The Effect of Method and Germination Paper Substrate on Viability of Eucalyptus Pellita F. Mull Seed

Improper seed handling of Eucalyptus pellita will reduce seed quality, so as to improve the viability of the seed proper handling techniques are needed. To investigate the seed germination potency as a result of seed handling germination seed tests are needed. The purpose of this study was to examine the effect of germination method and paper substrate on the viability of E. pellita seeds. Seeds used in this study were from seedling seed orchard in South Sumatra, South Kalimantan, and Riau. Seed germination methods used in the laboratory tests were method of top paper and between paper tests, besides that, different papers were used such as: paper substrate namely straw paper, towel paper, filter paper, and newspaper. Factorial experimental design completely randomized was used. The results showed that: (1) the method of germination and paper substrate was significant (2) the best paper substrate and germination method was the method of top paper test with used media of newspaper (germination percentage 204 seedling /0.01 grams).

Growth of Nyamplung (Calophyllum Inophyllum L.) on Three Planting Patterns and Dose of Fertilizer on Sandy Beach Pangandaran, West Java

Nyamplung (Calophyllum inophyllum L.) is one of the new alternatives of biofuels materials in the world. Hitherto, the information on the cultivation and processing techniques is very limited. This study aims to find out the growth of nyamplung on some cropping patterns on sandy beach Pangandaran in 4 (four) years. The experimental design used in this study was split plot design. The main plots were cropping pattern: agroforestry nyamplung, nyamplung monoculture and nyamplung + pandanus, and the subplot were fertilizer doses: (1) no fertilizer (control), (2) 5 kg of organic fertilizer + 100 gr/plant NPK and (3) 10 kg of organic fertilizer + 200 gr/plant of NPK fertilizer. Each combination treatment consists of 25 plants that were repeated 3 times , so that the total number of plants observed were 675 plants. The growth parameters observed: survival rate, height, diameters and number of branches of plant until 4 years. The results of this study showed that the interaction of treatments were statistically not significant. The growth of the plants was significantly affected by cropping pattern and fertilization. The Agroforestry pattern produces the highest survival rate and growth that is 97.33% with an average height of 220 cm and an average diameter of 5.08 cm. Recommended fertilizer doses are 5 kg of organic fertilizer for base and 100 grams of advanced fertilizer NPK twice a year.

Pendugaan Parameter Genetik Semai Nyawai (Ficus Variegata Blume) Asal Pulau Lombok

Genetic parameters were estimated for height and diameter characteristic of Ficus variegata Blume seedlings planted in the nursery of The Centre for Forest Biotechnology and Tree Improvement, Yogyakarta at 8 months of age. The trial involved seedlings from several mother trees (family) originated from Lombok Island. The trial was arranged in a Randomized Complete Block Design (RCBD) which comprised of 17 families as treatment, 3 replications and each replication comprised 10 seedlings. Analysis of varians showed that height and diameter were significantly different between families. Family heritabilities for height and diameter characteristic were 0.98 and 0.91 respectively, while genetic correlation between the two characteristics were 0.7. This information is very important for future genetic improvement of the species.
