Effect of Colored Polyethlene Film over the Rooted Cutting of Landscape Trees

Abstract

This report was made to inform the effect of colored polyethylene films.
We planted rooted cuttings of Kin-mokusei in a propagation bed and covered them with polyethylene films, using both ways of tunnel and mulch. The colored films used for the test were transparent, gray, red, orange, green, blue, and purple. As the test was given in the summer, we shaded all parts of the propagation bed from the sun with cheesecloth and marsh reed screens. The shade effect was 90%.
The taking root percentage of all the rooted cuttings which we planted was 100. The rooting percentage was 97 in the section shaded in green polyethylene films, which turned out to be superior to other section. But the growth and development of the roots were inferior to other section and we finaly found that transparent films were the best.
We concluded from this report with the results that if the shade effect was 90 %, and the nonirrigation cuttings of Kin-mokusei obtained better result than those other conditions in the summer season.
