The distribution of leaf chloroplasts from tolerant
plants over the Percoll gradient after centrifugation
is shown in Fig 1. Using this method,
two intact chloroplast bands were obtained (frac-contents of chloroplasts did not show statistically
significant changes, whereas in sensitive plants the
chlorophyll concentration was significantly depressed
by NaCl (Table 3). Likewise, the PS II activity
of chloroplasts was only inhibited by NaCl
in the case of sensitive plants, whereas the protein
content of chloroplasts from both pea cultivars
was depressed (Table 3).
