Morphoanatomical, Physiological, and Biochemical Indicators in Lactuca sativa L. Germination and Growth in Response to Fluoride.

ABSTRACT: Fluoride is one of the main phytotoxic environmental pollutants, and high concentrations (10-30 mg L-1) are commonly detected in surface and groundwater. Little, however, is known about the effects of this pollutant on crops that require irrigation during their development, which, in addition to phytotoxicity, may cause negative human health effects. Thus, the aim of this study was to characterize the effects of potassium fluoride (KF) on the germination of lettuce seeds and identify the physiological and anatomical markers of this pollutant's action on plants exposed to it during growth. Initially, lettuce seeds were sown in gerboxes and soaked in solutions containing 0 mg L-1, 10 mg L-1, 20 mg L-1, and 30 mg L-1 KF. Plants grown in a greenhouse were treated daily with KF irrigation at th
