摘　　要：合理负载是改善果实品质的重要途径。以生产上的主栽杏品种金太阳杏为试材,以不疏果为对照,研究了不同负载量(果间距5 cm、10 cm、15 cm和20 cm)对翌年花器官质量(花芽、花瓣和雌蕊重量,花瓣大小,雌蕊败育率)的影响。结果表明:疏果可以显著提高单花芽、单花瓣和单雌蕊的重量以及雌蕊的可溶性糖含量,提高花芽的可溶性糖含量,显著降低雌蕊败育率。生产上,金太阳杏疏果间距保持在15～20 cm,对提高翌年杏花器官质量效果较好。Reasonable loading was an important way to improve fruit quality.Using apricot variety Golden Sun as the material,the effect of loading on the flower organs quality including flower bud,weight of petal and pistil,size of petal and pistil abortion rate were studied.The results showed that fruit thinning enhanced the weight of single flower bud,single petal and single pistil,increased the content of soluble sugar of single flower bud and pistil,and significantly reduced the pistil sterile rate.In production,the space between fruits should kept 15-20 cm,which could improve the flower organs quality in the next year.
