in this study, the effects of different concentrations of bulk and nano-sized ag on seed germination and seedling growth of canola were investigated in a randomized completely design with four replications. the experimental treatments included four concentrations of bulk agno 3 (10, 100, 500 and 1000 ppm), four concentrations of nanosized ag (10, 100, 500 and 1000 ppm), and the control without ...
considering forage grass species, germination is one of the important stagesconcerning the growing stage that is often influenced by environmental stresses,particularly salinity and drought stresses. thus, this study aims to assess the effects ofsalinity and drought stresses on germination characteristics and seedling growth of desertwheatgrass, agropyron desertorum (fisch. ex link) schult. in ...
Experiments were conducted to test several methods for estimating low temperature thresholds for seed germination. Temperature responses of nine weeds common in annual agroecosystems were assessed in temperature gradient experiments. Species included summer annuals (Amaranthus albus, A. palmeri, Digitaria sanguinalis, Echinochloa crus-galli, Portulaca oleracea, and Setaria glauca), winter annua...
Extended abstract Introduction: Today, various technologies have been developed to improve seed quality with the aim of increasing the percentage, speed and uniformity of germination and better seedling establishment under different environmental conditions. One of these technologies is seed pre-treatment or seed priming. In this regard, some studies confirmed that pre-treatment of seeds with ...
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...

in conventional agricultural systems application of fungicide and pesticides for seed treatment had been extended in wide range. this study was conducted to evaluate the effects of seed treatment on seed vigor indices on back cross roshan of wheat cultivar in vitro status during 2007. the experiment was done in a completely randomized factorial design with eight replications. treatment were inc...
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...
Germination is a key process in plants' phenological cycles. Accelerating this process could lead to improvment of the seedling growth as well as the cultivation efficiency. To achieve this, the effect of microwave frequency on the germination of rice seeds was examined. The physiological feedbacks of the MR 219 rice variety in terms of seed germination rate (GR), germination percentage (GP), a...
In order to assess seed deterioration of soybean at Ardebil province, this study was conducted as a factorial experiment based on randomized complete block design in 2014. The treatments consisted of germination ability, seed moisture content and seed storing conditions. Germination ability treatment was concluded of three germination levels: 80%, 85% and 90%. Also, three rates of seed moisture...
