硼酸和蔗糖对马铃薯花粉离体萌发的影响

Influence of Boric Acid and Sucrose on Potatoes' Pollen Germination

以马铃薯（Solanum tuberosum L．）9个品种（系）为试材，研究了不同时间、不同浓度的硼酸和蔗糖的培养基对其花粉萌发的影响。结果表明：马铃薯花粉在含15％蔗糖＋90mg／L硼酸的培养基上萌发率最高；4～5h时为最好的观察时期；在试验条件下，青薯2号萌发率最高，萌发率达到83．25％，最低为02-1-1，萌发率为70．20％。

Study potatoes＇ pollen germination influence on condition that different treat time, different oric acid and suerose concentration treatment to nine species of potatoes. The result showed that the germination protortion of potatoes pollen was the highest on 15% sucrose ＋ 90 mg/L boric acid culture medium; and the best probationary period was the fourth to sixth hour. In this Condition, Qingshu No. 2 has the highest germination proportion of 83.25% ,with 02-1-1 has the lowest germination proportion of 70.20%.
