摘要：The reduced area of mangrove forests due to various pressures required rehabilitation activities throughout the damaged area of mangrove forests. Rhizophora mucronata is one of the plants in the mangrove ecosystem that has stilted roots to stand the ocean waves. It is necessary to provide R. mucronata seedlings in mangrove rehabilitation. This study aims to determine the best shade intensity for root growth of R. mucronata seedlings. This research was conducted in the nursery of Jaring Halus Village, Langkat, North Sumatra, during three months cultivation. This research used the utterly random design with five treatments, namely 0%, 25%, 50%, 75% and 100% of shading, for ten replications. The results showed that 0% shade intensity had a better growing number of primary and secondary roots and root length than the others of shade intensity. In this study, it is also estimated that the spacing planting of R. mucronata seedlings was better at 3 x 2 meters for rehabilitation activity.
