Abstract

Abstract: To investigate the regulatory effects of sucrose （Suc） and indole-3-acetic acid （IAA） on rhizome development of kentucky bluegrass （Poa pratensis L. var. anceps）， this study used ‘Qinghai’ as the experimental material to analyze the impacts of Suc and IAA on early rhizome sucrose metabolism and hormone contents. The results showed that both exogenous Suc and IAA promoted early rhizome development， but their mechanisms of action differed. Suc treatment could promote IAA synthesis or transport， increase IAA content in rhizomes， thereby enhancing sucrose absorption， activating the activities of sucrose decomposition-related enzymes， and this process was accompanied by starch accumulation. In contrast， IAA treatment could increase endogenous IAA content to promote sucrose transport to rhizomes， raise the activities of sucrose and starch decomposition enzymes， accelerate the decomposition of sucrose and starch， and inhibit starch accumulation， thus facilitating rhizome development. Notably， Suc and IAA exhibited a synergistic effect during sucrose accumulation， while showing an antagonistic effect during starch accumulation.

Key words: Poa pratensis L. var. anceps ‘Qinghai’, Rhizome, Sucrose, Indole-3-acetic acid, Carbon metabolism, Endogenous hormone

摘要： 为探究蔗糖（Sucrose， Suc）和吲哚乙酸（Indole-3-acetic acid， IAA）对青海扁茎早熟禾（Poa pratensis L. var. anceps ‘Qinghai’）根茎发育的调控作用，本试验以青海扁茎早熟禾为材料，分析蔗糖和IAA对根茎早期蔗糖代谢和激素含量的影响。结果表明：外源蔗糖和IAA均能促进根茎早期发育，但作用机制存在差异。Suc处理可以促进IAA合成或运输，增加根茎IAA含量，从而增强对蔗糖的吸收，激活蔗糖分解相关酶活性同时伴随着淀粉的积累；IAA处理可以增加内源IAA含量，促进蔗糖向根茎运输，并增加了蔗糖和淀粉分解酶活性，加速蔗糖和淀粉的分解，抑制淀粉积累，从而促进根茎发育。值得注意的是，Suc与IAA在蔗糖的积累过程中表现出协同作用，但在淀粉积累过程中则呈现拮抗作用。
