| Abstract: | The M4 sweet pepper after space induction was used to study the mechanism of space mutagenesis. The changes in photosynthetic indexes, pigment content and ultrastructure of chloroplast in sweet pepper were studied. The results indicated that the contents of leaf chlorophyll a, b, the ratio of a and b, total chlorophyll and carotenoid content decreased in SP06-31, a mutant compared to those of the control L06-30, The contents of chlorophyll a and total chlorophyll were significantly difference from those of control. The change of photosyn the tic rate of both L06 -30 and SP06 -31showed a one peak pattern, and the change of transpiration rate showed one peak pattern, too. The change of intercellular CO2 concentration showed a funnel like trend and that of stomatal conductance was followed by a one peak trend. The mesophyll cells were broken, the number of starch grains in chloroplast was ncreased, intercellular space was enlarged, and parts of chloroplast grana lamella were ambiguity in the mutant. |
