Abstract:
Taking 50 species of Phalaenopsis as experimental materials,their growth character indexes (leaf length,leaf width,root number,root maximum length,plant weight) of different periods of growth were measured and analysed.The correlation between growth regularity and phenotypic traits of Phalaenopsis was studied,providing reference for breeding and parent selection of Phalaenopsis.The results showed that,1)in the 3.5 inch cup weight and 3.5 inch cup gain in weight,the weight and the gain in weight of R60 (mini flower) were the smallest,they were 16.15 g and 8.11 g,respectively；the weight and the gain in weight of 2W6 (large flower) were the largest,they were 48.69 g and 38.07 g,respectively；they were significantly different.And the size of the two varieties in the 3.5 inch cup weight and the 3.5 inch cup gain in weight was consistent with the size of the small and large flower plants of the mature Phalaenopsis in the actual cultivation.2）The weight variation coefficient of the 3.5 inch cup was below 45%of 50 cultivars of Phalaenopsis,the genetic stability of varieties were good.3）The 3 characters of 2.5 inch cup weight,3.5 inch cup leaf length and 3.5 inch cup leaf width had the greatest impact on the growth performance of Phalaenopsis.The growth performance of Phalaenopsis could be selected by 1.5 inch cup weight in the early stage of tissue culture and transplanting in greenhouse.
