Abstract:Pongamia (Pongamia pinnata (L.) Pierre) is one of a potential tree species to produce biodiesel. Pongamia-based biodiesel development program is still constrained by the availability of quality and quantity seeds due to the limited of seed sources. The purpose of this research was to identify the morphological diversity of fruits, seeds and seedlings from 5 populations in Java Island. Randomized completely design and randomized block design were used to assess the difference of fruits, seeds and seedlings morphological characteristics among populations. Principal component and hierarchy cluster analysis were used to explain variation pattern among populations. The results showed that the difference of populations was significantly affected by the difference of fruits, seeds, and seedlings morphology of pongamia. Seeds from Carita population showed good quality seed indicators with moisture content of 19.31%, and germination capacity of 74.50%. Sturdiness quotient of the seedling was 10.78. Contribution of genetic factor was higher than environtment factor is relation to the differences of morphological characteristics of fruits, seeds and seedlings of pongamia. Morphological character of the five populations can be divided into 3 groups, i.e. the first group of Batukaras and Kebumen, second group of Alas Purwo and Baluran, and group 3 was Carita.

Abstract:Pericopsis mooniana Thw has a hard seed coat, making it difficult to germinate. This type of seed needs of seed selection and scarification to speed up the germination process, in order to produce a high germination and good seedling. The study aims to increase the value of germination of P. mooniana seed through seed selection based on seed color and scarification techniques. Experimental design used was completely randomized design (CRD) with two factors and three replications. The first factor is seed color (W0 = no selected seeds, W1 = yellowish seeds and W2 = brownish seeds). The second factor is scarification seeds (S0 = without soaked, S1 = soaked in cold water for 24 hours, S2 = soaked in hot water (800C) for 24 hours and S3 = soaked in sulphuric acid/H2SO4 (0.1 M) for 20 minutes. Parameters observed were first time of germination, speed of germination and germination percentage. This study was conducted at the greenhouse, Forestry Research Institute of Makassar in July - August 2015. The result of study showed that yellowish seeds and brownish seed can shortened the time of first germination and increased the germination speed by using scarification technique of seed soaking in hot water to increase germination rate up to 76%.

Abstract:The process of initial handling of seeds is extraction which is using dry or wet methods. The objective of this research was to find out the suitable pod drying period for extracting seeds and decreasing of seed moisture content of sengon laut. The experimental design used was a complete randomized design (CRD). The main factor was drying method under the sun and using seed drier (40C). The results showed that either sun drying for 2 days or use seed drier for 32 hours was the best method for extraction and decreasing of seed moisture content. Drying pods was enable to obtain safe seed moisture content for long-term storage of Falcataria molucana seeds.

Abstract:Standard germination does not always indicate seed lot potential performance, especially if field germination conditions are less than optimal. Seed vigour tests therefore have been proposed to detect more accurate differences in potential seed lot performance. This study is aimed to obtain more precise method to assess Acacia mangium seed vigour correlated to germination success in a greenhouse and normal seedling emergency in a nursery. Tests were conducted on 13 seed lots collected from some certified seed sources. Seed testing and nursery activities were carried out at the Seed Laboratory of Forest Tree Seed Technology Research & Development Centre, Bogor. Experimental designs were arranged in a completely randomized design with four replications for laboratory tests (standard germination, germination index, number of normal seedling in the first count, radicle length, tetrazolium test, controlled deterioration test, accelerated aging, conductivity test), germination in a greenhouse and direct sowing in a nursery. Results showed that all tests were significantly different for ranking seed vigor in the different seed lots. Seed lot from Subanjeriji-2 provided the best germination performance in the greenhouse and direct sowingin the nursery, followed by seed lot from Parungpanjang, while seed lot from Kenangan had the lowest germination performance. The relationship between some laboratory tests, i.e. top paper test, germination index, and electrical conductivity test, and the greenhouse and nursery tests were significant. The electrical conductivity test had the highest accuracy with R2= 0,6278 for greenhouse test and R2= 0,4057 for nursery test. Overall, among all the laboratory tests, electrical conductivity test showed seeds well, so the usage of the electrical conductivity test for predicting normal seedling emergence could be suitable in A. mangium nursery programs.
