The content of chlorophylls (Chl) (+), total carotenoids (+), and the pigment ratios of Chl / and Chls to carotenoids (+)/(+) of green leaves of five C plants were determined and compared to those of C plants. The C plants were: Pacific and Chinese silvergrass ( and ), sugar cane () as well as feed and sugar maize (). The three C plants were beech, ginkgo, and oak. C plants possess higher values for the ratio Chl / (3.4-4.5) as compared to the C plants (2.6-3.3). Sugar maize had the highest values for Chl / (4.04-4.70) and exceptionally high contents of total carotenoids and consequently lower values for the ratio of ()/() (mean: 3.75 ± 0.6). During autumnal senescence also C plants showed a faster decline of Chl as compared to Chl yielding high values for Chl / of 6 to 8. Chlorophylls declined faster than carotenoids yielding low ()/() values below 1.0.
测定了5种C4植物绿叶中叶绿素（Chl）（+）、总类胡萝卜素（+）的含量以及Chl / 和Chls与类胡萝卜素（+）/（+）的色素比率，并与C3植物进行了比较。C4植物为：太平洋银草和中国银草（和）、甘蔗（）以及饲料玉米和甜玉米（）。三种C3植物为山毛榉、银杏和橡树。与C3植物（2.6 - 3.3）相比，C4植物的Chl / 比率值更高（3.4 - 4.5）。甜玉米的Chl / 比率值最高（4.04 - 4.70），总类胡萝卜素含量异常高，因此（）/（）比率值较低（平均值：3.75 ± 0.6）。在秋季衰老过程中，与叶绿素b相比，C3植物的叶绿素a也显示出更快的下降，导致Chl / 值高达6至8。叶绿素的下降速度比类胡萝卜素快，导致（）/（）值低于1.0。
