Sifting different varieties of wheat to withstand drought
Abstract
In laboratory conditions large variation was observed for
percentage of germination, elongation of plumule and radicale for
wheat varieties (Astoraly, Abaa 95, Abaa 99, Al- Tahady, Abograb
and Tamooze -2).
The percentage of germination was significantly and
progressively reduced with increase in the drought stress by using
different increasing of manitol concentration from (-4 to -12 bar). The
varieties showed differential response to percentage of germination
and elongation of plumule and radicale.
The variety Astoraly was found to be the most droughts tolerant
at germination. The plumule and radicale showed differential drought
tolerance.
The radicale was found to be less sensitive to drought than the
plumule at seedling stage.
