Height control of Eschscholtzia californica using ancymidol, cycocel, and limited inductive photoperiod
<p>Limited 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, negati...

| Summary: | <p>Limited 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.</p>
