本试验以塑料大棚中栽植的草莓（索菲亚）为试材，采用不同浓度的ＧＡ３（５、１０、１５ｍｇ／Ｌ）于休眠期处理，研究其对草莓生长发育的影响。结果表明：三种不同浓度的ＧＡ３均可及时终止草莓休眠过程，提早物候期，促进植株的生长发育，提高产量，尤以１０ｍｇ／Ｌ处理的综合效果好，而１５ｍｇ／Ｌ处理的促进植株营养生长的效果好。但各处理对果实品质未产生明显影响。该项研究对草莓的产业化生产有一定的指导意义 Strawberry (Sofia) planted in a plastic greenhouse was used as experimental material to study the effects of different concentrations of GA3 (5, 10, 15 mg / L) on the growth and development of strawberry. The results showed that three different concentrations of GA3 could terminate strawberry dormancy in time and promote the growth and development of plants at earlier phenophase, especially at the concentration of 10 mg / L, while the effect of 15 mg / L on plant nutrition Good effect of growth. However, the treatments did not have any significant effect on the fruit quality. This research has certain guiding significance to the industrialized production of strawberry
