Abstract

DPX 1840 [3,3a-dihydro-2-(p-methoxyphenyl)-8H-pyrazolo-(5,1-a)isoindol-8-one] modified xylem development in honey mesquite [Prosopis juliflora (Swartz) DC. var. glandulosa (Torr.) Cockerell] by causing the formation of an essentially fiberless wood. More than 90% of the axial cells on the xylem side of the vascular cambium differentiated as parenchyma. These cells contained large quantities of starch and were similar in structure to the sapwood parenchyma of untreated seedlings. DPX 1840 treatment also brought about the release of basal stem buds and may be potentially useful in woody brush control.
