摘　　要：陆生植物进化出高度的形态可塑性,使其通过响应各种环境刺激的向性生长(tropic growth)来补偿其运动性的缺乏。向水性(hydrotropism)是植物根系在土壤中寻找水分的生物学特性,有助于植物适应不断变化的水势条件。综述了脱落酸(abscisic acid,ABA)、细胞分裂素(cytokinin,CK)和生长素(auxin)在根系向水性中的最新研究进展,并讨论了其中存在的和新出现的问题,以期增进对植物根系处理、调节和整合植物生长,以及响应水分刺激信号的认识。Terrestrial plants have evolved remarkable morphological plasticity that enables them to compensate for their lack of motility by directional growth in response to various environmental stimuli.Hydrotropism allows roots to forage for water in the soil,a process known to facilitate plant adaptation to continuously changing water availability.This paper reviews the latest research progress on abscisic acid,cytokinins,and auxins in root hydration,and discusses existing issues.In order to enhance the understanding of plant root treatment,regulation,and integration of plant growth,as well as response to water stimulation signals.
