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 g/L、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。

The effects of gibberellin, salicylic acid and α-naphthalene acetic acid with different concentrations on the germination rate of Sycamore seed were studied with the seeds of Firmiana simplex (L.) WFWight. The effects of different concentrations of Gibberella zeae Effects of Two Hormones - α and α - Naphthalene Acetic Acid on the Growth of Sycamore Seedlings. The results showed that treatment with salicylic acid at a concentration of 0.075 g / L could significantly increase the germination rate of Sycamore seedlings. Α-Naphthaleneacetic acid (0.050 g / L and 0.075 g / L) The main stems growth, while gibberellin and α-naphthalene acetic acid inhibited the growth of the leaves of Sycamore, the higher the concentration, the smaller the leaves.
