研究了不同比重溶液分级的棉籽理化特性和出苗情况,用软X—射线鉴定了棉籽饱满度。结果表明:>1.00比重级的棉籽饱满度达80％以上。不同比重级棉籽的子指、仁指、密度、粗蛋白、粗脂肪等理化特性和棉籽发芽率、发芽指数等性状均随比重级增大而增大,而种子浸出液的电导率,则随比重级增大而显著减小。比重法分级棉籽,方法简便可行,可显著提高种用品质。
The physicochemical properties and emergence of cottonseed with various grading solutions were studied, and cottonseed fullness was identified by soft X-ray. The results showed that:> 1.00 gravity grade cottonseed fullness of more than 80%. Physiological characteristics such as finger, kernel, density, crude protein and crude fat of different specific grades of cottonseed, germination rate and germination index increased with the increase of specific gravity, while the conductivity of seed leachate increased with specific gravity Increases significantly and decreases significantly. Gravimetric grading cottonseed method is simple and feasible, can significantly improve the quality of planting.
