds of Chinese cabbage were differ-ent under the condition of 0℃,which was related to the variety.The content of chlorophyll a in 11 of the 15 varieties of Chinese cabbage de-creased after the temperature dropped,and the content of chlorophyll b in all varieties decreased at low temperature.The content of chlorophyll(a+b)in 10 kinds of Chinese cabbage decreased after 0℃,and the content of chlorophyll(a+b)in 5 kinds of Chinese cabbage increased af-ter 0℃.The contents of chlorophyll a,chlorophyll b and chlorophyll(a+b)in 5 varieties of Chinese cabbage were different under high tem-perature treatment.This experiment provides reference for the cultivation and variety creation of"lion head"Chinese cabbage.
