赣南秋冬茬番茄砧木筛选

Selection of Tomato Rootstocks in Autumn and Winter in Gannan Region

  • 摘要: 采用"勇士二号""强力""久绿787""千叶""格林沃德"5个砧木品种分别与"舒伯特"进行嫁接,以"舒伯特"自根苗为对照(CK),研究不同砧木嫁接对赣南地区秋冬茬番茄生长、产量及抗性的影响,筛选出适合赣南地区应用推广的砧木品种。结果表明:不同品种砧木嫁接在产量、青枯病抗性方面均有不同程度的提高,并且对果形及可溶性固形物含量等品质性状影响不大;"勇士二号""格林沃德"在植株长势、抗病性、商品果率、产量等方面明显高于CK,分别较CK增产37.6%、28.9%,可作为赣南地区秋冬茬番茄嫁接栽培优先选用的砧木品种。

     

    Abstract: Five rootstock varieties of‘Warrior 2’‘Qiangli’‘Evergreen 787’‘Chiba’‘Greenwood’were grafted with‘Schubert’respectively.‘Schubert’self-rooted seedlings were used as the control(CK)to study the grafting effects of different rootstocks in Gannan region.Based on the influence of tomato growth,yield and resistance in autumn and winter in the region,the rootstock varieties suitable for application and promotion in Gannan region were selected.The results showed that the grafting of different varieties of rootstocks had different degrees of improvement in yield and bacterial wilt resistance,and had no obvious impact on quality traits such as fruit shape and soluble solid content.‘Warrior 2’and‘Greenwood’had improved plant growth,disease resistance,commercial fruit rate,yield,etc.were significantly higher than CK,and the yield was 37.6%and 28.9% higher than that of CK.It can be used as the preferred rootstock for tomato grafting cultivation in autumn and winter in Gannan region.
