abstract- this experiment was carried out during the growing seasons of 2010 and 2011 at the agricultural research farm of bu-ali sina university, to study the effect of weed competition on subsequent germination and seed vigour of chickpea. 12 weed interference durations were evaluated in a randomized complete block design with three replications. experiments consisted of two sets of treatment...

Extended Abstract  Introduction: Germination is considered the first and most important stage of establishment and consequently, successful competition which is influenced by genetic and environmental factors. Among the environmental factors influencing the germination, temperature and light are the most important ones. Using different models, the germination response of seeds to temperature c...

Salinity is one of the most important ecological stresses which have undesirable effects on seed germination. This study was carried out to evaluate the germination of three species of lawn (Poa pratensis, Lolium perenne, Cynodon dactylon) seeds under salinity stress. The effect of different treatments (Gibberellins 50 mgl-1, 2% CaCl2 and hydroprimig in 24 hours) was evaluated on total germinat...

in order to investigate the germination characteristics and cardinal temperatures of biotype alhaji pseudalhagi, a laboratory experiment was conducted randomized completely design with four replications of 25 seeds. various constant temperatures 5, 8, 10, 15, 20, 25, 30, 35, 40, 45 and 50ºc were considered. the characteristics such as percentage of seed germination, rate of seed germination, th...

Extended Abstract Introduction: Nowadays, due to land use change and destruction of natural resources induced by human activities, attention to desertification has immensely become widespread. One of the most important species for biological rehabilitation of desert areas on a large scale is the hawthorn plant. Hawthorn is a plant belonging to the family Amaranthaceae, the two species of which...

Silvereyes, Zosterops lateralis Latham, commonly feed on kiwifruit rejected for export and either stored in open bins at packhouses or in piles ready to be fed to livestock, and may play a role in the spread of wild kiwifruit in native and exotic forest in the Bay of Plenty, New Zealand. We determined the germination rate and percentage germination of Actinidia chinensis Planch. seed sown (1) a...

DOR: 98.1000/2383-1251.1397.5.101.9.1.1578.1610 Extended abstract  Introduction: Stevia is a perennial short day plant, belonging to the Asteraceae family. It is also called sugar leaf. Poor germination of this plant serves as a barrier for its planation on a large scale, which contributes to its scarcity and expensivenss as a medicinal herb. In many plants, seed germination is sensitive...

to study the effect of harvesting time on soybean seed germination and vigor a factorial experiment with three replications, including of five harvesting time and three soybean cultivars was carried out in the field and glasshouse. the effect of harvesting time on seed germination percentage (in the field, cold test and paper test), seed germination rate, shoot and root weights, 1000-seed weigh...

Seed aging increases activity of reactive oxygen molecules and antioxidant enzymes have a key role against increased oxidative stress which is caused by free radicals. Effect of seed priming on increasing of these enzymes activity and its impacts on seed germination characteristics of deteriorated milk thistle seeds was studied in University of Mohaghegh Ardabili in 2013. Factoral experiment ba...
