This research was performed to estimate the degree of influence of relative light intensity(RLI) and planting density on the weight growth in the trans-planting bed. The Pinus korgiensis seedling treated for different degrees of shading on seed bed were planted in transplanting bed.
1. The seedling weight growth under 100% relative light intensity and 6x6 plot (36 individuals) density showed the largest growth and the best growth was found during the period from 26th of May to 25th of June. 2. As RLI decreases and with planting density increased, the weight growth decreased. And the weight growth had a tendency to decrease after the period from 26th of May to 25th of June. 3. T/T ratio showed the highest value under 63% RLI and 12x12 plot (224 individuals) of planting density. the highest T?R ratio was found during the period from 26th of July to 25th of August.
Key words: RLI, shading, wight growth, density, seed bed, transplanting bed
