The Phytotoxicity of Designated Pollutants

Abstract

The phytotoxicity of short exposures of gaseous hydrogen fluoride (HF) and of drenches of JP4 jet fuel were examined. Germination and growth of radish and tomato seeds were reduced when planting was delayed one or six hours after 20-minute exposures of the seeds to HF gas. Tomato seeds were more sensitive than radish. Barley, bean, and zinnia plants were exposed once to HF gas when six to 28 days old. Sensitivity of barley plants to injury from HF increased with age; beans were most sensitive when six or eight days old; zinnia sensitivity was not significantly affected by age at exposure. Plants were all harvested when 35 days old; weight and other biomass measures correlated well with plant age at exposure. Plants exposed at an early age never developed well, whereas plants exposed when older were not greatly reduced.
