in order to investigation of waterlogging stress effects on morphological and physiological traits of rapeseed in different developmental stages, a pot experiment was conducted at gorgan university of agricultural sciences and natural resources during 2010-2011. the experiment design was completely randomized with factorial arrangement and three replications. examined factors were developmental...

A plant-based system for continuous production of monoclonal antibodies based on the secretion of immunoglobulin complexes from plant roots into a hydroponic medium (rhizosecretion) was engineered to produce high levels of single-chain and full-size immunoglobulins. Replacing the original signal peptides of monoclonal antibodies with a plant-derived calreticulin signal increased the levels of a...

Development of vegetative and floral buds was found to be a key factor in establishing the way carbon is distributed among growing leaves and fruits in Phaseolus vulgaris L. plants. Leaves emerged principally during a period 14 to 32 days after planting while flowers were produced during a 10- to 12-day period near the end of leaf emergence. Timing of anthesis established the sigmoidal time cou...

The effects of pre-sowing magnetic treatments on the growth and yield of tomatoes (cv. Vyta), cultivated late in the season, were studied under field conditions. Tomato seeds were exposed either to a 120 mT dynamic magnetic field (induced by an experimental electromagnet) for 10 min or to a 80 mT field for 5 min. Non-treated seeds were used as controls. Plants were grown in experimental plots (...

The aim of this study was to investigate the effects of a medical plant mixture and a probiotic on performance, antioxidant activity and weaning age of suckling Holstein calves. For this experiment, 30 newborn calves (0-10 days of age) with an average birth weight of 42 ± 8 kg were used in a factorial design (3×2) with 6 treatments and 5 replicates. Treatments were: 1) basal diet including a ca...

Two field experiments were carried out during the winter seasons of 2000/2001 and 2001/2002 at the Agricultural Experimental Station (at Abeis) Alexandria University, to investigate the response of globe artichoke plants cv. French, to the inoculation with Halex2 and Microbein biofertilizers under varying N levels (0, 45, 90 and 135 kg N fed -1 ). The results indicated that increasing N applied...

drought, high and low tempratures are the most important abiotic stresses in chickpea cultivation. improving plant root characteristics (root length and root volume) is one of the ways to increase drought tolerance in chickpea. mycorrhizal symbiosis increases drought resistance of host plants through different mechanisms. to study the effects of water stress and mycorrhizal fungi inoculation on...
