Photosynthesis and Carbonic Anhydrase Activity in Zn-deficient Peaches Irradiated with Ultraviolet Light1

Year: 1976

Type: article

Abstract: Effects of UV-B radiation (280-310 nm) and Zn deficiency on photosynthesis and carbonic anhydrase (CA) activity in peach seedlings ( Prunus persica (L.) Batsch) were studied. Low Zn markedly reduced CA activity; however, the reduction was not proportional to the reduction in leaf Zn content. Zn-deficient leaves irradiated with UV-B had lower CA activity, chlorophyll content, spectral reflectance and rates of photosynthesis. The reduction was more pronounced when leaves were distinctly chlorotic. Higher CA activity was not necessary for maintaining high rates of photosynthesis. Target areas in the leaf for UV-B absorption are discussed.
