The attack Ganoderma boninense can caused stem rot of oil palms that occur at all stage of plant growth. Trichoderma asperellum endophytic can suppressed the attack of Ganoderma in a nursery by utilizing seed coating technology. The aim of this study was to determine the best formula of seed coating materials which is compatible with T. asperellum (T13). The first experiment consisted of two phases, namely, the first phase was testing the effectiveness and compatibility of T. asperellum through a mixing technique of T. asperellum suspension with coating material. The best three result on the first phase (25 percent arabic gum, 1 percent CMC, and 3percent arabic gum + 1 percent gypsum) were used in the second phase of the experiment, which was testing the effectiveness and compatibility of T. asperellum through soaking technique in T. asperellum suspension that continued by coating. The three best result types of formulas from the second phase (1 percent CMC, 1.5 percent CMC, and 4,5 percent arabic gum + 1,5 percent gypsum) were used for the second experiment, namely testing the resistance of oil palm seed on Ganoderma. The results show that 25 percent arabic gum, 1 percent carboxy methyl cellulose (CMC), 1 percent arabic gum + 1 percent gypsum have a potency as coating of materials. The best formula for seed coating is soaking with T. asperellum + coating 1 percent CMC, 1.5 percent CMC and arabic gum 4.5 percent + gypsum 1.5 percent. In addition, soaking seeds with T. asperellum + coating 1.5 percent CMC can enhance the ability of seed to grow up to 16.67 percent compared to the control, but did not effective in suppressing G. boninense infection during pre-nursery stage.

Quantity and Quality of Sengon Sprouts at Some Levels of Seed Viability and Rhizoctonia sp. InoculationThe purpose of this research was to evaluate the quantity and quality of sengon sprouts with several levels of seed viability and inoculation of Rhizoctonia sp. Materials used was three lots of sengon seed with different levels of viability obtained from Forest Management Unit Pare - Kediri and Rhizoctonia sp. isolate cultured on PDA media. The treatments tested were 3 levels of seed viability and 4 levels of Rhizoctonia sp. inoculum. The results showed that seeds with higher viability levels (seed germination = SG 87 and 83 %) produce more sprouts, indicated by the germination percentage which was significantly higher than that of seeds with lower viability. Rhizoctonia sp. inoculation decreased the number of sprouts, indicated by the germination percentage which was significantly lower. The attacked of Rhizoctonia sp. on sengon sprouts was not associated with the level of seed viability, the lowest inoculum levels (3 corkborer 10-1 ml media) caused high percentage of seedlings death (57%) even at the seed with high level of viability (SG 87%). The quality of the sprouts were not influenced by the level of seed viability, indicated by the length of roots and hyphocotil of normal sprouts which was not significantly different of sprouts from the seed with higher viability level (SG 87%, root length 2,71 cm, hypocotile length 3,00 cm) than that of the seed with lower viability level (SG 56%, root length 2,38 cm, hypocotile length 2,66 cm).

Peanut seed tetrazolium test evaluation is usually by eye and a microscope. This method has a weaknesses in the accuracy of reading the color intensity, and is more subjective. The seeds was observed one by one so that the observation is not effective. To make observations more accurate, efficient, and effective, digital image processing can be applied to the seed viability evaluation. The method can be used was the detection of the Hue, Saturation, and Value color area in reading the red color pattern resulting from tetrazolium test.The result is the system can detect a maximum of 25 seeds with an operational time of 22-25 seconds in one detection. Seed classification is the seeds are predicted to normal, abnormal, and dead. The process of classifying seeds is identified based on the red color pattern resulting from the detection of the area of 4 HSV color ranges, namely red (175,100,20:180,255,255), pink (160, 100,20 : 174,150,255), white 1 (175,0,0 : 180,100,255), and white 2 (0,0,0 : 100,255,255). The results show that the accuracy of the system in reading the total number of seeds is 100% with the detection error of HSV color area is 1.54%.

Permasalahan utama dalam pengembangan tanaman jahe putih besar (JPB) adalah terbatasnya ketersediaan rimpang benih bermutu dalam jumlah yang mencukupi, pada waktu diperlukan oleh pengguna. Permasalahan tersebut antara lain disebabkan oleh produksi dan mutu rimpang benih yang masih rendah, serta bobot rimpang benih yang cepat menyusut dan mudah bertunassaat di penyimpanan. Penulisan ini bertujuan untuk menginformasikan kepada pengguna tentang karakter pola pertumbuhan, keseimbangan hormonal dan perubahan fisiologis yang menjadi faktor perhatian utama dalam peningkatan produksi dan mutu JPB melalui aplikasi zat pengatur tumbuh (ZPT).Peningkatan produksi dan mutu dapat dicapai dengan penggunaan rimpang benih bermutu yang diperoleh melalui: penentuan pola pertumbuhan, pengaturan keseimbangan hormon, baik secara alami (pengaturan iklim mikro), maupun dengan pemberianZPT selama proses produksi di lapangan dan di penyimpanan. Beberapa hasil penelitian membuktikan bahwa: (1) Pola pertumbuhan tajuk dan rimpang JPB selama pembentukan dan perkembangannya secara umum diklasifikasikan atas tiga fase yaitu: fase lambat 1–4 bulan setelah tanam (BST), cepat (> 4–6 BST), dan pemasakan (> 6 BST).Rimpang benih JPB umur 7 BST sudah dapat digunakan sebagai bahan tanaman.

ABSTRACT The main problems in the development of big white ginger plant (BWG) is the limited availability of quality seed rhizomes in sufficient quantities, at the time required by the user. Its caused by the production and quality of seed rhizomes are still low, and the seed rhizomes weight are rapidly shrinking and sprouting when in the storage. This Overview aims to inform users about the character of the pattern of growth, the balance of hormonal and physiological changes that are primarily focused on the production and seed quality improvement BWG through the application of plant growth regulator (PGR). Increased production and quality can be achieved by the use of quality seed rhizomes obtained through: determination of growth patterns, hormonal balance regulation, both naturally (microclimate regulation), as well as by application of growth regulators (ZPT) during the production process in the field and in storage. Some research results showed that: (1) The growth pattern of the canopy and GWB seed rhizomes during its formation and development is generally classified into three phases: slow phase 1-4 months after planting (MAP), fast (> 4-6 MAP), and maturty (> 6 BST). (2) Differences in planting location and harvest age affect the balance pattern of plant endogenous hormones (ABA / GA and ABA / cytokinin (zeatin) hormone ratios) and the BWG seed rhizomes quality. ABA / cytokinin ratios are higher in BWG seedlings aged 7 MAP (5.0) and 8 MAP (4.7) compared to 9 MAP (4.2) for seed rhizomes from Nagrak, so they are able to trigger and maintain dormancy so Its are more resistant to storage. (3) The dormancy period of BWG seed rhizomes break after stored for 2 months and this is a critical period or an appropriate period for sprouting inhibition treatment. (4) Application of PBZ 400 ppm increased production and quality of BWG seed rhizomes, namely: wet weight (22%) and number of branch rhizomes (68%) with rhizome characteristics: small, short and filled out internodes compared without PBZ. (5) Application of PBZ 1000 ppm, at a storage temperature of 20-22 ºC, can reduce weight loss by 15% compared to control, after stored for 4 months and also can reduce the sprouting percentage of rhizomes by 26% after stored for 3 months.

The seed viability test is one of the routine tests carried out in the seed certification process. Decreasing the viability of seeds can be done biochemically and physiologically. This research aimed to study of seeds deterioration through physiological and biochemical tests. This study used two lots of long bean seeds (high and low lot). Physiologically, the seed viability test was carried out by means of germination test and biochemical by means of respiration test using tetrazolium (TTZ) staining technique and titration method. The experiment designed by completely randomized design one factor. Data were analyzed by anova test and Pearson correlation. The results of research showed that the seed lot treatment was significantly on the tetrazolium test and the total dry weight of sprouts, while the vigor index, seed germination, and respiration index measurements did not show significant. There was a high positive correlation in the high respiration rate of high seed lots and low seed lot seeds on total dry weight of germination, germination, vigor index, and tetrazolium test. Therefore, biochemical tests with TTZ and respiration with titration methods can be used as alternatives to predict rapid deterioration of seeds.
