Abstract: | Nuclear magnetic resonance was used to detect thermal injury to chloroplasts in vivo. A lesion occurs in the chloroplast envelope membrane at temperatures between 53°C and 57°C, depending on species, leaf condition, and heating rate. The injury is associated with a sudden loss of water from the chloroplast. |
