Effect of Water Movement on Salt Movement through Tomato Roots



IN recent years, there has been renewed debate concerning the effect of water absorption on salt absorption through the roots of intact plants. Salt absorption is regarded by many workers as involving active transport into the xylem by a mechanism dependent on energy released in respiration1–3. According to this view, water movement through roots affects salt movement only indirectly by removing salt from the root xylem and thereby producing conditions favourable for increased movement of salt by active transport. On the other hand, several investigators have concluded that, in rapidly transpiring plants, salt moves into the root xylem by mass flow as well as by active transport4–6.
