Deterioration of sunflower seeds during storage

The speed on deterioration of oil-seeds depends on conditions of the storage environment and on particularities of the species, which include the seed chemical composition. Within this study, the changes on quality of sunflower seeds, stored in different packaging types and environmental conditions, were investigated. The packaging used were multiwall Kraft paper and plastic...

Physiological quality of eggplant seeds with different extraction and drying methods

During seed extraction in fleshy fruits, some procedures are necessary to ensure seed quality and minimize deterioration and microorganism activity; also seeds extracted under moist conditions need special care when drying. The objective of this study was to evaluate the physiological quality of eggplant seeds submitted to different extraction and drying methods. In the first...

Performance of rice seeds treated with zinc, boron, and molybdenum

The objective of this study was to assess physiological quality of seeds and the initial growth of lowland rice seedlings, cv. PUITA INTA-CL, treated with a product based on Zinc, Boron and Molybdenum. The following dosages of product were used: 0 (control), 50, 100, 150 and 200 mL.100 kg-1 seed. A completely randomized experimental design was used, with 10 treatments and four...

Physical and physiological qualities of soybean seed as affected by processing and handling

Seed processing machines remove viable seeds from non-viable seeds and inert materials based on physical characteristics. The objective of this study was to assess the effect of each processing machine alone on the physical and physiological qualities of the soybean seeds. Seed samples of two soybean cultivars - BMX Potência RR and NK 7059 RR - were collected from five machines...

Assessment of the physiological potential of super sweet corn seeds

The assessment of physiological potential is essential in seed quality control programs. This study compared the sensitivity of different procedures for evaluating super sweet corn seed vigor, focusing on the primary root protrusion test. Six seed lots, each of the SWB 551 and SWB 585 hybrids, were used. Seed physiological potential was evaluated by germination and vigor tests...

Morphological characterization and physiological potential of Stenachaenium megapotamicum (Spreng.) Baker seeds

Stenachaenium megapotamicum (Spreng.) Baker is a native species with ornamental potential for use in landscaping and floral arrangements. This study aimed to evaluate germination and storage of S. megapotamicum seeds. In addition, the seeds were characterized morphologically. Germination was tested under constant (10, 15, 20 and 25 °C) and alternating (15-20 °C) temperatures. The...

Seed performance of different corn genotypes during storage

Corn seed producers have shown significant concern about variations in the seed storage potential of different hybrids, which may not perform as desired. The objective of this research was to evaluate the effect of storage conditions on the physiological potential of seeds of different corn genotypes. Three experimental corn hybrids, each represented by three seed lots produced...

Water uptake and pre-germination treatments in macaw palm (Acrocomia aculeata - Arecaceae) seeds

The aims of this study were to evaluate the influence of embryo adjacent tissues in water uptake and treatments to release dormancy in macaw palm seeds. To assess water absorption with or without the opercular tegument (OT), seeds were immersed in water for 0, 12, 24, 48, 72, 96, 120, 168, 240, 360, 480 and 720 hours and the water content of isolated embryos and seeds was...

Activities of α-galactosidase and polygalacturonase during hydration of Dalbergia nigra ((Vell.) Fr All. ex Benth.) seeds at different temperatures

Germination is a process that begins with seed water uptake, stimulating enzyme synthesis or activating enzymes already present. The objective of this study was to evaluate variations in monosaccharide reserves and the activities of the α-galactosidase and polygalacturonase enzymes during the hydration of two lots of Dalbergia nigra (Bahia Rosewood) seeds. Seeds from different...

Viability of Inga vera Willd. subsp. affinis (DC.) T. D. Penn. embryos according to the maturation stage, fungal incidence, chemical treatment and storage

The main strategies for conserving Inga vera seeds during storage consist of their partial dehydration and low temperatures. However, such storage conditions can lead to further deterioration of the seed, either from its own metabolism or the development of microorganisms favored by moisture. In this study, the relationship between fungi and the conservation of I. vera embryos...

Germination of "Solo

The aim of this study was to investigate the effects of some plant hormones on germination of Carica papaya L. seeds of the "Solo" group taken from fruits at maturity stages 3 and 5 (50% and 75% of the fruit skin showing a yellow color). Then, the seeds were subjected to treatments involving different combinations of acid 2-chloroethylphosphonic - (CEPA 0; 5 x 10-7 and 5 x 10-4 M...

Desiccation sensitivity from different coffee seed phenological stages

Maturity stage and drying method are the factors that most influence coffee seed quality. The objective of this study was to assess the physiological quality and investigate the electrophoretic patterns of catalase and endo-β-mannanase enzymes and heat resistant proteins in coffee seeds harvested at different phenological stages and dried under different conditions. Physiological...
