摘　　要：本试验对什锦丁香、小叶丁香和兰丁香一年2次开花的持续期、花量以及花器特性、花粉活力、结实率等进行了初步的研究。结果表明:3种丁香均表现为第一次开花花期集中,约为15～20d,花量大,花序大,花序长宽近等;花粉活力和结实率均较高。第二次开花花期持续时间长,约为50～66d,花期不集中,花量小,为第一次花期花量的1/6,花序较小,花序长大于宽;花粉活力均较高,为70%左右,活力下降速度快,而结实率均为0。The flower persistent period、flower output and flower organization structhre characteristics、 pollen viability、fructification rate of Syringa chinensis、Sytinga microphyla、Syringa meyeri are studied in this article.The results indicate that the first blooming period concentrate about 15 to 20days,the flower output and inflorescence are both large,length-width ratio is close;pollen viability and seed-setting rate are high.the blooming period is not concentrate and last about 50-66 days,compare with the first,the flower output is only about 1/6 of the second.The inflorescence is small,the length is bigger than width,pollen viability is 70%,all of the fructification radio are 0.
