摘要:
以梧桐（Firmiana simplex(L.)W.F.Wight）种子为试材，研究不同浓度赤霉素、水杨酸、α-萘乙酸以及层积处理对梧桐种子萌发率的影响，并研究不同浓度赤霉素和α-萘乙酸2种激素对梧桐幼苗生长的影响。结果表明：浓度为0.075 g/L的水杨酸处理和层积处理，能够显著提高梧桐种子的萌发率；0.050、0.075 g/L的α-萘乙酸能够分别显著促进梧桐幼苗主根以及主茎的生长，而赤霉素和α-萘乙酸对梧桐叶片的生长都具有抑制作用，浓度越高，叶片越小。
Abstract:
Taking Firmiana simplex(L.)W.F.Wight as material，the effect of different concentrations of GA3(Gibberellin A3）,SA(Salicylic acid）,NAA（1-Naphthalene acetic acid）and stratification on germination of seeds were studied firstly，then the influence of GA3 and NAA on growth of seedlings was analyzed.The results showed that the germination percentage could be raised by the concentration of 0.075 g/L SA and stratification markedly.It had been indicated by the experiment that the growth of the main root and main stem could be promoted by the concentration of 0.050 g/L and 0.075 g/L NAA，respectively.However，the leaf length and leaf width were decreased significantly by the treatment of GA3 and NAA.
