turf is one of the most important ground covers and it is one of the main elements ofurban landscape design. plant growth regulators, such as growth inhibitors, are widelyused in turfgrass management to suppress shoot growth and inflorescences production.this experiment was conducted to determine the interactive effects of trinexapac-ethyl(te) and salinity on the growth, visual quality, and che...

In this study the effects of drought stress on proline, protein, chlorophyll a/b, ascorbate and dehrydroascorbate were investigated in Akri and Mobil cultivars of tomato species. The seeds were cultured at 23 °C with 15-16 hours light period and irrigation was done based on field capacity control (FC), mild drought stress (⅔ FC) and severe drought stress (⅓ FC) under greenhouse conditions. Afte...

application of nanofertilizers is one of the promising methods for increasing resources use efficiency and reducing environmental pollutions. uncontrolled application of chemical fertilizer and pesticides has caused many problems to human health and domestic animals. nanofertilizers application could be a suitable way to reduce these problems. accordingly, in order to assess the silicon nanopar...

two field experiments were conducted at the research farm of the faculty of agriculture, university of tabriz, iran during 2009-2010 and 2010-2011, to evaluate the response of fennel (foeniculum vulgare l.) landraces to limited irrigation. experiments were arranged as split plot based on randomized complete block design in three replications with irrigation treatments (irrigation after 60, 90, ...

cold stress is considered as a restricting factor in plant production. recently, many different compounds were applied to minimize the harmful effects of stress. in this study, the effects of foliar application of salicylic acid was studied on some biochemical properties of two different cold resistant canola cultivars. salicylic acid was sprayed at four concentrations (0, 100, 200 and 400 µm) ...

abstract background and objectives: soil salinity is one of the most important limited factors of plant productions. physiological drought resulting from salinity stress is one of the main reasons of limiting water absorption from soil. moreover, increasing the salt absorption by plants cause to disorder in physiological and cellular processes. spearmint (mentha spicata l.) is from lamiaceae fa...

silicon is known to ameliorate the deleterious effects of drought on plant growth. we evaluated growth of wheat (triticum aestivum l. cv. chamran) under water-deficit stress induced by polyethylene glycol as affected by si application. in this article, the effects of si (as potassium silicate) on some parameters related to growth, chlorophyll concentration relative water content (rwc), electrol...

salinity is one of the major problems in the world's vast areas of land are also faced with this problem. endophytes are microorganisms that use of the soil microorganisms, the reduction of environmental stresses such as salinity, has become a global solution. therefore, to investigate the effects of inoculation of fungal endophytes piriformospora indica and bacteria symbiosis hay azospiri...

in order to study the effects of foliar application of zn and k on yield and some physiological traits of spring safflower (carthamus tinctorius l.), cv. esfahan 14, under drought stress, a pot experiment was conducted in research greenhouse of yasouj university. experiment was a factorial based on completely randomized design with three replications. factors consisted of drought stress (s1- wi...
