Heat stress is a major restrictive factor that suppresses rice production. In this study, we investigated the potential priming effect of exogenous abscisic acid (ABA) on heat tolerance in seedlings. Seedlings were pretreated with 10 µM ABA by root-drenched for 24 h and then subjected to conditions 40 °C day/35 night. pretreatment significantly decreased leaf withering 2.5–28.5% chlorophyll los...
The possible effects of seed priming on mitigating the effects of drought stress on germination and early seedling growth of two rangeland plants were evaluated in a laboratory research during 2015-16 growing season. The research was conducted as a 2×3×3 factorial experiment based on completely randomized design with three replications. The first factor was plant type (Festuca ovina and Bromus ...
This study was conducted to study the effects of different priming methods on germination rate and percentage under salinity stress and to determine the stability of primed seeds. In order to accomplish this, three different experiments were conducted separately, including the experiment of water uptake, the experiment of salinity stress, and the experiment of storability of primed seeds. Primi...
The genus AnthemisL. (Asteraceae) as medicinal plants are used both for pharmaceutical purposes and in folk medicine. In order to study of seed priming effects on seedling growth of two species of Anthemis spp., an factorial experiment based on randomized complete design with three replications was conducted under greenhouse conditions in Research Institute of Forests...
Priming tekniği, tohumun ekim öncesinde su veya düşük ozmotik potansiyele sahip çözelti içerisinde belirli bir süre ve sıcaklık altında bekletilerek tekrar kurutulması esasına dayanır. uygulanan tohumlar kurutulduktan sonra direk ekilebilir priming uygulamalarının pragmatik etkilerini kaybetmemek suretiyle sıcaklıklarda uzun depolanabilir. Genel olarak en çok kullanılan teknikleri hidro-priming...
یکی از آلاینده های مهم و سرطان زای موجود در پساب تعدادی از صنایع شیمیایی ارتو تولوییدین است. در این پروژه حذف ارتو تولوییدین با فرایندهای uv/h2o2 و uv/us/h2o2 در واکنشگاه های ناپیوسته چرخشی مورد مطالعه و بررسی قرار گرفته است. در فرایند uv/h2o2 در دمای ثابت 25 درجه سانتی گراد سه عامل مهم شامل غلظت اولیه ارتو تولوییدین، مقدار آب اکسیژنه و ph به عنوان متغیرهای تاثیرگذار بر فرایند مورد بررسی قرار گ...
background: a strong antimicrobial synergism between chlorhexidine (chx) and hydrogen peroxide (h2o2) has been reported, but there is not enough data on the cytotoxicity of this combination. the primary aim of this study was to evaluate the cytotoxicity of chx-h2o2 combination in different concentrations and secondary aim is to assess the infl uence of h2o2 on cytotoxicity of chx on cultured hu...
In order to investigate the effects of seed priming by plant growth regulators( salicylic acid, spermine and spermidine) on some physiological and biochemical characteristics of Okra (Abelmoschus esculentus CV Basenti) under low temperature stress a completely randomized design was conducted at 2014. Experimental treatments include priming of okra seeds with 0.1 mM concentration of Salicylic Ac...
Osmotic stress is the most important of the abiotic stresses that lead to limitation of growth and yield in rapeseed. This study was conducted to examine the effect of cycocel seed priming on osmotic stress tolerance in germination and early growth stages of rapeseed, as a factorial experiment based on completely randomized design at Agriculture College of Shiraz University in 2012. The treatme...
To study the effect of seed priming on seedling emergence characteristics of lentil and evaluate its interaction with drought stress at flowering stage, an experiment was carried out as split plot in a randomized complete block design with three replications at research station of Bu-Ali Sina University, Hamedan, Iran. The main factor consisted drought stress with two levels (conventional irrig...
