Abstract

This research was aimed to find out information on the growth and physical quality of Shorea leprosula Miq. seedlings propagated from shoot cutting at three different levels of age. The research was carried out through growth observation and physical quality assessment at 11-, 12-, and 14- month- old after acclimatization (MAA). The observation and assessment were done to ten seedling samples of each age level which were selected through a simple randomized sampling method. The results showed that height of 14 MAA Shorea leprosula Miq. seedlings was significantly different from other age levels (p < 0.05). On the other hand, the physical quality of seedlings was not different between age levels of seedlings. At seedling age of 11 MAA (S1), the seedling was ready for planting with height of 32.6 cm, sturdiness value of 10.79, shoot/root ratio of 2.58, and seedling quality index of 0.28.
