The effect of shades on survival and growth seedlings of Persian oak (Quercus macranthera F. et. M.)

In order to have a research on the effect shade on Survival and growth seedling Persian Oak(Quercus macranthera F et. M.), were collected 450 seeds from the forests of the Persian Oak in Western Ardebil. After the cultivation of the seeds in nursury of the natural resources of the region fandoglo, the established plots, in a random complete pattern were exposed by on the complete shades attendance, 50% dark and wanting. The results of this research shows a survival rate of 49% in complete shades attendance,83.9% in 50% shade and 88.4% in the wanting dark attendance. The average of freshness was showed pale or middle freshness in wanting shades attendance, in 50% dark attendance,completely freshness and in the wanting shade attendance, freshness to comparatively freshness.The average of height in complete shade attendance and in 50% shade at 1% statistical probability is significant and in the wanting shades at the probable level from statistical point is insignificant. The average of coller diameter in the complete shades attendance and in 50%shade, was showed significant at 1% statistical probability and in the wanting shade at the statistical probability was insignificant. Consequently, the height average and coller diameter in the shade attendance is 50% more than the complete light attendance and complete shade. Therefore, without any notice to freshness, the shade attendance of 50% has the better situation than the complete light and complete shades for the Persian Oak seedlings.
