Root And Shoot Growth Of Grapevine (Vitis Vinifera L.) Cuttings As Affected By Rooting Media And Varieties

Abstract:

Investigations were carried out at the Institute for Agricultural Research farm, Samaru, Zaria during the 1992 dry season to determine the effect of rooting media on root and shoot growth of varieties of grapevine (Vit is vinifera L.). Three experiment were conducted using fresh, 3 and 6 weeks callused cuttings . Treatmnts consisted of seven rooting media as main-treatments and eleven varieties of grapevine as subtreatments laid out in a split plot design replicated six times. In all the three experiments Anab x American seedling was observed to have an edge over all the other varieties tested with respect to apical and basal shoot length, shoot fresh and dry weights, number of leaves per cutting. Leave area number of roots, root volume, root fresh and dry weights and basal shoot girth among among other vegetative characters studied. In the rooting media treatment, the rooting media, potting mixture III (75% sand, 12.5% FYM, 12.5% Topsoil) 100% ricehull and potting mixture II (50% sand, 25% FYM, 25% Topsoil) resulted in the best performance in fresh, 3 and 6 weeks callus cuttings respectively.
