产地绿竹笋品质及土壤养分的主成分与典型相关分析

doi: 10.11833/j.issn.2095-0756.2012.05.012

摘要: 应用主成分、典型相关分析方法研究了福建和浙江的12个产地绿竹Dendrocalamopsis oldhami的鲜笋质量指标与土壤养分之间的相关性。结果表明:依据笋品质性状的前3个主成分累积方差贡献率达到84.658%,可选取前3个主成分作为笋品质的综合指标。鲜笋的还原糖、水溶性总糖质量分数最能反映笋营养状况,其次为水分,第三为蛋白质与总灰分。笋品质性状与土壤养分指标有着显著典型相关关系,尤其是第1典型变量之间相关系数为0.999 99,其相关信息接近占2组性状总信息的100%。来自土壤养分指标的第1典型变量中pH值、全氮和有机质质量分数对绿竹品质具有较好的预测能力,而鲜笋的还原糖、水溶性总糖、水分可被对方变量的第1典型变量所预测。表3参15
