摘要: 为进一步优化核桃(Juglans regia L.)种子浸种时间, 对在不同浸种时间条件下播种的核桃幼苗发芽率、树体特征(株高、干茎、主根长、须根长、叶面积、叶绿素含量)与叶片营养物质(氮、磷、钾、钙、镁等矿质元素)进行主成分分析, 按照主成分贡献率计算不同浸种时间的综合得分, 筛选出最适合的浸种时间。结果表明, 主成分分析适用于优化核桃种子浸种时间, 得到浸种时间为5 d综合得分最高, 浸种1 d综合得分最低。

关键词: 主成分分析, 核桃(Juglans regia L.), 播种, 浸种时间

Abstract: In order to further optimize the seed soaking time of walnut (Juglans regia L.) in the mountain area, principal component analysis was carried out on seedlings germination rate, tree body characteristics(plant height, stem, root length, root length, leaf area, chlorophyll content) and leaf nutrients (N, P, K, Ca, Mg and other mineral elements) of walnut seedlings in the condition of sowing in different soaking time. According to the comprehensive score of principal component contribution rate to calculate the different soaking time, the most suitable soaking time were analyzed and screened. The results showed that the principal component analysis were suitable for walnut seed soaking time screening, and when the soaking time was 5 days, the total score was the highest, and the lowest score was in 1 day seed soaking.

Key words: principal component analysis, walnut(Juglans regia L.), sowing, seed soaking time
