Chlorophyll content and photosynthetic characteristics of pepper inbred lines.

This study aimed to investigate chlorophyll content and photosynthetic characteristics of 17 pepper inbred lines which were selected independently. The results showed that chlorophyll contents significantly varied among different inbred lines. To be specific,chlorophyll content of No. 68 inbred line was significantly higher than that of other 14 inbred lines; chlorophyll content of No. 55 inbred line was significantly lower than that of other 15 inbred lines. The chlorophyll content of various inbred lines showed a decreasing order of No. 68 > No. 47 > No. 66 > No. 62 > No. 63 > No. 60 > No. 61 > No. 64 > No. 56 > No. 67 > No. 65 > No. 48 > No. 59 > No. 58 > No. 57 > No. 69 > No. 55; the photosynthetic rate of various inbred lines showed a decreasing order of No. 68 > No. 57 > No. 60 > No. 48 > No. 58 > No. 47 > No. 62 > No. 63 > No. 64 > No. 65; the maximum photosynthetic rate of No. 65 inbred line was significantly lower than other seven inbred lines,while no significant difference was observed among other nine inbred lines.
