3-Amino-1,2,4-triazole prolongs carnation vase life.

Continuous postharvest treatment of White Sim carnation flowers (cv. Elliott's White) with 50 or 100 mM aminotriazole [amitrole] significantly extended vase life relative to flowers held in distilled H2O. No morphological changes symptomatic of floral senescence appeared in treated flowers until 12-15 days after harvest. The longevity of treated flowers was extended to approx equal to 18 days. The respiratory rate of treated carnations was suppressed, and they exhibited no respiratory climacteric throughout the period of observation. The responsiveness of treated flowers to exogenous ethylene appeared to be temporally regulated. Flowers treated with 50 mM aminotriazole for 2 days senesced in response to application of 10 micro l exogenous ethylene/litre, whereas flowers treated for more than or equal to 4 days exhibited no morphological response to ethylene treatment.
