| 摘 要： | 以本溪山樱(Cerasus sachalinensis Kom. ) 和大青叶(C. pseudocerasus G. Don. ) 为试材, 通过气体交换方法比较了在田间和盆栽方式下2 种樱桃的光合特性。结果表明, 田间植株的净光合速率( Pn) 、光合能力、羧化效率(CE) 、表观量子效率(AQY) 、RuBP最大再生速率等参数均高于盆栽植株。一天中田间植株的Pn、蒸腾速率( Tr) 及气孔导度(Gs) 基本高于盆栽植株, 而细胞间隙CO2浓度(Ci)基本低于盆栽植株。分析了导致田间和盆栽樱桃植株光合特性不同的可能原因。

| Abstract: | The photosynthetic characteristics of Cerasus sachalinensis Kom.and C.pseudocerasus G.Don.'Daqingye' grown in field and in pot were studied by gas exchange.The results showed that the net photosynthetic rate(Pn),photosynthetic capacity,carboxylation efficiency(CE),apparent quantum yield(AQY)and maximum regeneration rate of RuBP of cherry grown in field were higher than those grown in pot.Pn,transpiration(Tr)ratio and stomata conductance(Gs)of cherry grown in field were higher than those grown in pot,but the intercellular CO2 concentration(Ci)was lower than that in pot during daytime.The physiological mechanism in photosynthesis of cherry grown in field differed from the potted plants. |
