摘要
对山茱萸盛花期拉技选取样株调查表明,同一花序中的花,开花有前有后,座果率有高有低。雌蕊有7d以上的授粉期,授粉后3d花瓣凋萎,柱头变褐。但总体着果率低,8%以上属高座果率。通过不同的保花保果技术处理,效果显著而稳定。
Observation on sample branches during full-bloom period Cornus officinalia demonstrated that flowering time was different even at the same inflorescence and with different percentage of fertile fruit. The pistile needed more than 7 days for pollination, 3days after pollination, petale wilt and stigma became brown. But it had low percentage of fertile fruit. Different techniques of flower and fruit retention had evident and stable effect.
