摘要
研究了南瓜新品种‘甘栗’、‘华栗’果实发育期间及采后不同储藏温度下淀粉、可溶性糖含量、α-淀粉酶活性的变化规律。结果表明:两个南瓜品种淀粉的积累过程与最终含量存在较大差异,在南瓜果实生长阶段,淀粉、可溶性糖含量增加,但不同阶段各成分含量增加幅度不同,而α-淀粉酶活性变化规律相似;在6℃和25℃两个储藏温度下,两个南瓜品种的淀粉含量都下降,可溶性糖含量均升高,且25℃储藏条件的变幅较大。
The changes of the content of starch,soluble sugar and the activity of amylase were studied in two pumpkin varieties of ＇Ganli＇,＇Huali＇ during fruit growth and storage.The results showed that there were great differences in starch accumulation and final content between two pumpkin varieties.The content of starch,soluble sugar and the activity of amylase increased with fruit growth.At different storage temperature（6℃ and 25℃）,the content of starch declined and the content of soluble sugar increased,and larger changes was observed at 25℃.
