Results showed that the elongation of mesocotyl and internode of coleoptile played important roles in the seedling emergence of the weedy rice from northern China.

研究结果表明，在中国北方发现的部分杂草稻具有较强的中胚轴伸长特性和芽鞘节间伸长特性。

At tillering stage, spraying GA solution to the dwarf mutant could promote the elongation of the first and the second internode, but no significant effect on the length of the third internode.

喷洒法的结果也表明，在分蘖期，外源GA主要是促进基部第一、第二节间伸长，而第三节间及叶片则无显著增长。
