摘　　要：为了找到快速准确筛选鉴定同化运转效能高的早熟大果型优良甜瓜品种及育种材料的新方法,选用15份不同类型甜瓜品种,采用手持折光仪测定可溶性固形物含量的方法,开展了甜瓜叶柄可溶性固形物含量变化规律的研究。结果表明:结果初期,在同日不同时段,同一甜瓜品种的不同叶柄可溶性固形物含量差异不显著;在同日相同时段,不同甜瓜品种的叶柄可溶性固形物含量存在显著差异;叶柄的可溶性固形物含量可以作为甜瓜品系早熟性判别的生理参考指标之一。To find a new method for rapidly selecting premature and bigger fruit melon materials and varieties with high ability of assimilate transporting,the variety law of soluble solids content in fifteen different melon varieties＇ leaf stalk were analyzed by hand held sugar instrument.The results showed that,at the different time of the same day,the soluble solids conten of different leaf stalk in the same variety had no obvious change,while at the same time of the same day,the soluble solids content of leaf stalk in different varieties had significant difference;the soluble solids of leaf stalk could be used as a physiological index for identifying premature in melon.
