Effects of exogenous BRs on flowering characters of Phalaenopsis aphrodite
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.
