| 摘 要： | 研究苗期（４叶期）、拔节期、灌浆期“白马牙”玉米（ＺｅａｍａｙＬ．）单叶面积与单株地上生物量（鲜重或干重）的回归方程。结果表明：按从上至下的叶序，苗期第２叶、拔节期第５叶和灌浆期第４叶的叶面积分别与该期的单株地上生物量呈最显著的正相关，可分别用来快速估测该生育期的单株地上生物量（鲜重或干重）。

| Abstract: | In seedling stage (4 leaf stage),jointing stage,and milk stage the linear relationship between individual leaf area and total plant biomass (fresh weight or dry weight)on ground of white Horse Tooth maize (Zea may L)were studied.The leaf area of the second leaf (leaves were numbered from the top of the plant) in seedling stage,fifth leaf in jointing,and fourth leaf in milk stage had the most significant positive correlation respectively,with total plant biomass on ground in the same stage ,the regression equation could be used to estimate rapidly the total plant biomass (fresh weight or dry weight )on ground in the stage respectively. |
