| 摘 要： | 以苋菜试管苗为材料,研究了光质、光周期、温度和pH等条件对苋菜光合色素、苋菜红色素以及花色素苷含量变化的影响.结果表明,温度(20±1)℃、pH 5.4、白光照射以及光照24 h·d-1均可促进叶绿素和类胡萝卜素的合成；在20～32℃范围内,温度对苋菜花色素苷累积影响不大；pH 5.4和5.8时,花色苷含量均较高；白光...

| Abstract: | The effects of different environmental factors,such as light quality,photoperiod,pH and temperature,were studied on the pigment accumulation of in vitro amaranth plantlets.The results showed that both the chlorophyll synthesis and carotenoid synthesis were increased at(20±1)℃,with pH 5.4,white light under 24 h·d-1.The content of anthocyanin was no significant difference at 20-32 ℃,but higher between pH 5.4 and 5.8,and higher through white light treatments,and higher and not significant difference between 12 and 18 h·d-1.The content of amaranth red pigment was higher at(20±1) ℃. |
