大豆花芽分化和物候期的机理模型
Mechanism model for flower bud differentiation and phenophase of soybean
摘要
Abstract
A mechanism pattern was systematically established to predict flower bud differentiation and phe-nophase of soybean by using the principle of crop physiological development time constancy. Specific Bate function was applied in the model to present the thermal effect. Four genetic parameters as temperature sensitivity, photope-riod sensitivity, intrinsic earliness and filling fraction, were used to distinguish the difference in varieties. Result tested in different plant regions included flower bud differentiation (including perianth, pistil and stamens primor-dia, ovule and pollen differentiation or formation) , and phenophase (including flower primodium differentiation period, pistil and stamen primodium differentiation period, ovule and pollen formation period, seedling, blooming, podding, seed filling, and ripening. It suggested that the analogy model of soybean development stages was predictable with the most absolute errors of analogy between 0 and 4d. The root mean square error (RMSE) of the model was less than 3d.关键词
