平榛(Corylus heterophyllaFisch.)是东北地区的主要经济林树种,其坚果是食用榛子的主要来源。利用平榛进行榛子遗传改良,是培育新品种的重要方法。通过多年的研究总结出一套平榛花粉收集技术,为杂交育种提供了技术的保证。透光率对雄花序生长的影响呈负相关,透光率越低,雄花序开花时间延长,花序也伸的长,花粉产量少;而透光率对花粉产量则相反,透光率越高,雄花序开花时间越短,花粉产量多。雄花生长与花粉产量受种源、水培时间的影响,其差异性显著。
Corylus heterophyllaFisch. Is a major economic tree species in the northeastern region. Its nuts are the main source of hazelnut for consumption. The use of hazelnut hazelnut genetic improvement, is an important way to cultivate new varieties. Through years of research, a set of flat hazel pollen collection technology has been summarized, which provides technical assurance for hybrid breeding. The light transmittance had a negative correlation with the inflorescences of male inflorescences. The lower the light transmissivity was, the longer the flowering time of the male inflorescences was, the longer the inflorescences were and the less the pollen yield was. The higher the light transmittance was, the higher the light transmittance was , The shorter the flowering male flowering, pollen yield and more. Male flower growth and pollen yield were affected by provenance and hydroponic time, and the difference was significant.
