摘要: 为了探讨上海地区甜樱桃结实不良的原因,以5年生欧洲甜樱桃(Prunus avium L.)为试验
材料,就其花器发育状况进行了探讨。结果表明,上海地区生长的甜樱桃花芽形成良好,雌蕊、雄蕊外观形态无异常。花粉粒形态正常,发芽率达50%左右,但有98.2%的子房发育不正常,其中无胚珠分化的子房占26.3% ,有胚珠而无胚囊分化的子房占71.9% 。胚珠、胚囊发育不良是上海甜樱桃不能正常结实的主要原因。

Abstract: In order to explore the reason for poor fruit set in sweet cherry grown in Shanghai area,the development of flower organs was investigated with 5-year-old sweet cherry(Prunus avium L.)trees which were planted in tlle research orchard of Shanghai Jiaotong University.Results showed that floral diferentiation and appearance of stamen and pistil during their development were normal for sweet cherry in Shanghai area.The microscopic observations revealed that poNen developed well and polen germination rate reached about
50%.However.98.2% of ovary failed to develop,among which tllere was 26.3% of ovaries witllout ovule, and 71.9% of ovaries witll ovule but witllout embryo sac.The result indicated tllat undeveloped ovule and embryo sac are tlle main reason for poor fruit set of sweet cherry in Shanghai area.
