In the turfgrass industry, the need for salinity tolerant turfgrasses is increasing because of the increased use of saline and non-potable water. Greenhouse container experiments were conducted to determine the relative salinity tolerance and growth responses of eleven native populations of tall fescue (Festuca arundinacea Schrub) (TF), including: Semirom, Mashhad, Sanandaj, Yasuj, Yazd Abad, D...
In order to study the effect of zinc (Zn) nutrition on relative tolerance of olive (Olea europea L.) seedlings to salinity, a factorial pot experiment was conducted, based on completely randomized design with three replications, during fall 2013. One-year seedlings of two olive cultivars (‘Frontoio’ and ‘Conservolea’) were planted in 10-litre plastic pots containing sand and perlite (1:1 ratio)...
In order to examine the impact of different levels of salinity on yield and germination of 40 cultivars and local populations of cotton in greenhouse and field experiments were conducted at Rodasht Agricultural Research Station - Isfahan. In greenhouse experiments using a completely randomized design with three replications, effect of water with a salinity of 9 dS m-1 on germination rate and pe...
This study was conducted at Biology Department, Faculty of Science,Taif University, Saudi Arabia to investigate the effect of different salinity concentrations 8.6, 12.9, 17.2, 25.9, 34.5, 51.7, 86.2, 103.4 and 120.7 mM NaCl, beside control treatment (tap water) on growth parameters, leaf measurements and leaf chemical constituents of jojoba (Simmondsiachinensis (Link) Schneider). The results i...
اثرات اسید سالیسیلیک بر برخی از ویژگیهای مورفو-فیزیولوژیکی و بیوشیمیایی دانهال گردو تحت تنش شوری
Salinity of water irrigation and soil are of the major factors affecting plant growth and productivity worldwide. In this research the effects of salicylic acid on some morpho-physiological and biochemical characteristics of walnut (Juglans regia) seedlings under salinity stress condition were studied. The experiment was a two-factor factorial experiment arranged in completely randomized design...
crops growing in salt-affected soils may suffer from physiological drought stress, ion toxicity, and mineral deficiency. a pot study was conducted in 2004-2005 in the aghala area (northern iran) to study the effect of different salinity levels, i.e. ece= 3 (control), 8, 12 and 16 ds m-1 on wheat grain, yield components and leaf ion uptake of four iranian wheat genotypes, i.e. kouhdasht, atrak, ...
Low quality of irrigation water along with increasing salinity level has reduced the olive yield over recent years in Iran. Screening of salinity tolerance in olive cultivars using gas-exchange parameters, water use efficiency, and relative leaf chlorophyll content are important in olive development programs. This study was carried out to assess the salinity tolerance of four olive cultivars (A...
to study the interaction effect of the salinity and salicylic acid on some morphological and physiological traits in clary sage (salvia sclarea), a pot experiment was conducted as factorial based on a completely randomized design with three levels of nacl and control (zero, 50, 100 and 150 mm), as the first factor and three levels of spraying the solution of salicylic acid and control (zero, 10...
the purpose of this study is to investigate the relationships between teachers’ immediacy behaviors and iranian students’ willingness to talk in english classes. analysis of the results from willingness to talk scale represents a relatively high level of willingness to talk in english classrooms among iranian language learners. the total mean score of students’ willingness to talk was 66.3 ou...
Leaf area is a key indicator for the growth and production of plant products and also determines the efficiency of light consumption. Therefore, the study of diversity and also the estimation of leaf area in different mint ecotypes is particular importance. One of the common methods for estimating leaf area is regression analysis, the leaf area as independent variable, and leaf length and ...
