【摘要】 旨在探索提高雷竹结实率的技术途径。用染色法和加硼酸 (H3BO3)培养基法对雷竹花粉生命力进行测定 ,并对雷竹进行人工辅助授粉效果的研究。结果表明 :雷竹花粉萌发率低 ,且活力丧失很快 ;喷施适当低浓度硼酸有利于花粉萌发 ;人工辅助授粉可提高雷竹结实率 ;种子败育和种实害虫危害可能是雷竹结实率低的重要原因之一。提高雷竹结实率在技术上是可能的。图 1表 3参 7更多还原

【Abstract】 The test aimed to search the technology curriculum of raising seed rate of  Phyllostachys praecox.The pollen vigor,the influence of B(H 3BO 3) to pollen germination,the effect of artificial pollination were studied.The results show that the pollen germination rate of Ph.?praecox  is both weak and quick collapsing.Sprying proper low concentration B is beneficial to pollen germination.Art pollination may help to raise the seed rate of  Ph.?praecox;The decay of seed and the disservice of worm may be one of the important factors that cause low seed rate of Ph.?praecox.So it is possible in technology to raise the seed rate of Ph.?praecox.更多还原
