In the plant regeneration process, a great deal of variability is observable between different varieties and genotypes. Even within the same genotype, there are differences in the intensity of this process. New biologically active substances are currently being tested to increase the effectiveness of regeneration in plants. Among them are zearelonene (ZEN) – a substance obtained from an extract...

An efficient in vitro method for multiple shoot bud induction and regeneration has been developed in Artemisia annua L. using leaf and stem explants in various concentrations and combinations of plant growth regulators to evaluate the frequency of regeneration. The sources of explants as well as plant growth regulators in the medium were found to influence the multiple shoot induction. The resu...

This study was conducted to investigate the effect of treatment conditions plant growth regulators on marketability ‘Red Dream’, a triploid grape. In order achieve purpose this study, gibberellic acid 3 (GA3) 100 ppm single use group set as control group. addition, fruit characteristics expressed when cytokinins such thidiazuron (TDZ) or forchlorfenuron (CPPU) 2.5 5.0 mixed with GA3 were compar...

The effects o f thidiazuron (TDZ) on adventitious shoot bud formation from leaf and peti­ ole explants excised from in-vitro-grown plantlets o f a begonia were tested by a two-step procedure: a short exposure (5 to 120 min) to 40 pM TDZ in liquid MS medium followed by culture on agar-solidified MS medium without growth regulators. Exposure of explains for five min to TDZ induced bud formation, ...
