Abstract

The fluctuations in seed food reserves can trigger a cascade of physiological and biochemical events that ultimately manifest as discernible changes in seed morphology and anatomy.  The purpose of this research was to evaluate seeds morphology, anatomy, and quality of Musa balbisiana “Klutuk NTT” and Musa acuminata “Sumatrana” accessions and their storability. Morphological evaluation included seed size and the weight of 100 grains. Anatomical evaluations were carried out for seed structure. The seed quality of the Klutuk NTT banana accessions was observed after being stored for 5, 25, and 41 months, while the Sumatrana banana accessions were observed after being stored for 5, 23, and 41 months. The Klutuk NTT seeds are sized 4 mm to 5.8 mm, while Sumatrana seeds are sized 4 mm to 5 mm. The Klutuk NTT and Sumatrana seeds had a seed coat, endosperm, embryo, micropyle, inner and outer integuments, chalazal, and operculum. The embryonic structure of both Klutuk NTT and Sumatrana seeds exhibited an inverted T-shape. After storage, the two accessions showed significant differences in moisture content, germination rate, vigor index, and seedling growth performance. The Klutuk NTT accessions demonstrated a significant increase in moisture content, germination rate, vigor index, and seedling emergence uniformity, suggesting improved seed performance after storage. In contrast, the Sumatrana accessions showed a significant decline in all measured parameters, except for moisture content. These results suggest that the Klutuk NTT accession may possess a physiological seed dormancy mechanism. Keywords: Banana; germination; true seed; viability; vigor

Abstract

Seed vigor reaches a maximum at physiological maturity and decreases during storage. This study aimed to determine the physiological maturity and enhance the storability of sorghum seeds. Experiments were conducted at BRIN Lebak-Bulus from March 2023 to March 2024. The initial experiment employed a two-factor randomized complete block design, incorporating five sorghum varieties and five seed maturity levels. The second experiment used a complete randomized design with two factors (nest: temperature storage 18 °C and 26 °C, and nested: combined seed moisture content (MC) 10-11% and 12-13%, and storage period (1-24 weeks). The results indicated the seed physiological maturity stages of the five sorghum varieties were: Numbu 46 days after anthesis (DAA), Super-1 39 DAA, Bioguma-1 51 DAA, Samurai-2 55 DAA, and Pahat 40 DAA. The Numbu stored at 18 °C, 10-11% MC had storability up to 24 weeks (72.3% germination) and at 18 °C, 12-13% MC up to 20 weeks (72.3%), while at 26 °C, 10-11% MC had storability up to 18 weeks (71.3%) and 26 °C, 12-13% MC up to 22 weeks (70.3%). The Bioguma-1 and Samurai-2 seeds were suspected of having after-ripening dormancy. From the beginning until 24 weeks, they did not deteriorate, although the viability was below 70%.

Abstract

Bambara groundnut (Vigna subterranea (L.) Verdc) is recognized for its nutritional benefits and ability to improve soil fertility through nitrogen fixation. This study evaluated growth performance, nitrogen dynamics, and seed quality across six landraces: Tasikmalaya, Sukabumi, Sumedang, Small Sumedang, Bogor, and Gresik. The experiment was conducted at IPB University’s Sawah Baru experimental field from July 2022 to March 2023. The experiment used a randomized complete block design with four replications. The measured variables were petiole length, number of petioles, number of leaves, leaf greenness, plant dry weight, nitrogen content, nitrogen uptake in roots, petioles, leaves, and pods, protein content in pods, and seed quality. Results showed significant variation among landraces. Gresik exhibited superior vegetative growth and dry biomass, while Tasikmalaya had the highest pod nitrogen (4.58%) and protein content (28.03%), indicating efficient nitrogen assimilation. Nitrogen analysis revealed distinct uptake patterns across landraces, particularly with Gresik, where a rapid increase in nitrogen suggests that this landrace is well-suited to environments where nitrogen is efficiently fixed and mobilized toward reproductive growth. Sukabumi and Bogor showed the highest germination rates (94%), and Bogor and Gresik had the highest vigor indices (76% and 72%). Overall, Gresik is recommended for balanced performance in growth and seed vigor, while Tasikmalaya is optimal for protein yield and nitrogen use efficiency.

Abstract

Foxtail millet is annual grasses with grains that are smaller than those of sorghum, rice, and wheat, and is considered one of the minor economic crops but with nutritional values similar to other major food crops. The development of millet as major cereal crop is considered challenging due to the low quality of its seeds, and studies have been conducted to improve millet’s seed quality. We conducted this study to determine the harvesting criteria of foxtail millet seeds based on the change in color of the panicles. We also wanted to determine the drying treatment, and evaluate the relationship between the position of the seed on the panicles and the seed viability and vigor. The first experiment was arranged based on a completely randomized design with panicle color as the first factor (green, yellow 75%, and brown) and drying time as the second factor (0 hours, 24 hours, 48 hours, 72 hours). The second experiment was arranged in a completely randomized design with seed position as the main factor (base, middle, tip). The study was conducted on two genotypes of millet, i.e. “BOTOK 4” and “BOTOK 10”. The highest seed quality of “BOTOK 4” and “BOTOK 10” genotypes were obtained when the panicles were brown and dried for 72 hours; the seed chlorophyll content was the lowest and water content was 8.88%, with the highest viability and vigor, i.e., germination rate of 88.3%-90%, maximum growth potential of 92%-95.3%, normal sprout dry weight 596-620 mg, vigor index of 33.6% - 21.6%, and growth rate of 18.2%-17.1% etmal-1. The highest seed viability and vigor in “BOTOK 4” genotypes were obtained from the base position, i.e., 78.7% germination rate, maximum growth potential of 83.7%, vigor index of 56.5%, growth speed of 19.6 etmal-1, normal sprout dry weight of 48 mg, radicle length of 3.3 cm) and “BOTOK 10” genotypes from the middle position with 91.5% germination, maximum growth potential of 97.2%, vigor index of 21.7%, growth speed of 17.0% etmal-1, and normal sprout dry weight 61 mg.

Abstract

Ground cherry (Physalis peruviana) seeds have a period of dormancy after ripening. A study was conducted to understand the mechanism of dormancy, the duration of after ripening persistence, and to determine the effective methods to break dormancy. The study was conducted in an experimental field at Ciwidey, West Java, Indonesia, and the Seed Testing Laboratory, Faculty of Agriculture, Department of Agronomy and Horticulture, IPB University, in February to November 2020. The first study examined the effects of the storage temperatures, i.e. 20 ±2 oC and 25 ± 2oC, and the seed maturity stages, i.e. 49 days after anthesis (DAA), 58 DAA and 62 DAA. Several methods to break seed dormancy were tested, i.e. soaking seeds for 24 hours in distilled water, in 0.5% or 1% KNO3 and, 50 ppm GA3. The results showed that the seed dormancy was broken at 7 weeks after treatment, indicated by seed germination of >80%. The ABA levels of the seeds declined from week 0 to week 11, and the seed ABA and GA reached a balance from week 7 to week 11. Seeds treated with KNO3 or distilled water break dormancy after 8 weeks. The most effective treatment to break seed dormancy is the use of exogenous hormone GA3 at 50 ppm, with seed germination of >80% at week 5.

Abstract

Maize is a significant food crop consumed in numerous countries worldwide. Increasing the yield potential of maize can be achieved through the breeding of high-yielding hybrid varieties. The objectives of this study were to assess the performance of hybrid means and parent combining ability for grain yield and other agronomic traits using a line x tester mating design. The study took place at the Gunung Gede Experimental Station of IPB University, Bogor, from June to October 2022. The experiment was conducted using a randomized complete block design with a single genotype factor and three replications. Twenty-two hybrids were utilized as genetic materials, including 20 hybrid candidates and two check varieties. Six maize lines (H1, L26, Nei, P2B, and P42) were employed as line parents, while L15 and P10 were used as tester parents in the line x tester analysis. The neighbor-joining tree analysis indicated that the female parent has a significant influence on the agronomic and yield performance of the hybrids. Correlation analysis revealed that the yield is more strongly influenced by ear diameter rather than ear length, and it is more affected by the number of kernel rows than the number of kernels per row. Three selected hybrids with favorable traits were Nei x B1, L15 x L26, and L26 x P10. The parent L26 demonstrated relatively good general combining ability for yield and may be considered for future maize breeding program.
