摘　　要：[目的]了解贴梗海棠开花结果习性.[方法]观察贴梗海棠的花蕾变化,采用不同方式进行授粉.[结果]不同发育时期花朵的形态有着微妙的变化,花长在4月18 ～ 19日达高峰期,花径在4月16日以后出现急剧增大的现象,经过去雄套袋不授粉的植株收获3个果实,共有种子194粒.[结论]在不同的发育阶段花蕾的形态有很大的差别,花长和花径随着植物的生长而变大,到花期的最后出现短暂的变小,属于异花授粉植物.[Objective] The research aimed to study flowering habit of Chaenomeles speciosa.[Method] The study was mainly to observe buds change of Chaenomeles speciosa,and manipulate the different pollination.[Result] Different development period of flower type had a subtle change.Flowers grew on April 18 to 19 reached a peak.Flower diameter increased steeply after April 16.After emasculation without pollination bagging fruits harvested three plants,a total of 194 seeds.[Conclusion] Their form buds were very different in different development stages,with the growth of the flower length and flower plants becoming larger,but appeared a brief smaller in the finally flowering,a cross-pollinated plants.
