3-Amino-1,2,4-triazole Prolongs Carnation Vase Life

Abstract

<jats:p>Continuous postharvest treatment of carnation flowers <jats:italic>(Dianthus caryophyllus</jats:italic> L. cv. Elliot's White) with 50 or 100 mM aminotriazole significantly extended useful vase life relative to flowers held in distilled H<jats:sub>2</jats:sub>O. No morphological changes symptomatic of floral senescence appeared in treated flowers until 12 to 15 days after harvest. The longevity of aminotriazole-treated flowers was extended to ≈18 days. The respiratory rate of aminotriazole-treated carnations was suppressed, and they exhibited no respiratory climacteric throughout the period of observation. The responsiveness of aminotriazole-treated flowers to exogenous ethylene appeared temporally regulated. Flowers treated with 50 mM aminotriazole for 2 days senesced in response to application of 10 μl exogenous ethylene/liter, whereas flowers treated for 24 days exhibited no morphological response to ethylene treatment. Chemical name used: 3-1H-amino-1,2,4-triazole-1-yl (aminotriazole).</jats:p>

Murburn Concept: A Molecular Explanation for Hormetic and Idiosyncratic Dose Responses

“… 63 Amitrol has been demonstrated to improve vase life of carnation flowers. 64 These 2 molecules were probed for a heme-assisted hormetic effect on the growth curve of bacterial culture. The findings of this work afford a molecular basis for hormesis.…”

“…Derivatives of 1,2,4-triazole have significant importance for their broad-spectrum biological and pharmacological activities, such as fungicidal, herbicidal, anticonvulsant, antitumoral, inhibition of cholesterol (Chai et al, 2003;Kanazawa et al, 1988;Hashimoto et al, 1990). In addition, they have many applications in the agriculture domain (Altman & Solomost, 1993). In this paper, we report the synthesis and crystal structure of the title compound, (I).…”

“…The aminotriazoles are crucial heterocyclic substances which have a great interest thanks to their biological and pharmacological activity (Kanazawa et al, 1988;Hashimoto et al, 1990) such as antitumoral and inhibition of cholesterol activity. In addition they have many applications in agriculture domain (Altman et al, 1993). Aminotriazole are useful binucleophilic agents that lead to polycondensed heterocycles (Genady et al, 2003;Karanik et al, 2003).…”
