摘要:
以杉木实生苗为试验材料,选择萘乙酸(NAA)、吲哚-3-乙酸(IAA)、6-苄氨基嘌呤(6-BA)等3种生长调节剂,采用单因素试验,各因素设置3个浓度,研究不同生长调节剂对铝胁迫下杉木幼苗叶绿素荧光特性的影响。结果表明,铝胁迫对杉木幼苗的叶绿素荧光参数造成了影响,与CK(无Al3+、pH值为4.5的Hoagland-Arnon营养液)相比,CKAL处理(有Al3+、pH值为4.5的Hoagland-Arnon营养液)下的初始荧光(Fo)、最大荧光(Fm)、可变荧光(Fv)、PSⅡ实际光化学效率(QY)、PSⅡ最大光化学效率(Fv/Fm)和PSⅡ潜在光化学活性(Fv/Fo)总体呈现先升高后降低又升高的趋势。总的来说,生长调节剂在一定程度上提高了杉木叶片的FvFmFv/FmFv/Fo、光化学猝灭系数(qP)、QY,降低了Fo、非光化学猝灭系数(NPQ)。
