摘要:

为满足人们日益增长的消费需求,同时提供品种利用依据,试验筛选了几种鲜辣型口感的辣椒品种。以56份材料为试材,统计其田间农艺性状、辣椒素及鲜味氨基酸含量。结果表明:综合农艺性状分析发现,株高、果重变异系数较大,商品果颜色丰富、果形多样;辣椒素含量测定发现,各辣椒品种中辣椒素总含量差别较大,根据SHU指数进行辣度分级可分为1~6级,其中高辣型的有20份,包括果色为乳白色的玉龙椒、衢椒1号;氨基酸分析表明,鲜味氨基酸高于0.3 mg·g-1的品种有12份;相关性分析结果显示,鲜味氨基酸与天冬氨酸、赖氨酸、谷氨酸有显著相关性,且与天冬氨酸相关性最高,并得出鲜味氨基酸与天冬氨酸的线性回归方程:Y=0.061+1.1X;将农艺性状与辣椒素总含量及鲜味氨基酸含量进行相关性分析表明,果长与总辣椒素含量、鲜味氨基酸含量均存在极显著负相关关系(P<0.01),总辣椒素含量与鲜味氨基酸含量间存在极显著正相关关系(P<0.01)。

Abstract:

To meet the growing consumption demand and provide a basis for variety utilization, we select chili varieties with delicious and spicy taste. Fifty-six materials were used in the test, the common agronomic traits, capsaicinoids content, and delicious amino acid content were statistically analyzed. The results showed that comprehensive analysis of agronomic traits revealed a large coefficient of variation in plant height, fruit weight, showing various color and diverse fruit shapes. The determination of capsaicin content found that there were significant differences in the capsaicinoids content among different chili pepper varieties. According to the SHU index, the pungency degree can be classified into 1-6 levels, with 20 extremely spicy varieties, including Yulongjiao and Qujiao No.1 which with ice-cream color. Analysis of delicious amino acids showed that there were 12 varieties with delicious amino acids higher than 0.3 mg·g-1, the correlation analysis results showed that there was a significant correlation between delicious amino acids and aspartic acid, lysine, and glutamic acid, and had the highest correlation with aspartic acid. The linear regression equation between delicious amino acids and aspartic acid was described as Y=0.061+1.1X. Correlation analysis was conducted between agronomic traits, total capsaicin content, and delicious amino acid content. There was a negatively significant correlation (P<0.01) between fruit length, capsaicinioids content, and delicious amino acid content. There was a positively significant correlation (P<0.01) between capsaicinioids content and delicious amino acid content.

Key words: delicious and spicy, pepper, correlation analysis
