Method and device for determining the vase-life of cut-flowers by plant acoustics

Abstract

The invention provides a method for estimating a vase-life of a cut plant product (1), wherein the cut plant product (1) is selected from the group comprising a cut flower and cut foliage, wherein the method comprises: (A) a cooling stage comprising subjecting the cut plant product (1) to a cooling temperature (Tc) for a cooling duration (tc), wherein the cooling temperature (Tc) is selected from the range of 0 — 10 °C, and wherein the cooling duration (tc) 10 is selected from the range of 0.5 — 4 weeks; (B) a detection stage comprising detecting acoustic emission radiation (2) from the cut plant product (1) and providing an emission-related signal (3), and (C) an analysis stage comprising determining a settling time (Is) based on the emissionrelated signal (3), and determining the vase-life based on the settling time (Is).
