Figure 2 High light intensity enhances the salt toxicity in tobacco seedlings 3. RESULTS AND DISCUSSION...

Several factors affect the salt sensitivity of plants. We first evaluated the effect of light intensity on the salt-stress. Figure 2 clearly showed that tobacco seedlings were more severely affected by salt stress under high light intensity both on the basis of chlorophyll content and fresh wei t increase. This result indicated that light, probably photosynthetic process, would be involved in the salt-stress. To characterize the salt-stress mechanism, we examine the effect of salt on the photosynthetic activities of isolated thylakoid membranes. Previously, we reported that the presence of salt in assay inhibited the photosystem II activity of tobacco thylakoid membranes but not photosystem I activities (Murota et al., 1994). Then, we further examined the effect of salt on the irreversible photodamage of thylakoid membrane activity.
