| Abstract: | The relationship between characters of plant type in critical stage of effective tiller emergence and yield was studied in population of different yield with Shanyou 63 and 9516 as material. The results indicate that leaf angle and loose degree of N-n stage in high yield population are larger and leaf length is moderate, the leaf is thicker and chlorophyll content is high, leaf area increases slowly and LAI is small, and the dry matter of leaf sheath accumulates fast and leaf area per weight of leaf sheath is smaller. |
