Leaf
K/Na ratio predicts salt induced yield loss in irrigated rice
|
|
A
field trial with 21 irrigated rice varieties for 7 seasons
|
|
At
the West Africa Rice Development Association, St. Louis, Senegal
|
|
fresh water control and
salinity at 3.5 mS cm-1
in neighboring plots
|
|
Na
and K was determined in the 3 youngest fully developed leaves in the
early vegetative stage. Yield was determined at maturity.
|
|
The
ratio between K and Na across the 3 youngest leaves allowed predicting
the yield loss due to salinity across genotypes and seasons.
