摘要
自20世纪80年代以来,上海地区先后多次从大连、烟台等地引进甜樱桃,但时常出现"花而不实"、畸形果率偏高等问题。目前,通过筛选低需冷量的品种、应用物理或化学调控措施,甜樱桃已在上海、浙江等长三角地区实现了连续的小面积丰产。本研究以上海交通大学浦江绿谷实践基地的甜樱桃品种为研究对象,对不同砧穗组合、不同整形方式、是否经过单氰胺处理的甜樱桃品种的生物学特性进行评价。通过调查树高、干径、新梢长度和粗度、物候期、芽密度、花密度、花器官发育、坐果率以及果实品质等指标,综合评价不同品种的甜樱桃在上海地区的表现,以期为甜樱桃在上海等南方暖地的引种和丰产栽培提供理论支持。
Since the 1980 s,sweet cherry has been introduced from Dalian and Yantai to Shanghai for cultivation.However,it always shows unconformable symptoms,such as floral sterility,the high ratio of pistil deformity and so on.At present,sweet cherry has achieved continuously small-scale high yield through the screening of lowchilling varieties,chemical or physiological regulation measures in the Yangtze River Delta regions such as Shanghai,and Zhejiang.Taking the different varieties of sweet cherry in the Pujiang lvgu practice base of Shanghai Jiao Tong University as experimental materials,we assessed the biological characteristics of sweet cherries with different scion/rootstock combinations,different training systems,and with or without application of hydrogen cyanamide(HC)in this study.Additionally,we evaluated comprehensively the performance of different varieties of sweet cherry in Shanghai through investigating the tree height,trunk diameter,shoot length and thickness,phonological phase,bud and flower densities,floral organ development,fruit setting and fruit quality,which could provide theoretical support for the introduction and high efficiency cultivation of sweet cherry in Shanghai as well as other warm winter regions in Southern China.
