In order to explore the mechanism of 'brumal jujube' of maturation and scenescence and ethanol accumulation, We not only studied the quality and the post-harvest physiological and biochemical changes of 'brumal jujube' after treatment with hormone during storage, but also investigated the effects of CAi (C027%~10%02+ 2~5%C02) and CA2:(7%~10%02, C02 2%) on the changes of fermentation volatiles, activity of enzymes , the kind and content of sugar and organic acid during storage in this paper. Firstly announced the reason of ethanol accumulation under higher C02 level and discussed the mechanism of ethanol accumulation during the end of storage.

本研究以冬枣为试材，采后采用激素进行处理，通过对贮藏期间果实品质、生理生化指标、果实衰老相关指标和酶活性的测定，系统探讨了外源激素处理对果实采后品质及衰老的调控作用；另外对点红冬枣采用CA_1：(7％～10％O_2+2～5％CO_2)和CA_2：(7％～10％O_2、CO_2≤2％)进行气调贮藏，通过测定冬枣果实品质、乙醇发酵相关酶活性及代谢产物、糖酵解底物及参与三羧酸循环代谢的有机酸含量和种类，研究了冬枣贮藏后期乙醇积累的机制，探讨了枣果不耐高浓度CO_2贮藏的原因。

The qualitative analysis of the volatiles emitted from tea plants infested by Ectropis obliqua Prout with GC-MS or zNoseTM showed the similar results, however the relative contents of-3-hexen-1-ol,benzyl nitrile,indole,-caryophyllene obtained from both showed a certain difference.

结果表明：GC-MS与zNoseTM对茶尺蠖取食诱导的茶树挥发物的定性分析结果差别不大；但两者测定茶尺蠖取食诱导的茶树挥发物中顺-3-己烯醇、苯乙腈、吲哚、反-石竹烯等4种组分的相对含量有一定差异。

Anoplophora glabripennis Motshulsky (Coleoptera: Cerambycidae) is one of the most destructive insect borers of poplar trees in China. In recent years millions of poplar trees were damaged to death or near death in"Three-North Area", which caused heavy losses economically, ecologically and socially. Through the study on host selecting behaviors and behavioral responses to plant volatiles of A.

MethodsThe volatiles of Disporum bodinieri（Levl.et Vaut.

目的研究白龙须挥发性成分的化学组成。

In a climatically controlled chamber (28±1℃, L16:D8), E. splendens was planted in pots containing mixed vermiculite and perlite without Cu. At about 220 d after seeding, plants (around 65 cm in height) were used to collect their volatile using SPME. Eleven chemicals were identified using GC-MS, p-pinene, D-limonene, elsholtzia ketone, dehydro elsholtzia ketone,γ-elemene, humulene, caryophyllene, a-caryophyllene, and three sesquiterpenes. The most abundant volatiles were caryophyllene and y-elemene, followed by humulene and a-caryophyllene.
