Abstract

HITCHCOCK and Zimmerman1 induced responses in the shoots of tomato and tobacco plants by applying a solution of hetero-auxin to the soil. These responses included bending, swelling, the production of adventitious roots on the stems, and epinasty of the leaves. This letter describes the relative effect of adding small amounts of hetero-auxin to the culture solution bathing the roots, and spraying approximately the same quantity on the shoots by the method described by Pearse2. Vicia Faba (Dobbie's Champion Long Pod) was used as the test plant, and the seedlings were three weeks old at the time of the first applications of hetero-auxin ; the shoots were then about 10 cm. high. Fig. 1 shows the result of one week's treatment ; the plants on the left were sprayed daily with 1 c.c. of a 0.01 per cent solution of hetero-auxin, those in the centre are the controls, while those on the right were supplied daily with 1 c.c. of a 0.01 per cent solution in 500 c.c. of culture solution.
