Leaf abscission from Euphorbia milii ‘Gaia’,
Polyscias fruticosa ‘Elegans’, and Schefflera
arboricola ‘Gold Capella’ plants after a 14-d
display life at 21 C. Plants were treated with
0 (control) or 0.9 mLL–1 1-methylcyclopropene
(1-MCP) for 5 h at 21 C on Day 0 and packed
into boxes. Additional control plants were
placed into boxes containing two EthylBloc
sachets that released 1-MCP. All plants were
subjected to simulated shipment for 3 d at 15
C. They were then exposed to 0 or 1 mLL–1
ethylene for 4 d at 21 C before display life.
Data (mean ± SE, n = 5 to 8) for each genotype
followed by different letters are significantly
different at P = 0.05
