to determine the effect of zn and mn enriched seed on quality of two winter safflower varieties under drought stress, an experiment was conducted at the agricultural faculty research field, tarbiat modarres university, during 2004-2005 cropping season. the design was a split factorial randomized complete block one of 3 replications. main plots were composed of 3 different levels of drought stre...
Tobacco is a salt-sensitive glycophyte crop species. In this work effect of silicone (Si) supplementation (1 mM as Na2SiO3) was studied in Nicotiana rustica L. cv. Basmas grown hydroponically in growth chamber under control, low (25 mM) and high (75 mM) NaCl concentration for two weeks. Dry matter production of leaves was depressed by salinity level as low as 25 mM and higher salt concentration...
this ethnographic case study research was carried out in a private school setting in the context of iran. the research tried to explore the analysis and identity construction of a group of learners and teachers along with the content analysis of books on the basis of four types of commodified, political, national and narrative identities. how english language learners and teachers in an informa...
To evaluate the physiological responses of chrysanthemum to silicon spray in non-stress conditions, this study was performed in two separate experiments (at 4 to 5 and 8 to 12-leaf stages) as a factorial randomized completely design with two factors: silicon source (in two levels: sodium silicate and calcium silicate) and the concentration of silicate at five levels (0, 50, 100, 150 and 200 mg ...
The rice crop is cold sensitive plant that under cold stress is more decreasing yield. Therefore, knowing defense mechanism of rice crop and low temperature is necessary. In order to, the effects of cold on some morphological and physiological characters of two rice (Oryza sativa L.) varieties (Onda and Domsiah) were studied under control treatment (day/night 28o/25o) and were treated after two...
This research was performed to compare Pb and Cd accumulation in root and leaves of pinus brutia. The effects of these elements in different concentrations (0, 200, 500 and 1000) on the amount of proline, soluble sugar of the plant were also investigated. The experiment was done in a factorial design in three replicates. The concentration of Pb and Cd in leaves and root were measured by atomic ...
abstract this study evaluates the iranian pre-university english textbook in terms of needs, objectives, content, and methodology. the study was designed on the qualitative- quantitative survey basis using interviews and questionnaires, a researcher-made textbook evaluation checklist and a needs analysis questionnaire. the textbook evaluation questionnaire was used in this study to elicit the ...
The work was carried out to investigate the effects of different concentrations of NaCl on Brachiaria humidicola Rendle in the presence and absence of Glomus etunicatum Becker and Gerdemann, as well as to evaluate some growth parameters and the accumulation of free proline in the plant leaves. The soil used was a Neosoil Fluvic Eutrophic with pH of 6.5, organic matter, 12.8 g kg-1 and soil text...
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...
Sandal (Santalum album L) contains several interesting amino acids and amines which are not seen in other plants. This includes cis-4-hydroxy-l-proline in free form in leaves, flowers and seeds while trans-4-hydroxy-l-proline in bound form. Traces of 3, 4 dehydroproline is also detected in sandal leaves. Biosynthesis of cis-4-hydroxy proline indicates that hydroxylation taken place at proline p...
