Abstract:

In order to screen Phalaenopsis varieties with fast growth,large number of flowers,short production cycles,and suitable for high-density cultivation in small pots,a total of 16 miniature Phalaenopsis varieties introduced and cultivated in Hangzhou were investigated for four growth traits including leaf length and leaf width,as well as six ornamental traits including flower number and flower diameter. Principal component analysis and cluster analysis were conducted. The results showed that the 16 varieties clustered into 5 groups;all of them showed vigorous growth and abundant flowers,but showed differences in flower diameter,number of branches,and growth potential. A comprehensive evaluation of varieties was carried out according to the overall ornamental effect,stable characters,and stress response,and eight varieties suitable for cultivation and production in Hangzhou were screened out. The established evaluation and analysis method has important guiding and reference significance for screening miniature Phalaenopsis varieties suitable for cultivation in Hangzhou and the Yangtze River Delta region.
