Anchor for Mangrove Rhizophora sp Propagules

“…Anchors for tubular propagules with a length of 20 cm with diameters of 0.5, 1, 2, and 4 inch were tested, the analysis using one way ANOVA showed the difference was p<0.001, followed by the Tukey post hoc test which showed that the anchor with a length of 20 cm with a diameter of 4 inches had the ability to withstand high the highest with a weight of breaking load 9,618.33+96 g. The survilan rate using Anchor model D diameter 4 inch height 20 cm is 100%, the protectors, such as PVC pipes, may increase survival rates [6][7]. In the natural the propagule need 5,4 day to be able sink to reach the sediment [2], the result shows higher percentage than the natural propagules dropped into the vegetated area were retained and survived to the seedling stage over 50% [8], many of the propagules which do not succeed in establishing themselves are carried away by the tide [9]. The survival of the propagule having protection is higher that non protection [10], the direct propagule planting give higher growth compare to that grow in the polybag [5].…”
