Abstract
Grape (Vitis vinifera L.) is an important fruit crop and is widely cultivated because of its nutritional and economical values. The foliar application of nutrients improves the performance and quality of grapes, and silicon is recently classified as an essential element for plants. For this purpose, a factorial experiment was conducted in a complete randomized design with three replications on grapes cv. ‘Fakhri’. The treatments included three levels of potassium silicate (0.0, 1.0 (S.K1), and 2.0 g/L (S.K2)), combined with three levels of humic acid (0.0, 1.0 (H1) and 2.0 (H2) g/L). Morphological, physiological and biochemical characteristics, as well as the microelements of the leaves were measured. The highest yield (10.56 kg/vine) was obtained by simultaneous treatment with S.K2 and H2 solutions. The interactive effects of these two treatments changed the activity of catalase, peroxidase and superoxide dismutase and increased the content of zinc, manganese, iron and copper elements in grape leaves. This result indicates that potassium silicate and humic acid had a synergistic effect and increased all quantitative and qualitative indices of ‘Fakhri’ grapes studied in this experiment.
期刊介绍：
Russian Journal of Plant Physiology is a leading journal in phytophysiology. It embraces the full spectrum of plant physiology and brings together the related aspects of biophysics, biochemistry, cytology, anatomy, genetics, etc. The journal publishes experimental and theoretical articles, reviews, short communications, and descriptions of new methods. Some issues cover special problems of plant physiology, thus presenting collections of articles and providing information in rapidly growing fields. The editorial board is highly interested in publishing research from all countries and accepts manuscripts in English.
