水杨酸甲酯和茉莉酸甲酯对郁金香花香挥发物的影响
Effects of methyl salicylate and methyl jasmonate on volatile compounds of tulip flowers
摘要
Abstract
The effects of different concentrations of methyl salicylate(MeSA)and methyl jasmonate(MeJA)on the volatile compounds of tulip flowers were studied.Petals of tulip were sprayed with MeSA and MeJA of 50 μmol/L,200 μmol/L and 600 μmol/L.The volatile compounds of tulip flowers were de-termined and analyzed with headspace solid-phase microextraction(HS-SPME)coupled with gas chroma-tography-mass spectrometry(GC-MS).The results showed that the volatile compounds of tulip flowers mainly included alcohols,alkanes,terpenes,benzenes,ketones,and esters,with the highest total release of alcohols.The content of the six types of compounds showed different trends of changing after spraying MeSA and MeJA of different concentrations.The release of terpenes increased significantly under the treat-ment with 50 μmol/L MeSA or 200 μmol/L MeJA.4-Dodecanol,(E)-β-ocimene,and trans-3-hexen-1-ol were the main volatile compounds in tulip flowers.Among them,the release of(E)-β-ocimene in-creased under the treatment with different concentrations of MeSA and MeJA.The release of(E)-β-oci-mene under the treatment with 50 μmol/L MeSA and 200 μmol/L MeJA was 10 times and 3.3 times high-er than that of the control group.It is indicated that exogenous spraying of MeJA and MeSA significantly promotes the release of volatile compounds from tulip flowers.It will provide an important theoretical basis for selecting the appropriate concentration of MeJA and MeSA to improve the fragrance of tulip flowers.关键词
