Wheat seeds after 15min plasma treatment had substantially heavier
roots (1.06 g) than the control samples (0.78 g). Sproutweightwas about
the same in both cases (0.88–0.89 g). There were considerable differ-
ences between root-to-shoot ratios: for the control sample the R/S ratio
was 0.88, while for the treated sample the value reached 1.2.
