摘要:
为了探讨哈密瓜不同留果节位对其果实生育期、产量及品质的影响,以西密25、白玫、风味5、风味4和雪蜜5个品种为试材,分别在低节位(9~11节)、中节位(12~14节)和高节位(15~17节)留果,采取吊蔓栽培,单蔓单果整枝方式进行试验。结果表明,不同留果节位对试验品种生育期的影响较大,留果节位低成熟早,比高节位留果成熟早5~7 d;风味5、风味4和白玫3个品种不同留果节位对其果实产量及品质无影响,雪蜜仅果形指数有显著影响;西蜜25除果形指数和果肉厚度不受留果节位影响外,单果重量和中心可溶性固形物含量受留果节位的影响显著,低节位坐果的果实比中、高节位大,且外观网纹好,无裂痕,商品性高。

Abstract:
Five hami melon varieties Ximi 25, Baimei, Fenwei 5, Fenwei 4 and Xuemi were used to study the effect of fruit position on the growth duration, yield, and fruit quality. All plants were grown using the cultivation method of single tendril hanging in the autumn greenhouse in the west area of Guangdong province. The treatments included setting one fruit at the lower (9-11 node), middle (12-14 node), or upper (15-17 node) position on the tendril. The results showed that fruit position had a big influence on the growth duration of hami melon varieties. Fruits on the low nodes matured 5 to 7 days earlier that those on the upper nodes. Differences in fruit weight, fruit shape index, flesh thickness, and soluble solid content of Fenwei 5, Fenwei 4, and Baimei were not observed among treatments; however,the fruit shape index in Xuemi was significantly different among treatments. Significant differences in fruit weight and soluble solid content were also observed in Ximi 25. Compared to other two fruit position (middle and upper), the fruit on the lower node was larger and having good cob webbing without cracks, showing a good marketing character.
Key words:  Hami melon  fruit setting node  varieties  fruit growth  fruit qualities
