Opening Bud-Cut Standard Carnations Following Truck Shipment from Hoghlands to Bangkok
Abstract
‘Red Sim’ and ‘White Sim’ standard carnations were cut at bud stage from Chiang Mai highland production site pulsed and packed wet with silver thiosulfate or Physan-20 plus sucrose before shipping by truck to Bangkok. After arrival, they were opened in bud-opening solutions containing various concentrations of benzalkonium chloride plus sucrose. The best pulsing and bud-opening solution was found to be 200 ppm Physan-20+5% sucrose and 300 ppm benzalkonium chloride+5% sucrose respectively. Use of pulsing and bud-opening solutions with bud-cut carnations produced large blooms with short opening time, high percentage of bud opening and long vase life.
