Abstract

|
This study was carried out to produce more Parasenecio firmus in forest farming. In order to achieve this purpose, it was surveyed the growth and photosynthetic characteristics of P. firmus. Relatively light intensity was controlled by 100%, 60%, 30% and 5% of full sunlight. Height was the highest under 5% of full sunlight. Shoot diameter was the highest in full sunlight. Fresh weight (leaf, stem, root and total) and dry weight (leaf, root and total) were the highest under 30% of full sunlight. S (leaf + stem)/R (root) ratio was the lowest under 30% of full sunlight and the highest under 5% of full sunlight. In leaf characteristics, leaf area, SLA and LAR were getting higher in the lower light level and the highest under 5% of full sunlight (176.1 ㎠, 420.5 ㎠ ? g?1 and 123.5 ㎠ ? g?1). Especially, leaf area was surveyed higher under 30% of full sunlight in the next. Leaf thickness was getting lower in the lower light level and the lowest under 5% of full sunlight (overall 0.14 ~ 0.24 ㎜). As a result of surveying the whole experiment, P. firmus grows well under 30% and 5% of full sunlight in forest farming.
