摘要
为探究辣椒品质的综合评价方法及影响辣椒品质的关键气象因子,以卓椒52、骄阳6号和辣研12号3个辣椒品种为供试材料,在贵州省麻江县、云南省砚山县、湖南省长沙市、重庆市石柱县4个辣椒主产区进行栽培试验,并进行辣椒品质指标测定,采用相关性分析、主成分分析、逐步回归等方法,明确影响辣椒品质的关键气象因子,建立辣椒品质综合评价模型与气候品质评价模型,并对4个辣椒主产区的气候资源优势进行比较。结果表明,种植于4个种植点的3个辣椒品种品质指标存在较大的变异,其中辣椒二氢辣椒素含量、辣椒红素含量、辣椒素含量的变异系数均在50%以上,而还原糖含量、氨基酸含量、粗脂肪含量、粗纤维含量变异系数均在20%以内。种植于云南省砚山县的卓椒52品质综合评价最优,而供试的3个辣椒品种种植于贵州省麻江县的辣椒品质总体优于其他3个种植区。根据主成分载荷值筛选出的辣椒品质指标为辣椒素含量、二氢辣椒素含量和粗脂肪含量。影响辣椒品质的关键气候因子为辣椒定植至采收期的平均相对湿度和总降水量。4个种植点的气象因子主成分得分分属4个象限,而7个气象因子的主成分载荷值分属3个象限,其中,与辣椒品质相关的关键气象因子平均相对湿度和总降水量位于第2象限,与贵州省麻江县的气象因子主成分得分一致。说明贵州省麻江县的气象条件有利于提升辣椒的品质。本研究结果为进一步的辣椒优质栽培、品质评价及种植区划提供了依据。
In order to explore the comprehensive evaluation methods of pepper quality and the key meteorological factors affecting pepper quality,cultivation experiments were carried out in four main pepper producing areas of Majiang in Guizhou,Yanshan in Yunnan,Changsha in Hunan and Shizhu in Chongqing with three pepper varieties(Zhuojiao 52,Jiaoyang 6 and Layan 12)as experimental materials,and the quality indices of pepper were determined.The key meteorological factors affecting the quality of pepper were determined by correlation analysis,principal component analysis and stepwise regression.The comprehensive evaluation model and climate quality evaluation model of pepper quality were established,and the advantages of climate resources in the four main pepper producing areas were compared.The results showed that there were great variations in the quality indices of three pepper varieties planted in four planting sites.The variation coefficients of dihydrocapsaicin content,capsanthin content and capsaicin content in pepper were all above 50%,while the variation coefficients of reducing sugar content,amino acid content,crude fat content and crude fiber content were all within 20%.The comprehensive evaluation of the quality of Zhuojiao 52 planted in Yanshan County,Yunnan province was the best,while the quality of the three pepper varieties planted in Majiang County,Guizhou province was better than that of the other three planting areas.The quality indices of pepper screened according to the principal component load values were capsaicin content,dihydrocapsaicin content and crude fat content.The key climatic factors affecting the quality of pepper were the average relative humidity and total precipitation from planting to harvest.The principal component scores of meteorological factors in four planting sites belonged to four quadrants,while the principal component load values of seven meteorological factors belonged to three quadrants.Among them,the average relative humidity and total precipitation of the key meteorological f
