ABSTRACT: Of the natural pastures grown in southern Brazil, those of genus Paspalum are most important. One factors that hinder their cultivation is availability quality seeds, often compromised by presence fungi. This study determined vitro sensitivity guenoarum ecotype azulão seed-associated fungus to certain fungicides and measure efficiency chemical treatments for fungal control seed physio...

Abstract: Simira gardneriana (Rubiaceae) is a newly discovered tree species endemic to the Caatinga. For this reason, studies aimed at propagation, seed and seedlings analysis are essential for morphology, identification, classification, conservation. Our objective was characterize seeds, morpho-physiology of germination seedling establishment S. gardneriana. Therefore, we performed physical, b...

Germination inhibitors, which inhibit the germination of seeds, spores and other plant reproductive material, are abundant in kingdom include phenols, cyanides, alkaloids, essential oils, amino acids, etc. These inhibitors can be classified as destructors retarders depending on whether they harm morphology, structure physiology seed. closely related to seed dormancy, exogenous used extend “dorm...

changes in seed dormancy were selected during the domestication of crop plants from wild-plant species, because some features of dormancy that provide ecological advantages presented agronomic disadvantages within a farmed system. seed dormancy varies widely among seed batches, even for seeds of the same genotype, indicating large environmental influences. for genetic studies, it is essential t...

Thioredoxins (Trxs) h, small disulfide reductases, and NADP-thioredoxin reductases (NTRs) have been shown to accumulate in seeds of different plant species and play important roles in seed physiology. However, little is known about the identity, properties, and subcellular location of Trx h isoforms that are abundant in legume seeds. To fill this gap, in this work, we characterized the Trx h fa...

Digestive physiology and movement patterns of animal dispersers determine deposition patterns for endozoochorously dispersed seeds. We combined data from feeding trials, germination tests, and GPS telemetry of Asian elephants (Elephas maximus) to (1) describe the spatial scale at which Asian elephants disperse seeds; (2) assess whether seasonal differences in diet composition and ranging behavi...

A major disadvantage of conventional seed radiography is that the resulting image will not distinguish full-viable seeds from full-nonviable. Empty seeds will imbibe sufficient water to appear full, but these are easily distinguished by radiography before imbibition. Full seeds, both viable and nonviable, have 25 to 35% moisture content when freshly collected. This is sufficient water to confus...

Abstract Seed physiology of 15 Eucalyptus species interest for cut foliage plantations was unknown and therefore evaluated. The viability vigour seeds germination potential determined by using a tetrazolium (TZ) staining test, the results were compared to test. In separate experiment, each lot subjected either 0 or 4-week cold stratification at 4 ± 1 °C investigate their requirement. After stra...

considering the emphasis of islam on the importance of fasting, muslims attempt to fast from dawn until sunset during the holy month of ramadan. fasting is associated with several benefits for normal and healthy individuals. however, it could pose high risks to the health of diabetic patients due to certain physiological changes. this study aimed to compare the physiological changes associated ...
