Abstract

Bambara groundnut (Vigna subterranea (L.) Verdc) is a potential commodity to be developed in Indonesia, however, the production is done only once a year, therefore, it needs proper seed storage. The aim of this research was to study seed deterioration patterns of four bambara groundnut landraces stored in packages with different permeability in an open storage system for up to 6 months. This experiment was conducted from November 2015 to July 2016 at Seed Technology Laboratory, Department of Agronomy and Horticulture, IPB. Stages of experiment as follow: calculation of packaging permeability, seed storage, preparation and fitting data to regression equation.The packaging used in the study is aluminum foil, pp plastic and plastic sacks which have measured its permeability. The result showed that the seed deterioration of four bambara groundnut landraces in three packaging permeability has common sigmoidpattern with equation model: y = a / {1 + exp ((x + b) / c)}. The seed deterioration pattern based on SG and EC variables with the faster rate of decline occurred in Sumedang landrace packed in plastic sack (permeability = 1.4681 g/day m2 mm/Hg), thus having a shorter storability. The slower rate of decline occurred in Gresik landrace packed in aluminum foil (permeability = 0.098 g/day m2 mm/Hg), this means that it has a longer storability.

Abstract

Bambara groundnut seeds often show unsynchronized and slow germination even though on newly harvested seeds. This might be due to the presence of seed dormancy. Therefore, the objective of this research was to obtain the information on seed dormancy and germination behaviour of bambara groundnut seeds during desiccation. The experiment was arranged in a nested design. Dormancy breaking treatments (untreated, mechanical scarification, soaking in 1% KNO3 for 2 hours, mechanical scarification followed by KNO3 soaking) were nested in each of the desiccation levels (fresh seeds with 54.7% moisture content (mc), desiccated seeds with 44.4%, 18.0%, 15.4%, and 12.1% mc). The results showed that newly harvested seeds were in dormant state. Seed desiccation did not increase the intensity of seed dormancy, even resulted in an increase in field emergence (at 30 days after planting) from 43.9% in fresh seeds to around 70% in dry seed (12-15% mc). Seed desiccation (from 44.4% mc to 12.1% mc) increased the field emergence, although it was inadequate to break the dormancy completely. Meanwhile, seed desiccation tended to increase the GA/ABA ratio, but the seed permeability was decreased. The fact showed that seed desiccation reduced the intensity of dormancy of bambara groundnut seed, therefore, it is suggested to modify the drying method in order to accelerate the increasing of GA/ABA ratio while keeping the testa permeable.

Abstract

Soybean seed viability declines during seed storage. Soybean seed deteriorates rapidly, affected by its high protein content and often high humidity in the tropical environment. This research was aimed to develop dynamic model of soybean seed viability in an open storage. The study was conducted in three stages, namely: 1) desk study, 2) seed storage experiment, 3) development of seed storage model, simulation and verification of the model. The second stage of the experiment consisted of soybean seed storing and germination testing using completely randomized design. Treatments were three initial moisture content (7-8%, 9-10% and 11-12%) and four varieties of soybean (Anjasmoro, Wilis, Detam-1 and Detam-2). The results showed that the seed behaviour during storage period were affected by initial seed moisture content, initial viability, varieties and environmental condition. Therefore, seed moisture content, initial viability and varieties may be used as input model. Moisture content, integreting seed respiration, electric conductivity and seed storability vigor (VDSDB) were as model output. Simulation of Seed Storability Vigor Prediction Model with Model Construction Layer-Stella (MCLS) using relative humidity (RH), temperature, seed permeability, initial moisture content and initial viability as input model could logically predict the seed moisture content and seed storability vigor (VDSDB).

Abstract

Accelerated Aging Machine “IPB 77-1 MM” could be used for soybean seed screening based on the seed storability vigor. The aim of the research was to identify simple, fast and accurate accelerated aging method using accelerated aging machine IPB 77-1 MM. Two methods of accelerated aging test (physical and chemical treatment) were applied to seeds of Anjasmoro soybean variety. The best accelerated aging method was then used to screen seed storability vigor of 23 soybean varieties. Seed storability vigor of 23 soybean varieties were detected using accelerated aging machine IPB 77-1 MM and each was compared with the seed storability vigor of those stored 10 weeks in controlled storage. Results of the experiment showed that using chemical or physical treatment on accelerated aging process were able to decrease seed vigor, but chemical treatment decreased seed vigor faster, more simple and more practical. Accelerated aging machine IPB 77-1 MM could also be used for screening varietal seed storability vigor of soybean using electrical conductivity test.

Abstract

Swamp land ecology is a potential land to increase the crop production, especially rice. The research was aimed to increase the production and seed quality of IPB 3S rice variety in swamp land ecology. The research was arranged in Factorial Randomized Complete Block Design with three replications. The first factor was dose of Zinc, consist of 0 kg ha-1, 15 kg ha-1, 30 kg ha-1, and 45 kg ha-1. The second factor was seed treatment by probiotic microbial, consist of control, Bacillus sp, Bacillus sp (+), Chromobacterium sp, Chromobacterium sp (+). Zinc fertilization couldn’t increase the yield characters and seed quality of IPB 3S rice variety. Microbia fertilization could increase the highest yield characters (plant height, tillers, productive tillers, panicle length, weiht per plant, and seed weight per grove), and Bacillus microbial increased the seed quality (Vigor index). Interaction of zinc fertilization (15 kg ha-1) and Chromobacterium increased the yield characters (flag leaf length, panicle length, and seed weight per grove), and the interaction of zink fertilization (30 kg ha-1) and Bacillus increased seed quality (vigour index).

Abstract

The low production of hybrid rice seed is influenced by the syncronized of flowering time between CMS and restorer. One of several ways to syncronize both two CMS and restorer was use gibberellins. Gibberellins as growth regulator worked by triggered plant growth and flowering. The objective of this research was to obtain the optimal concentration of GA3 to support the  increase hibryd rice seed production. The experiment was arranged in a split plot design based on randomized complete block design. The first factor was three hybrid rice varieties (V) i.e. V1 Hipa-8 (A1 and PK91), V2 Hipa-14 (A7 and PK92) and V3 Jatim-3 (A6 and PK88) belong to the Center for Rice Research (BB Padi) as the main plot and the second factor was four level concentrations of gibberellins (GA3) i.e. G0 (without GA3), G1 (GA3 150 ppm) G2 (GA3 200 ppm) and G3 (GA3 250 ppm) as a subplot. The treatment was  performed by spraying GA3 with spray volume of one liter per a plot on the female and male parent. The results of experiment showed that concentrations of GA3 treatment significantly increased plant height, angle of floret opening and decreased number of empty spikelets. The treatment interaction of GA3 concentration and variety significantly effected on percentage of increasing plant height and productivity. The highest productivity was rice hibryd of  A7 (Hipa-14) of 1 000 kg/ha with application of 200 ppm GA3.

Abstract

ABSTRACTPhysiological quality of soybean seeds was easily deteriorated during storage. The objectives of the research were to determine controlled deterioration test which could be used to evaluate soybean seed viability and to find the appropriate controlled deterioration test for estimating storability of soybean seed. The research was conducted at the quality control laboratory PT. BISI International, Tbk., Kediri since October 2012 until February 2013. The completely randomized design with four replications was used in the experiment by moisture content and deterioration periods as treatment. The results showed that the controlled deterioration periods to evaluate two varieties of soybean seed were same for 16 hours at 17.5% moisture content for Wilis and 15% moisture content for Detam-1. The result also showed that there were significant correlations between controlled deterioration values with actual values from 16 weeks storage periods, indicating controlled deterioration test periods could estimate storage periods. Verification of seed vigor relation to storability model showed there were no significant differences between germination and speed of germination between controlled deterioration and actual values. Simulation of soybean seed storability model with germination percentage after controlled deterioration as input variables could predict the storage periods.Keywords: Glycine max, rapid ageing, seed modelling, seed vigour, vigour index

Abstract

ABSTRACTCharacterization and evaluation of genetic potential of bambara groundnut accessions is very important in order to obtain accessions with high yield potential and early maturity. The objective of this research was to study the phenology, morphology, and yield of four bambara groundnut accessions. This experiment was conducted using a randomized completely block design with one factor i.e. origin of accessions (Bogor and Sukabumi black testa, Sumedang black and brown testa). The results showed that days to seedling emergence of Sumedang brown testa were 9.7 days after sowing (DAS), three other accessions ranged from 8.0 to 8.3 DAS. Days to 75% flowering of Sumedang brown testa was 45.3 days, the other three accessions ranged from 46.0 to 46.7 DAS. Days to pod formation of Bogor and Sumedang accessions with black testa were 49 DAS, Sumedang brown testa at 50 DAS, and Sukabumi accession at 54 DAS. Physiological seed maturity of Bogor and Sukabumi accessions at 112 DAS, Sumedang brown testa at 116 DAS and black testa at 128 DAS. Morphological variation of four bambara groundnut accessions included color of plumule, petiole, seed coat (testa), and leaf shape. Accessions of Sukabumi and Bogor black testa were potential to be developed further because of its showing higher number and weight of pods, and earlier maturity compared to those of Sumedang accessions with black and brown testa.Keywords: early maturity, leaf shape, pod, seedling emergence, testa color

Abstract

ABSTRACTPhysiological and biochemical changes in seeds indicates levels of viability and vigor during deterioration. The aims of the research were to study the patterns of biochemical changes in soybean seeds and its relationship to seed vigor during storage under controlled conditions. The experiment was arranged in a completely randomized design using two varieties as a factor which was nested into storage period and replicated four times. Two varieties were Gepak Kuning and Mallika, stored in controlled condition at temperature of 19-22 °C and 64-67% of relative humidity for six months. The seeds were evaluated for protein, peroxide value, electrical conductivity and seed viability. The exponential regression analysis was used to determine the patterns of biochemical changes of each soybean varieties during the storage period. The results showed that the biochemical behaviour of soybean seeds stored under controlled conditions for 24 weeks following the exponential equation of y = a + b expcx, which a, b, and c were constants that has different value for each variety. Electrical conductivity and peroxide value could be used as indicators of seed vigor during storage under controlled conditions for 24 weeks. Seed storage under controlled conditions are to maintain seed vigor >80% up to 12 weeks for Mallika and 24 weeks for Gepak Kuning with low oxidative process and less membrane damages.Keywords:deterioration, storability, vigor
