摘　　要：为了探究外源肌醇对草莓生长和品质的影响,以红颜草莓为试材,对草莓进行外源肌醇处理,通过测定草莓株高、糖含量和果实单株产量指标,比较常规与肌醇处理情况下草莓的生长状况。结果表明:外源肌醇对采摘后期草莓植株长势具有一定促进作用,能在一定程度上促进草莓植株根系的生长发育,增加叶面积;在采摘后期,草莓株高及冠径分别较对照提高了15.76%、45.52%;在草莓全生育期内,外源肌醇能在一定程度上提高草莓的糖含量和产量,还能够显著增加草莓单株鲜质量,较对照提高了122.21%,采摘初期至采摘盛期1个月内采摘产量较对照提高了28.88%;在采摘后期,单果质量、单株产量和折合产量与对照相比均存在极显著差异,分别较对照提高106.54%、100%、84.29%,增产效果十分明显。综上,外源肌醇可以促进草莓植株的生长,提高草莓的品质,还能在一定程度上提高其产量。In order to explore the effects of exogenous inositol on the growth and quality of strawberry under low temperature stress,this experiment took Red Yan strawberry as the test material,and treated strawberry with exogenous inositol.By measuring strawberry plant height,sugar content and fruit yield per plant indicators,the growth status of strawberry under conventional and inositol treatment was compared.The results showed that exogenous inositol had a certain effect on the growth of strawberry plants in the late picking period,and could promote the root growth and development of strawberry plants and increase the leaf area to some extent.The plant height and crown diameter of strawberry were increased by 15.76%and 45.52%,respectively.During the whole growth period of strawberry,exogenous inositol could improve the sugar content and yield of strawberry to a certain extent,and also significantly increase the fresh weight per plant,which was 122.21%higher than that of the control,and the harvest yield was 28.88%higher than that of the control within one month from the early picking period to the peak picking period.In the late picking period,there were significant differences in fruit weight,yield per plant and reduced yield,which were increased by 106.54%,100%and 84.29%,respectively,compared with the control.In conclusion,exogenous inositol can promote the growth of strawberry plants in the late picking period,improve the quality of strawberry and also increase its yield to a certain extent.
