Abstract

Sea grass is one component of biodiversity in marine waters composed of many species with various morphological characters. The aim of this study was to obtain the morphological data of seagrass species on the East and West Coasts in Nature Reserve of Pangandaran. The method used was survey method and line transect as far as 200 meters with random sampling technique. Measurements were made for each species of seagrass in the leaf length, leaf width, leaf thickness, stem length and rhizomes length and root length. The results showed that on the East Coast founded three species of seagrass were Cymodocea rotundata, Thalassia hemprichii and Halodule pinifolia, while on the West Coast founded one species of seagrass was Thalassia hemprichii. Cymodocea rotundata has characteristic rounded edges with slight curvature in the middle, Thalassia hemprichii has rounded, brown tip and a brown patterned rhizome, and Halodule pinifolia has side toothed leaf tip with part of the middle there are brown leaf veinsKey words: sea grass, morphology, Pangandaran Nature Reserve

Abstract

Yellow ampel bamboo is one type of bamboo that has economic value. One effort that can be done for maintaining the existence of bamboo population so that its can be sustainably used through the cultivation of branch cuttings. The success growth of branch cutting can improve with using plant growth regulator (PGR), such as NAA and Rootone F. The aim of this study was to get the best kind and concentration of PGR that can promote the growth of ampel yellow bamboobranch cutting. This study used experimental methods with a completely randomized design (CRD) two factors. The first factor wasthe kind of PGR which consists of two levels: z1 = NAA and z2 = Rootone F. The second factor was the concentration of PGR which consists of six levels: k1 = 0 ppm, k2 = 100 ppm, 200 ppm = k3, k4 = 300 ppm, 400 ppm = k5, and k6 = 500 ppm. Data were analyzed using ANOVA (α = 5%) and to know the difference between treatments used Tukey test (α= 5%). The results showed that the Rootone F had a better effect than NAA on the growth of yellow bamboo branch cutting. Concentration of 200 ppm was the best concentration to the growth for branch cuttings of yellow ampel bamboo. Interaction Rootone F and concentration 200 ppm showed the best result to the growth for branch cuttings ampel bamboo.Keywords :branch cutting, ampel yellow bamboo, NAA, Rootone F
