摘? ? 要:為了篩選優良的線椒品種資源,以資源圃收集的18份線椒品種為材料,對4個品質指標的含量進行測定和分析,并利用隸屬函數值法對其品質指標進行綜合評價。結果表明,18份線椒品種的粗脂肪、粗纖維、維生素C和辣椒素的平均含量分別是0.39 g·100 g-1、9.60 g·100 g-1、170.67 mg·100 g-1和5.43 mg·100 g-1。各個品質指標在不同線椒品種之間的含量差異較大,其中以辣椒素含量的變異系數最大,為43.01%,最小的為粗纖維,只有9.55%。通過隸屬函數分析表明,4個品質指標的平均隸屬度在0.26~0.59之間,相差0.33,品種間差異較大。辣椒品種品質性狀分析,可為辣椒種植時品種的選擇提供參考,同時,也為辣椒品種資源的創新利用以及新品種的選育提供可靠的依據。

Abstract:In order to screen the excellent germplasm resources of the line pepper, the content of the 4 quality indicators was determined and analyzed by using 18 line pepper varieties collected from the resources, and the quality index was comprehensively evaluated by the membership function value method. The results showed that the average contents of crude fat, crude fiber, vitamin C and capsaicin in 18 line pepper were 0.39 g·100 g-1, 9.60 g·100 g-1, 170.67 mg·100 g-1 and 5.43 mg·100 g-1, respectively. Four quality characters among 8 line pepper varieties varied greatly, the variation of capsaicin content reached highest, 43.01%, the variation of crude fiber was smallest, 9.55%. The membership function analysis showed that the average membership value of the 4 quality traits was in the range of 0.26 and 0.59, with a difference of 0.33. Those results can provide reference for the selection of varieties for production and can provide reliable basis for linepepper varieties innovation and breeding in the future.

辣椒(Capsicum annuum L.)為一年生或有限多年生茄科辣椒屬草本植物,線椒是辣椒的一個變種。辣椒是人們生活上主要的鮮食蔬菜和辣味調味劑,富含辣椒素、辣椒紅色素、維生素C、多糖等有效成分,具有頗高的營養價值和保健功能[1],其中,辣椒素具有抗癌、抗菌消炎、防治心腦血管疾病和調節免疫力等功效[2-5]。辣椒是全球最為重要的經濟性蔬菜作物之一,在我國的種植面積是僅次于大白菜的第二大蔬菜作物,我國已成為全球最大的辣椒生產、消費和出口國,約占全球生產總量的50%[6]。
目前,對貴州地方辣椒品種的品質分析報道較多,鐘霈霖[7]對貴州省124份地方辣椒品種的生物學特性、干物質、維生素C和辣椒素方面進行初步分析,這一研究為貴州地方辣椒品種品質分析及利用奠定了基礎。……
