dc.description.abstractLimited inductive photoperiod (LIP) significantly reduced stem length but had no effect on the peduncle length, leaf number, plant diameter, days from seed to first flower or days from start of long days (LD) to first flower in Eschscholtzia californica. However with fewer LD cycles, negative effects associated with LIP included an increasing number of bud abortions and plants remaining vegetative, while the number of axillary buds decreased. Ancymidol [alpha-cyclopropyl-alpha-(4-methoxyphenyl)-5- pyrimidinemethanol] at 35, 45 and 50 ppm reduced stem length, but had no effect on peduncle length. Although plant diameter was significantly reduced, ancymidol had no effect on number of leaves or days to flower. There were no bud abortions, all plants flowered successfully, and there was no negative effect on axillary bud number with the use of ancymidol. Cycocel [(2-chloroethyl) trimethylammonium chloride] had no effect on stem length or the overall plant height in the Eschscholtzia californica. In addition, cycocel proved to be ineffective on associated vegetative growth and reproductive development.en
