| 摘 要： | 采用离体花粉培养法和方差分析方法,研究了钙(Ca2+)、锌(Zn2+)、钼(Mo6+)3种无机元素对狭叶重楼花粉萌发和花粉管生长的影响。结果表明:高浓度的Ca2+明显抑制花粉的萌发和花粉管的生长,低Ca2+对花粉的萌发和花粉管的生长也有轻度的抑制作用;高浓度的Zn2+抑制花粉的萌发和花粉管的生长,适量的Zn2+能促进花粉管的生长,低浓度的Zn2+对花粉的萌发和花粉管的生长无明显影响;高浓度的Mo6+抑制花粉的萌发和花粉管的生长,低浓度的Mo6+对花粉的萌发和花粉管的生长无明显影响。

| Abstract: | The effects of calcium(Ca2+),zinc(Zn2+) and molybdenum(Mo6+) on pollen germination and pollen tube growth of Paris polyphylla var.stenophylla were investigated through tissue culture and analysis of variance.The results indicated that Ca2+ inhibited the pollen germination and pollen tube growth.When the concentration of Zn2+ was high,the pollen germination and pollen tube growth would be inhibited.If the concentration of Zn2+ was low,it had no influence on the pollen germination and the growth of pollen tub... |
