Localized injury to plant organs from hydrogen fluoride and other acid gases

Journal Article:

Abstract

The origin of localized lesions from acid gases in smoke is discussed. The idea of corrosion is refuted. The action of acid gases in solution is analyzed for HCl on a numerical bases. With respect to HCl a more than hundredfold numerical error, constantly copied in the past, is corrected in a discussion of safe limits. Severe damage to leaves is reported from evaporating 0.001 molar HF solution. The border effect seen in leaves injured by HCl, HNO/sub 3/ or fluoric smoke is explained as due to an uneven uptake of acid gas in a distorted diffusion field, whereby a critical threshold is sooner reached along protruding edges. This phenomenon was studied in experiments with leaf models cut from indicator papers. Experiments with a fruit model showed that it may also account for localized injury to fruits hanging in the foliage and generally for the protective action at a distance observed in plants injured by fluoric smoke. It is suggested that the border reaction of indicator papers might be used for estimating the content of certain acid gases in the air. A hematein lake paper easily prepared was found to give a sensitive and specific reaction for HF in air.  More>>
