This reduction in ATP synthesis is due to decreased electron transport and photophosphorylation
caused by the loss of membrane-associated reactions.
These are two basic reactions in photosynthesis: photolysis, or the so-called Hill reaction, and photophosphorylation

It mean that 17.95 [micro]mol [photons.sup.-1] being required for fixation of 1 [micro]mol C[O.sub.2] for seedlings submitted to stem bendings, 22.32 [micro]mol [photons.sup.-1] [micro]mol C[O.sub.2.sup.-1] in the seedlings submitted to JA and 22.72 [micro]mol [photons.sup.-1] Lmol C[O.sub.2.sup.-1] in control seedlings respectively, evidencing an increase in the photophosphorylation
efficiency promoted by mechanical disturbances.
N-Phenylcarbamates with [R.sup.1] = 3,4-[Cl.sub.2][C.sub.6][H.sub.3] and [R.sup.2] = 4-N[O.sub.2][C.sup.6][H.sub.4], C[H.sub.2]CH[Cl.sub.2], or [CH.sub.2]C[F.sub.3] were found to be potent uncouplers which were able to fully uncouple the oxidative phosphorylation or the photophosphorylation
between 1 and 10 [micro]mol/L.
