aflp یک ابزار قدرتمند برای تشخیص رونوشت هایی با فراوانی کم است و می تواند بعنوان یک روش کارآمد برای جداسازی ژنهایی که بطور متمایز بیان می شوند، بکار رود. بنابراین القا متمایز ژنها در گندم ( رقم چمران و مرودشت) در پاسخ به قارچ m.graminicola بوسیله آنالیز cdna-aflp مورد مطالعه قرار گرفت . در ابتدا گیاهان بوسیله بیمارگر مایه زنی شدند. نمونه برداری در 6 نقطه زمانی(0، 12، 24، 48، 72 و 96 ساعت) بعد ا...

The effect of dietary protein level and feed restriction on performance, body temperature and hematological values was evaluated, using Ross 308 broiler chicks under heat stress. For this purpose, three dietary treatments were fed to broilers during 21 to 42 days of age. Two treatments consisted of diets with protein levels recommended by NRC, 1994 and 85% of NRC recommendation and were fed ad-...

Nickel (Ni) is an element which has been added recently to the list of necessary micronutrients for plants. But, as a heavy metal, especially at high concentrations, it causes oxidative stress in plants. Knowledge of physiological and biochemical responses of plants to Ni stress can help to understand the mechanisms of adaptability. The effects of Ni on chlorophyll content, proline, soluble pro...

Drought stress as an abiotic stress causes different biochemical and physiological responses in plants. To study changes in chlorophyll, total soluble protein and antioxidant activity due to drought stress, we conducted an experiment on five durum wheat varieties (selected from the Seed and Plant Improvement Institute in Karaj) at research greenhouse of Imam Khomeini International University in...

This experiment was conducted to compare the effect of trimethylglycine supplementation in diets with sufficient or insufficient quantities of protein on blood electrolytes and lipid concentrations in broilers subjected to heat stress condition. Ross 308 broilers were fed with four dietary treatments from 21 to 42 d of age. The treatments consisted of a diet with sufficient levels of protein (...

In order to evaluate on Glutamine Syntetase gene expression as well as amount of protein, chlorophyll and oxidative index of TBARM the experiment has been carried out using Brassica napus (Falcon cv.) in research greenhouse condition. The drought stress treatments were included -0.5, -1, -2, -4 and -6 bar that by using of equivalent water (6.5, 6, 4.7, 3, 1.1 litr respectively) have been irriga...

In order to investigate the genetic diversity and the heritability of oil and protein content of grain in confectionary sunflower under different water availability, 56 local populations were studied in three separate experiments with rectangular lattice design (7×8) with two replications at Agricultural Research Center of West-Azerbaijan province, Urmia, Iran in 2012. Water treatments were wel...
