摘　　要：优质的牧草种子是草业与畜牧业健康发展的物资保障。植物生长调节剂的推广使用为提高牧草种子产量开辟了新的途径。依据其作用效果,植物生长调节剂可以分为植物生长促进剂与植物生长抑制剂两大类,目前以后者在牧草种子生产中的应用最为广泛。本文结合国内外研究进展,就两大类植物生长调节剂在牧草种子生产中的应用与作用机理进行了总结,重点论述了其对种子产量以及产量构成因素的影响,并总结了目前研究中存在的问题,提出了相应的研究展望。High quality forage seeds are the foundation of good pastures for the livestock husbandry industry. The advent of plant growth regulators （PGRs） has created new methods for increasing seed production in grasses and legumes. Based on their effects, PGRs can be divided into two types： plant growth stimulators and plant growth inhibitors. Plant growth inhibitors have been widely used in forage seed production. This research detailed progress in the use and mechanism of PGRs for forage seed production. In particular, it illuminated the effect of PGRs on seed yield and seed yield components. Existing problems and developmental trends were also summarized to provide necessary information to improve future research.
