The effect of the changes of the endogenous hormone's contents ( aba and iaa) in hardwood cuttings of peach to rooting

桃硬枝插条内源激素（ABA、IAA）含量变化对生根的影响

One of the important reasons that the rooting percentage of hardwood cuttings was lower than softwood cuttings is its higher IAA concentration.

硬枝插穗体内IAA含量高于嫩枝插穗，也是硬枝扦插生根率低于嫩枝的主要原因之一。
