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

All of these recessive mutations, which are considered to be null alleles, exhibit defects in internodeelongation.
