evaluation of irrigation water management and boron fertilizer to increase water use efficiency of sugar beet
this study evaluated the irrigation water management and different amounts of boron fertilizer affacts on yield and and water use efficiency of sugar beet. the two-factor factorial design in randomized complete block with three replications of irrigation and different levels of boron fertilizer for three years (2000-02) was designed in qazvin. the main four irrigation treatments were t1, t2, t3...
متن کاملCarbon Assimilation and Leaf Water Status in Sugar Beet Leaves during a Simulated Natural Light Regimen.
Carbon assimilation and leaf water status were studied in sugar beet (Beta vulgaris L., Klein E-type multigerm) leaves during a light period in which illumination either increased rapidly to full irradiance or changed gradually in a sinusoidal manner as generally occurs during a natural day. A light regimen that simulated the light of a natural day was produced by adjusting irradiance with a ne...
متن کاملEffect of defoliation on leaf physiology of sugar beet cultivars subjected to water stress and re-watering
Water stress causes defoliation, which can reduce yield and root quality of sugar beets (Beta vulgaris L.) through altered gas exchange characteristics of the leaves. In a two-year experiment, three sugar beet cultivars (Europa, Rival and Corsica) were subjected to three defoliation levels (control-C, moderate-MD, severe-SD) and re-watering after their exposition to drought for a month. Leaf ph...
متن کاملCorrection: Plant Water Use Efficiency over Geological Time—Evolution of Leaf Stomata Configurations Affecting Plant Gas Exchange
Plant gas exchange is a key process shaping global hydrological and carbon cycles and is often characterized by plant water use efficiency (WUE - the ratio of CO2 gain to water vapor loss). Plant fossil record suggests that plant adaptation to changing atmospheric CO2 involved correlated evolution of stomata density (d) and size (s), and related maximal aperture, amax . We interpreted the fossi...
متن کاملTopical Review on Stomata and Water Use Efficiency Stomatal Size, Speed, and Responsiveness Impact on Photosynthesis and Water Use Efficiency
The control of gaseous exchange between the leaf and bulk atmosphere by stomata governs CO2 uptake for photosynthesis and transpiration, determining plant productivity and water use efficiency. The balance between these two processes depends on stomatal responses to environmental and internal cues and the synchrony of stomatal behavior relative to mesophyll demands for CO2. Here we examine the ...
