摘要
综述了国内外经济林霜冻害研究进展,包括霜冻害对经济林的危害、霜冻害表现及霜冻害发生的生理生化机制,这些机制包括细胞膜透性、有毒物质积累、保护酶系统、非酶系统、离子变化、内含物质变化、基因表达等;并提出了今后经济林霜冻研究值得深入探讨的问题。
Frost is the phenomenon that young parts of economic forest tree damaged by low temperature during the growth period at night when the temperature of soil and tree surface is reduced to 0℃or below 0℃in short time.Frost is a common meteorological disaster,and causes great losses to the economic forest production every year.The article reviews the research progress of the domestic and foreign research on economic forest,including the frost injury to economic forest,frost performance and the physiological and biochemical mechanism of frost injury.These mechanisms include cell membrane permeability,accumulation of toxic substance,protective enzyme system,non-enzymatic system,ionic changes,the material contents,gene expression,etc.And some problems put forward are worthy of further discussion on frost of economic forest.
