| 摘 要： | 对金皇后和敖汉苜蓿两种苜蓿的株高、草产量及净光合速率等因素进行相关分析,结果表明：不同生长年限敖汉苜蓿的植株高度高于金皇后,但产草量低于金皇后；有效光辐射极显著影响两种苜蓿的净光合速率。空气湿度、空气温度和胞间二氧化碳浓度与净光合速率呈显著负相关。

| Abstract: | The correlation of plant height, yield,net photosynthesis (Pn) and other factors of Golden Empress and Aohan were analyzed.The results showed that the plant height of Aohan was higher than that of Golden Empress. However, its yield was lower thanthat of Golden Empress. The PAR could influence net Pn of both varieties significantly. The air humidity, air temperatureand intercellular carbon dioxide concentration were was negatively correlated with netPn. |
