Grass Seedling Response to Wind and Windblown Sand1

Rangeland glasses are difficult to establish on sandy soils because blowing sand can kill young seedlings. Four grass species, sideoats grama [Boitteloua curtipendula (Michx.) Torr.], cane bluestem [Bothriochloa barbinodis (Lag.) Herter], green sprangletop [Leptochloa dubia (H.B.K.) Nees], and sand bluestem (Andropogon hallii Hack.) were grown in a greenhouse and subjected to wind and wind with sand in a laboratory wind tunnel. The blowing sand killed the seedlings or retarded their growth, but wind alone had little influence. With increasing age, the young grass plants became more tolerant to wind and sand damage. Plant growth was slowed because the blowing sand ruptured plant cells, dried out the exposed tissue, and exposed the damaged seedlings to diseases and insects.
