Abstract
The roots of Allium cepa were allowed to grow in distilled water containing 10(-4) M adrenaline hydrochloride or 2 X 10(-3) M hydrocortisone sodium succinate. Adrenaline inhibited the growth of roots; they decreased in length, number and total dry weight. The total amount of DNA in the roots was reduced much less than that of extracellular root components after adrenaline. Also hydrocortisone treatment resulted in a considerable decrease of the length and dry weight of Allium cepa roots. Both DNA and extracellular root components were influenced.
