Abstract
The present work was carried out during the two successive seasons of 2010 and 2011 in the shade house of the Viticulture Department, Horticulture Research Institute, in Giza, Agric. Res. Center, Ministry of Agriculture. The used cuttings were taken from mother Dogridge vines grown in the private farm at 58 Km Cairo - Alex. desert road. Hard-wood cuttings were taken in Jan. from moderately vigorous 1-year-old canes, each cutting comprised three nodes (eyes) and was about 30-35 cm long. The cuttings were stored with their basis upwards in the shade house until planting on 15 Feb. in both seasons Henna extracts obtained from the crushed dried leaves of Lawsonia inermis L. 200 gm Henna was immerged in one liter for 48 hours in one of the following solvents:- tap water, boiled water, ethyl alcohol, hexane, acetone and petroleum ether. The used concentration from henna crude extracts by different solvents was 3gm/ l of distilled water (i.e.3000 ppm). Cuttings were soaked in each of the considered extracts for 24 hours before planting. In addition, the recommended application of the growth regulator IBA at (1000 ppm) by dipping for 10 seconds was used as a control. The best results were obtained by henna extracted by acetone and tap water solvent without significant differences among them. While, untreated cuttings gave the lowest results followed by cuttings treated by ethyl alcohol extract and than IBA treatment. The other henna extractions were ranged between them. Generally, it is possible to improve rootapility of Dogridge grape rootstock cuttings by soaking cutting basis in henna extracted by acetone or tap water solvents which gave nearly similar effect, but use of tap water solvent, is more economic and easier for application.
