บทคัดย่อ (EN): The influence of normal (571 trees/ha) and high (1,111 trees/ha) planting densities on some important tree attributes of nine studied cloned was discussed in the present study. The absence of significant interactions between clones and planting density in girth growth, latex yield, tapping panel dryness and bark thickness was recorded in immature stage and the first tapping panel (BO-1). Meanwhile, there were the significant interactions between clones and planting density on girth growth, girth increment and latex yield in the second tapping panel (BO-2) and the following tapping years. Statistical comparison of mean diameters at breast height and bole volume per tree of the same clones at two different planting densities showed that most of the studied clones gave significant difference. However, there was no significant differences resulted comparison of mean BH of the same clones at two different planting densities. The total bole volume per hectare of all studied clones was larger at high planting density than at normal planting density, but the bole volume per tree at high planting density was smaller than that at normal planting density. Clone RRIC 121 could be considered as a suitable clone for both latex and timber productions, followed by RRIV 2 and PB 235. The favorable planting density for commercial timber production is higher planting
