This study was conducted to determine to find out how long the grapevine cuttings of rootstock 41B should be submerged in order to increase adventitious root formation. The cuttings were placed in a big container filled with tap water in an order of 72, 48, 24 and 12 hours. Data obtained showed that generally water soaking increases rooting of the cuttings. Auxin applied afterwards also has a positive effect on inducing rooting. Keeping the cuttings submerged in water at least 24 hours and applying IBA afterwards resulted in the best results. Water soaking and/or IBA, however, did not improve the top growth of the cuttings.
