以11种柑桔幼苗为试材，研究了其生长势（以树高为测定指标）与叶片内的过氧化物酶活性、GA1＋3＋4＋7和ABA含量的关系，结果表明：随着株高的增加，叶片过氧化物酶活性降低，GA1＋3＋4＋7含量、GA1＋3＋4＋7／ABA值上升，ABA含量有下降趋势，其中叶片过氧化物酶活性、GA1＋3＋＋4＋7／ABA值与株高呈显著相关。
Eleven kinds of citrus seedlings were used as experimental materials to study the relationship between the growth potential (measured by tree height) and peroxidase activity, GA1 + 3 + 4 + 7 and ABA content in leaves. The results showed that with the increase of plant height, The content of GA1 + 3 + 4 + 7 and GA1 + 3 + 4 + 7 / ABA increased while the content of ABA decreased. The leaf peroxidase activity and GA1 + 3 ++ 4 + 7 / ABA were significantly correlated with plant height.
