| Abstract (English): |
To investigate the impact of different ecological regions on the agronomic and quality traits of Guizhou local peanut germplasm resources and identify key ecological factors, a study was conducted planting 105 different germplasm resources across three distinct ecological regions simultaneously. The results revealed significant variations in both agronomic and quality traits among the test materials in the three ecological regions. Principal component analysis identified plant productivity, total branch number, fat content, and oleic acid content as the most influential agronomic and quality parameters for Guizhou local peanut germplasm resources. The comprehensive evaluation ranked the ecological regions as follows: Yanhe County > Pingba District > Huaxi District. Core soil nutrient factors impacting different germplasms included alkali-hydrolyzable nitrogen, available phosphorus, available potassium, pH value, and salinity. Correlation and redundancy analyses demonstrated a positive relationship between temperature and plant height, length of the first pair of lateral branches, and productivity per plant during the growing season, while a negative correlation was observed between temperature and days of the growth period. Precipitation showed a positive correlation with protein and sucrose during the growing season, whereas altitude exhibited a negative correlation with protein and sucrose levels. These findings offer a crucial theoretical foundation for optimizing regional planting strategies and implementing precise cultivation management practices for test materials.

为解析不同生态区对贵州地方花生种质资源农艺及品质性状影响, 探寻关键生态因子, 本研究于三个不同生态区同时种植 105 份不同种质, 对三个点花生种质资源开展农艺性状与品质性状分析, 针对不同生态区土壤养 分、气象信息与农艺性状、农艺品质性状进行关联分析。研究结果显示, 参试材料农艺品质性状在三个生态区存在 显著差异; 通过主成分分析可知, 单株生产力、总分枝数、脂肪、油酸含量为不同生态区最为显著的农艺品质性状关 键影响因子; 根据综合评分计算表明, 不同生态区综合评价结果为沿河县＞平坝区＞花溪区; 土壤中碱解氮、速效 磷、速效钾、pH 值、盐分等是影响不同种质主要核心土壤养分因子; 相关性分析与冗余分析表明, 生长季温度与株 高、第一对侧枝长、单株生产力呈强正相关关系, 与生育期天数呈显著负相关, 生长季降水与蛋白质、蔗糖呈较强正 相关, 海拔与蛋白质、蔗糖呈极强负相关, 这表明气象因子与土壤养分协同作用, 显著影响参试材料农艺品质性状 表现。这些研究发现将为贵州花生区域化种植布局与精准栽培管理提供重要的理论依据。 [ABSTRACT FROM AUTHOR] |
