硒的生理功能及富硒水果的开发利用

硒是生态环境中一种十分重要的微量元素,它在植物、动物、人体中有重要的生理功能。本文综述了硒对植物的生长发育和果实品质的影响,它在植物生长过程中的抗氧化功能、参与蛋白质代谢及提高抗逆性的作用;硒在人体中的抗癌、防癌、预防心血管疾病、抗衰老及提高免疫力等方面的作用;水果中硒的含量、成分和赋存形态,果树累积硒的动态分布及与土壤的关系,提高水果含硒量的研究等。根据富硒水果开发的经济效益、存在的问题,提出进一步研究和开发的对策。

Physiologic Function of Selenium and Development Utilization of Rich Selenium Fruits

The selenium is one kind of extremely important trace element in ecological environment,it has the important physiological function in the plant,the animal,the human body.This article summarized the selenium's influence on plan's growth and fruit's character,it has functio'n of anti-oxidized,participated protein metabolism,enhanced adversity resistance in the plant growth process;selenium has function of anti-cancer,prevention cardiovascular disease,anti-senile and enhanced immunity in human body;selenium content,ingredient and shape In the fruit,dynamic distribution of accumulation selenium in fruit tree and its relations with the soil,research on enhancing selenium's contain in fruits and so on.According economic efficiency,existence questions in rich selenium fruit development,proposed further studies and development countermeasures.
