摘 要:[目的]了解不同树形对不同台湾青枣品种果实外观、内在品质和产量的影响。[方法]用游标卡尺测定果实纵横径,用手持式折光仪测定可溶性固形物含量,用靛蓝染色法测定果实V_(C)含量,用酸碱滴定法测定果实可滴定酸含量。[结果]脆蜜不同树形对果实纵径、横径、果形指数、可滴定酸含量、可溶性固形物和单果重均不产生显著影响,但显著影响果实V_(C)含量、单株产量和树冠枝叶总重;高朗1号则只有单株产量受树形影响显著,其他均不受影响。[结论]脆蜜受树形的影响大于高朗1号。3种树形中,脆蜜最适合棕榈叶形,其次是纺锤形和开心形;高朗1号最适合纺锤形,其次是开心形和棕榈叶形。[Objective]The effects of tree shape on fruit appearance,internal quality and crown of different Zizyphus mauritana Lam.varieties were studied.[Method]Vemier caliper was used to measure longitudinal diameter and transverse diameter of fruits.Hand refractometer was used to measure the content of soluble solid(TSS).Indigo dyeing was used to measure the content of vitamin C(V_(C))in fruits.Acid base method was used to measure the content of titratable acidity in fruits.[Result]To Cuimi,tree shape had insignificant impact on longitudinal diameter and transverse diameter,fruit shape index,content of titratable acidity,TSS and weight per fruit,while had significant impact on the content of V_(C),yield of per plant and weight of crown.To Gaolang No.1,only yield per plant was significantly influenced by tree shape.[Conclusion]Tree shape had more effect on Cuimi than Gaolang No.1.The most suitable tree shape of Cuimi was plam,spindle and open followed.The most suitable tree shape of Gaolang No.1 was spindle,open and plam followed.
