蝴蝶兰倍性与叶部和花部性状的相关性
A correlation between ploidy levels and characters of leaf and flower in Phalaenopsis
摘要
Abstract
Objective To research the correlation between ploidy levels and main characters in Phalaenop-sis.[Method]Ploidy levels of 85 Phalaenopsis accessions were identified by using squash method , and the length and density of stoma , the length , width and thickness of leaf , the diameter and the number of flow-ers were also measured .[Result and conclusion]The results showed that in the 85 accessions there were three diploids (3.5%), nine triploids (10.6%) and 73 tetraploids (85.9%).Stomatal lengths and the length of tetraploid flower were obviously longer than those of diploid and triploid flower , while the density of stoma and the number of flowers were fewer than that of diploid and triploid (P<0.05).The differences of the stomatal cell length and diameter and the number of flower between diploid and triploid were not sig -nificant at 5%level, however, the stomatal density of triploid was less than that of diploid (P<0.05).The leaf length of tetraploid was significantly longer than that of diploid (P<0.05), while the difference of leaf length between diploid and triploid or between triploid and tetraploid was not significant ( P>0.05 ) .The difference of leaf width and thickness among diploid , triploid and teraploid were also not significant either ( P>0.05) .The ploidy levels were , to a large extant , positively associated to stomata length , leaf length and flower diameter , but negatively correlated with stomatal density and the number of flowers .关键词
