本实验以新鲜的牡丹花粉为材料,研究不同浓度的蔗糖,硼酸对牡丹花粉萌发及花粉管生长的影响,以探讨牡丹花粉萌发的合适条件。研究结果显示:2.5%的蔗糖溶液对牡丹花粉萌发及其花粉管生长起促进作用,浓度大于2.5%的蔗糖溶液对其有抑制作用。在2.5%的蔗糖溶液中加50.00 mg/L的硼酸溶液,对牡丹花粉萌发和花粉管生长有明显的促进作用,而100.00 mg/L的硼酸溶液能抑制牡丹花粉萌发。可见,适当浓度的蔗糖和硼酸溶液能够促进牡丹花粉的萌发。
In this experiment, fresh peony pollen was used to study the effects of different concentrations of sucrose and boric acid on the pollen germination and pollen tube growth of Peony to discuss the suitable conditions for pollen germination. The results showed that 2.5% sucrose solution could promote the pollen germination and pollen tube growth of Peony, and the sucrose solution with concentration greater than 2.5% could inhibit the growth of pollen tube. The addition of 50.00 mg / L boric acid solution to 2.5% sucrose solution could significantly promote pollen germination and pollen tube growth, while 100.00 mg / L boric acid solution could inhibit pollen germination. Visible, the appropriate concentration of sucrose and boric acid solution can promote the germination of peony pollen.
