摘要
以全国16个省区50个品种大蒜与对应土壤为材料,分析大蒜鳞茎中大蒜素、硒元素、锗元素、可溶性糖、可溶性蛋白的含量,测定蒜瓣数、蒜头质量等7个鳞茎性状及土壤化学性状指标,通过主成分分析对鳞茎性状进行综合评价,分析大蒜鳞茎与产地土壤化学性质的相关性。结果表明:大蒜素、硒、锗和可溶性糖4个主成分累计方差贡献率达到79.8%,反映大蒜品种鳞茎品质的基本信息。鳞茎营养品质大蒜素、硒、锗、可溶性糖、可溶性蛋白及表型品质蒜瓣数、蒜头质量综合排序,品质较好的(F≥0.5)品种是‘苏02’‘苏01’‘贵02’‘豫07’和‘晋01’,品质一般(0≤F<0.5)的品种19个,品质较差(F<0)的品种超过一半。相关分析表明,土壤养分含量与大蒜品质间的相关性较小,只有硫元素与大蒜素和可溶性糖显著正相关,土壤pH与大蒜锗含量显著正相关,土壤N含量与大蒜可溶性糖极显著正相关。
The contents of allicin,selenium,germanium,soluble sugar and soluble protein in garlic bulbs of 50 collections and the corresponding soils from 16 provinces and regions of maing arlicpro ducing areas in China were analyzed.The bulb traits such as clove number and bulb mass were also measured.The quality of different garlic collections was evaluated by principal component analysis,and the correlation between garlic bulb quality and the corresponding soil chemical properties was also analyzed.The results showed that the cumulative variance contribution rate of the four main components of allicin,selenium,germanium and soluble sugar reached 79.8%,which reflected the basic information of bulb quality of garlic collections.Bulb nutritional quality allicin,selenium,germanium,soluble sugar,soluble protein,garlic cloves number of phenotypic quality and garlic head mass were comprehensively ranked.thegood quality(F≥0.5)varieties were‘Su 02’‘Su 01’‘Gui 02’‘Yu 07’and‘Jin 01’,19 varieties belonged to general quality(F<0.5),and more than half of the varieties belonged to poor quality(F<0).Correlation analysis showed that there was a small correlation between soil nutrient content and garlic quality,only sulfur element was significantly positively correlated with allicin and soluble sugar,soil pH was significantly positively correlated with garlic germanium content,and soil N content was significantly positively correlated with garlic soluble sugar content.
