- 摘要:
- 以1年生盆栽‘寒富’苹果及其亲本系品种（‘东光’和‘富士’）为试材，通过气体交换等方法对‘寒富’及其亲本系品种光合特性进行了研究，分析了光合速率变化规律及叶绿素含量、比叶重和叶面积对光合速率的影响。结果表明：‘寒富’与亲本系品种的光合能力、羧化效率（CE）、表观量子效率（AQY）、CO2补偿点，CO2饱和点、饱和光强、补偿光强等光合参数有差异；‘东光’对低浓度的CO2、强光和弱光的利用率较高，‘富士’对高浓度的CO2利用率较高，‘寒富’处于二者之间；成熟叶片的叶面积，比叶重和叶绿素含量与Pn之间存在相关性；亲本系品种有较高的Fv/Fm，而‘寒富’苹果具有较高的光合性能指数。
- Abstract:
- Taking one-yearold ‘Hanfu’ apple and its parents’ variety of ‘Dongguang’ and ‘Fuji’ as test materials,the photosynthetic characteristics were studied by gas exchange method,the changing of Pn and the effect of leaf area,SLW and chlorophyll content on Pn were analyzed.The results showed that there were differences among photosynthetic capacity,carboxylation efficiency (CE),apparent quantum yield (AQY),CO2 compensation points,CO2 saturation points,light compensation points,light saturation points among ‘Hanfu’,‘Dongguang’ and ‘Fuji’.‘Dongguang’ had higher using efficiency to low concentration CO2,low intensity illumination and high intensity illumination,‘Fuji’ had higher using efficiency to high concentration CO2；there were relativity between Pn and leaf area,SLW and chlorophyll content in mature leaves.Fv/Fm of ‘Dongguang’ and ‘Fuji’ were higher than that of ‘Hanfu’.PI of ‘Hanfu’ was higher than that of ‘Dongguang’ and ‘Fuji’.
