Abstract

Forest plantation plays a crucial role in sustainable wood and non-wood productions. Bamboo plantation is a part of forest plantation that have high demand in the global market. Increasing the number of yields with an effective cost management certainly will benefit the plantation owner. However, water stress is the most common event that will be faced by the bamboos, it disturbs the growth and physiological response of the bamboos. Thus, the objective of the study was to determine the growth and physiological response of Dendrocalamus asper under different water treatments. In this experiment, 30 D. asper seedlings were placed in a greenhouse with three treatments of different watering regimes at field capacity: Treatment 1 (50%), Treatment 2 (100%) and Treatment 3 (150%) fo 14 weeks. Six growth and physiological parameters measured were diameter of culm, height of culm, photosynthesis, transpiration, intercellular carbon and stomatal conductance. From the results, Treatment 2 had significantly the highest mean value of diameter while Treatment 3 had the highest mean value of height. There was no significant difference in photosynthesis and intercellular carbon response between the treatments. Meanwhile, Treatment 2 had the highest mean value of transpiration and stomatal conductance. On the average, Treatment 2 had the highest mean value for all parameters thus it is indicate as the best watering regime for D. asper seedlings. Therefore, this study is important for the plantation and nursery managers to determine the best silvicultural practice for D. asper plantation especially on water management.
