矿质元素和植物体内乙烯形成的关系

乙烯是植物体内五大激素之一,是植物生长、发育和繁殖过程中的重要调节物质,而矿质元素对其形成过程存在影响。一些元素如硫是乙烯合成前体内的组成成分;一些元素如铁、钴等作为乙烯合成途径中酶的辅基或抑制剂影响酶的活性从而调节乙烯合成;而另一些元素如铜、锌等则是通过脂质氧化形成乙烯的途径影响乙烯的生成,本文论述了矿质元素和乙烯形成天系方面的最近研究进展。

RELATIONSHIP BETWEEN MINERAL ELEMENTS AND SYNTHESIS OF EIHYLENE

Ethylene, one of the phtohormones, is an important regulater in plant growth, development and germination. Mineral elements have different effects on the synthesis of ethylene. Some elements are components of the precursors on ethylene synthesis, as S; some influence the activities of enzymes in ethylene synthesis passway as cofactors of these enzymes, as Fe, Co; others interfere with the ethylene prodution through the lipid peroxidation, as Cu, Zn, etc.. This paper describe the current advances in the relationship between mineral elements and synthesis of ethylene.
