| 摘 要： | 采用室内培养方法，研究了丸粒化处理对不同品种棉花种子萌发期抗寒性及生理特性的影响。结果表明：⑴胚根鲜重及简化活力指数提高；⑵胚根中可溶性蛋白质含量、可溶性糖含量明显增加；⑶胚根中丙二醛含量、相对电导率显著降低。试验结果表明，与包衣处理对比，棉花种子丸粒化处理能明显加速种子内的营养物质转化，促进幼苗生长，增强抗寒性。

| Abstract: | Effects of different varieties of cotton seed pelletizing on the cold-risistance and physiological characteristics were studied in laboratory. As a result,⑴ The fresh weight of radicles and simplified vigor index improved;⑵ Contents of the soluble protein and the soluble sugar in the cotto radicles improved significantly;⑶ The MDA content and the relative electric conductivity decreased remarkablly compared with coated control. It was concluded that cotton seeds pelletizing may effectively promote the transformation of nutrient substance in cotton seeds, seedling growth and increase the cold resistance. |
