the west of esfahan province, iran, is one of the most important agricultural areas throughout the country due to the climate variability and life-giving water of zayanderood river. rice is one of the major and economic crops in this area. the most important climatic elements in agricultural activities which should be considered include temperature, relative humidity, precipitation and wind. so...
safflower is one of the oldest cultivated plants and oilseed as a native iran could have in the development of oilseeds cultivation. to evaluate the morphological characteristics of safflower (carthamus tinctorius l) an experiment was conducted as a completely randomized design. the figures include 1- pi 23755 2-pi 239041 3- pi 250202 4- pi 250532 5- pi 25268 6- pi 253515 7- pi 253541 8- pi 253...
Drought stress influences seed germination and seedling growth of many plants. Seed coating is technique of covering seeds with adhesive agents to improve seed performance and plant establishment and could be used to alleviate the negative effects of osmotic stress. In order to solve the problem of low germination and poor vigor of sweet corn under osmotic stress conditions (0, -0.3, -0.6 and -...
Ferula ovina is one of forage species of Isfahan and Chaharmahal va Bakhtiari whose natural spreads are under destruction. Finding information about its seed dormancy, effective factors in the dormancy breaking and also about optimal conditions of seed germination is necessary for recovery of this plant spreads. To actieve that goal, two factorial experiments were performed in completely random...
seeds of most crops including those of range plants follow orthodox behavior. however, these seeds undergo aging even under favorable conditions, so that decreased viability and vigor related parameters are the main characteristics of deteriorated seeds. the effects of hormonal priming with auxin, cytokinin, gibberellin and abscisic acid at 0, 50, 100 and 150 ppm on physiological quality of tal...
DOR: 98.1000/2383-1251.1398.6.33.11.1.1575.41 Extended Abstract Introduction: In addition to dormancy, seeds of Allium hirtifolium have a weak emergence in the field. Among methods for improving the efficiency and emergence of seeds, nutritional priming can be considered for its performance on weak seeds. The presence of micronutrients is one of the factors that may affect the efficiency ...
dynamic assessment according to vygotskys sociocultural theory, states that instruction and assessment are interrelated. using static forms of assessment with second and foreign language students could do more harm than good. many teachers neglect to take account of the complexity involved in learning a second or foreign language and often wonder why learning of a language take so long. thi...

We quantified and characterized the expression of heat-resistant proteins during seed development of maize lines with distinct levels of tolerance to high drying temperature. A corn field was planted for multiplication of seeds of different lines, two tolerant and two non-tolerant to high drying temperatures. Harvest of the seeds was carried out at various stages of development and they were th...
DOR: 98.1000/2383-1251.1398.6. 19.11.1. 1603.1606 Extended Abstract Introduction: Guar (Cyamopsis tetragonolob) which belongs to fabaceae and leguminosae families is self-pollinating and is indigenous to India and Pakistan. This plant is suitable for growth in dry, damp and sandy soils, and can tolerate saline and relatively alkaline soils. Determining the best time for harvesting seeds and...
