Thymus with more than 200 species is known for its medicinal and culinary uses. There is an increasing demand for thyme and its products, requiring cultivation under different conditions, including drought. To understand the response of thyme to water deficit and its variation across the genus, eleven populations from a range of species (Thymus daenensis, T. kotchyanous, T. vulgaris, T. serpyll...

Research pertaining to genetic variability parameters, heritability, and genotypic, phenotypic, simple, and environmental correlations for various seedling traits in five elite advanced cotton (Gossypium hirsutum L.) lines (FH-113, FH-114, FH-941, FH-942, and FH-2015) and one check (CIM-496) was carried out during October and November 2010 under greenhouse conditions at the Cotton Research Inst...

Drought stress is the major problem in arid and semi-arid regions of the world. Investigating the response of different cultivars of crop plants to drought stress can help to select the tolerant ones for agriculture in arid lands. In this study, a greenhouse experiment was conducted as a factorial experiment based on completely randomized design with two common bean cultivars (Phaseolus vulgari...

Effects of water stress and Fusarium oxysporum f. sp. lycoperseci (Fol) on the growth of tomatoes were studied in a greenhouse experiment. Treatments consisted of five levels of water stress (1, 3, 5, 7 and 9 day irrigation intervals). Infested soil consisting of 400 chlamydospores g1 of Fol and non infested soil were used. Experiments arranged in a completely randomized design with 8 replicati...

in this study the response of 9 rapeseed genotypes were evaluated at the seedling stage using different irrigation levels (50, 70 and 100% fc). a factorial experiment based on rcbd was conducted in the research greenhouses of urmia university with four replications during summer of 2013. some physiological traits such as relative water content, stomatal conductance, transpiration, photosynthesi...

this study investigated intra-specific variation in the growth parameters and dry mat-ter partitioning of sugar beet cultivars at different levels of salinity (0, 50, 150, 250 and 350 mm nacl + cacl2 in 5:1 molar ratio) using four cvs, one british (madison) and three iranian cvs (7233-p12, 7233-p21 and 7233-p29). the plants were grown in a controlled greenhouse environment for about 18 weeks. a...

salinity is one of the most important limiting factors for crops, because of most agronomic and horticultural crops are sensitive to salinity. on the other hands, considerable lands of the world were affected by salinity and they are increasing day by day. an experiment was conducted with five levels of irrigation water salinity in soilless culture and greenhouse condition to evaluate the effec...
