棉花种子活力与幼苗生长势相关性研究

Correlation Analysis of Cotton Seed Vigor and Seedling Potential

对不同棉花品种进行发芽试验表明 ,棉花的播种品质与发芽品质和幼苗生长势密切相关 ,任何单一指标均不能正确反映棉种活力品质。实际检验时 ,应综合考虑活力指数和幼苗干重等指标 。

The germination test of different cotton varieties was done,the results showed that the seeding quality of cotton had high correlativity with germination quality and seedling potential,anyone of this inderes couldnt correctly represent seed vigor.It couldnt pladge the accuracy of assessment unless you compositely consider at least vigor index and seedling dry weight in actual examination
