Conteúdo: | 1. It is already known that moisture stress inhibits not only growth and dry weight accumulation of young tomato leaves but also the accumulation by such leaves of nitrogen and phosphorus. The present work has shown that moisture stress suppresses net increases in the RNA of such leaves. 2. The leaves of moisture stressed plants possess the ability to incorporate P32-labeled phosphate in RNA even though they do not exhibit ay net synthesis of the material. 3. It is concluded that in the leaves of moisture stressed tomato plants, rate of destruction of RNA may be increased above the rate characteristic of control, non moisture stressed leaves. This conclusion is further supported by the experimental increases rate of RNA loss in excised tomato leaves. We wish to acknowledge the advice and counsel of Dr. Kenneth Glasziou, Dr. Clifford Sato, Dr. Paul O.P. Ts'o and Dr. George G. Laties.
