From: Carbon nanotubes in the holding solution stimulate flower opening and prolong vase life in carnation
Flower diameter during vase life as a function of different concentrations of single- or multi-walled carbon nanotubes (left and right panels, respectively) in the holding solution of three cut carnation cultivars (A, B: Grand Slam; C, D: White liberty; E, F: Kirsi; Experiment 1). Values are the mean of 10 flowers ± sem. Statistics are provided in Additional file 2: Tables S1–S6
