Abstract Isothiocyanates, monoterpenes, and leaf volatiles that are components of essential oils induce the expression of heat shock protein genes in plant systems. Here, the modes of heat shock responses induced by the essential oil compounds and their heat-tolerance-enhancing activities are described. Traditionally, green manure produced from essential-oil-containing plants has been used because such manure is thought to have beneficial effects in fertilizing, allelopathic, antibacterial, and animal-repellent activities. In addition to these effects, stress (especially heat stress)-tolerance-enhancing activities can be expected. Biostimulants containing such essential oils may be able to maintain the yield and quality of crops under increasing ambient temperatures. In this review, chemicals that enhance the heat tolerance of plants are designated as heat tolerance enhancers (HTLEs). Some essential oil compounds can be categorized as HTLEs available for biostimulants.

精油在提高植物耐热性方面的潜在用途

摘要 作为精油成分的异硫氰酸酯、单萜和叶挥发物可诱导植物系统中热休克蛋白基因的表达。在这里，描述了由精油化合物引起的热休克反应模式及其耐热性增强活动。传统上，一直使用由含精油植物生产的绿肥，因为这种肥料被认为在施肥、化感作用、抗菌和驱赶动物方面具有有益作用。除了这些影响之外，还可以预期压力（尤其是热压力）耐受性增强活动。含有此类精油的生物刺激剂可能能够在环境温度升高的情况下保持作物的产量和质量。在这次审查中，增强植物耐热性的化学物质被称为耐热性增强剂 (HTLE)。一些精油化合物可归类为可用于生物刺激素的 HTLE。
