in order to evaluate the effect of zeolite application and selenium spraying on some physiological traits and grain yield in medicinal pumpkin (cucurbita pepo l.) under different moisture regimes, a study was conducted in a factorial experiment based on randomized complete block design with three replications during 2010 in takestan at gazvin province, iran. the three levels of irrigation facto...

this experiment was conducted in order to evaluate the effects of foliar application of ordinary and nano-particles of zinc oxide on the response of corn to salinity. treatments included two corn genotypes (seed mass and sc 704), three spray levels (zinc oxide, nano-sized zinc oxide, and a spray of water treatment) and three salinity levels (0, 75 and 150 mm nacl). shoot dry matter was decrease...

It is now widely accepted that calcium (Ca) deficiency is linked to potato (Solanum tuberosum L.) tuber disorders and improved tuber health is expected through increased Ca availability. The purpose of this study was to optimize the Ca concentration in Murashige-Skoog (MS) basal medium for microtuber production and determine microtuber mineral composition, especially Ca content. The response of...

in this study, the effect of drought stress on morphological and physiological characteristics of wheatgrass and tall fescue was investigated in a factorial-split plot in time arrangement based on a completely randomized design with three replications. after turf establishment, half pots were exposed to drought stress and the half other were completely irrigated. based on the results tall fescu...

in order to investigate the effect of cycocel on different growth aspects of two olive cultivars (mary and mission), a greenhouse experiment was conducted taking into account three factors of: cycocel at three levels (0, 500 and 1000 mg l-1), drought stress of three levels (irrigated at 5, 10 and 15 days intervals) and two olive cultivars (mary and mission) in a factorial experiment based on ra...

Less than 5% of the total pool of free amino acids in plants under stress-free conditions is provided by proline. In many plants under various forms of stress, the concentration increases up to 80% of the amino acid pool. This observation raises the question about the molecular mechanisms, making a high proline concentration favourable under stress conditions. Therefore, the literature about th...

Nanoparticles are atomic or molecular particles with at least 1–100 nanometer diameters. They have entered vastly into the world of agriculture and biology; this is because of their special effect and their unique features. Their unknown impact on living things and the ecosystems has caused a lot of concern. This research was done in order to study the effects of nano-TiO2 and nano aluminium on...

Background and Aims Viticulture will be particularly affected by increasing drought heat waves in the future. It is of interest to find traits that indicate stress before symptoms become apparent. We investigated whether commonly used traits, proline abscisic acid (ABA) biosynthesis, are suitable markers for heat, or combined gene expression key enzymes ABA biosynthesis regulated grapevine leav...

in order to study the effects of pgpr application methods on proline and soluble sugars content of yarrow (achillea millefolium l.) under drought stress conditions an experiment was performed at islamic azad university, yadegar-e-imam khomeini (rah) shahre-rey branch. this experiment was carried out in a split plot arrangement with randomized complete block design in three replications. experim...
