Influences on viability and germination of seeds have been studied intensively for many years, particularly for the numer-ous commercially important agricultural, ornamental, and timber species. High germinating seed lots may differ substantially in field emergence when sown at the same time in the same field, and/or may differ in performance after storage in the same environment or transport t...
antioxidant activity of aerial part of cytisus scoparius, link (family leguminosae) was studied both by in vitro and in vivo models. different concentrations of different extracts of chloroform, ethyl acetate, methanol and hydroalcoholic extracts of plant were investigated for in vitro antioxidant activity using the thiocyanate method. the hydroalcoholic extract exhibited highest inhibitory act...
nowadays, technical terminology translation plays an important role in human life. specific groups of people all over the world refer to learn these terminologies in order to be familiar with a subject and improve their knowledge in that domain. on the other hand, saving the technical translation equivalent is a particularly salient challenge for technical translators. the present study was con...
To study the effect of Piriformospora indica and paclobutrazol (PBZ) as a plant growth regulator for inducing cold stress tolerance in green beans plant (Phaseolus vulgaris L.), a greenhouse experiment was performed as a factorial arrangement based on completely randomized design with three replications. Treatments consisted of three cold stress levels (control, three and six days cold stress a...
to study the effects of sowing dates on seed germination and on seed vigor of 12 spring rapeseed cultivars, an experiment was performed in years 2005-2006. during the first year, 12 cultivars of spring rapeseed were planted in the research field of seed and plant improvement institute, karaj, iran. during the second year, standard germination test was conducted to study the performance of the s...
Extended abstract Introduction: Using of plant growth regulators is one of the methods can improve plant growth against environmental stresses such as salinity. Salicylic acid plays an important role in physiological processes regulation, including germination. Today, using of growth promoting bacteria has been increased and it causes to raise the seed vigor, uniformity, germination percentage...
Extended abstract Introduction: Heavy metals pollution is one of the most important environmental problems. This type of metals with accumulation in the food chain has a lot of human and animal hazards. Among heavy metals, lead is considered to be the most dangerous of heavy metals in the environment, which is contaminated with the environment through the lead-acid battery industry, paint addi...
Although seed vigor is a complex physiological trait controlled by quantitative trait loci, technological advances in the laboratory are being translated into applications for enhancing seed vigor in crop plants. In this article, we summarize and discuss pioneering work in the genetic modification of seed vigor, especially through the over-expression of protein L-isoaspartyl methyltransferase (...
The present study investigates the influence of an organophosphorus pesticide, namely Dimethoate, and cadmium on biomarkers of the green alga, Spirogyra sp., in a 14-day experiment. For so doing, it has exposed Spirogyra sp. to 0.0, 100, 200, and 400 mg L-1 of Dimethoate and/or 1 mg L-1 of cadmium chloride (CdCl2) to observe a reduction in chlorophyll a and b level in Spirogyra sp., exposed to ...
