摘　　要：研究了低温和高温下影响不同品种大白菜叶绿素a、叶绿素b、和叶绿素(a+b)积累差异的因素,分析了大白菜对温度胁迫下叶绿素的适应能力。结果表明,15种大白菜在0℃前后,叶绿素a、叶绿素b、叶绿素(a+b)含量差异不同,与品种有关。15种大白菜中有11个品种在温度下降后叶绿素a含量减少,所有品种的叶绿素b在低温条件下都有所下降。10种大白菜的叶绿素(a+b)含量在0℃后下降,5种大白菜的叶绿素(a+b)含量在0℃后上升。5个品种大白菜在高温处理下,叶绿素a、叶绿素b、叶绿素(a+b)含量变化趋势不一致。该试验为狮子头大白菜的栽培、品种创制提供参考依据。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 chlorophyll under temperature stress.The contents of chlorophyll a,chlorophyll b and chlorophyll(a+b)of 15 kinds of Chinese cabbage were different 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 decreased 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 after 0℃.The contents of chlorophyll a,chlorophyll b and chlorophyll(a+b)in 5 varieties of Chinese cabbage were different under high temperature treatment.This experiment provides reference for the cultivation and variety creation of“lion head”Chinese cabbage.
