Effect of Antioxidants, Amino Acids and Plant Growth Regulators on in vitro Propagation of Rosa centifolia
Background: Rosa centifoliais commercially propagated by asexual means but in vitro propagation ensure the production of disease free and healthy plants and browning of explants creates hurdle in their multiplication. Objectives: The aim was to reduce oxidative browning of shoots of R. centifolia in MS medium during in vitro propagation. Materials and Methods: Axillary buds of R. centifolia we...
متن کاملPlant Growth Regulators II: Cytokinins, their Analogues and Antagonists
Hormones in plants differ from most of those in animals by having pleiotropic effects; that is, they are involved in the control of a wide range of developmental processes. At the same time the effect of a hormone on any developmental process depends on the species. For example, ethylene inhibits growth in dicotyledons and most monocotyledons but is promotory in deepwater rice and other hydroph...
متن کاملPlant Growth Regulators
Plant growth regulators are hormone-like chemicals that occur naturally in plants, and play a central role in their growth and development. Five major classes of plant growth regulators have been identified as plant hormones, but scientists believe that there are more waiting to be discovered. The five growth hormones include auxins, gibberellins, cytokinins, abscisic acid, and ethylene. Collec...
متن کاملResponse of Germination and Seedling Growth of Pepper cultivars to Seed Priming by Plant Growth Regulators
In order to study the germination and growth of pepper seeds, a factorial experiment based on a completely randomized design with three replications was conducted. The first factor was consisting of five cultivars of pepper (Marquiza, Cadia, California Wonder, California Wonder 310 and California Wonder 300) and the second factor was gibberellic acid with three levels (0 as control, 250 and 500...
متن کاملBeijerinckia derxii releases plant growth regulators and amino acids in synthetic media independent of nitrogenase activity.
AIMS This study aims at evaluating the ability of Beijerinckia derxii, a free-living nitrogen (N)-fixing bacterium frequently isolated from tropical soils, to release certain plant growth regulators [indoleacetic acid (IAA), ethylene, polyamines] and amino acids into the growth medium. METHODS AND RESULTS The production of those substances was compared using both cultures in which nitrogenase...
