A field study was conducted to compare the formationand bacterial communities of rhizosheaths of wheat grown under wheat-cotton and wheat-rice rotation and to study the effects of bacterial inoculation on plant growth. Inoculation of Azospirillum sp. WS-1 and Bacillus sp. T-34 to wheat plants increased root length, root and shoot dry weight and dry weight of rhizosheathsoil when compared to non...

the main objective in sampling is to select a sample from a population in order to estimate some unknown population parameter, usually a total or a mean of some interesting variable. a simple way to take a sample of size n is to let all the possible samples have the same probability of being selected. this is called simple random sampling and then all units have the same probability of being ch...

Effect of drought stress and mycorrhizal symbiosis on growth and phosphorus (P) uptake by two sorghum cultivars different in root morphology was studied in a pot experiment. A factorial experiment with a randomized complete block design was performed. In this study, sorghum speed feed cultivar with high root proliferation and branching and sorghum KFS2 cultivar with low root proliferation and b...

Abstract Dorema ammoniacum is a medicinal plant, with plenty of chemical constituents, which has been used extensively in curing diseases. To study the salt tolerance of Dorema ammoniacum, its seedlings were put under different salinity treatments under hydroponic conditions. Dorema ammoniacum seeds were transferred to cold (4-5 °C) pretreatment for germination for 27 days. The germinated seed...

In this research, the response of shoot and root of two cultivars of soybean (Glycine max L. cvs Gorgan 3 & Williams) to mild and severe drought was evaluated in pot. Two weeks after of planting, three irrigation treatments including every day (as control), once in three (as mild stress) and five days (as severe stress) were used. The results showed that, stem dry weight, stem and root length, ...

  The aim of the present study was to determine effects of artificial drought stress on the characteristics of germination and seedling growth in bread wheat cultivars. The material of experiment consisted of seeds obtained from eight bread wheat cultivars with different response to drought (Alpu 2001, Sultan 95, Konya 2002, Eser as sensitive cultivars; Karahan 99, Tosunbey, Kate A1 as resista...

Most researches on wheat and barley breeding for salt tolerance have focused mainly on excluding Na+ from different tissues but the results of some experiments suggest that contribution of Na+ exclusion to salt tolerance is overshadowed by other physiological responses. Three bread wheat cultivars differing in salt tolerance (Arg, Tajan and Baharan) and one barley cultivar (Nik) were employed t...
