Stomatal and nonstomatal responses of photosynthesis to water deficits and chilling.

摘要

his thesis deals with the nonstomatal and stomatal responses to photosynthesis to water deficits and chilling. Photophosphorylation was studied as a potential limitation since its fragile and highly integrated nature makes it a prime candidate for disruption by unfavorable environmental conditions and because it had been implicated in earlier in vitro results. In situ measurements of photophosphorylation were made using the flash-induced absorbance change at 518 nm, ;Low leaf water potentials (;Exposure of maize leaves to 4-6;Autoradiographic images showed that low
