摘要(Abstract):

核桃是世界上著名干果,也是优质硬阔木材树种,主要分布在干旱、半干旱、湿润、半湿润地区,均会受到不同干旱程度的影响。干旱作为一种水分胁迫,对植物的影响主要表现在生长发育及其生理代谢过程。本文系统的综述了国内外关于核桃在干旱条件下核桃形态结构、组织水分状况、质膜系统、渗透调节物质和保护酶系统的变化情况,以期对筛选和培育抗旱高产的核桃品种,对核桃产业的可持续发展提供理论依据。干旱是植物经常遭受的一种逆境,全世界干旱、半干旱地区占全球的43%,在湿润、半湿润地区有时也会出现一定程度的夏旱。干旱对经济林的影响非常大,特别是在干旱胁迫下,对核桃的生长、产量以及坚果质量都有较大影响。为了了解不同核桃品种的抗旱能力,需要了解核桃在干旱条件下生理生化响应,探索机制。筛选和培育抗旱高产的核桃品种,对核桃产业的可持续发展提供理论依据。
The walnut was one of the world's famous dried fruits. also a hardwood species with high quality. It was mainly distributed in arid,semi-arid,humid and semi-humid areas,and affected by different degrees of drought. Drought,as a water stress,impacted on plants mainly in the growth,development and physiological metabolic process. Native and foreign researches were systematically reviewed in the changes of walnut morphology,tissue water status,plasma membrane system,osmotic adjustment substances and protective enzyme system under drought conditions. In order to provide a theoretical basis for screening and breeding of drought-resistant and high-yield varieties of walnuts,and the sustainable development of walnut industry. Drought was an adversity that plants often suffered,the world's arid and semi-arid regions accounted for 43% of the world's total area,and sometimes there would be a certain degree of summer drought in the humid and semi humid areas. The impact of drought on economic forests was very large,especially on the growth,yield and quality of nuts. In order to acquaint the different varieties of walnut drought resistance,it was necessary to understand the physiological and biochemical response of the walnuts in drought conditions,and to explore the mechanism. It could provide a theoretical basis for sustainable development of walnut industry to screen and breed drought-resistant high-yield varieties of the walnut.
