Influence of Mineral Elements on Pollen Germination and Pollen Tube Growth of Apricot

摘要

The mineral element is one of the reasons that affect apricot pollen germination and pollen tube growth.The experiment isolated cultures 5 kinds of Xinjiang apricots pollens in solid mediums with some mineral elements (Ca2+,K+,Mg2+,Zn2+,Fe2+,Cu2+),and assays the rate of pollen germination and the length of pollen tube.The results show that the 6 kinds of mineral elements have different influences on pollen germination and pollen tube growth of Apricot.In an appropriate concentration range,Mg2+ has the strongest,2+improvement function on Kumaiti s pollen germination and pollen tube growth; Cu2+ has the strongest improvement function on Shushanggan's pollen germination and pollen tube growth; Ca2+ improvement function on Kalayulvke and Dayoujia pollen germination and pollen tube growth is the strongest; K+ has the strongest improvement function on Kabakehuanna's pollen germination and pollen tube growth.
