| Abstract: |
| The content and ratio of pigment, specific leaf area and photosynthesis efficiencies of 17 corn inbred lines were examined during late periods of growth and development.The results were as follow: 1. The process of pigment decreasing was slowly at first and then quickly, the chla/b and car/chl (Carotenoid/Chlorophyll) were relatively steady and arrived high value in flowering and dough stage respectively. 2. The content of chloropyll and specific leaf area were markedly different but chla/b and car/chl were not different among 17 inbred lines; 3. The content of chlorophyll and photosynthetic rate was positive correlated but car/chl was negative one. The 17 inbred lines were divided into 5 kinds of types by photosynthetic rate and content of chlorophyll. The relationship between feature of inbred lines in high photosynthesis and pigment was discussed in this paper. |
