Reduced seedling growth is a consequence of seed deterioration. The heterotrophic seedling growth can be considered as the product of three components: (1) initial seed weight, (2) the fraction of seed reserves which are mobilized, and (3) the conversion efficiency of mobilized seed reserves to seedling tissues. It is not clear which of these component (s) is affected by seed deterioration. To ...

The impact of chemical desiccation on yield showed contrasting results depending on seedmoisture content at the time of application. Its effects on seed deterioration are still unknownand could be modified by seed composition. Objectives were to evaluate the impact of chemicaldesiccation on: i) hybrid sunflower seed yield and composition at harvest time, ii) seeddeterioration during long-term s...

abstract seed deterioration of seed is one of the most important limiting or even hindering factors in germination. the main purpose of this study was to determine the effects of salicylic acid and gibberellic acid hormonal on improvement and prevailing seed deterioration in two sesame cultivars. this studywere carried out at the department of agronomy and plant breeding seed laboratories of co...

Abstract The fundamental deteriorative processes that lead to loss of seed viability contrastingly vary between desiccation insensitive (orthodox) and sensitive seeds (recalcitrant). Orthodox which undergo maturation drying are bestowed with protective mechanisms guard the against deterioration. They include accumulation antioxidants, non-reducing sugars, proteins such as late embryogenesis abu...

seeds deterioration is a natural phenomenon that occurs in all seeds and leading to gradual decline of seed viability during storage. however, the rate at which seeds age depends upon their physiological status, genetic constitution and storage conditions. in the present study we the examined relationship between accumulation of reducing and non-reducing of sugars, soluble protein, the activity...

deterioration of seed is one of the most important limiting or even hindering factors in its germination. an evaluation and understanding of the factors responsible for/ and enhancing seed deterioration is of paramount importance. the main aim of this study was to determine the effects of seed deterioration on its germination and as well on the activities of antioxidant enzymes in canola culitv...

this experiment was conducted in safi abad agricultural research center of dezful in order to study the effect of seed deterioration and plant density on germination, seedling establishment, yield and yield components of hull-less barley with in 2011- 2012. treatments included three levels of seed deterioration: (control, 72 and 96 hours) and five plant densities (100, 150, 200, 250 and 300 pla...
