摘要
研究了低温弱光条件对2个辣椒品种光合色素含量的影响,结果表明:在亚适温弱光(100μmol.m2.s-1,23℃/10℃)条件下,辣椒叶片的叶绿素a、b含量增加,叶绿素a/b降低,随着温度的降低,光照的减弱,叶绿素a、b含量逐渐降低,叶绿素a/b有上升趋势,低温弱光处理后,辣椒叶片类胡萝卜素含量降低。
This research was about the effeceion of low temperate and weak light on two hot pepper varietis. The results were as follows：in the situation of 100^-2μmol·m^-2·s^-1 ,23℃/10℃ ,the concentration of chlorophyl-a and chlorophy-b in hot pepper leaves increased, while the ratio of chlorophyl-a/chlorophy-b reduced;according to the reduction of temperature and light the concentration of chlorophyl-a and chlorophy-b went down, while the ratio of chlorophyl-a/chlorophy-b went up;after the treatment of low temperature and weak light,concentration of carotenoids reduced in hot pepper leaves.
