Abstract
Experiments were conducted to determine if there was a residual effect of the experimental plant growth regulator Ortho XE-1019, (E)-(P-chlorophenyl)-4,4-dimethyl-2-1,2,4-triazol-l-yl)-l-penten-3-01, remaining in Deltapine 50 and 90 cottonseed obtained at three harvest dates from experiments run at the University of Arizona Marana and Maricopa Agricultural Centers in 1986. Commercial DPL 50 seed were treated with XE-1019 in a second experiment. Several growth characteristics were measured including dry weights after 7 and 12 days. Hypocotyl length was not significantly different between treatments after 12 days of growth, with one exception, nor between dates of harvest for DPL 90 and DPL 50. Other measurements sometimes had statistical differences which were more academic but would be of little consequence in obtaining a satisfactory field stand. A significant reduction of hypocotyl length resulted when seed was directly treated with XE-1019 and would result in poor emergence. Results indicated that the use of XE-1019 as a plant growth regulator on cotton would not have significant residual responses on early seedling growth of Deltapine 90 and Deltapine 50 when the resulting seed are used for planting seed in the next generation.
