【摘要】 为提高小果型西瓜品质,本试验以椰糠作为基质栽培,进行了小果型西瓜品种比较与营养成分分析,同时以超越梦想为试验材料,比较了椰糠栽培下自根苗与嫁接苗果实品质差异。结果表明:在外观品质方面,7个品种果型基本为长圆形,果皮薄,可食用的果瓤部分比例较高;在营养品质方面,超越梦想、红灵和红香秀3个品种比较好;在氨基酸和糖的分析上来看,超越梦想和L600果实内这两者的组成与含量也显著优于其他品种;在椰糠基质栽培条件下,超越梦想综合品质最好。嫁接苗果实的可溶性糖、VC含量以及果糖含量明显高于自根苗的果实,为小果型西瓜的椰糠基质栽培提供了依据。更多还原

【Abstract】 In order to improve the quality of small fruit watermelon,coconut bran was used as substrate in this experiment.The comparison and nutrient composition analysis of small fruit watermelon were carried out.Meanwhile,the differences of fruit quality between self rooted seedlings and grafted seedlings under coconut bran cultivation were compared with those of super dream.The results showed that,in the aspect of appearance quality,the fruit shape of 7 varieties was basically oblong,the peel was thin,and the proportion of edible pulp was higher;in terms of nutritional quality,the three varieties of chaomengxiang,Hongling and Hongxiangxiu were better;in terms of amino acid and sugar analysis,the composition and content of these two varieties were also significantly better than those of other varieties,which were planted in coconut bran substrate under the training conditions,the comprehensive quality of surpassing the dream was the best.The contents of soluble sugar,VC content and fructose in the fruits of grafted seedlings were significantly higher than those in the fruits of self rooted seedlings,which provided a basis for the cultivation of small fruit watermelon with coconut bran.更多还原
