In order to investigate genetic diversity and heritability of some morphological traits in five bread wheat (Triticum aestivum L.) cultivars, two separate experiments were conducted based on randomized compeletly blocks design (RCBD) with 3 replications under stress and normal conditions. The results showed that differences between cultivars were significant for the majority of traits in both c...
The genetic control of root weight, root volume and root to shoot weight ratio was studied in peas (Pisum sativum L.) at flowering. The four populations used were developed from crosses between lines and cultivars differing in size of the root systems. Plants of the F 1, F 2 , backcross and parental generations were evaluated in pots filled with soil: sand mixture, in a completely randomized de...
in order to study the effect of soil compaction on root and shoot growth of wheat plants (shahriar variety), a greenhouse pot experiment was conducted in guilan university. the study design was factorial with completely randomized in three replications. treatments included three compaction levels; (normal compaction, compaction of ten percent and twenty percent) and two type of soil texture (cl...
In order to assess the effect of salinity on root traits and yield of two wheat cultivars, an experiment was conducted in Agricultural, Medical and Industrial Research School, Nuclear Science and Technology Research Institute, Karaj, Iran, using factorial experiment based on complete randomized design with 3 replications. The first factor included sensitive wheat cv. (Tajan) and tolerant cv. (B...
Abstract In order to investigate the effects of nano silver and multi wall carbon nanotube levels on some morphological and physiological traits of faba bean the present study was done. This factorial experiment was conducted in a completely randomized design with three replications and two treatments with four concentrations (0,100,200 and 300 mgl-1). The results showed the total number o...
abstractin order to evaluate the effect of vermicompost and humic acid on quantitative and qualitative traits of sod turf, a factorial experiment based on completely randomized design with three replications was established in research farm in shahrekord university. treatments were vermicompost (zero, 5, 10 and 15 v/v percent) and humic acid (zero, 150 and 250 g/m2), respectively. some traits s...
root rot disease of broad-bean caused by fusarium solani is a serious disease of this crop. due to high cost and difficulty of the disease control, interaction between root nodulating bacteria and fusarium. solani were evaluated to use for disease management. broad-bean root nodulating bacteria were isolated and their interaction with f. solani was investigated in culture medium in a completely...
the treatment of in completely formed pulpless teeth has presented considrable problems. these teeth have wide open apexes and the walls of the root canal diverge toward the apical tissues. mechanical preparation cannot be done in the normal manner beacause of the large initial size and the taper of apical part of the canal , a mechanical stop cannot be produced at the apex of the canal and , t...
To evaluation of genetic parameters of rooting traits in 50 doubled haploid barley lines, a factorial experiment based on CRD was carried out at the agronomy lab of the Zanjan University Analysis of variance showed significant differencesfor all rooting traits:material transfering speed, germination percent, angle, diameter, fresh and dry weight, surface area, cumulative length, the length of t...
