不同类型小麦旗叶距与旗叶伸出长度及幼穗长度的相关性分析

Correlation Analysis between the Space of Flag Leaf and the Reached Extent of Flag Leaf as well as the Length of Young Inflorescences in Different Ecotype of Wheat

试验表明,小麦旗叶距与旗叶伸出长度及幼穗长度之间存在着极显著的同伸关系。其中旗叶距与旗叶伸出长度之间具有极显著正相关,小麦幼穗长度与旗叶距之间呈极显著指数相关,而小麦幼穗长度与旗叶伸出长度之间亦呈极显著正相关。同时,不同生态类型小麦的这些同伸关系也具有明显的不同。硬质小麦9812-2-1品系,当旗叶距为0时,旗叶伸出长度为28.04 cm,幼穗长度对旗叶距的回归方程为Y9812-2-1=3.943 6 e0.082 2x,-10.2≤x≤7.2;而软质小麦96118-42品系旗叶距为0时,旗叶伸出长度为17.93 cm,幼穗长度对旗叶距的回归方程为Y96118-42=3.111 3 e0.087 5x,-6.43≤x≤8.00。

Extremely significant correlation was observed among the space of flag leaf and the reached extent of flag leaf as well as the length of young inflorescences in wheat. Much significant correlation existed between the space of flag leaf and the reached extent of flag leaf, significant expofiential correlation were observed between the length of young inflorescences and the reached extent of flag leaf as well as the reached extent of flag leaf. Much difference was observed on the correlation between wheat of different ecotype. When the space of flag leaf was zero cm, the reached extent of flag leaf was 28.04 cm, the regression equation of the length of young inflorescences to the space of tlag leaf was Y9812-2-1=3.113e^0.0822x,-10.2≤x≤7.2 with regard to hard wheat line 9812-2-1, while it was different concerning soft wheat line 96118-42, when the space of flag leaf was zero cm, the reached extent of flag leaf was 19.93 cm, the regression equation of the length of young inflorescences to the space of flag leaf was Y96118-42=3.1113e^0.0875x,-6.43≤x≤8.00.
