background and purpose: according to fao's report, lentil yield in iran is much lower than average yield in the world. this is due to low quality seedling production, low germination and emergence capacity, biotic and abiotic stresses and poor seedling establishment which was forced to looking for a way to enhance these components. seed priming is one of the strategy for increasing the rat...

Despite the importance of arbuscular mycorrhizae to the functioning of terrestrial ecosystems (e.g. nutrient uptake, soil aggregation), and the increasing evidence of global warming, responses of arbuscular mycorrhizal fungi (AMF) to climate warming are poorly understood. In a field experiment using infrared heaters, we found effects of warming on AMF after one growing season in an annual grass...

Introduction: The exact measurement of the root canal length is of great importance in root canal therapy. Although, determination of the root canal length through radiography is the most common method, recently electronic apex locators are being used to determine working length and decrease the number of radiographs. The purpose of this study was to compare the accuracy of an electronic apex l...

This work aimed to evaluate the variability in distribution of root system among genotypes C. canephora cv. Conilon and indicate management strategies for a more efficient mineral fertilization. Root was evaluated six genotypes. The experimental design randomized blocks with three replications. Soil monoliths measuring about 27 cm3 were collected at different soil depths, row distances nine int...

An association mapping panel, named as CIMMYT Asia association mapping (CAAM) panel, involving 396 diverse tropical maize lines were phenotyped for various structural and functional traits of roots under drought and well-watered conditions. The experiment was conducted during Kharif (summer-rainy) season of 2012 and 2013 in root phenotyping facility at CIMMYT-Hyderabad, India. The CAAM panel wa...

Objective. Nd:YAP laser has several potentialities of clinical applications in endodontics. The aim of our study is to determine the safety range of irradiation parameters during endodontic application of Nd:YAP laser that can be used without damaging and overheating the periodontal tissue. Material and Methods. Twenty-seven caries-free single-rooted extracted human teeth were used. Crowns were...

Background & Aim: This experiment investigated the effect of foliar application of methanol and ethanol on the biomass yield of medicinal plant Echinacea purpurea. Purple coneflower is an herbaceous perennial in the Asteraceae family that is used in therapy of respiratory tract infection and bacterial otitis. Experimental: This experiment was conducted in randomized complete ...
