GA(subscript 1+4) distribution in microspore mother cells, uninucleate and binucleate pollen, especially in nucleus, gradually increased with the anther development. Moreover, some GA(subscript 1+4) distributed in sperms.

短日照条件下花药可育，花粉母细胞、单核花粉和二核花粉内GA(下标 1+4)的分布数量逐浙增多，以细胞核最为明显；成熟花粉的精细胞内也有一定数量的GA(下标 1+4)分布。

Physiologically, our model estimated 2.6 days to reach the single ridge stage, 5.6d to the double ridge stage, 11.3d to the stamen and pistil initiation stage, 13.1d to the anther separation stage, 15.3d to the pollen mother cells stage and 18.2d to the tetrad stage. Phenologically, estimations were 13.1d to reach the jointing stage, 28.7d to the heading stage, 32.8d to the grain filling stage and 51.5d to the maturity stage. PDT was consequently used as a unified scale for measuring developmental progress of different cultivars under different climates and cultural practices.

经测算，各大麦品种到达单棱期、二棱期、雌雄蕊分化期、药隔形成期、雌蕊柱头二裂分叉期、雌蕊柱头毛状突起期等顶端发育阶段的生理发育时间分别为2.6、5.6、11.3、13.1、15.3、18.2、28.7d，到达出苗期、拔节期、抽穗期、灌浆期和成熟期等主要物候期的生理发育时间为0、13.1、28.7、32.8、51.5d，形成了不同大麦品种在不同气候和栽培条件下统一的衡量发育的定量尺度。
