Abstract
The effect of paclobutrazol and cycocel on growth and
flowering of annual chrysanthemum (Chrysanthemum coronarium
L.) Cv. 'Local White' was studied during the year 2004 at
Regional Horticultural Research Station, ASPEE College of
Horticulture and Forestry, Navsari Agricultural University,
Navsari. The treatments comprised of two different
concentrations (l00 and 200 mgll) of paclobutrazol and two
concentration of cycocel (500 and 1000 mgll) with three methods
of application (root dipping, soil drenching and foliar spray). The
experiment was laid out in Randomized Block Design (RBD) with
13 treatments including control.
The results revealed that an application of
paclobutrazol @ 100 mgll as soil drench reduced the plant height
(72.5cm), stalk length (4.7 cm) and vase life (7.0 days), while
days to first flower initiation being (55.7 days) and 50 per cent
! flowering (71.7 days) were obtain with an application of
, paclobutrazol @ 100 mg/l as root dipping method. While plant

The maximum weight of single flower (3.6 g), number
of pi cking (17 .5), number of flower per plant (165.0) and yield
per hectare (34 .2 t) were obtained with drenching of
paclobutrazol @ 100 mg/I.
In general, it can be concluded that application of
paclobutrazol @ 100 mg/l as soil drenching was proved to be the
best in improving the yield and also economically profitable in
annual chrysanthemum.
