Screening fruit cucumber cultivars for soilless cultivation in greenhouse
In order to screen out fruit cucumber cultivars suitable for soilless greenhouse,using 7 cultivars as experimental materials,14 agronomic traits and 5 nutrition quality of fruit cucumber cultivars were measured.Combined with principal component analysis and membership function analysis,different cultivars were evaluated comprehensively.The results showed that significant differences in plant traits,fruit quality,and yield among different cultivars.Among the 7 tested varieties,Zhexiu 6 had the largest plant height,stem diameter,internode length,and the vegetative growth is most vigor-ous.Zhexiu 4 had the highest soluble sugar content,and Tuoni 206 had the highest soluble solid content.Zhexiu 4 and Zhexiu 3 had the highest yield.Principal component analysis was conducted on the yield trait and nutrition quality traits and three principal components were proposed,with a cumulative contribution rate of 86.552%.The membership function analysis further suggested that the recommended order of the experimental fruit cucumber cultivars was:Zhexiu 4>Tuo-ni 206>Zhexiu 3.This study provides a certain reference for the selection of fruit cucumber cultivars suitable for soilless cultivation in greenhouse.
