The Seedling Growth, Chlorophyll Contents and Photosynthesis in Different Sites in La Mesa Watershed, Philippines

摘要

This study intends to 1) identify the best species for afbrestation in the grass land in La Mesa watershed and 2) compare the growth between flat land and mountain area in the same region. The research activity was divided into three different experiments; Treatment I- effects of different planting density on the two areas, Treatment II- growth comparison between nitrogen fixing species and non nitrogen fixing species, and Treatment Ill-effects of grass treatments After we established the experimentplantation, height growth, total chlorophyll contents and photosynthesis were monitored. Generally, the height growth and total chlorophyll contents of four species grown in the mountain area were higher than those of seedling grown in flat land. In addition, photosynthetic rates of four species grown in the mountain area were higher than those in flat land.
