Abstract:In their natural environment, date palms are exposed to chronic
atmospheric ozone (O3) concentrations from local and remote sources. In
order to elucidate the consequences of this exposure, date palm saplings
were treated with ambient, 1.5 and 2.0 times ambient O3 for three months
in a free-air controlled exposure facility. Chronic O3 exposure reduced
carbohydrate contents in leaves and roots, but this effect was much
stronger in roots. Still, sucrose contents of both organs were
maintained at elevated O3, tho… Show more
