Phenotypic divergence among the 24 accessions belonging to a collection of six species of Capsicum from different geoclimatic regions available in field gene bank of CIMAP, Lucknow, India, was quantified by multivariate
analysis for 12 quantitative and qualitative traits. Based on their values, all 24 accessions were grouped into six clusters
such that the genetic stocks within cluster had smaller D
2 values among themselves than those belonging to different clusters. The accessions of Capsicum annuum were distributed in different clusters in morphotyping representing different species, suggesting that taxonomic characteristics
are not always related to agronomic traits. No parallelism/association was found between geographical and phenotypic diversity.
Accessions 15 and 23 (clusters V and VI, respectively) had distinct identity. The three characteristics that played the greatest
role in differentiation were fruit diameter, number of fruits per plant, and leaf diameter, which can be utilized as conventional/morphological
markers for the improvement of chilli yield and obtaining good segregants in chilli breeding programs. 相似文献

响应面法优化超微粉碎辅助提取辣椒红素工艺研究 总被引:1,自引:0,他引:1
为优化超微粉碎辅助提取辣椒红素工艺,采用6种提取液对辣椒红素进行提取,对比结果,选择95%乙醇作为提取液.选择液料比、微粉细度、提取时间、提取次数为自变量,辣椒红素提取相对量为响应值,采用Box-Behnke,试验设计法,研究各自变量及其交互作用对辣椒红素提取相对量的影响,利用Design-Expert7.0软件对实验数据进行回归分析,并作出响应面图,得到二次数学模型方程,确定出辣椒红素的提取最佳工艺参数为常温条件下,液料比7∶1,超微粉碎细度500目,提取时间14.00 min,提取次数2次. 相似文献

[目的]筛选最佳提取工艺条件,并从原料的处理和提取剂的选择上改良传统工艺。[方法]利用索氏提取法从干红辣椒中提取辣椒红素,以辣椒红素的色价为指标在单因素实验的基础上进行正交实验,并对实验结果进行方差分析。[结果]辣椒红素的吸光度在提取温度为80℃时最高。当温度大于80℃时,辣椒红素的得率与80℃提取时的相差不大,而吸光度小于80℃提取时的。提取时间为4h时,辣椒红素吸光度最高,大于4h时辣椒红素的得率偏高。提取辣椒红素的最佳工艺条件是以正己烷为提取剂,在80℃和料液比为1:20的条件下提取4h,在此条件下重复3次的辣椒红素色价分别是68.6、69.0和68.9。[结论]提取辣椒红素的主要影响因素是温度,其次是提取时间,影响最小的是料液比。 相似文献
