영문 초록

Studies were performed to investigate the difference in photosynthesis and related characteristics according to different plant types;growth stage and leaf position in sesame. Three different plant-type varieties were selected from Korean recommended sesame cultivars and used as materials. Average photosynthesis during whole growing period was 1.64 CO₂ ㎎/d㎡/hr. Few-branched type variety “Kwangsankkae” showed 2.006 CO₂ ㎎/d㎡/hr which was the highest one among three plant types. Upper part leaves at maturing stage showed the highest photosynthesis and the next followed with the order of middle part leaves at maturing stage;and leaves of seedling stage. Average chlorophyll content of single leaf through the whole growing period was 3.31 ㎎ per 100㎠ of leaf area(LA) and was highest in few-branched type variety “Kwangsankkae”. Upper part leaves at maturing stage showed the highest chlorophyll content of 4.39 ㎎/100 LA. Average area of single leaf through the whole growing period was 16.5㎠. Middle part leaves at maturing stage in branched type variety “Hansumkkae” showed the highest chlorophyll content among plant types and growing stages. Average specific leaf weight(SLW) during the growing period was 0.0033. The upper part leaves at maturing stage in branched type variety “Hansumkkae” revealed the heaviest one. Average specific leaf area(SLA) during whole growing period was 275 and was highest in the leaves of non-branohed type variety “Danbaeckkae” at seedling stage. Dry weight ratio;SLW and chlorophyll content were positively associated with photosynthesis;while leaf area;fresh and dry leaf weight were negatively correlated with photosynthesis.
