赤霉素对三个黑稻品种生长的作用

Effect of Gibberellin on the Growth of Three Cultural Black Rice

用 3个浓度的赤霉素对 3个品种的黑稻 (黑丰糯 ,黑粳 ,黑优粘 )的幼苗进行处理 ,结果表明 ,黑丰糯对GA的反应较为敏感 ,其生长的增加量与GA的浓度有近乎线性的关系 ,而黑粳及黑优粘对赤霉素处理的反应不明显。

Three of black rice (Hei Feng_nuo, Hanzhong Heijing, Hei You_zhan) were treated with three different concentration of gibberellin solutions.It was found that Hei Feng_nuo was more sensitive to GA, and the growth rate was nearly in linear relationship with the concentration of GA, but Hei Jing and Hei You_zhan were not sensitioe to GA.
