Abstract
Buckwheat was sprayed with 50, 100, 500, and 1000 ppm. of 2,4-D and analyses made at intervals up to 8 days. Generally the effect increased with concn. Deformation, reduction in leaf area and chlorophyll, delay of flower bud opening, and decrease in dry wt. increased with concn. Total sugar T/C values in stems and leaves rose for a day but fell thereafter, while in roots the values fell continuously. Starch-dextrin T/C values in stems rose to maxima in 12 hrs. and declined rapidly. T/C values for total N and protein N in stems and roots increased with time and concn. Little change in these values occurred in leaves.This publication has 8 references indexed in Scilit:
