Abstract

Taro is a promising food crop that can be developed as a significant source of carbohydrates; however, a major obstacle is the unavailability of high-quality planting materials. Due to the difficulty in obtaining seeds, taro cultivation generally relies on vegetative propagation materials such as cormels, cormlets, and stolons. The advantage of using vegetative propagation material is that it retains the same characteristics as the parent plant. This research aimed to evaluate the quality of various types of cormels as taro planting material, study the potential of different types of cormels on the growth and production of taro plants, and investigate the growth, development, and time required to produce cormels from various types of cormels and their potential in cormel seed production. The research consisted of two experiments: the first experiment evaluated the quality of several types of cormels from two taro accessions (S24 and S28) using a completely randomized design with two factors (accession and types of cormels—primary, secondary, and tertiary), while the second experiment studied the growth and development of cormels from various types of cormels. The best quality seeds were obtained from primary cormels directly attached to the main tubers, with the germination rate highest for primary cormels at 53.25%, followed by secondary cormels at 51.59%, and tertiary cormels at 39.42%. Accession S24 showed a faster emergence rate (30.26 days) compared to S28 (58.08 days), and in S24, there was no significant difference between types of cormels for this parameter. In contrast, in S28, primary cormels had a significant emergence advantage (33.65 days) over secondary and tertiary cormels (62.57 and 78.02 days, respectively). Additionally, primary cormels were formed 8 weeks after planting, while secondary and tertiary cormels appeared 12 weeks after planting. These findings suggest that primary cormels should be prioritized for use in taro propagation to improve growth, development, and yield, highlighting their potential in cormel seed production and offering a viable solution to the challenge of seed availability in taro cultivation.

Abstract

Topographical tetrazolium (TZ) pattern to determine viability, vigor and field stand on soybean seeds cv. Burangrang was studied.  Laboratory test for standard germination, vigor index, speed of germination, accelerated aging, seedling growth rate and field performances were performed on five lots (A,B,C,D,E) of soybean seeds.  The viability and vigor categories of each pattern were determined by Root Mean Square (RMS), regression, and correlation analysis.  Ten topographical patterns were recognized. The laboratory test results and field performances were compared with topographical pattern. Combination of patterns 1,2,3,4 (embryonic axis and cotyledon completely and/or gradually stained) selected as viable category as it gave the least RMS value, the highest determination (R2) and correlation (r) coefficient with standard germination (RMS=6,46; R2=0,37; r=0,61). Combination of patterns 1,2,3 (embryonic axis and cotyledon completely stained) selected as vigor category as it gave the least RMS value, the highest R2and r with relative speed of germination (RMS=7,96; R2=0,44; r=0,66), vigor index (RMS=6,66; R2=0,36; r=0,6), field emergence (R2=0,79; r=0,89) and field stand (R2=0,65; r=0,80). The combination of patterns 1,2,3 is recommended for estimating field emergence and field stand.   Key words :  Tetrazolium, topographical pattern, viability, vigor, accelerated aging, field stand, soybean seed.

Abstract

The objective of this trial was to determine the effect of the best  packaging material, storage room condition and storage period for the seed viability of caisin. The trial was conducted at the seed laboratory of the Department of Agronomy and Horticulture, Faculty of Agriculture, Bogor Agriculture University in March- October 2005. The experiment was arranged in completely randomized design with three factors. The first factor was packaging materials (paper, polyethylene and aluminum foil); the second factor was storage room conditions (ambient room, Air Conditioned (AC) room and refrigerator); the third factor was storage periods (0, 3, 6, 9, 12 and 15 weeks). The result of this research showed that packaging materials gave significant effect on the dry weight of normal seedling. Storage periods gave very significant effect on germination percentage, dry weight of normal seedling, maximum growth capacity, and vigor index. The interaction between packaging materials, storage room conditions and storage periods gave very significant efflect on germination rate. Based on the dry weight of normal seedling, polyethylene and aluminum foil package gave the same result, on the other hand paper package gave the lowest dry weight of normal seedling than that aluminum foil package.  Based on the germination percentage, dry weight of normal seedling, maximum growth capacity, and vigor index the seed viability of caisin did not  decrease, even after 15 weeks of storage period.   Key words : Packaging materials, storage periods and seed viability

Abstract

Seed quality is an important factor in rice production. Bacterial leaf blight (BLB) caused by Xanthomonas oryzae pv. oryzae (Xoo) is a seedborne disease of rice that cause serious yield losses in Indonesia. Experiments were conducted at the Laboratory of Rice Research Babakan, IPB, Bogor; Laboratory of Seed Science and Technology at IPB, Bogor; and the Laboratory of Seed PT. EWSI, Purwakarta, from April to August 2011. The objective of this research was to determine the effectiveness of coating Xoo contaminated rice seeds with biological agents on plant growth and crop yield. The experiments were arranged in a randomized complete block design with one factor (seed coating treatment),i.e. T0 = negative control, healthy seed; T1 = positive control, the seeds contaminated with Xoo; T2 = P. diminuta A6 and B. subtilis 5/B; T3 = alginate 3% + 1% peat + P. diminuta A6 and B. subtilis % 5/B; T4 = arabic gum 3% + 1% gypsum + P. diminuta A6 and B. subtilis 5/B; T5 = CMC 1.5% + 1% talc + P. diminuta A6 and B. subtilis 5/B, and T6 = bactericide streptomycin sulfat 4%. The results showed that seed coating treatment with with 3% alginate + 1% peat + P. diminuta A6 + B. subtilis 5/B was the best treatment based on the percentage of full and empty grain weight per panicle, and the percentage of number of full and empty grains per panicle.

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

ABSTRACTThe aims of this research on Reutealis trisperma seed were to know 1) seed harvest maturity level based on physiological and biochemical changes; and 2) seed recalcitrancy based on critical moisture content and storability in two storage temperatures. The research was conducted at Leuwikopo Seed Science and Technology Laboratory, from February 2012 to January 2013. There were three experiments, i.e. I. Effect of seed maturity level on seed viability and vigor (randomized completely block design, 3 seed maturity level, 3 replications); II. Determination of seed critical moisture content, used two methods, i.e. 1) fan drying and 2) air drying (completely randomized design in each drying methods, 3 replications); III. Effect of temperature and period of storage on seed viability and vigor (nested design, first factor was 2 storage temperature and the second factor was 7 storage periods, 3 replications). The result showed that seed physiological maturity achieved in 28 weeks after flowering with morphological criteria were brownish fruit, soft fruit exocarp, brown seed testa; physiological criteria was germination percentage 76-80% and biochemical criteria was carotenoid content 0.62 µmol(g FW)-1. Carotenoid content can be used as biochemical indicator to determine fruit maturity and significantly correlated with moisture content, seed dry weight and germination percentage. Critical moisture content were 8.2-10.9%. These data suggested that seeds could be classified as intermediate. R. trisperma  seeds could be stored for three weeks in temperature 19-28 oC and RH 50-70%, with 12% moisture content used polypropilen plastic bag Keywords: carotenoid, critical moisture content, desiccation, Reutealis trisperma

Abstract

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
