Regulation 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 کاملDynamic modeling of root water uptake using soil moisture data
In this work a dynamic model of water uptake from plants growing in naturally vegetated areas subjected to a rainfall and evaporation time series is described. The model results are compared and contrasted with popular pre-existing models. Also, the effects of the uptake pattern on the movement of water across multiple soil layers are also analyzed. The results showed that contrary to common mo...
متن کاملA Soil-Plate Based Pipeline for Assessing Cereal Root Growth in Response to Polyethylene Glycol (PEG)-Induced Water Deficit Stress
Drought is a serious problem that causes losses in crop-yield every year, but the mechanisms underlying how roots respond to water deficit are difficult to study under controlled conditions. Methods for assaying root elongation and architecture, especially for seedlings, are commonly achieved on artificial media, such as agar, moistened filter paper, or in hydroponic systems. However, it has be...
متن کاملRoot Growth and Water Uptake by Maize Plants in Drying Soil
Sharp, R. E and Da vies, W. J. 1985. Root growth and water uptake by maize plants in drying soil.— J. exp. Bot. 36: 1441-1456. The influence of soil drying on maize (Zea mays L.) root distribution and use of soil water was examined using plants growing in the greenhouse in soil columns. The roots of plants which were watered well throughout the 18 d experimental period penetrated the soil profi...
متن کاملRoot water potential integrates discrete soil physical properties to influence ABA signalling during partial rootzone drying.
To investigate the influence of different growing substrates (two mineral, two organic) on root xylem ABA concentration ([ABA](root)) and the contribution of the drying root system to total sap flow during partial rootzone drying (PRD), sunflower (Helianthus annuus L.) shoots were grafted onto the root systems of two plants grown in separate pots. Sap flow through each hypocotyl was measured be...
