摘要

This study was conducted to determine the effects of two different biostimulants (Agrozym and Almina) with their four different concentrations (0, 5,10, 20 g per pot), for plant characteristics of 'Syrah' vine saplings and soil structure in 2006. The experiment was done with 5 repetitions and each replica consisted of 3 plants. Plant and soil samples were collected and analyzed two months after budding. According to results obtained, while macro plant nutrient of levels (N, P, K, Ca, Mg, S) did not change, the micro nutrients (Mn, Fe, Zn, Mo, B) increased greatly. Increased application doses led to decrease in micronutrient uptake. With the increase in biostimulant doses, the micronutrient levels increased with decreasing velocity compared to control. Highest level of Fe and Mn in leaves was obtained for both biostimulants with 10 g per pot dose; however, Zn and B levels tended to be decreased by increasing biostimulant dose comparing to control group. Both Agrozym and Almina had no effect on N, P, K, Ca, and Mg in roots. On the contrary, Mn, Fe, Cu, and Zn uptake increased. In soil analyses, it was found that Agrozym and Almina had little, if any, effect of soil pH and EC, on clay and organic matter level of soil. When the soil nutrients were examined K, Mn, Fe, Cu, and Zn did not show any significant change while N, P, Ca, Mg increased dramatically.
