Plants of the tetraploid cotton species Gossypium hirsutum L. ordinarily produce secondary shoots only from axillary buds. Destruction of the primary shoot by excision below the cotyledonary axils occasionally leads to the production of adventitious shoots. Two plants of the cultivar Coker 201 produced adventitious shoots from what appeared to be callus tissue growing outward from stem cambium after 12 plants had been severed at the ground line. A plant of the “honseyard” stock Orinoco produced several shoots from globular masses of tissue that grew from the roots after the shoot was removed. Another plant of Orinoco, grown from seed produced on the first, produced shoots at two sites near the ground line of a stump from which the trunk had been removed. After removal of the shoots, the plant grew three additional groups of shoots, including one group from a root about 2 cm from the stump.
