Y. Hu et U. Schmidhalter, A two-pinhole technique to determine distribution profiles of relative elemental growth rates in the growth zone of grass leaves, AUST J PLAN, 27(12), 2000, pp. 1187-1190
A new modified pricking technique, a two-pinhole method, was designed to de
termine the spatial distribution of leaf elongation of grasses. This new te
chnique makes it possible to obtain the distribution profiles of relative e
lemental growth rates in the growth zone, to evaluate the effect of prickin
g on the distribution profile of leaf elongation in the growth zone and to
decrease the reduction in the elongation rate of grass leaves due to pricki
ng.
