Inhibitory effects of water deficit on maize leaf elongation.
The growth rate of maize leaves has been investigated for plants grown in pots in controlled conditions and subjected to slow drying over a period of days. The elongation of leaves experiencing water deficit was inhibited primaily during the afternoon. No decrease in the turgor of the growing cells could be detected at that time. Solute concentration in the growing cells increased in tissue exp...
متن کاملResponse of different species of Brassica to water deficit
Development of drought-tolerant cultivars is hampered by a lack of effective selectioncriteria. In this research, response of 36 genotypes of rapeseed from seven species of Brassicaincluding B. napus, B. rapa, B. juncea, B. carinata, B. oleracea, B. nigra and B. fruticulosa wasassessed under three moisture levels (no stress, mild stress and intense stress) in the field during2011-2012. Five dro...
متن کاملDeficit irrigation for reducing agricultural water use.
At present and more so in the future, irrigated agriculture will take place under water scarcity. Insufficient water supply for irrigation will be the norm rather than the exception, and irrigation management will shift from emphasizing production per unit area towards maximizing the production per unit of water consumed, the water productivity. To cope with scarce supplies, deficit irrigation,...
متن کاملResponses to Water Deficit'
Water deficit elicits a complex of responses beginning with stress perception, which initiates a signal transduction pathway(s) and is manifested in changes at the cellular, physiological, and developmental levels. The set of responses observed depends upon severity and duration of the stress, plant genotype, developmental stage, and environmental factors providing the stress. Cellular water de...
متن کاملP129: Use of Stem Cells to Regenerate Degenerative Optic Nerve
Stem cells are undifferentiated cells that have the ability to convert to different types of cells and after dividing, they can produce their own cells or other cells. Axons of the retinal ganglion cells, from the optic nerve. These cells lose the ability to regenerate themselves before birth. Optic nerve degeneration can result from various causes including increased intraocular pressure, comp...
