Effect of varied salt concentration and freshwater adaptation to the growth of Bruguiera cylindrica seedlings

Abstract

Mangroves are recognized as plants growing in the intertidal zone. The early of mangroves growth was affected by environment salinity. This study was purposed to determine the effect of salinity and subsequent freshwater on the growth of Bruguiera cylindrica. The study was conducted in a greenhouse for three months using a salinity of 0%, 0.5%. 1.5%, 2%, 3% as many as 10 repetitions. After three months, the seedlings were divided into two treatment groups another three months. Five repetitions were continued with various salt concentration, and five replications underwent freshwater re-adaptation. Parameter measurement used was height seedling, stem diameter, leaf number, leaf area, and wet weight and dry weight (leaf, root, and stem) B. cylindrica seedlings. According to the growth parameter of seedlings, B. cylindrica showed the best growth at 0.5% and 0.5% to 0%. The higher salinity could inhibit B. cylindrica seedlings.
