Aging in Orthodox Seeds is a Problem
نویسنده
چکیده مقاله:
Seed deterioration is loss of seed quality, viability and vigor due to effect of adverse environmental factors. Many of our crops are reproduced through seeds, and throughout the world large quantities are produced, stored and transported. Seed ageing during storage may cause retardation of field establishment, and may eventually result in seedling abnormalities or even failure of emergence. During storage in gene banks, seed ageing may result in loss of genetic diversity. Extending and predicting the longevity of stored seeds is therefore highly relevant from a biodiversity as well as from an economic and social point of view. Seed rich in lipids has limited longevity due to its specific chemical composition. During storage of oily species declining trend of total oil content and seed germination can be observed. A fatty acid composition is the most important factor which determines oils susceptibility to oxidation Regardless of the problems which can be encountered due to the lack of space with favourable conditions, one must always keep in mind that seed is a living organism in which many biological processes, which can damage the seed and reduce its quality, take place, especially when the oily seed is in question

متن کاملThe expression of desiccation-induced damage in orthodox seeds is a function of oxygen and temperature
From the premise that desiccation-induced damage is associated with a free-radical mechanism of injur\. we address the hypothesis thai expression of desiccation damage is dependent on metabolism. The effects of temperature and O, concentration on the expression of damage were studied in germinating bean [Phaseoius vuigaris L. cv. Pole Kentucky Wtinder) axes and maize {Zea mavs L. cv. Kelvedon G...
متن کاملOrthodox Seeds and Resurrection Plants: Two of a Kind?[OPEN]
Although staple crops do not survive extended periods of drought, their seeds possess desiccation tolerance (DT), as they survive almost complete dehydration (desiccation) during the late maturation phase of development. Resurrection plants are plant species whose seeds and vegetative tissues are desiccation tolerant. Vegetative DT first arose with the transition from aquatic to terrestrial lif...

متن کاملCryopreservation of dormant European ash (Fraxinus excelsior) orthodox seeds.
We investigated the sensitivity of dormant Polish-provenance Fraxinus excelsior L. seeds to extreme desiccation and liquid nitrogen (LN, -196 degrees C). Germination and seedling emergence tests revealed that the critical water content (WC) of the desiccated seeds was 0.04-0.06 g H(2)O g(-1) dry mass, g g(-1) (0.04 g g(-1) in the germination test and 0.06 g g(-1) in the seedling emergence test)...
