ABSTRACT
“Studies on the effect of types of propagule on cut flower production of chrysanthemum
(Dendranthema grandiflora Tzvelev.)” was carried out during the year 2014 in the Department of
Floriculture and Landscape Architecture of Dr. Yashwant Singh Parmar University of Horticulture
and Forestry, Nauni, Solan (H.P.). Experiment was laid out in Randomized Block Design (factorial)
with six propagules types on two cultivars ‘Purnima’ and ‘Yellow Star’ and replicated thrice.
Significant differences were obtained among the cultivars for all vegetative and floral parameters.
Maximum height (99.06 cm) was obtained in ‘Yellow Star’ when propagule type was tip cutting taken
from secondary shoots arising from previous year plant. The number of side shoots per plant (3.34)
was maximum in ‘Purnima’ when propagule type was suckers taken from previous year plant.
‘Purnima’ showed maximum length of side shoots per plant (35.71 cm) when tip cutting taken from
secondary shoots arising from previous year plant. Maximum plant spread was obtained in ‘Yellow
Star’ (27.78 cm) when propagule type was suckers taken from previous year plant. Minimum number
of days taken for visible bud formation 78 days was noticed in cultivar ‘Purnima’ when propagule
type was tip cutting taken from primary shoot of stock plant. Days taken for peak flowering was
minimum 99.00 days in ‘Yellow Star’ when propagule type was tip cutting taken from lateral shoots
arising from previous year plants. Maximum numbers of flowers per plant was obtained in ‘Yellow
Star’ (2.67) when propagule type was suckers taken from previous year plant. Maximum duration of
flowering was obtained in ‘Purnima’ (22.00 days) when propagule type was sucker taken from
previous year plant. Maximum flower size in 13.24 cm and vase life (19.33 days) was observed in
‘Purnima’. Based on the findings, it was concluded that cuttings can be harvested from mother plants
for three times in succession at monthly intervals.
