中籼籽粒形成期间气温与稻米垩白关系的研究

Studies on the relation of atmospheric temperature to chalk during kernel formation of middle Indica rice

本试验除用相关系数外,初次试用变异系数和回归系数分别统计分析了12个南方稻区代表性的中籼品种在不同播期下,气温与垩白率的关系,品种的稳定性和适应性,是有意义的.

Besides correlation coefficient, variation coefficient and regressioncoefficient were first used to statistic-analyse the relationship between the atmo-spheric temperature and chalk percentage, the stability and adaptability of 12representative varieties of middle Indica rice in the southern rice region underdifferent sowing time respectively in this study, It may be useful to qualitybreeding and variety ecologic division of rice.
