摘要: 对5个不同纬度来源的野生大豆(Glycine soja)、栽培大豆(Glycine mas)和半野生大豆进行同地移栽和分期播种实验表明,1年生野生大豆的拟种群的3类组元动态均符合Logistic增长规律,参数r与纬度呈正相关,参数K受环境饰变影响.拟种群动态拟合参数r与个体的生殖力呈正相关,证实植物拟种群动态具有重要的生态适应意义.

Abstract: Wild,half-wild and cultivated soybeans originated from different latitudes are transplanted to same area and sowed at different time.The results show that the metapopulation dynamics of three kinds of structural units of Glycine soja can all be simulated with logistic model,where parameter r is positively correlated with latitude, and K is affected by environmental modification.The simulation parameter r of metapopulation dynamics is positively correlated with the reproductive capacity of the plant,which substantiates that metapopulation dynamics of plant has an important significance of ecological adaptation.
