| 摘 要： | 以绿叶桃和绿叶李品种为对照, 研究了田间条件下不同季节红叶桃、紫叶李的光合特性。结果表明: (1) 红叶桃、紫叶李的净光合速率( Pn) 在春、夏季低于绿叶品种, 而秋季较为接近, 彩叶品种与绿叶品种间的差异随季节进程不断减小; ( 2) 红叶桃、紫叶李的表观量子效率(AQY) 和羧化效率(CE) 在春、夏季均显著低于对应的绿叶品种, 秋季时红叶桃和紫叶李的表观量子效率高于绿叶品种, 羧化效率与绿叶品种接近; (3) 红叶桃、紫叶李的光补偿点(LCP) 在春季和夏季显著高于绿叶品种, 秋季时则显著低于绿叶品种, 光饱和点(LSP) 始终高于或接近于绿叶品种; (4) 红叶桃、紫叶李的光合色素含量与绿叶品种差异较小, 但其花色素苷含量始终比绿叶品种高许多; (5) 红叶桃、紫叶李光呼吸(Rp)均低于绿叶桃和绿叶李。

| Abstract: | The photosynthetic characteristics of red-leaf peach and purple-leaf plum were studied with the green-leaf peach and green-leaf plum varieties as control in field in different seasons. The result showed that: (1) The Pn of red-leaf peach and purple-leaf plum was significantly lower than that of green-leaf peach and green-leaf plum in spring and summer without significant difference in autumn, and the difference between two species was gradually reduced from spring to autumn; (2) Apparent quantum yield (AQY) and carboxylation efficiency (CE) of red-leaf peach and purple-leaf plum were significantly lower than that of green-leaf peach and green-leaf plum in spring and summer. The AQY of red-leaf peach and purple-leaf plum was higher than that of green-leaf cultivars, and CE was similar between two species in autumn.;(3) Light compensation point (LCP) of red-leaf peach and purple-leaf plum was significantly higher than that of green-leaf cultivars in spring and summer, but significantly lower than that in autumn. Light saturation point (LSP) of red-leaf peach and purple-leaf plum were always higher than that of green-leaf cultivars or similar to them; (4) The content of photosynthetic pigment was not significantly different between the red-leaf peach and green-leaf peach, but the content of anthocyanin of the red-leaf peach and the purple-leaf plum was always higher than that in green-leaf cultivars;(5) Photo respiration (Rp) of red-leaf peach and purple-leaf plum was significantly lower than opposite green-leaf cultivars as control. |
