小麦种子质量控制影响因素研究

摘要

Using the wheat seeds of Lianmai 2 and Yannong 19 as test materials,we investigated the influencing factors of the wheat seed quality and discussed their quality control technology. The results showed that the use of breeders and pure nitrogen 240 kg/hm2 and the removal of impurity on the milkstage were benefitial to the quality of seed breeding. The germination percentage and its decreasing amplitude after drying are in the significant negative correlation; the water content and the decreasing amplitude of the germination percentage after drying and storing are in the significant positive correlation.%以连麦2号和烟农19小麦种子为试验材料,考察了小麦种子质量控制的主要影响因素,探讨了小麦种子质量全程控制技术.结果显示,采用育种家种子、施用纯氮240 kg/hm2、乳熟期去杂等技术有利于小麦繁种质量,发芽率与其烘干后降幅呈显著负相关,含水量与其烘干后及贮藏后发芽率降幅都呈显著正相关.
