Plants have evolved effective mechanisms to avoid or reduce the potential damage caused by abiotic stresses. In addition to biocontrol abilities, Trichoderma genus fungi promote growth and alleviate the adverse effects caused by saline stress in plants. Morphological, physiological, and molecular changes were analyzed in salt-stressed tomato plants grown under greenhouse conditions in order to ...
Chemical mutagenesis is an efficient tool used in mutation-breeding programs to improve the vital characters of the floricultural crops. This study aimed to estimate the effects of different concentrations of two chemical mutagens; sodium azide (SA) and diethyl sulfate (DES). The vegetative growth and flowering characteristics in two generations (M1 and M2) of calendula plants were investigated...
Drought as the most important problem of agricultural development in Iran is one of the main obstacles in the production of agricultural products. Because the global approach to the production of medicinal plants is effective in improving the quantity and quality of the substance, today the use of salicylic acid as one of the plant hormones in increasing plant resistance to stresses such as dro...
abstract objectives gradual increase length and complexity of utterance (gilcu) therapy method is a form of operant conditioning. this type of treatment is very precise and controlled that is done in 54 steps in 3 speech situations consisted of monologue, reading and conversation. this study aimed to examine the effects of gilcu treatment method on reduction of speech dysfluency of school-age...
effect of seed priming on germination and seedling growth of sesame investigated under controlled conditions. the primed seeds with znso4 had the maximum germination percentage whereas the highest germination rate was observed in hydro-primed seeds. the treated seeds with peg showed the best growth of the seedlings and rootlet. the complementary field experiment was conducted to evaluate the ef...
The non-protein amino acid β-aminobutyric acid (BABA) can induce plant resistance to a broad spectrum of biotic and abiotic stresses. However, BABA-induced plant resistance to insects is less well-studied, especially its underlying mechanism. In this research, we applied BABA to wheat seedlings and tested its effects on Sitobion avenae (F.). When applied as a soil drench, BABA significantly red...
We functionally characterized the grape (Vitis vinifera) VvPIP2;4N (for Plasma membrane Intrinsic Protein) aquaporin gene. Expression of VvPIP2;4N in Xenopus laevis oocytes increased their swelling rate 54-fold. Northern blot and quantitative reverse transcription-polymerase chain reaction analyses showed that VvPIP2;4N is the most expressed PIP2 gene in root. In situ hybridization confirmed ro...
This study was designed to isolate and characterize Azospirillum strains from maize (Zea mays L.) grown under wellwatered and water stressed conditions and to evaluate the ability of bacteria to produce plant growth promoting hormones like Indole Acetic Acid (IAA), Gibberellic Acid (GA), trans-Zeatin riboside (tzr) and abscisic acid (ABA). A total of eight strains of Azospirillum were isolated ...
Due to recent droughts in Iran and other parts of the world and consequently limited water resources, tending to aquaponic system, in which fish and plants grow together, is a logical and practical method. For this reason, in the current experiment, possibility of mint planting in aquaponic system and the effects of applying nano-fertile fertilizer containing 60% humic acid on its growth was in...
