Phaseolus vulgaris L. plants were supplied through the root with [8-(14)C]benzylaminopurine ([(14)C]BA). Collections of root, apex, and leaves were made 8 and 48 hours after labeling; ethanolic extracts of tissues were purified and subjected to thin layer chromatography on silica gel and/or cellulose powder.From [(14)C]BA at least two different metabolites originate, the BA riboside and ribotid...

Wheat yield is largely determined during the period prior to flowering, when the final numbers of fertile florets and grains per spike are established. The aim of this study was to assess the dynamics of floret primordia development in winter wheat in response to pre-anthesis application of a synthetic cytokinin, 6-benzylaminopurine (6-BA). We conducted an experiment in which two foliar spray t...

Embryogenic cultures of Picea balfouriana, which is an important commercial species for reforestation in Southern China, easily lose their embryogenic ability during long-term culture. Embryogenic tissue that proliferated at lower concentrations (3.6 μM and 2.5 μM) of 6-benzylaminopurine (6-BAP) were more productive, and generated 113 ± 6 and 89 ± 3 mature embryos per 100 mg embryogenic tissue,...

Purpose. To optimize the method of clonal micropropagation rocket (Eruca sativa Mill.). Methods. Seeds cultivars 'Znahar' and 'Lybid' were used for introduction into in vitro culture. Solutions sodium hypochlorite (35%), ethanol (70%) HgCl2 (0.2%) sterilization. A 5% solution chloramine served as a control. Sterile material was planted on liquid solid agar nutrient media according to Murashige-...

To improve the efficiency of chromium (Cr) phytoextraction by Leersia hexandra Swartz, effects mowing on Cr accumulation in L. were investigated using hydroponic experiments. Mowing heights (0, 5, and 10 cm), interval (30, 60, 90 120 days), frequencies (1, 2, 3 times) optimized. at cm above roots significantly increased shoot biomass (32.9 g/pot). The days achieved highest (62.8 with thrice (67...

periwinkle (vinca minor l.) is an evergreen perennial herbaceous plant that belongs to the family apocynaceae. the aerial part of this plant contains certain alkaloids such as vincamine, isovincamine and vincine. the most important of these is vincamine that re-duces blood pressure and promotes memory and the ability for mental concentration. mi-cropropagation could be a good alternative for th...
