Rosa hybrida lacks violet to blue flower varieties due to the absence of delphinidin-based anthocyanins, usually the major constituents of violet and blue flowers, because roses do not possess flavonoid 3',5'-hydoxylase (F3'5'H), a key enzyme for delphinidin biosynthesis. Other factors such as the presence of co-pigments and the vacuolar pH als...
Aim: To detect the induction of morphological and populational alterations on Ceriodaphnia cornuta concerning cyclomorphosis and population dynamic parameters as densities, fecundity rates, juveniles percentage, males presence and ephippia presence in the presence of predators; Methods: Two experiments were performed: Experiments with fishes fed on Ceriodaphnia cornuta – Experiment 1 – and “Fis...
In this study a trial was performed to determine the effect of a combination of two aqueous extracts of two medicinal plants namely the violet, Viola odorata, and the rue, Ruta graveolens, with concentrations of 0.15625, 0.3125, 10-20 mg/cm3 on the growth of Trichomonas vaginalis cultured in (CM161) medium during periods of 24, 48, 72, and 96 hrs.
