- 摘要:
- 以5个不同起源地的辣椒种质为试材,冬季在大棚内模拟低温弱光逆境,研究了低温弱光下不同起源地辣椒叶片叶绿素荧光参数的差异。结果表明:在相同的低温弱光逆境下,不同辣椒种质的叶绿素荧光参数差异较大;其中,起源于土耳其的‘20805’PS II最大光化学效率、通过PS II的电子传递速率ETR最大,而起源于印度的‘印度魔鬼椒’相对最小;由此可推测,低温弱光下5个不同辣椒种质中‘20805’具有较高光能利用率和潜在生物产量的生物基础。
- Abstract:
- Taking five different origin peppers as materials,under low temperature and poor light,the chlorophyll fluorescence parameters were studied.The results showed that in the same low temperature and poor light stress,the chlorophyll fluorescence parameters of different origin pepper varied widely.Among them,the PS II conversion efficiency of light energy and the apparent photosynthetic electron transport rat of ‘20805’ originated in Turkey were the best,‘India devil pepper’ originated in India was the worst.It could be speculated that under low temperature and poor light,‘20805’ had higher utilization rate of light energy and potential physiological and the biological basis of potential biological yield.
