Effect of Shading on Organic Pepper Seedling Cultivation

Abstract

The experiment was carried out in the temperature-controlled glass sera during July and August 2010. In order to create different light intensities for each period after seeding, material with 50 % shading property was used as 1, 2 and 3 layers also created an unshadow area for control purposes. Yalova Carliston pepper cultivar was used in the research. In the experiment, root dry weight, stem dry weight, leaf dry weight, leaf thickness and net assimilation rate were determined from seedling quality parameters. A statistically significant difference was found between all parameters in terms of the characteristics examined (p<0.01). Leaf thickness values decreased with shading. The highest net assimilation rate was determined in the control application in which the highest temperature values were determined.
