摘要
本试验以L1-L2-L3层倍性为2-4-4的同源四倍体玫瑰香嫩枝插条为试验材料,在全光照自动喷雾扦插条件下研究了其不定根发生的外部形态变化。结果表明,同源四倍体玫瑰香嫩枝扦插生根能力较原母株下降。在扦插第18d,其嫩枝扦插不定根发生率为51.4%,平均每个插条的不定根数量为4.27条,不定根总长度仅为2.41cm,上述各项指标均显著低于其二倍体母株。
The morphologic characteristics of adventitious root development in softwood cuttings of autotetraploid grape Muscat Hamburg, the polity of which in L1-L2-L3 layer 2-4-4, were tested in the condition of auto-spraying fulMight-fog. The results showed that rooting capability in softwood cuttings of Autotetraploid Grape Muscat Hamburg was declined compared with the mother plant. The rooting rate （51.4%）, root number per softwood cutting （4.27） and root length per softwood cutting （2.41cm） were significant lower than that of the control respectively.
