Stored seeds deteriorate over time and must be regenerated to ensure that the benefits of ex situ conservation are realized. Prediction of seed longevity is based on the seed viability equation. This equation has four constants which are species specific. The aim of this project is the estimation of these constants and prediction of regeneration frequency for Elytrigia elongata, Dactylis glomer...

BACKGROUND AND AIMS Physiological epicotyl dormancy in which the epicotyl elongates inside the seed before the shoot emerges has been reported for only a few tropical rainforest species, all of which are trees that produce recalcitrant seeds. In studies on seeds of Fabaceae in Sri Lanka, we observed a considerable time delay in shoot emergence following root emergence in seeds of the introduced...

canola is one of the most important crops in the world and ranked as the third most important oil seed crop. adverse environmental storage conditions including high temperature and relative humidity could affect canola seed quality. the aim of this study was to evaluate the seed quality of canola seed under various seed moisture content, temperature and storage time using okapi cultivar. also, ...

Changes in ascorbate content and its enzymatic utilization pattern were studied in embryonic axes and cotyledons of sal seeds undergoing rapid loss of viability, at ambient conditions. Ascorbate levels were significantly higher initially in the embryonic axes (0.32 mg/g fresh weight) and cotyledons (0.21 mg/g fresh weight) of freshly mature, relatively hydrated (42.2% moisture content) and 100%...

How the seeds of Delphinium staphisagria promote hair growth in humans is yet to be discovered. This lack of information leads us to the investigation of hair promoting effects of seeds of Delphinium staphisagria in vitro. Extract prepared from the Seed of Delphinium staphisagria (ESDS) - traditionally used for hair loss treatment - was selected and tested for the cytotoxic and angiogenic poten...

Seeds lose their viability when they are exposed to high temperature and moisture content (MC) during storage. The expression and metabolism of proteins plays a critical role in seed resistance to heat stress. However, the proteome response to heat stress in oat (Avena sativa) seeds during storage has not been revealed. To understand mechanisms of heat stress acclimation and tolerance in oat se...

Non-native earthworms have invaded ecosystems around the world but have recently received increased attention as they invaded previously earthworm-free habitats in northern North America. Earthworms can affect plants by ingesting seeds and burying them in the soil. These effects can be negative or positive but are expected to become increasingly negative with decreasing seed size. Orchids have ...
