Slices cut from green, unripe fruit were treated by infiltration with aqueous solutions of 2,4�dichlorophenoxyacetic acid (2,4�D) and indoleacetic acid (lAA). 2,4.D delayed but increased the size of those peaks in respiration and ethylene production which are induced by cutting; ripening was also delayed. These effects were proportional to concentrations of 2,4.D in the range 1O-LlO-3M. Higher concentrations caused injury.

Naturally-established turkey oak (Quercus laevis Walt.) shoots were treated with aqueous solutions of the product picloram + 2,4-D (4-amino-3,5,6-trichloropicolinic acid + 2,4-dichlorophenoxyacetic acid) and with picloram pellets. Various application methods were utilized at several dates during the year. Responses measured 14 and 17 months after initial treatments were percent control of original shoots, percent regrowth, plant height, and live stems/plant. Leaf-stem-basal treatments provided the highest degree of control of any method studied, averaging 87% total shoot control over five treatments dates. Foliar, mist-blower, and leaf-stem applications showed no differences, averaging 75%, 79%, and 78% control, respectively. Basal applications gave poorest results averaging only 12% control over five dates. No differences were observed among treatment dates for applications made during the growing season after the full-leaf stage, but treatments made before full-leaf provided less control than others. Soil applications of picloram pellets were more effective when applied during the early spring and summer than during fall or winter but were less effective than treatments applied to foliage at all dates.

2,4 Dichlorophenoxyacetic Acid

Bananas were dipped in aqueous solutions of 2,4-dichlorophenoxyacetic acid (2,4-D) or indoleacetic acid (IAA) at concentrations ranging from 10-5 to 10-2M. Auxin, in proportion to its concentration, stimulated ethylene production; 10-2M and 1O-3M IAA and all 2,4-D concentrations advanced ripening relative to control fruit. 2,4-D at concentrations of 10-2M, 10-3M, and sometimes 10-4M stimulated the respiratory climacteric immediately after treatment, but ripening of the peel was delayed compared to the pulp.
