Abstract

Mediante aplicaciones de 6-(bencilamino)-9-(tetrahydropyran-2-y1)-9H-purina (Kinina SD 8339) a 10D0ppm, consegui el cambio de sexo de vides masculinas a hermafroditas en la totalidad de las flores tratadas.
Las apllcaciones se realizaron sobre Aramon X Rupestris Ganzin no 1, 3306 C (V. riparia X V. rupestris), 3309 C (V. riparia X V. rupestris), 110 R (V. berlandieri X V. rupestris), 420 A (V. berlandieri X V. riparia), 34 E. M. (V. berlandieri X V. riparia), "Anf." (anfidiploide de V. vinifera X V. rotundifolia) y "Gibi X Anf. no 1" (retrocruza del anterior X V. vinifera). Luego del cambio de sexo, se produjo una paralización del desarrollo de las flores y un posterior desecamiento del racimo. Solamente se consiguió llegar hasta la madurez de las bayas en dos racimos de Aramon X Rupestris Ganzin no 1 que recibieron un único tratamiento con SD 8339 a 1000 ppm.
