The objectives of the research presented in
this paper were 3-fold: 1) to investigate whether
the treatment of stock plants with ethylene has
any residual effect on time to flowering or
petal abscission in plants produced from cuttings
of these stock plants; 2) to determine the
sensitivity of four zonal geranium cultivars to
exogenous ethylene; and 3) to investigate the
effectiveness of 1-MCP at preventing petal
shattering in these cultivars.
