Summary
Dry weight of topgrowth, water content of topgrowth, leaf nitrogen content, and leaf chlorophyll content were measured in well-watered, field-exposed little bluestem (Schizachyrium scoparium Nash.) and mountain brome (Bromus marginatus Nees.) plants fumigated with various mean levels of H2S ranging from 0.05 to 3.58 ppM. The youngest fully expanded leaves were sampled for chlorophyll content after 60, 80, 100, and 140 and 60, 80, 120, and 140 h total of fumigation for little bluestem and mountain brome, respectively. All other responses were measured after 140 h total of fumigation. The plants received a 7-day fumigation-free period prior to the seventh week (140 h) of fumigations. Dry weight of little bluestem plants which received low concentrations of H2S (0.11 ppM) increased by 94% of the control. Dry weight of little bluestem plants which received higher concentrations of H2S (0.12 to 0.48 ppM) was reduced to the control level. At the highest H2S concentration (2.39 ppM) dry weight of little bluestem was reduced by 44% of the control. Mountain brome was relatively unaffected at the different concentrations of H2S until 3.58 ppM H2S was received where dry weight was reduced by 37% of the control.
