不同甜瓜品种含糖量差异分析

以"28-白皮"、"甜帅"、"菜瓜"、"特大绿麻瓜"、"玉脆×3-2-2"、"日本甜宝"、"东甜001"、"华抗王"、‘Topmark’、"白雪公主"、"北亚绿麻瓜"、"红瓤酥"、"红城脆"、"26-黄白皮"、"东甜002"、"过路白"、"新龙甜"、"珍珠"等18个甜瓜品种为试材,通过测定不同品种甜瓜的还原糖、果糖、葡萄糖的含量,比较分析不同品种间各糖分含量的差异。结果表明:"珍珠"与所有品种在还原性总糖、果糖及葡萄糖差异分析中,均表现为显著或极显著差异。根据3种含糖量的差异分析结果进行聚类分析,18个甜瓜品种分为2类,第1类种含有17个甜瓜品种,第2类只有"珍珠"1个品种,说明其在含糖量这一指标上与其它甜瓜材料具有较大差异。

Variance Analysis of Sugar Content in Melon

Eighteen muskmelon accessions included ’No.28 white color skin’,’Tianshuai’,’Vegetable melon’,’Teda lvmagua’,’Yucui×3-2-2’,’Japanese sweety baby’,’Dontian001’,’Huakangwang’,’Topmark’,’White snow princess’,’Beiya lvmagua’,’Hong rongsui’,’Hong chengcui’,’No.26 white yellow color skin’,’Dongtian 002’,’Guo lubai’,’New longtian’ and ’Pearl’ were used as test materials to estimate different total sugar content,fructose and glucose content in using by mixed sample methods for investigate variance analysis in muskmelon accessions.The results indicated that eighteen accessions sugar content in all melon accessions was variance significant especially for ’Pearl’.Cluster analysis based on the variance three kinds of sugar content variance analysis,the results showed that eighteen melon accessions were clustered into two groups which the first group consisted of 17 melon accessions and the second group was only one accession ’Pearl’.It indicated ’Pearl’ had a moderately difference from other melon accessions when comparing sugar contents.
