in this thesis protic and aprotic ammonium-based ionic liquids were synthesized and their surface tensions were measured in the range of 298-373k. the protics are alkyl ammonium-based ils with the carboxylate (formate, acetate, propionate) anion and aprotics are quaternary ammonium-based ils with bis(trifluoromethylsulfonyl)imide anion. capillary rise method was used for surface tension measure...

The study was conducted over a period of six months from January to June 2004 to explore the effects of different seed treatments on germination and seedling growth attributes of a popular medicinal plant, Horitoki (Terminalia chebula Retz) in the nursery of Chittagong University, Bangladesh. Seeds were subjected to six pre-sowing treatments e.g. control (T ), depulped (T ), depulped and soaked...

Heat stress seriously affects the production of cool-season food legume crops such as garden peas. Seed priming is a widely used technique that increases germination and improves plant growth development, resulting in better field performance higher yield crops. In current study, we investigated three seed treatments—hydropriming (dH2O), osmopriming (2.2% w/v CaCl2), hormopriming (50 mg L?1 sal...

Accelerated aging test to estimate the percentage of emergence are designed to lay the seeds for life, as well as an indicator to determine the power of the seed used. In this study, the effects of aging zero (control), 2, 4 and 6 days on germination index of rapeseed genotypes including Okapi, R15, BAL11, L109, BAL2 Were detected in a factorial experiment based on completely randomized design ...

Priming of seeds by magnetic fields (magneto priming) is proposed as an ecological, useful and low-priced method for improvement of seed germination and plant emergence. In order to evaluate the germination behavior of sesame seeds affected by magnetic fields, an experiment was conducted as a completely randomized design with 22 treatments (non-exposure to magnetic fields (control) and 21 magne...

Seed priming is a method which is a quite effective method for improving germination and seedling establishment. Two separate experiments were performed to determine the best hydro and osmopriming treatments effects on canola‘s seed germination. The experiments were performed in seed technology laboratory of Islamic Azad University, Karaj, Iran, 2014. The first experiment contained three ...

Salinity is the major constraint that decreases yield and production of crops. Wheat has a significant value in agricultural food commodities. The germination growth wheat seedlings are big challenge salt-affected soils. seed priming technique used to mitigate salt stress enhance Therefore, current study was conducted evaluate hydropriming natural plant extract (moringa leaf extract) water on s...

seed reserves are controlled by genetic and environmental condition such as nutrition, temperature, drought stress and light intensity. strong seedling will produce from seeds with high reserves. therefore, in this work that conducted in pot, field(in tabriz university) and lab(in shahrood university of technology) experiments, effect of pre-anthesis nitrogen application and a drought stress du...

The objective of this research was to evaluate the effect of salicylic acid and gibberellic acid on germination characteristics and changes of proline, protein and catalase activity of Brassica napus seedlings under Cu(SO4) stress. The experimental design was factorial with complete randomized design as a base design with 3 replications. The first factor was 4 levels of Cu(SO4) stress (0, 10, 2...
