Koelreuteria bipinnata var. integrifoliola‘Jinyan'is a natural yellow mutant of K. bipinnata var. integrifoliola with higher ornamental value. In order to study the photosynthetic characteristics of K. bipinnata var. integrifoliola‘Jinyan',the pigment content,growth,diurnal variation of photosynthesis and light response curves of ‘Jinyan'and the wild type were determined with photosynthesis system. The results showed that the contents of chlorophyll a,chlorophyll b,total chlorophyll and carotenoids of ‘Jiny...
decreased,thereby affecting‘Jinyan’leaf coloration and growth,leading to the lower photosynthetic rate.自然界存在许多叶色突变现象,这些叶色突变体成为园艺观赏新品种选育的重要材料来源,也是植物光合作用机制研究的优良材料[1]。通常情况下叶色突变会影响植株光合?
