无籽西瓜在贵州的生产适应性研究

由于元籽西瓜种子本身种胚发育不全，故发芽率、成苗率低，幼苗生长缓慢，育苗困难；同时，因贵州省春季柢温、多雨、寡照等不良条件，无籽西瓜生产中容易出现畸形、空心、厚皮等现象，本试验对广西3号、雪峰花皮等7个无籽西瓜品种进行了引种、品比和栽培技术试验，初步试验结果表明，无籽西瓜的平均产量、中心可溶性固形特含量、产值均高于对照有籽西瓜，广西3号、雪峰花皮、红玫瑰无籽西瓜品种可在贵州省内适宜地区推广。

Productive Adaptiveness on Introduced No-seed Watermelon Cultivars in Guizhou

The abnormal hollow core and thick peel are often found in no-seed watermelon production because of lower germinating and survival rate,slow growth of young seedlings caused by the imfavourable condition of low temperature,rainy climate and scant sunshine in spring,Guizhou.The results from the comparation and cultivation experiment for seven introduced no-seed watermelon varieties show that the mean yield,soluble solids and yield value of no-seed watermelon are higher than those of CK (seed bearing watermelon).The no-seed cultivars，Guangxi 3,Xuefeng Huapi and Hongmeigui should be popuralized in the adaptable regions of Guizhou province.
