Temperature-Dependent Inhibitive Actions of
,
'-Dipyridyl and Cycloheximide on the Senescence of Maize Leaves
Biological Institute, Faculty of Science, Korea University Ogawa-Cho, Kodaira, Tokyo 187, Japan
Temperature-dependent inhibitive actions of
,
'-dipyridyl and cycloheximide on the senescence of maize leaves were studied.
,
'-Dipyridyl effectively inhibited the loss of chlorophyll at 25°C but not at 35°C. Gycloheximide was highly effective in preserving chlorophyll at both of 25 and 35°C. Spectral analysis of senescent leaves at 35°C in
,
'-dipyridyl showed simultaneous bleaching the carotenoid and chlorophyll.
