Effect of Acidity on Germination of Some Grasses and Alfalfa

Abstract

Germination of blue panicgrass, Lehmann lovegrass, buffelgrass, common bermudagrass, and alfalfa was studied in petri dishes containing sulfuric acid solutions ranging in pH from 7.0 to 1.0. Above pH 4.0 there was no significant decrease in percent germination. Lehmann lovegrass and common bermudagrass did not germinate at or below pH 3.0. Alfalfa and buffelgrass were the most acid tolerant species tested.
