摘  要：
为了了解生长素对植物不同器官的影响及调控作用,本研究总结了近年来生长素在植物根、茎、叶、花、果实和种子生长发育方面的研究进展。主要包括:生长素可以促进植物侧根和不定根的发生及生长;促进细胞分裂、伸展和分化进而促进植物茎的伸长;促进花芽萌发及影响花的形态建成和衰老;促进果实的发育和单性结实,影响果实增大和果实成熟;促进光合产物的积累,影响种子胚的形成等。除此之外还对生长素运输的生理特点、运输机制和信号转导机制等进行了梳理,了解了生长素在植物体内的调节作用主要表现在顶端优势、组织分化、器官形成、向性反应、形态建成等方面。同时还提出了生长素在网络信号调控和各器官量的分配方面研究的不足,以期为日后进一步研究提供参考。

摘  要：
To understand the effect and regulatory role of auxin on different organs of plants, this study summarizes the research progress of auxin in the growth and development of plant roots, stems, leaves, flowers,fruits and seeds in recent years. Auxin could promote the germination and growth of lateral roots and adventitious roots of plants; the cell division, extension and differentiation to boost the elongation of plantstems; and the flower bud germination; affect the morphogenesis and senescence of flowers; enhance fruitdevelopment and parthenocarpy and influence fruit enlargement and fruit ripening; improve the accumulationof photosynthetic product and affect the formation of seed embryos. In addition, the physiologicalcharacteristics, transport mechanisms, and signal transduction mechanisms of auxin transport were also reviewed. The regulation of auxin in plants was mainly manifested in apical dominance, tissue differentiation,organ formation, tropic reaction, morphogenesis and other aspects. At the same time, the deficiencies of auxinin the regulation of network signals and the allocation of various organs were also pointed out, in order to provide references for further research.
