The study was conductedto identify the physiological effect of spraying with Brassinolide and addition methods of active dry yeast
on growth parameters and the chemical content of the grape seedlings (Summer Royal CV).The factor is spraying with Brassinolide with three
levels (0,4,8 gml-1), while the sub factor include four methods of spraying with dry yeast extracts is (spraying with water only, spraying on
leaves, soil, leaves and soil).The spraying with Brassinolide showed a significant influence on all characters studied( seedling length, stem
diameter, leaves number, leaf area, chlorophyll content in leaves, dry weight of shoot and root system and nutrient concentration(NPK) in
leaves. The 8 gm l-1 gave a significant increase in all studied characters as compared to the control. However, the addition of dry yeast extract
showed a significant influence on all characters spraying on leave and soil gave a significant increase. The interaction 8 gm l-1 with leave and
soil spraying was effective combination.
