this study was designed to investigate the impacts of teachers self-disclosure on students foreign language classroom anxiety, attitude to english language learning and their achievement scores at the end of the term. there were 48 female learners of intermediate level. they were not randomly selected. there were one experimental group with 21 students and one control group with 27 students.the...
DNA methylation has been referred as an important player in plant genomic responses to environmental stresses but correlations between the methylome plasticity and specific traits of interest are still far from being understood. In this study, we inspected global DNA methylation levels in salt tolerant and sensitive rice varieties upon salt stress imposition. Global DNA methylation was quantifi...
this thesis aims at putting together two of the vestest areas of study there is in humanities: bioethics and literature. the two novels in question, oryx and crake and the year of the flood, are considered as some of the most succssful examples of spculative fiction. in these novels the biological and environmental issues raised as looked at from a bioethics point of view.
This research was carried out in order to evolution effect of salt stress on seedling growth and antioxidant activity of two safflower cultivars KW13 and IL111 in Islamic Azad University, Shoushtar branch. Salt stress treatments were applied using salt solutions with EC values of 0 (control), 4,6, 8,10 and 12 ds/m. All experiments were carried out under a dual factorial (cultivar × salinity lev...
salinity is among important soil stresses adversely affecting the process of nitrogen (n) fixation in leguminous plants in different parts of the world. it has been indicated that salinity can inhibit the early stages of nodulation process between bacterium and the host plant including the exchange of signal molecules (nod gene inducers). there has not been any research regarding the effects of...
Flowering is a crucial developmental stage in the plant life cycle. A number of different factors, from environmental to chemical, can trigger flowering. In pineapple, and other bromeliads, it has been proposed that flowering is triggered by a small burst of ethylene production in the meristem in response to environmental cues. A 1-amino-cyclopropane-1-carboxylate synthase (ACC synthase) gene h...
Soil and water salinity substantially constrain crop and biomass production. To investigate the changes in morphological parameters of lisianthus (Eustoma grandiflorum) cultivars under CaCl2 salinity conditions a greenhouse experiment was conducted. Cultivars namely, ‘Champagne’ (C1), ‘Lime Green’ (C2), ‘Blue Picotee’ (C3) and ‘Pure White’ (C4), were subjected to salt stress (0–30 mM CaCl2) in ...
Reactive oxygen species (ROS) release from cellular water molecules under abiotic and biotic stresses which are harmful for cellular metabolism. Although, some of radical injuries neutralize via plant enzymatic and nonenzymatic reactions like antioxidant system such as superoxide dismutase, catalase, peroxidase and ascorbate peroxidase. Aeluropus littoralis Parl. is a halophyte plant belongs...
An experiment was conducted to determine the responses of 27 Iranian local and improved rice genotypes to two salinity levels (0 and 100 Mm NaCl) at Soilless Culture Research Center of Isfahan University of Technology. The treatments were arranged as factorial in a completely randomized design with three replications. The results showed that there was considerable variation in agro-morphologica...
