Simulation of Atmospheric Humidity Uptake by the Aerial Roots of Plants

Abstract

Abstract:The mobilization of water by the plant is one of the main challenges of the moment given the threats of food insecurity whose main cause is climate change. The atmosphere contains moisture at any time of the year in the arid or semiarid zone. Apart from the underground roots naturally possessed by many plants, there are plants which possess exclusively or not aerial roots. In the search for methods of adapting crops to water stress, it is imperative to deepen knowledge about interaction between atmospheric humidity and the aerial roots of plants with respect to water absorption. Assuming transfer coefficients of the aerial roots homogeneous and taking into account the variability of the water potential of atmospheric humidity, simulations showed that relative air humidity, root size, and radial and axial transfer coefficients strongly influence radial and axial flows and therefore the amount of water absorbed by the roots.

Review on Dew Process and Its Contribution in Maize Water Requirement at Nalohou (Northern Benin)

“…The author first showed that the current trend of atmospheric humidity variation in Benin will remain unchanged for the RCP4.5 and RCP8.5 scenarios and will therefore available. Then, he studied the influence of the parameters (coefficient of diffusion of water vapor, duration of the exposure of the velamen to the humidity, the thickness of the velamen, the thickness of the boundary layer, and the temperature of the air surrounding the roots) on the adsorption, entry and migration of water molecules in the velamen [62,63]. He comes to the conclusion that:…”
