| 摘 要： | 在田间条件下,采用LI-6400便携式光合测定系统,对制汁葡萄品种卡托巴、康可和黄金玫瑰的主要光合指标进行测定,并调查其生物学特性。结果表明:制汁葡萄光补偿点在23.9~42.2μmol.m-2.s-1;光饱和点在1 575.0~1 642.9μmol.m-2.s-1;CO2补偿点在65.1~74.3μmol/mol;CO2饱和点在897.5~1 061.7μmol/mol;表观量子效率在0.036~0.044μmol/mol;羧化效率在0.067~0.095 mol.m-2.s-1。3个制汁葡萄品种中,黄金玫瑰对强光和弱光的利用能力均较强,RuBP最大再生速率显著高于康可和卡托巴,并且具有较强的耐旱力和较高的产量,表现出了较强的光合能力和适应性。

| Abstract: | The main photosynthetic parameters of Catawba,Concord and Golden Muscat were studied with LI-6400 portable photosynthesis system under field condition,including observation of their biological characteristics.The results showed that light compensation point of juicing grapes was between 23.9 and 42.2 μmol·m-2·s-1;light saturation point was between 1 575.0 and 1 642.9 μmol·m-2·s-1;CO2 compensation point was between 65.1 and 74.3 μmol/mol;CO2 saturation point was between 897.5 and 1 061.7 μmol/mol;apparent quantum yield was between 0.036 and 0.044 mol/mol;carboxylation efficiency was between 0.067 and 0.095 mol·m-2·s-1.In the aspect of maximum regeneration rate of RuBP,Golden Muscat was remarkably higher than Catawba and Concord,besides,Golden Muscat had higher light utilization efficiency,drought tolerance and yield.Among the three juicing grapes,Golden Muscat shows higher photosynthetic capacity and stronger adaptation to the environment. |
