seeds of most crops including those of range plants follow orthodox behavior. however, these seeds undergo aging even under favorable conditions, so that decreased viability and vigor related parameters are the main characteristics of deteriorated seeds. the effects of hormonal priming with auxin, cytokinin, gibberellin and abscisic acid at 0, 50, 100 and 150 ppm on physiological quality of tal...
Medicinal barberry plants, belong to Berberidaceae family. Seeds of barberry have long period dormancy. Therefore, overcome to seed dormancy and increasing germination rate of seeds due to different methods will be useful. In this regard, two separate experiments were designed. In the first experiment, effect of different levels of Gibberellic acid (0, 600 and 900 mg.l-1 at 8˚C) and temperature...
This study aimed to evaluate the effects of priming on seed germination under salt stress and gene expression in seeds and seedlings of P. angulata L. After priming for 10 days, seed germination was tested in plastic trays containing 15 ml of water (0 dS m-1 - control) or 15 ml of NaCl solution (2, 4, 6, 8, 10, 12, 14 and 16 dS m-1). Fresh and dry weight of shoots and roots of seedlings were ev...
A laboratory experiment was conducted to evaluate the effect of seed priming under salt and drought conditions on seed germination and early seedling development of millet. A factorial experiment (3×2×5) based on completely randomized design with three replications was employed. The first factor was the effect of seed priming (control, hydro priming and KNO3), the second factor was ...
Extended Abstract Introduction: Drought stress, as abiotic and multidimensional stress, has severe effects on plant growth. One of the new approaches in the management of drought stress is the use of nanoparticles. Nanoparticles infilterate the seeds and increase nutrient and water uptake and ultimately, improve germination. The present research was conducted to evaluate the effects of titaniu...
AbstractThis study was undertaken to better understand the probable mechanisms of salt stress tolerance induced by seed priming of salicylic acid (SA) in barley. The barley seeds were pre-soaked by SA or water and then sown under different saline watering regimes including 0.62 (tapwater), 5, 10 and 15 dS m-1 in petri dishes and trend of water absorbing, seedling growth, germination rate and pe...
Seed deterioration as an irreversible physiological phenomenon, have significant effect on seed quality. Increasing and maintaining of seed quality by using methods such as biopriming is important. For this reason a three-factors experiment was conducted on one linseed cultivar (Norman) based on randomized completely design with four replications, in laboratory of Seed Science and Technol...
Regulation of seed germination requires coordinate action by the embryo and surrounding endosperm. We used Arabidopsis thaliana to establish the relative roles of embryo and endosperm in the control of seed germination and seedling establishment. We previously showed that endospermic oil reserves are used postgerminatively via gluconeogenesis to fuel seedling establishment and that lipid breakd...
salinity is one of the important factors that reduce the growth and yield of crops in iran; however, determining appropriate methods for reducing its negative effects is important. in order to study the effects of nutritional condition of mother plant and bacterial biofertilizers seed priming on germination indices of wheat (triticum aestivum l.), in salinity condition, an experiment was conduc...
