Summary
The growth and water requirements of ten of the native and introduced range species were compared at different levels of moisture stress between the permanent wilting percentage and the moisture equivalent.
The most vigorous vegetative growth and highest dry matter production were shown byChloris gayana.
The transpiration intensity of all the studied species was low and comparable with that of xerophytes living under extremely dry conditions. At the highest moisture stress which is a xeric condition, the transpiration intensity varied between 90 mg/g.h inOnonis vaginalis and 160 mg/g.h inPanicum antidotale.
The osmotic pressure varied widely between 16.5 atm inPennisetum dichotomum and 30.0 atm inOryzopsis miliacea at the highest moisture stress.
The present investigation revealed that all the studied species are drought resistant as shown by their transpiration intensity and osmotic pressure which are comparable with those of xerophytes. SinceChloris gayana exhibits the highest dry matter production in addition to its drought resistance therefore it can be considered as the most suitable species for cultivation in desert regions.
