摘要：

蝴蝶兰开花性状影响其商品价值,以蝴蝶兰为材料,试验不同浓度的外源油菜素内酯(BRs)处理对3个品种的蝴蝶兰花葶数量、花葶长、花朵数、花朵直径、花期长度等开花性状的影响。结果表明,外源BRs处理对蝴蝶兰花葶数并无显著影响,但能使蝴蝶兰花葶提前发育,促进花葶伸长,增加花葶直径,并且BRs能使花朵提前开放,提升花朵数与花朵直径,延长开花花期。不同浓度的BRs处理,可以提升蝴蝶兰开花品质,不同处理浓度之间对不同品种蝴蝶兰开花性状的影响有显著差异。

Abstract:

The flowering characteristics of Phalaenopsis aphrodite affect its commercial value.Taking three Phalaenopsis aphrodite varieties as the experiment materials, this paper examines the impact of exogenous brassinolide (BRs) on their flowering characteristic, including the number and length of scapes, flower numbers,flower diameters,and flowering duration.The results demonstrate that the exogenous BRs usage does not impact the number of scapes significantly,but can enhance the scapes growth and extend both its length and diameter. Moreover, BRs can help Phalaenopsis aphrodite bloom early, increase flower numbers, expand flower diameters, and prolong flowering duration.The use of different concentrations of BRs can enhance the Phalaenopsis aphrodite flower quality, and the impact of different concentrations of BRs on different Phalaenopsis aphrodite varieties are significantly different.

Key words: Phalaenopsis aphrodite, exogenous BRs, flowering characteristics
