摘　　要：通过研究赤霉素(GA)、玉米核苷酸(ZR)、吲哚乙酸(IAA)、脱落酸(ABA)4种激素和过氧化物酶(POD)、多酚氧化酶(PPO)、超氧化物歧化酶(SOD)、过氧化氢酶(CAT)4种酶以及蛋白质在杂种马褂木不同个体中的变化规律,探索可用于杂种马褂木早期选择的生理生化指标,结果表明,ZR和IAA可以作为杂种马褂木生长量早期预测的首选指标,GA可作为辅助指标,参试酶和蛋白质在本研究中呈不规律变化。By studying the changing rules of four kinds of hormones which include GA,ZR,IAA,ABA,proteins and four kinds of enzymes involving POD,PPO,SOD,CAT,in different plants of Liriodendron hybrid,the physiological and biochemical indicators of early selection of Liriodendron hybrids were explored.The results showed that,ZR and IAA can be used as a preferred indicator of early prediction of growth indices of Liriodendron hybrid,and GA as a supplementary indicator.Tested enzymes and proteins in this experiment had irregular changes.
