摘要:

自19世纪末吲哚乙酸在植物中被发现以来备受关注,吲哚乙酸能够促进细胞生长和分化,影响植株的根、茎、叶、果实,其应用领域十分广泛,近年来在农业、林业等各个方面取得了显著的研究成果。文章综述了微生物中吲哚乙酸的合成途径,影响微生物合成吲哚乙酸的因素,以及微生物合成吲哚乙酸对植物的作用等的研究情况。结合当今严峻的环境污染形势,合理使用微生物制剂能够降低化学肥料等对土壤、空气和地下水的污染,为可持续发展提供有效方法。总结并展望微生物合成吲哚乙酸在林木上应用的发展优势和潜力,为得到应用广泛且高效、对环境友好污染小的微生物制剂提供依据。

Abstract:

Since the discovery of indole-3-acetic acid in plants at the end of the 19th century, it has received much attention, indole-3-acetic acid can promote cell growth and differentiation,affect the roots, stems, leaves, and fruits of plants,it has a wide range of applications and has achieved significant research results in various fields such as agriculture and forestry in recent years. This article reviewed the synthesis pathways of indole-3-acetic acid in microorganisms, factors affecting microbial synthesis of indole-3-acetic acid, and the effects of microbial synthesis of indole-3-acetic acid on plants.Considering the current severe environmental pollution situation, the rational use of microbial agents can reduce the pollution of soil, air, and groundwater caused by chemical fertilizers, providing effective methods for sustainable development. The development advantages and potential of microbial synthesis of indole-3-acetic acid in forest applications were summarized and prospected, providing a basis for the improvement of microbial preparations that are widely used, efficient and environmentally friendly microbial preparations with little pollution.

Key words: indole-3-acetic acid, plant-growth-promoting rhizobacteria, growth promotion, application
