Influencia de la concentración de sacarosa en el medio, sobre la respuesta de material de vid "in vitro"

Abstract

[ES]: Se estudia el efecto de dos concentraciones (20 y 30 gl(elevado a -1)) de sacarosa en el medio de cultivo, sobre el desarrollo in vitro de los portainjertos de vid 41B, 110 de ichter,) 96-17, 161-49 de Couderc y Rupestris de Lot, del cultivar Superior y de los clones CH-) y CH-2 procedentes de Chile. El medio con la concentración mas baja de sacarosa favoreció, en general el crecimiento de la parte aérea del material de vid in vitro, en especial de las variedades 161-49, Rupestris de Lot, Superior y 196-17. Este mayor crecimiento de la parte aérea del explanto (órganos con clorofila), no se produjo en el sistema radical, cuyo desarrollo fue independiente de la concentración de azúcar en el medio y mas relacionable con la variedad de vid. El medio con 20 gl(elevado a -1) de sacarosa también mostró una ligera mayor predisposición a.la vitrificacón del material vegetal in vitro.

[EN]: The effects of two sucrose amounts, 20 and 30 gl(elevado a -1), added to the nutrient medium on the in vitro development of grapevine rootstocks 4 lB, 110 Richter, 196-17, 161-49 de Couderc and Rupestris de Lot, of Superior cultivar and of CH-I ,and CH-2 clones from Chile was studied. Medium with the lowest amount of sucrose favoured the aerial part growth of varieties ) 61-49, Rupestris de Lot, Superior and 196-17. This major growth of aerial part of explant (organs with clhorophyll), did not produce it in radical system. Development of this system was independent of sugar concentration in substrat and more in relation with grape variety Substrat with 20 gl(elevado a -1) of sucrose also shown a light major inclination to vitrification of in vitro plant. material
