Analysis of mineral elements content in different cucumber varieties based on multivariate statistics
In order to investigate the differences in the mineral element content of different cucumber varieties(including strains),a multivariate statistical approach was used to examine and compare the eight mineral element content of the leaves of various cucumber varieties,as assessed by an atomic absorption spectrophotometer.The results shown that many cucumber varieties have high mineral element content,with a pattern of K＞Ca＞Mg＞Na＞Fe＞Zn＞Mn＞Cu.The variety with the highest content of K and Na,Ca and Mg,Fe and Mn,Zn,and Cu is 18-Tsumegreen-60,Tsubasa Morning Round,S312,20-Tsumegreen 80,and WGP91,respectively.There are also differences in the proportion of mineral elements in the leaves of different cucumber varieties,with significant differences in K:Na and Fe:Mn,while small differences in Ca:Mg and Zn:Cu.Four groups of 20 cucumber types may be identified:the first group has lower Ca and Mg concentration but greater K,Na,Mn,Cu,Zn,and Fe content.The K content is lower in the second category,while the Ca and Mg content is higher.The third group has higher K content and lower Mg content.The fourth group has higher K,Ca,and Mg content but lower Mg content of S29.According to correlation analysis,a significant positive correlation existed between Mg and Ca,Na and K,and Mn and Fe.Principal component analysis revealed that the top three combinations of mineral element content scores were S312,Jin Early Round,and 20-Zin Green 60,while the bottom three combinations were S26,18-Zin Green 60,and 19-Zin Green 80.The research results may provide a theoretical foundation and practical support for scientific and acceptable fertilization as well as cucumber variety breeding.
