Abstract
Abstract A foliar application of 5 × 10−5 M phenylmercuric acetate plus a wetting agent reduced water loss by transpiration from chrysanthemum plants by more than 30% for a period of 4 days following treatment without causing tissue damage or inhibiting growth and flowering. This reduction of transpiration was associated with a reduction of stomatal pore size. However, treatment concentration was critical, as foliar damage and reduction in growth occurred at high concentrations of PMA.
