【摘要】 用田间出苗率与种子发芽率的比值对高粱出苗能力进行量化测算。结果表明，中国高粱及其衍生系的出苗力值远大于从中东地区和印度国际半干旱研究所引进的高粱，这与中国高粱顶主力强，外引高粱顶土力差，捉苗难的实际情况一致。相关分析表明，高粱出苗力与芽长和根茎长呈高度正相关，与根茎比值呈高度负相关。更多还原

【Abstract】 Sorghum bud emerging ability was quantitatively assessed. The value of emerging ability of materials of Chinese sources is much higher than that of exotic ones. It was proved that the sorghum emerging ability had highly positive correlation with hypocotyl length,and had negative correlation with the ratio of root to hypocotyl.更多还原
