Analysis of Leaf Volatiles from Crabapple(Malus sp.) Individuals of Different Juvenile Lengths
摘要
Abstract
[Objective] The aim of this experiment was to analyze the leaf volatiles of crabapple (Malus sp.) individuals at different juvenile lengths, and obtain their particular leaf volatiles, and provide reference for finding out a new breeding method. [Method] Volatiles of leaves from eight different crabapple individuls were evaluated with the method of head space-solid phase micro-extraction and gas chromatography - mass spectrometry (HS-SPME-GC-MS).Volatiles profiles of them were then compared. [Result] Eighty-four kinds of volatiles were detected with varied contents found in different individuals. The major leaf volatiles were 2-fluoro-acetamide, (Z)-3-Hexen-l-oI, diethyl phthalate and (Z)-3-hexen-l-ol acetate. Ten identical compositions including 3,7-dimethyl-l,3,7-octatriene, decanal, diethyl phthalate, 2,6,10-trimethylpemadecane, 2,6,10-1-tetradecanol; 2,6,10,14-tetramethyl pentadecane, hexadecane, l-dodecanol;2,6,10,15-tetramethyl heptadecane and Phthalic acid, diisobutyl ester were detected. [Conclusion] Leaf volatiles differ in eight crabapple individuals. But they are all based on esters and hydrocarbons, and the highest content is 3-Hexen-l-ol, acetate. The specific volatiles in the precocious crabapples are (2Z)-2-Penten-l-ol, acetate. (E)-cyclobutane, 1,3-butadienyl and 5,5-dibutylnonane.关键词
