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。
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 tis- sue 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 influ- ence on the pollen germination and the growth of pollen tube. When the concentration of Zn2+ was within a certain range, the pollen tube growth would be enhanced. When the concentration of Mo6+ was high, the pollen germination and the growth of pollen tube was inhibited. If the concentration of Mo6+ was low, it had no influence on the pollen germination and the growth of pollen tube.
