Název v původním jazyce

The impact of some plant hormones on the metabolism of proline in wheat

Popis výsledku v původním jazyce

This paper reports the results of experiments in investigating the effect of 24-epibrassinolide (24-epi) and cytokinin (benzylaminopurine-BAP) on the activity of glutamate kinase (EC 2.7.2.11), chlorophyll and proline content in leaves of spring wheat. Proline plays an important role in plants in the regulation of their metabolism during stresses. The experiments were carried out in field and the preparations were applied in a spray in concentration 10-6 M. The enzyme glutamate kinase (GK) starts the biosynthesis of proline from glutamate and its activity was determined by the modified hydroxamate method1,2. Chlorophyll content was assessed spectrophotometrically from acetonic extract. The activity of GK grew up to 132.5 % (24-epi) and 181.5 % (BAP) incomparison with the control plants. Both preparations have stimulating effect on the chlorophyll content. Amino acid analysis of plant extracts was carried out by AccQ*Tag method3. HPLC system with a fluorescence detection was used in th
