Effects of Different Auxin (IBA) Concentrations and Planting-Beds on Rooting Grape Cuttings (Vitis vinifera)
Aims: Vitis vinifera is a grape species and native to the Mediterranean region and east to northern Iran. The present research was carried out in greenhouse conditions to study the effects of four concentrations of indole-3-butyric acid (IBA) (0; 2000; 4000; and 6000 mg/l) and three planting beds (agricultural soils, sandy, and mixture of agricultural soils and sand) on rooting grape cuttings i...
متن کاملPolyphenol Oxidase Activity during Rooting in Cuttings of Grape (Vitis vinifera L.) Varieties
Polyphenol oxidase (PPO) activity was investigated during rooting in cuttings from three different grape cultivars (Vitis vinifera L. cvs. Muscat, Cardinal and Perlelte), and the enzyme activity and rooting ability were compared. Rooting was observed on the Muscat and Perlelte cuttings, but not on the Cardinal cuttings. PPO activity started to increase in the early stage of the experiment, and ...
متن کاملEffects of shoot-applied gibberellin/gibberellin-biosynthesis inhibitors on root growth and expression of gibberellin biosynthesis genes in Arabidopsis thaliana
To elucidate the involvement of gibberellin (GA) in the growth regulation of Arabidopsis roots, effects of shoot-applied GA and GA-biosynthesis inhibitors on the root were examined. Applying GA to the shoot of Arabidopsis slightly enhanced the primary root elongation. Treating shoots with uniconazole, a GA biosynthesis inhibitor, also resulted in enhancement of primary root elongation, while sh...
متن کاملGenetic variation in rooting ability of loblolly pine cuttings: effects of auxin and family on rooting by hypocotyl cuttings.
After about 20 days, hypocotyl cuttings from 20-day-old loblolly pine (Pinus taeda L.) seedlings rooted easily in the presence of the auxin indole-3-butyric acid (IBA), with roots forming directly from xylem parenchyma. In contrast, woody cuttings from 1-2-year-old hedged seedlings formed roots indirectly from callus tissue in 60-90 days, but IBA had little effect on rooting. Variation in rooti...
متن کاملIncreased Production and Activity of Cellulase Enzyme of Trichoderma reesei by Using Gibberellin Hormone
Cellulolytic complex are enzymes capable of hydrolyzing cellulose. Due to rapid growth in population and industrialization, most countries are required to produce more fuel. Production of bioethanol from lignocellulosic biomass is very challenging due to environmental pollution by fossil fuels. Cellulases play a significant role in biotechnological processes. The cost of production of cellulase...
