The viability of seed often decreases during multi-year storage. For seed enhancement technologies (SETs) that apply treatments to native seed prior to sowing in restoration projects, it is important to determine if SETs affect the rate of viability loss in storage to understand if treated seeds can tolerate storage or if they must be sown immediately after treatment. Examining herbicide protection pellet (HPP) seed technology, we conducted germination trials on 10 seedlots of four species to compare three treatments: original bare seed kept in seed storage for 2–3 years, seed retrieved from 2

Seed weight of Abutilon theophrasti Medic, varies among populations and with the light conditions of the parent plants. In this study, the impacts of seed weight variation on seed germination and plant growth were investigated. Variations in seed weight did not result in any significant difference in the germination ability of seeds. The enhanced germination associated with large seeds produced by plants in shaded conditions found in previous studies were more likely the result of interpopulational variation or difference in maternal environments.

Seed cost is a major input expense for the production of kabuli chickpea (Cicer arietinum L.) due to its large seed size. Use of small seeds could reduce production costs because a lower volume of seeds would be needed per unit area. This study determined the effects of seed size, and selective use of small seeds, year after year, on the field performance of kabuli chickpea in Swift Current, Saskatchewan from 2000 to 2003.

To ensure the quality and flavor of malts and beers, beer brewers will strictly check the appropriate varieties of barley seeds during the malting process. There are wide varieties of barley seeds with small sizes and similar features.

Abstract Male asparagus (Asparagus officinalis L.) plants generally have higher yields and live longer than female plants; therefore, are preferred by growers. Another advantage of male plants is the lack of seeds, which, on female plants, produce volunteer seedlings regarded as a weed problem in commercial fields. Perhaps the most important long-term advantage of a male hybrid is that growers are unable to produce their own seed and thereby obliterate the original “cultivar.” The production of seed by growers already has led to the loss of excellent original strains of Martha and Mary Washing

Aims: To achieve sustainable agriculture, it is essential to conduct ongoing research aimed at reducing the reliance on chemical fertilizers. This study investigates the effectiveness of seed priming, either alone or in combination with low doses of fungicides and/or biocontrol agents, to enhance seed quality and to reduce seed infection by improving the rate and uniformity of seed emergence and overcoming diseases. Study Design: Completely randomized design. Place and Duration of Study: Seed Unit, UAS, Raichur, from March 2022 to September 2022. Methodology: Sorghum seeds were surface sterili

SEASONAL PATTERNS OF SEED DISPERSAL IN SOUTHEAST VIETNAM SEA A comparative analysis of flow velocity and seed dispersal patterns in the Southeast Vietnam Sea revealed significant seasonal variations. During the southwest monsoon, flow velocities were substantially higher than those observed during the northeast monsoon. Notably, areas with flow velocities ranging from 0.6 to 1.0 m/s constituted approximately one-third of the simulated region. To gain deeper insights into seed source dispersal dynamics, we employed Delft3D modeling software to simulate continuous seed reproduction over seven-da

It is noted that the main factor in reducing the quality of the lint is its contamination caused by the increased content of crushed seeds. The latter is explained by the mechanical impact on the seed roller from the rigid elements of the working bodies of the linter machine, such as saws, grates and agitator. The magnitude of this impact largely depends on the density of the seed roller itself. In addition, its high density is the cause of additional energy costs for its rotation. To reduce the dynamic loads on the seeds in the roller, an original design of agitator with elastic inclined blad

Studies on the field performance of differentially aged seeds using seed and plant leaf extracts on seed yield and quality of paddy variety IR 20 revealed that the effect of accelerated ageing mimicked the natural ageing as was observed through reduction in germination, seedling length and drymatter production after hydration-dehydration either with water or using blackgram seed leachate (1:1) for 8 and dried back to original moisture content. The effect of ageing could be alleviaed through this treatment and this was reflected on enhancement of plant height, number of tillers/plant, days to 5

Seeds were infected by two methods: (i) spray-inoculation of maize silks during seed development (field-infected), and (ii) soak-inoculation of mature seeds in a spore suspension (laboratory-infected). Plants were grown from infected seeds and assayed for systemic infection by the seed-inoculated strain, determined by vegetative compatibility of recovered isolates with the original strain. The see

Hence, a laboratory experiment was conducted during 2019 in the Department of Seed Science and Technology, Agricultural College and Research Institute, Madurai, Tamil Nadu. The S. nigrum seeds were primed by soaking in different chemicals viz.,GA3 100ppm, Thiourea1%, KNO3 0.5%, Succinic acid 100 ppm, Ascorbic acid 100 ppm, hydro and dry control with soaking durations of 12h and seeds were dried under shade

Seeds play a vital role in the perpetuation of plant species, both in natural environments and agriculture. However, they often face challenges from biotic stresses, such as seed-borne pathogenic fungi. The transgenerational transmission of these seed-borne fungi, along with their dissemination during seed commercialization, can contribute to the emergence of global epidemic diseases, resulting in substantial economic losses. Despite the recognized impact of seed-borne pathogens on agriculture, our understanding of seed–pathogen interactions remains limited. This review establishes parallels b

The rest of the seed was used for fatty acid and glucosinolate analysis by gas chromatography and high-performance liquid chromatography.
