Herbicides control annual winter weeds in bermudagrass turf
Weeds are commonly found in bermudagrass turf during the winter and early spring throughout the Southeastern United States whether this turf is used for lawns, parks, athletic fields or golf courses. Mild winter temperatures favor rapid growth of these annuals. When bermudagrass goes dormant in the fall after the first killing frost, it does not compete with germinating winter weeds. Bermudagra...
متن کاملRelative salt tolerance of south Khorasan millets
Abstract Millets are important agricultural crops for arid regions due to short life span and their resistance to salinity and drought conditions. In Iran, three main species of millets including proso millet (Panicum miliaceum), foxtail millet (Setaria italica) and pearl millet (Pennisetum glaucum) are cultivated in Shouthern Khorasan province, eastern Iran. In order to assess inter-specific...
متن کاملEvaluation of freezing tolerance in olive cultivars by stomatal density and freezing stress
Selection of frost tolerant cultivars and understanding the mechanisms of frost hardiness could help to improve freezing resistance in olive plants. Olive cultivars may differ in frost hardiness due to differential survival of specific organs. The aim of this study was to screen different olive cultivars based on their stomatal density and metabolic modifications under cold conditions. The ‘Zar...
متن کاملFreezing Tolerance of Chickpea Genotypes in Controlled Conditions
Lack of chickpea cultivars tolerant to extreme freezing is a limiting factor for autumn planting of this crop in cold areas. In this study, 58 Kabuli-type chickpea genotypes and a control (an international sensitive genotype) were planted in pots and first exposed to -10°C and then to -15°C after being acclimated in natural conditions. No destructive effect of -10°C was observed in plants. So, ...
متن کاملGenomic Regions Associated with Tolerance to Freezing Stress and Snow Mold in Winter Wheat
Plants grown through the winter are subject to selective pressures that vary with each year's unique conditions, necessitating tolerance of numerous abiotic and biotic stress factors. The objective of this study was to identify molecular markers in winter wheat (Triticum aestivum L.) associated with tolerance of two of these stresses, freezing temperatures and snow mold-a fungal disease complex...
