a better understanding of the factors influencing the germination of weed seeds could facilitate the development of more effective cultural weed management practices. the aim of this research was to determine the effects of environmental factors on seed germination of cutleaf groundcherry (physalis angulata l.). results showed that application of gibberellic acid (ga3) was effective treatment f...

quinoa (chenepodium quinoa willd) is a grain-like crop which has a high production potential in iran. due to its seeds high nutritional value, it is compared with milk by the fao. in order to study the effects of temperatures on seed germination of quinoa seeds under salinity stress conditions, an experiment was conducted in seed lab of the university of tehran in karaj. temperatures regimes in...

the present study was aimed to investigate the effects of titanium dioxide nanoparticles (nano-tio 2 ) on wheat ( triticumaestivum l.) plants cv. parsi. the experimental treatments included seven concentrations of nano- tio 2 (10, 100, 1000, 1200, 1500 and 1700 ppm nano-tio 2 and control (without any tio 2 ). the results showed that among the wheat germination indices, germination rate and weig...

germination is series of biochemical reactions that depends mainly on temperature and moisture. therefore, seed germination rate of lemon balm (mellissa officinalis l.) were evaluated in temperatures of 20, 23, 25,27, 30 and 32ºc and water potentials of 0, -0.2, -0.4, -0.6 and -0.8mpa. according to the results, germination temperature window was not very wide in a way that germination temperatu...

Germination experiments with specific germination mutants of Bacillus subtilis, including a newly isolated mutant affected in pressure-induced germination, suggest that a pressure of 100 MPa triggers the germination cascades that are induced by the nutrient germinant alanine (Ala) and by a mixture of asparagine, glucose, fructose, and potassium ions (AGFK), by activating the receptors for alani...
