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)。

关 键 词:玉米  单叶面积  估测  地上生物量

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.
Keywords:maize  individual  leaf  area  estimating  biomass  on  ground
