【摘要】 本文提出,在玉米籽粒生长发育过程中,于物质累积呈逻辑斯蒂模型。模型的参数主要受生育期平均气温制约。在成熟期,籽粒干重不仅与籽粒发育期间的平均气温有关,还与籽粒发育所经历的天数有关。更多还原

【Abstract】 This paper suggests that the accumulation of stored substance during the growth and development of the corn seeds is in the form of Logistic model. The parameters of the model are mainly controlled by average air temperature. Besides.the dry weight of mature seeds Q is also controlled by the duration of development measured in number of days, D, of the corn seeds.更多还原
