The influence of hydrogen fluoride fumigation on water economy was studied using soybean (Glycine max [L] Merr.). Fumigation caused partial stomatal closure in 1 hour and practically complete closure within 4 hours. The transpiration rate was greatly reduced by fumigation, while the leaf temperature was increased. Water potential increased after 1 day but fell drastically when necrosis occurred. Effects of interrupted fumigation during the day were somewhat less severe in all respects than those of continuous fumigation; nighttime fumigation caused only minor effects. Fluoride uptake was also much less from nighttime than from daytime fumigations.
采用大豆（Glycine max [L] Merr.）研究了氟化氢熏蒸对水分平衡的影响。熏蒸1小时后导致部分气孔关闭，4小时内几乎完全关闭。熏蒸使蒸腾速率大幅降低，同时叶片温度升高。1天后水势升高，但发生坏死时水势急剧下降。白天中断熏蒸的影响在各方面都比连续熏蒸的影响稍轻；夜间熏蒸仅产生轻微影响。夜间的氟化物吸收量也比白天熏蒸时少得多。
