摘要
对从江苏泰兴引进甘肃的泰兴大佛指、七星果、大佛手、圆玲6号、大马玲等5个银杏优良品种的主要光合生理指标、光合日变化进行了比较研究,以净光合速率、光能利用效率、水分利用效率等参数对各品种进行了综合分析。试验结果表明:引进的5个品种(系)中,圆玲6号对强光和弱光利用能力均高,有较强的光合能力,非常适宜于徽县各种立地条件下栽植;大佛手对强光利用能力高而对弱光利用能力较差,抗旱能力最强,适宜栽植在山坡上光照条件较好的地方。在水分利用方面,除了大马玲外其余几个品种均高于当地品种。
Comparative study was conducted on main photosynthetic physiological indexes and diurnal variation of photosynthesis of 5 fine varieties of Ginkgo biloba,which were introduced from Taixing of Jiangsu（Taixing Dafuzhi,Qixingguo,Dafushou,Yuanling 6 and Damaling）.Based on parameters of photosynthetic rate,light-energy utilization efficiency and water use efficiency,comprehensive analysis was conducted on varieties of Ginkgo biloba.The results showed： Yuanling 6 of 5 fine varieties of Ginkgo biloba had high ability to use strong light ＆ weak light and also had high photosynthetic ability,so Yuanling 6 was very suitable for planting in all kinds of site condition in Huixian county;Dafushou had high ability to use strong light and had low ability to use weak light,drought-resistant of Dafushou was effective and it was suitable for planting in hillside with good light condition.5 varieties of Ginkgo biloba all had higher ability to use water than local varieties except Damaling.
