A method, using bunches from pre-rooted cuttings which are defoliated very early during bud burst, allows the cultivation of fruiting plants in the glasshouse. The germinability of the seeds obtained in this way is improved, which permits, in particular, progenies of an early mutant of the cultivar "Cot", the seeds of which obtained in the field do practically never germinate.
Une technique pour améliorer la germinabilité des graines de vigne pour les besoins
de l'amélioration
Une technique, consistant à obtenir des grappes sur des boutures préenracinées puis soumises à un effeuillage très précoce au débourrement, permet de cultiver des plantes fructifères en serre. Les graines ainsi obtenues ont une proportion de germination meilleure, ce qui a permis en particulier d'obtenir des descendants d'un mutant précoce du Cot dont les graines obtenues au champ ne germent pratiquement jamais.
