Abstract

Acacia crassicarpa improved seed has a higher quality than unimproved seed. To maintain the viability, improved seeds are required as appropriate handling techniques. One of the important steps in seed handling is seed germination test. A. crassicarpa seed have dormancy and to break it needs specific pretreatment. Germination test can be worked in the laboratory and greenhouse. The purpose of this research was to obtain pretreatment and germination method better to maintain the viability of A. crassicarpa improved seed. Pretreatment in resources were without treatment, soaking in hot water (100oC ) and followed by soaking for 24 hours in cold water, soaking for 1 minute in hot water (100oC) followed by soaking for 24 hours in cold water, soaking for 6 minutes in hot water (100oC) followed by soaking for 24 hours in cold water, soaking for 30 minutes in H2SO4 , torn of seedcoat, and torn of seedcoat and then soaking for 24 hours in cold water. Laboratory Germination method were top of paper (TP), between paper (BP), and pleated paper (PP) test. Whereas growing media used in greenhouse were top soil, sand, a mixture of top soil and sand (1:1/v:v), and cocopeat. The results showed that to maintain the viability of A. crassicarpa improved seed required the best pretreatment technique and germination methods were (1) in laboratory used combine between torn of seedcoat and top of paper. In this method, the percent of seed germination reached 96 %, and (2) in greenhouse used combine between torn of seedcoat and cocopeat. In this method, the percent of seed germination reached 88 %.

Abstract

Seeds with high vigour are seeds that can germinate normally in sub-optimum conditions and above normal in optimum condition. To predict the performance of seedlings after planting and the storability of seeds, it is necessary to test the seed vigour. This study aims to investigate the growth and storage vigour of Acacia mangium breeding and unbreeding seeds. The experiment design was arranged in completely randomized design with each treatment being replicated four times with 100 seeds. Results obtained showed that breeding seeds had better growth and storage vigour.

Abstract

Benih Eucalyptus pellita mempunyai ukuran yang sangat kecil, sehingga diperlukan teknik sortasi benih dengan menggunakan ayakan untuk meningkatkan mutu fisiknya. Penelitian ini bertujuan untuk menentukan ukuran ayakan yang sesuai untuk sortasi benih E. pellita sehingga dapat meningkatkan viabilitasnya. Benih E. pellita yang digunakan dalam penelitian ini berasal dari kebun benih semai (KBS) yang terdapat di Sumatera Selatan, Kalimantan Selatan, dan Riau. Sortasi benih dilakukan dengan menggunakan beberapa ukuran ayakan, yaitu ukuran 200 μm, 400 μm, dan 600 μm. Parameter yang diamati adalah kemurnian, berat 1000 butir benih dan daya berkecambah. Hasil penelitian menunjukkan bahwa ukuran ayakan 600 μm merupakan ukuran ayakan yang sesuai untuk sortasi benih E. pellita, karena dapat menghasilkan berat 1000 butir (0,0362 gram), kemurnian (60,54%) dan daya berkecambah (184 kecambah/0,1 gr) benih E. pellita yang paling tinggi.

Abstract

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).
