| 总结: | Abstract Vanda Mimi Palmer is the product of a cross
between Vanda Tan Chay Yan and Vanda tessellata. The
flower of this hybrid produces a sweet-smelling fragrance
during day time at the open-flower stage. This study aimed
to investigate the floral scent constituents in Vanda Mimi
Palmer. Scent emission analysis of this orchid was carried
out at different time points in a 24-h cycle and also at
different floral developmental stages. A comparison was
also made on the volatiles emitted by Vanda Mimi Palmer
and both of its parents. Gas chromatography-mass spectrometry(GC-MS) analysis showed that the scent of Vanda
Mimi Palmer was dominated by terpenoid, benzenoid, and
phenylpropanoid compounds. The identified terpenoids
were ocimene, linalool oxide, linalool, and nerolidol;
while the benzenoid and phenylpropanoid compounds
were methylbenzoate, benzyl acetate, phenylethanol, and
phenylethyl acetate. The emission of terpenoid, benzenoid,
and phenylpropanoid compounds was developmentally and
temporally regulated. Comparison of the volatiles emitted by both of its parents showed that the scent of Vanda Mimi
Palmer is dissimilar to that of its fragrant parent, V. tessellata. |
