ABSTRACTXanthomonas oryzae pv. oryzae (Xoo), is a seedborne pathogen causing bacterial leaf blight (BLB) disease, and reduces the quality of seed and rice production. One of the efforts to control the BLB disease and to improve the quality Xoo infected seeds is the seed coating technique enriched with biological agents. The experiment was aimed to study the effect of coating on seed quality and storage life, as well as the Xoo and biological agents resistence (P. diminuta A6 and B. subtilis 5/B) on the seeds. The experiment was carried out from August 2011 to March 2012, using a split plot design with four replications. The main plot was storage period, i.e. 0, 1, 2, 3, 4, 5, 6, and 7 months. The sub plot was seed coating treatment consisted of negative control (healthy seed); positive control (seeds contaminated with Xoo); seed infested with biological agens; alginate 3% + 1% peat + biological agents; arabic gum 3% + 1% gypsum + biological agents; CMC 1.5% + 1% talc + biological agents; and bactericide streptomycin sulfat 20%. The coated seeds were stored an air-conditioned room (18-20 °C, RH 48-50%). The results showed that the treatments were able to maintain seeds quality during storage, i.e. germination percentage, uniformity percentage, and vigor index, better than those of the positive control. The P. diminuta A6 was still presence (0.08 x 106 cfu mL-1) in seeds coated after 7 month storage, and the B. subtilis 5/B was still presence (0.07 x 106 cfu mL-1) up to 6 month storage with 3% arabic gum + 1% gypsum + biological agents. Keywords: Bacillus subtilis 5/B, Pseudomonas diminuta A6, seed quality, storage space, Xanthomonas oryzae pv. oryzae

ABSTRACTThe use of probiotic bacteria as biocontrol agents is one of the methods of controlling anthracnose disease caused by Colletotrichum acutatum. The objective of this research was to suppress the infection of C. acutatum and increase chilli pepper seedling vigour. The research involved factorial experiments arranged in a completely randomized design with two factors. The first factor was seed coating involving six treatments, i.e., control, seed coating without bacteria, seed coating with Bacillus sp., Pseudomonas sp., Actinomycetes sp, and fungicide. The second factor was the seed storage period where six storage periods were experimented, i.e., 0, 1, 2, 3, 4, 5, and 6 months. The results showed that the coating treatment of Bacillus sp., Pseudomonas sp., and Actinomycetes sp. improved germination, growth rate and number of leaves and reduced the incidence of attacks and infection of hypocotyls at 5 month storage period.Keywords: Actinomycetes sp., Bacillus sp., Pseudomonas sp., seed coating, storage period

ABSTRACTThe use of high quality seed is one of the key factors to improve productivity. Probiotic bacteria has been used to increase plant growth and to control pathogens. The objective of the research was to evaluate methods of chili seed production that yielded high physiological and pathological quality using probiotic fluorescent bacteria Pseudomonas (P24). The bacteria was expected to function as plant growth promoting bacteria as well as capable of controling seedborne pathogen Colletotrichum acutatum causes antrachnose. The experiment was conducted during March until October 2014 in Seed Health Laboratory, Plant Bacteriology Laboratory, and Leuwikopo experimental garden, IPB. The experiment was arranged in a split plot randomized complete block design with three replications. The main plots were untreated and inoculation of C. acutatum. The subplot was six treatments of fluorescent Pseudomonas (P24) application. The results showed that matriconditioning and spraying of fluorescent Pseudomonas (P24) on nursery decreased disease incidence significantly. Matriconditioning and spraying of fluorescent Pseudomonas (P24) on nursery and flowering phase increased number of healthy fruit and total weight of seeds per plant significantly. These applications also increased seed physiological quality indicated by germination percentage (GP) 77.04%, growth rate (GR) 9.72% etmal-1, vigor index (VI) 29.74%, and seed health by suppresed C. acutatum infection up to 12.25%.Keywords: anthracnose, Colletotrichum acutatum, control, matriconditioning, spraying

Nutmeg is an Indonesian native plant, produces essential oill as an export commodity. However, it has low seed uniformity that mengurangi keseragaman tanaman di lapang. The main objective of this research was to obtain morphological characteritics as parameter for nutmeg mother plants selection. This field research was carried out from August-December 2014 at Toisapu, Wakal and Lula nutmeg seed source plantations in Ambon, and Seed Storage and Testing Laboratory, IPB. Characterization was undertaken on ten mother plants from each Wakal and Lula seed source plantations and eight mother plants from Toisapu seed source plantation. Quantitative and qualitative characters of vegetative, fruit, mace and seed from every mother plants were analyzed with Gower’s similarity test. Mother plants that produced high uniformity seed was the 7th (0.80), the 8th (0.93) and the 10th (0.80) mother plants in Wakal; the 2nd (0.80) mother plant in Toisapu; the 2nd (0.82), the 5th (0.80), the 6th (0.82), the 8th (0.84), the 9th (0.80) and the 10th (0.93) mother plants in Lula. Those selected mother plants produced morphological uniform seed morphologically. Lula seed plantation had the highest uniformity level among mother plants (0.77-0.87) compared to Toisapu (0.70-0.87) and Wakal (0.69-0.84) mother plants. The morphological characteristic can be use to select the source seed mother plants which able to produce high morphological uniformity seeds.Keywords: Gower’s similarity, seed production, uniformity

Experiment 2 used Split Plot Design with four replications. The main plot was storage periods i.e. 0, 1 and 2 months. The seeds were stored in two storage conditions: ambient and air conditioned room. The subplot was coating formula (same as in Experiment 1). The results of Experiment 1 showed that the most compatible coating material for rice seeds were 1.5% CMC + 1% talc, and 1.5% CMC + 1% gypsum, these formula were able to maintain vigor of the coated seeds. In Experiment 2, coating formula of 1.5% CMC + 1% peat generated higher seed vigor than uncoated seeds after two months storage, 3% gum arabic + 1% gypsum was able to keep vigor for one month storage in ambient condition. The coating formula of 3% alginate + 1% peat was able to keep viability and vigor of the coated seeds for two months in air conditioned room.

True shallot seeds are preferable to tubers as planting materials because of their advantages in storage longevity, lower management cost, and lower seed-borne disease risk. However, environmentally limited production and seed deterioration in uncontrolled storage have limited its application. Pre-sowing hydration invigoration accelerates and synchronizes the germination of deteriorated seeds. Ultra-fine bubble water (UFBW) contains reactive oxygen species, which can advance the pre-germinative metabolism of the seed. This study examined true shallot seed invigoration using UFBW. The experiment was conducted in a two-factor of randomized complete block design. The first factor was initial seed vigor based on the vigor index with six levels, i.e., 24, 15, 13, 12, 10, and 9%. The second factor was the invigoration treatment of UFBW (8 and 23 ppm dissolved oxygen concentrations) with two durations (24 and 48 h), 50 ppm GA3, and 3% KNO3 (24 h). UFBW with 23 ppm invigoration for 48 h improved seed vigor based on all vigor parameters. The GA3 50 ppm treatment is the most effective in increasing seed vigor.

Pengujian viabilitas benih menggunakan uji tetrazolium merupakan salah satu metode penentuan viabilitas benih dengan mengevaluasi tingkat warna merah yang terbentuk pada benih. Warna merah terbentuk dari aktivitas enzim dehidrogenase pada siklus trichloroacetic acid. Penentuan tingkat warna merah pada benih ini dapat menggunakan alat sensor infra red. Penelitian ini bertujuan menguji alat sensor infra red untuk menentukan intensitas warna secara kuantitatif dalam uji tetrazolium serta menentukan korelasi alat sensor infra red dengan pengujian benih secara fisiologis. Percobaan disusun menggunakan rancangan kelompok lengkap teracak dengan faktor tunggal yaitu tingkat viabilitas benih berdasarkan daya berkecambah masing-masing adalah 78.9%, 70.7% dan 40.0 %. Hasil penelitian menunjukkan bahwa aplikasi sensor intensitas infra red untuk uji tetrazolium pada benih kacang tanah menghasilkan nilai koefisien korelasi (r) sebesar 0.62 antara nilai RGB merah bagian dalam kotiledon (Rd) dengan kecambah normal. Kata kunci: daya berkecambah, enzim dehydrogenase, kotiledon, mutu fisiologis benih, RGB
