摘要:
 以矮牡丹花粉为材料，研究花粉的形态及不同培养基对矮牡丹花粉萌发及花粉管伸长的影响。结果表明，花粉萌发率与长球形花粉占花粉总数的百分率一致；适合矮牡丹花粉萌发的培养基为9%蔗糖+0.004 5%硼酸；低浓度(1×10-5~1×10-3 mol/L)的Ca2+促进了花粉管的伸长，高浓度(1×10-2～1×10-1 mol/L)的Ca2+抑制了花粉管的伸长，适合花粉管伸长的Ca2+浓度为1×10-3 mol/L；低浓度(0.1×10-3 mol/L)的Mg2+促进了花粉管的伸长，高浓度(0.2×10-3～1.8×10-3 mol/L)的Mg2+抑制了花粉管的伸长，适合花粉管伸长的浓度为Mg2+ 0.1×10-3 mol/L。
