Abstract
THERE are very few reports concerned with the effects of internal radioisotopes on the growth of plants. The growth of lateral roots of Zea mays is stopped with the addition of 10 µCi ml.−1 of 3H-thymidine1, whereas generally the growth of plants as a whole is not disturbed by doses of radioisotopes normally used for biochemical studies, even though injury, or even growth stimulation may occur in some cases2.
