Description

Technical Field

[0001] The invention relates to the technical field of plant research, in particular to a system for simulating the response of plant volatile organic compound emissions to environmental factors. Background Art

[0002] The production of plant volatile gases is mainly due to the co-evolution of plants and nature. On the one hand, the production of plant volatile gases is affected by the interference of insects, microorganisms and humans; on the other hand, plant volatile gases can inhibit insects and microorganisms and reduce their own damage. At present, the research on plant volatile gases is mostly carried out from the relationship between plants and insects and microorganisms, and chemical ecology with chemical action research as the core has been formed.

[0003] Plant volatile gases play an important role in the three-level nutritional relationship of plants, herbivorous insects and natural enemies, information transmission among plants and adaptive changes. The release of VOCs by plants is characterized by specificity, systemicity, timing and rhythmicity. VOCs mainly affect herbivorous insects in host selection behavior, oviposition behavior, courtship behavior, and attracting interference from insect natural enemies. The information transmission among plants mediated by VOCs includes four processes: synthesis and release of gases by "releaser" plants, transport of gases in the air, adsorption of gases on the plant surface and perception of gas signals by "receiver" plants.

[0004] Most of the existing responses of plant volatile organic compound emissions to environmental factors are mainly measured by detecting plant volatile organic compound emissions. However, parameters such as light, temperature and humidity, ozone and carbon dioxide are not easy to control, which can easily lead to inaccurate simulation of environmental factors for plant growth and thus inaccurate detection data.
