| Abstract: | Young seedlings of Picea abies Karst, grown in nutrient solution were treated with the growth retardants Amo-1618, B-995, and CCC. These were added to the nutrient medium. B-995 and CCC retarded root and shoot growth in the concentrations 100, 10, and 1 mg/l. Growth was almost entirely inhibited by 300 mg/l, obviously due to toxicity. The effects of Amo-1618 were similar but more varying. GA counteracted the effects of all the retardants on shoot growth, but not on root growth. |
