Such a drastic decrease was
not observed for the canola and wheat plants. In the
cotton, canola and wheat plants without Si treatment,
the reduction in Ca2+ uptake by NaCN were 93%,
77% and 37%, respectively, less when compared to the
corresponding control plants. Saturating shoots with
water vapor reduced Ca2+ uptake more than Fe uptake
in canola and wheat; however, Ca2+ and Fe uptake
rates were decreased to a similar extent in cotton
by this treatment
