Spray Carrier Volume Effects on XE-1019 and Chrysanthemums

Abstract

Plant of Chysanthemum morífolium Rymat. 'Ovaio' received 0, 102, 204, 304 or 408 ml-m⁻² of 0, 40, 20, 13.3, and 10 mg-liter⁻¹ XE-1019, respectively. No treatment affected time from start of short days to bloom or inflorescence display diameter. All XE-1019 treatments resulted in shorter plants than controls did. No carrier volume effect on plant height was observed. The inflorescence height range per pot decreased with increasing carrier volume. The greater inflorescence height uniformity achieved with the high carrier volume is beneficial and warrants further investigation.
