to better understand seed dormancy breaking of bread wheat (triticum aestivum l.rl4137), we examined protein synthesis in dormant and after-ripened seeds.we used six treatments including dormant seed, dormant seed that were subjected to gibberllic acid (ga3) for 10 hours, dormant seed with one, three and six weeks of after-ripening and finally six weeks after-ripened seed subjected to abscisc a...
Switchgrass is a perennial C4 plant with great potential as a bioenergy source and, thus, a high demand for establishment from seed. This research investigated the effects of ultrasound treatment on germination and seedling growth in switchgrass. Using an orthogonal matrix design, conditions for the ultrasound pretreatment in switchgrass seed, including sonication time (factor A), sonication te...
Background[d1] and Objective: Cancer is a prevalent disease that occurs due to genetic and environmental factors. Gastric cancer is one of the most common cancers around the world and also in Iran. N. sativa has been used as a drug in the treatment of many diseases owing to its valuable secondary metabolites such as thymoquinone. In this study, the anti-cancer properties of black seed extract...
DOR: 98.1000/2383-1251.1398.6.77.11.1. 1575.1605 Extended Abstract Introduction: Iran is located in the arid and semi-arid regions of the world with an average rainfall of 240 mm per year, which requires rethinking of the adoption of methods. One of the alternative ways is to use organic and biological fertilizers. Biological fertilizers are considered as the main and the most important f...
Strong seed dormancy has been an obstacle for field production of Echinacea species. Previous research on overcoming Echinacea seed dormancy has been extensive and focused on treatment methods, which involve time and expense, and are incompatible with organic production if synthetic chemicals are used. We have attempted to genetically reduce seed dormancy through selection and breeding in Echin...
BACKGROUND: Fertilizer management plays an important role for obtaining satisfactory yields and to increase crop productivity. Nutrient management may be achieved by the involvement of organic sources, bio fertilizers, and micro-nutrients. OBJECTIVES: Assessment effect of chemical and biological fertilizer on seed yield, its components and plant height of...
the purpose of this study was to examine the comparative effect of story retelling and role playing on efl learners’ vocabulary learning and reading comprehension. to carry out the purpose of the study 90 female learners of tabarestan language school located in noshahr were non-randomly selected. they took pet test and among these 90 participants 62 students were selected as homogenous learners...
Seed priming is the most important technique for increasing the germination power. This study was conducted to investigate the effects of halopriming and hydropriming on improvement of seed germination in black locust (Robinia pseudoacacia L.) in a completely randomized design with 4 replications. Halopriming treatments of KNO3 with concentrations including (100, 250, 500, 750 mM) and hydropr...
Objective: In this study investigated effects of different amounts of pelleted manure with urea and micro elements on yield and seed quality of medicinal plants, pumpkin (Cucurbita pepo var. styriaca). Methods: The animal manure and urea as pellet with four levels (150 Kg urea, 50 Kg urea + 3.5 ton animal manure, 100 (Kg) urea+ 1.5 ton animal manure and 150 (Kg) urea+1.5 ton animal man...
