Induction of somatic embryogenesis using side chain and ring modified forms of phenoxy Acid growth regulators.
The induction of somatic embryo development in cell cultures of alfalfa (Medicago sativa), celery (Apium graveolens), and lettuce (Lactuca sativa) was compared for 2,4-dichlorophenoxy-acetic acid (2,4-D) and various phenoxy acid growth regulators. Tests using a series of straight chain extensions to the phenoxy acid side chain indicate that phenoxybutanoic acid is active, whereas the phenoxypro...
متن کاملKinetics Properties of Guaiacol Peroxidase Activity in Crocus sativus L. Corm during Rooting
Guaiacol peroxidases (GP) are haem-containing enzymes participating in many physiological processes in plants. The expression pattern of these enzymes is organ-specific and developmentally regulated. Methods: The presence of GP activity in extract samples, prepared from Crocus sativus L. corms that were either dormant or rooting for 3, 6 and 10 days, was investigated. Results: Kinetic studies r...
متن کاملPurification and Kinetic Properties of Guaiacol Peroxidase in Turnip (Brassica napus var. okapi) Root During Different Growth Stages
In this study, we present changes of peroxidase (E. C. 1.11.1. 7) activities in the root of Brassica napus var. Okapi during rosette stage until ripening of the fruits. Peroxidase activity was determined seasonally over an eight month period. Results showed that total peroxidase activity in the root was highest in mid June and the lowest activities were observed from time of winter dormancy unt...

optimization of regeneration methods in cotton is necessary to improve and successful production of transgenic cotton cultivars by tissue culture technique. this study was conducted to determine the genotypic effect on callus induction in cotton using 3 genotypes (coker349, 4-s-4 and c1211) and coker 312 selected and a study was carried out in cotton research institute of gorgan using a factori...
متن کاملSomatic embryogenesis and bulblet production in Narcissus papyraceus cv. Shirazi: effect of plant growth regulators, light intensity, sucrose concentration, methyl jasmonate and anti-gibberellins
Generally, narcissus is propagated through vegetative methods, but due to their low yield their are not economical. This study was conducted to develop a suitable method for the production of somatic embryos and bulblets in Narcissus papyraceus cv. Shirazi. Bulb scales were placed on the MS medium supplemented with 2,4-D and BAP each at 0.0, 0.25, 0.5 or 1 mg/l concentrations to form somatic em...
