Sensitivity of chickpea and faba bean to root-zone hypoxia, elevated ethylene, and carbon dioxide
During soil waterlogging, plants experience O2 deficits, elevated ethylene, and high CO2 in the root‐zone. The effects on chickpea (Cicer arietinum L.) and faba bean (Vicia faba L.) of ethylene (2 μL L−1), CO2 (2–20% v/v) or deoxygenated stagnant solution were evaluated. Ethylene and high CO2 reduced root growth of both species, but O2 deficiency had the most damaging effect and especially so for chickpea. Chickpea suffered root tip death when in deoxygenated stagnant solution. High CO2...[Show more]
