Comparaison de la nutrition minérale du mil (<i>Pennisetum glaucum</i> L.R. Br.) en présence de stress hydrique et de stress salin

Abstract: Objectif : L'amélioration de l'efficience de l'irrigation en s'orientant vers la détermination des besoins réels en eau des différentes cultures et aussi l'appel à l'irrigation déficiente ainsi que la possibilité d'utilisation des eaux salées pour l'irrigation sont parmi les décisions à instaurer en Tunisie pour préserver le capital eau qui se fait de plus en plus rare. Méthodologie et résultats : Ces techniques d'irrigation ont été appliquées sur une culture de mil afin de tester sa tolérance au manque d'eau … Show more

“…However, for tissue tolerance high salt concentrations are found in the leaves but are compartmentalized at the cellular and intracellular level, particularly in the vacuole [4]. This accumulation of mineral ions in the vacuoles allows plants to achieve osmotic adjustment and avoid physiological drought caused by salinity [5]. Our results show significant levels of Na + and Cl − in the leaves (Figures 1 and 2) and plead in favor of tissue tolerance.…”

“…The salinity tolerance mechanism of plants depends on how they control the transport of salt through their organs. It takes place by minimizing the entry of salt inside the plants or its concentration in the cell cytoplasm [5].…”

“…Water stress is reflected in the plant by a series of changes that affect morphological, physiological and biochemical characters, when the water needs of plant exceed the available quantities (Mefti et al, 2001). As a result, the physiological mechanism adopted in case of water stress can be an effective tool for differentiating between varieties (Radhouane, 2013). Indeed, tolerance to different stresses depends on species, varieties and even genotypes (Ullah et al, 2008).…”
