| 摘 要： | 为选育高光效的刺葡萄品种,以16份野生刺葡萄资源的枝条为接穗,高接于以SO4为基砧的6年生红地球葡萄植株上,以红地球葡萄为对照,对不同刺葡萄类型的光合特性进行研究。研究结果表明:不同类型的刺葡萄种质资源光合特性差异明显,浏阳刺葡萄雄株和白刺葡萄净光合速率最大;叶片中叶绿素含量与净光合速率密切相关,且对净光合速率影响最为显著是叶绿素b的含量;不同类型的刺葡萄资源其暗呼吸速率不同,芷江Co60辐射刺葡萄属低消耗型刺葡萄种质;净光合速率与蒸腾速率和胞间CO2浓度呈正相关,而与气孔导度无显著性相关。通过对光合特性进行综合评价,白刺葡萄属高光合效率型、高光能利用率型和高水分利用效率型;芷江Co60辐射刺葡萄属叶绿素a、b积累型,CO2高利用型和水分高利用型,低消耗型种质资源。

| Abstract: | To screen V. davidii Foex varieties with high photosynthetic efficiency,16 samples were grafted onto six-year-old red globe grape trees as the base stock of SO4,the red globe plants as the control,the net pho?tosynthetic rates of different varieties of top grafting V. davidii Foex were determined.The leaf chlorophyll content and net photo synthetic rates of V. davidii Foex varieties were closely related,and the chlorophyll b content had the most significant effects on the net photosynthetic rate of V. davidii Foex varieties.The intercellular CO2 con?centration and transpiration rate were the major fectors in the level of net photosynthetic rate in V. davidii Foex varieties.From the comprehensive assessment,two V. davidii Foёx germplasm resources were screened.V. davidii Foёx shuijing was a type of high photosynthesis efficiency,high light utilization and water use efficiency.V. Davi?dii Foёx Zhijiang Co60 was a type of low consumption.V. clone Foёx Liuyang♂ was a type of small blade,early bloom,and mesh surface. |
