Ageing induces seed deterioration expressed as the loss of seed vigor and/or viability. Priming treatment, which consists in soaking of seeds in a solution of low water potential, has been shown to reinvigorate aged seeds. An experiment was conducted to evaluate the effects of naturally and accelerated aging on seed germination traits and enzyme activities (proxidase, catalase and superoxid dis...

Cadmium (Cd) is considered one of the most toxic heavy metals to living organisms, being very persistent in soil and non-biodegradable, thus posing a long-term hazard plants humans. In recent years, application different molecules at seed level, known as chemical priming, has been studied method improve stress tolerance plants. present study, we tested effect hydro-priming proline priming lettu...

Priming of legume seeds before sowing was performed by Roman farmers in order to increase the germination rate and synchronize germination, as reported naturalist Gaius Plinius Secundus. Several centuries later, this technique is still used for a wide range species. However, measure be successfully production, it necessary find solution successful storage primed seeds. The potential soybean det...

Cbeatgrass (Bromus tectorum L.) has become the dominant species over large areas of rangeland in the Great Basin region of the western United States. Rapid germination at low temperature may contribute to the competitive success of cheatgrass in areas formerly dominated by native sagebrush and bunchgrass species. The objectives of this study were to determine whether seed priming could be used ...

Deterioration of seeds is an important problem leading to low germination and uneven crop establishment causing poor growth productivity. Soil salinity another factor limiting cultivation. Spermidine (Spd) a compound widely reported for diminishing adverse effects salt stress in plants. In this study, the Spd priming on normal deteriorated rice were investigated under during young seedling stag...

Lettuce (Lactuca sativa L.) seeds have poor shelf life and exhibit thermoinhibition (fail to germinate) above ∼25°C. Seed priming (controlled hydration followed by drying) alleviates thermoinhibition by increasing the maximum germination temperature, but reduces lettuce seed longevity. Controlled deterioration (CD) or accelerated ageing storage conditions (i.e. elevated temperature and relative...

Industrial hemp (Cannabis sativa L.) as a grain and fiber crop is experiencing resurgence in North America. Due to governmental prohibition, there has been limited information on regional agronomic production systems including basic seed germination. This study was initiated provide the relationship between temperature germination seed. Germination measured at constant temperatures ranging from...

Seed priming is a technique which is potentially able to promote rapid and more uniform seed germination and plant growth as well. In this regards, the presowing effects of seed priming treatments were investigated on some physiological viz. seed germination, germination rate, radicle elongation, shoot elongation, radicle dry weight, shoot dry weight and vigor index. Seeds were subjected to two...
