A Strategy for Deficit Control Through Faster Growth
The February 1994 federal budget stated the government’s intention to achieve a budgetary deficit that will not exceed 3 per cent of GDP in the fiscal year 1996-971. It also announced a number of tax and spending measures as first steps towards that goal. But these were clearly insufficient for the target to be met on schedule. Table 1 presents the government’s most recent grey book projections...
متن کاملGrowth of Arabidopsis thaliana seedlings under water deficit studied by control of water potential in nutrient-agar media.
We have characterized the growth responses of Arabidopsis thaliana seedlings to water deficit. To manipulate the water potential, we developed a method whereby the nutrient-agar medium could be supplemented with polyethylene glycol (PEG 8000); PEG was introduced into gelled media by diffusion, which produced media with water potential as low as -1.6 MPa. For dark-grown plants, hypocotyl growth ...
متن کاملGenetic and physiological controls of growth under water deficit.
The sensitivity of expansive growth to water deficit has a large genetic variability, which is higher than that of photosynthesis. It is observed in several species, with some genotypes stopping growth in a relatively wet soil, whereas others continue growing until the lower limit of soil-available water. The responses of growth to soil water deficit and evaporative demand share an appreciable ...
متن کاملRegulation of Root Growth Responses to Water Deficit
The growth and function of roots are essential for crop productivity under waterlimiting conditions, but direct improvement of roots by plant breeding has been slow. One difficulty is the observation and quantitative measurement of root systems under conditions that are relevant to field environments. Another challenge is the identification of and selection for specific loci that could improve ...
متن کاملEffects of Superabsorbents on Growth and Physiological Responses of Date Palm Seedling under Water Deficit Conditions
Irrigation is an inevitable part of agriculture which determines crop yield and thus food security. In modern era of agriculture, crop yield is determined on the basis of crop production per unit of water-use instead of crop production per land unit area. Deficit irrigation is introduced as a strategy for controlling water resources that leads to water resource preservation. Date palm requires...
