Abstract
Nowadays burcucumber(Sicyos angulatus L.) has been widely used as a rootstock of Cucurbitaceae. The study was done to examine the effects of shading with different colored fabrics(white, red and aluminum-coated) on growth and cotyledon chlorophyll content of its seedling. Shading with the white colored fabric lengthened seedling height and hypocotyl length, but shading with the red colored fabric enlarged true leaf area. Total dry weight of each seedling was decreased in the order of no shading, white, red and aluminum, in which resulted from reductions of cotyledon dry weight in white colored fabric, cotyledon and true leaf dry weight in red colored fabric, and dry weight of cotyledon, true leaf and root in aluminum colored fabric. Cotyledon chlorophyll content was reduced by shading treatments although the 3 shading treatments showed nearly same content.
