向日葵耐盐碱材料筛选的新途径

The Study on Growth and Development of Winter Wheat Grown in Changchun

摘要:

向日葵是一种具有耐瘠薄、适应性强等特性的油料作物，我省乃至全国的广大农民都喜欢把它种植在贫瘠土地上，特别是种植在含盐量较高的盐碱土地上。因此，筛选出耐盐碱的向日葵品种，可以大幅度地增加种植面积，提高产量，产生良好的经济效益。本文试验结果表明:通过增加液体含盐量浓度(近海水盐分构成)供给种子萌动发芽，来测定对不同向日葵种子发芽率的影响，可以用于大量筛选向日葵耐盐碱品种及自交系。

Abstract:

Six varieties of winter wheat were planted in ChangchunWinter wheat was sowed in the middle of September and was harvested at the end of June to the begining of July. The number of total stems of winter wheat reached the highest before overwintering stage and declined after overwinter- ing. The coefficients of correlation of the number of stems in turngreen stage and heading stagenumber of spike with plot yield were positive significantly.
