1. Performance of wheat varieties grown from seeds with different vigor levels
ABSTRACT The objective of this study was to evaluate the performance of wheat plant grown from seeds with different vigor levels. The experimental design was randomized blocks in a 3 x 3 factorial design (cultivar x vigor level) with four replications. The wheat cultivars were Tbio Toruk, Tbio Mestre and Tbio Iguaçu. The classification of vigor levels was

2. Quality of sunflower seeds in function of thickness classification and sowing under speed variation of the seeder-fertilizer
ABSTRACT The objective was to evaluate the quality of sunflower seeds classified according to their thickness and passed through the seeder-fertilizer dosing system under variation of the travel speed. A lot of M734 was classified by thickness passing the seeds through a set of oblong-hole sieves and two thicknesses were selected. A portion of the seeds with

3. Viability of Italian ryegrass (Lolium multiflorum) seeds under application of synthetic auxin herbicides
ABSTRACT Italian ryegrass (Lolium multiflorum) is one of the main weeds in the wheat crop, and the application of synthetic auxin herbicides has the potential to reduce seed viability, therefore, restricting the input into the seed bank. The objective was to evaluate the effects of synthetic auxin herbicides applied at different growth stages on germination,

7. Germination and vigor of soybean genotypes seeds under saline stress
RESUMO A soja destaca-se entre as culturas com maior aplicação da transgenia, principalmente para tolerância a herbicidas, pragas e doenças, mas são escassos estudos sobre estresse salino em plantas geneticamente modificadas. O objetivo desta pesquisa foi avaliar a tolerância ao estresse salino de genótipos de soja, tradicionais e geneticamente modifi

8. GERMINATION OF CACTUS SEEDS UNDER SALINE STRESS
RESUMO As sementes de cactáceas que ocorrem em florestas tropicais sazonais secas estão sujeitas a múltiplos estresses, a exemplo do estresse salino, que limita a embebição e, consequentemente a germinação. Assim, objetivou-se comparar o desempenho germinativo de sementes de Cereus jamacaru subsp. jamacaru e Pilosocereus pachycladus subsp. pernambucoe

9. Physical and physiological quality of rice seeds in function of drying temperature and storage
ABSTRACT The objective with the work was to evaluate, during storage, the rice seeds physical and physiological quality, cultivar IRGA 424 RI, dried with different drying air temperatures. For such, rice seeds were harvested with a moisture content of 22%. Then, they were subjected to drying in a cross-flow dryer, operating in an intermittent system and usin

10. Seed priming with seaweed extract mitigate heat stress in spinach: effect on germination, seedling growth and antioxidant capacity
ABSTRACT Spinach seeds are sensitive to high temperatures during germination and plant growth. It is known that seed priming with water or with seaweed extract (SWE) may enhance germination and seedling growth. The objective of this study was to evaluate the effects of seed priming with SWE (Ascophyllum nodosum) on the germination, seedling growth and antiox

11. MINI-CUTTINGS TECHNIQUE FOR VEGETATIVE PROPAGATION OF Dalbergia nigra
ABSTRACT The usual propagation method for Dalbergia nigra is via seedings; however, the seasonal supply has a variable quantity of seeds which limits the continuous production of seedlings. Therefore, the objective of this study was to establish a vegetative propagation protocol via mini-cuttings technique for D. nigra from juvenile shoots obtained from seed

12. Seed quality of 22 quinoa materials (Chenopodium quinoa Willd.) from the department of Boyacá
ABSTRACT Chenopodium quinoa Willd. is a pseudocereal with seeds that are a rich source of vitamins and minerals. However, there are few studies on quinoa seed quality, especially for the Colombian germplasm. So, the objective of this research was to determine the quality of 22 quinoa materials from the Department of Boyacá by evaluating the physical (color,
