Light intensity is considered one of the critical environmental factors affecting seedling development and performance. This study was executed to determine the effects of varying light intensities on the growth of Alangium lamarckii seedlings exposed to three different conditions, namely, 100%, 45%, and 20% light intensity. Data obtained from the study results indicated that the average seedling growth in 45% light intensity condition was greatest, which was closely followed by seedlings in two other light conditions of 100% and 20%. Higher growth of seedlings in 45% light can be attributed to favorable microclimatic conditions observed with the use of moderate intensity light, namely, optimum humidity and moisture which would reduce stress and improve seedling growth. Relatedly, too much exposure to light as well as the considerable decrease in light intensity were noted to be less beneficial for suitable seedling performance. This is evidenced by the fact that A. lamarckii seems to prefer partial shade in the early growing period. The findings of the study indicate that the light intensity of around 45% creates favorable conditions for nursery management as well as early growth of its seedlings.
