Open-pit mining activities in the oil sands region of Alberta, Canada, create disturbed lands that, by law, must be reclaimed to a land capability equivalent to that existed before the disturbance. Re-establishment of forest cover will be affected by the production and turnover rate of fine roots. However, the relationship between fine root dynamics and tree growth has not been studied in recla...

Objective: Drought stress is most important factor which reduce root and shoot growth in crops. This study was performed in order to evaluate the effects of drought stress and Zn fertilizer on root traits of four cultivars of chickpea. Methods: Experiment was laid out in a split plot-factorial using randomized complete block design with three replications. Drought stress treatment stand in main...

The investigation was conducted on wet and dry seasons of Ethiopia during the year 2012/2013 at Wondo Genet Agricultural Research Center Nursery site. Four levels of cutting size and three levels of cutting positions were arranged in randomized complete block design with three replications. Data on seedling height, branch number/seedling, root number/seedling, root weigh/seedling, root length/s...

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...

the impact of land use intensity on the abundance and diversity of arbuscular mycorrhizal fungi (amf) was investigated at six land use types viz., natural forest, grassland, acacia plantations, cardamom plantations, coffee plantations and paddy fields in the niligiri biosphere of the western ghats in south india. there was no significant difference in amf root colonization in different land use...

Root architecture is an important regulator of nitrogen (N) acquisition. Existing methods to phenotype the root architecture of cereal crops are generally limited to seedlings or to the outer roots of mature root crowns. The functional integration of root phenes is poorly understood. In this study, intensive phenotyping of mature root crowns of maize was conducted to discover phenes and phene m...

Drought and low water stress is the most important environmental stress which plant are exposed to in low precipitation regions such as southern and central parts of Iran. Milkweed is one of valuable plant species with numerous industrial (producing high quality fibers) and medicinal benefits which has relatively resistance to drought conditions of southern Iran. The present study aimed to inve...

Extended Abstract Introduction: Guar (Cyamopsis tetragonoloba L.) is an annual, dicotyledonous plant of the legume family, also known as cluster beans. This plant can tolerate salinity and drought stress well. Optimal planting date and plant density are factors affecting the quality and quantity of crops. The distribution of plants in the field influences the absorption and productivity of env...

Enlarged root systems that extend into the salt affected soil improve water and nutrient capture by plants and can increase plant productivity. In order to examine root system characteristics of four bread wheat cultivars contrasting in salt tolerance (Arg, Ofoq, Tajan and Morvarid) a greenhouse experiment was conducted with applying two salinity levels (0 and 150 mM NaCl) on plants grown in PV...
