low seed germination and seedling emergence is one of the main problems in saline areas. seed priming technique has been known as a challenge to improve germination and seedling emergence under different environmental stress. the objective of this research was to evaluate the effect of seed priming with gibberellin, nacl and water on seed germination and seed reserve utilization and germination...

Isabgol (Plantago ovata Forsk) seed germination and emergence in response todrought (Polyethylene glycol 8000) and salinity stress (NaCl), temperature, pH andplanting depth were studied in laboratory and greenhouse experiments. Base,optimum and ceiling germination temperature were estimated as 3.35, 21.24 and35.04 oC, respectively. Isabgol seed is rather tolerant to low water potential and high...

the effect of electromagnetic field was examined on zinnia (zinnia elegans) seeds to enhance seed germination and early growth. the seeds were exposed to four magnetic strengths of 15, 100, 400 and 800 mt in four durations of 30, 60, 120 and 240 min. the experiments were carried out in two forms of laboratory germination and soil emergence. results showed that magnetic field application enhance...

this research was conducted to evaluate the role of drought stress and planting dates on seeds vigour and seedling growth of produced seeds. the experiment was performed in the research field and seed technology laboratory of the department of agronomy and plant breeding, college of aboureyhan in pakdasht in spring 2008. five canola cultivars including licord, opera, modena, elite, sarigol (in ...

laboratory and greenhouse experiments were conducted to determine the effects of drought and salinity stress, temperature, ph and soil depth on rye germination and emergence in gorgan university of agricultural science and natural resources. optimum temperature for germination between 25 to 34.51   oc and base and ceiling temperatures were estimated as 3.3 and 40   oc, respectively. this volunt...

This study was carried out to investigate the effect of hydropriming on seed germination and seedling growth of five different flower seed species (Antirrhinum, Dahlia, Impatiens, Salvia and Zinnia). Hydropriming (20oC, 24 h), surface dried or dried back afterwards, was found to increase germination percentage, seedling emergence and fresh and dry weight. In all species, the maximum advantage i...

abstract germination and emergence of cold tolerant lentil genotypes sometimes experiences low temperatures and variable rainfalls in the fall planting. this study was conducted to evaluate the effects of drought stress on germination stage of lentil genotypes. experiment was carried out with 18 lentil genotypes under five levels of water potential (0 , -0.4 , -0.8 , -1.2 , -1.6 mpa) using peg ...

BACKGROUND AND AIMS The relative importance of pre- and post-germination determinants for recruitment of natural plant communities is rarely explored. An annual plant community on moving sandy land was chosen for a case study. Answers to the following questions were sought: (a) Does recruitment of new individuals within the community of annual plants differ in time and space? (b) Is there spati...

Seed priming is a physiological seed enhancement method. Hydroor osmotic priming can advance germination under adequate moisture conditions. During direct seeding on well-drained paddy and upland fields, rice seeds occasionally encounter low soil moisture conditions. Under these conditions, rice seeds need to undergo rapid germination and secure emergence through improved water absorption capac...
