Abstract
The present investigation entitled “Effect of bulb size and plant density on
growth, flowering and postharvest handling of Chincherinchee (Ornithogalum
thyrsoides Jacq.).” was carried out at Experimental Farm of the Department of
Floriculture and Landscaping, Dr. Yashwant Singh Parmar University of Horticulture
and Forestry, Nauni, Solan (H.P.) during the year 2008-2010. Two experiments were
conducted using randomized block design (factorial) in the field and completely
randomized design in laboratory, respectively. In the first experiment, the vegetative
growth parameters viz. days taken for sprouting (23.88, 23.71 days), plant height
(47.81, 48.11 cm), stem length (25.37, 26.09 cm), number of leaves per plant (17.74,
14.27), leaf area (25.21, 26.13 cm2); the flowering parameters namely days taken to
first floret opening (174.44 days), number of florets/stem (53.76, 55.38), cut stem
diameter (5.30 mm), cut flower weight (17.02, 17.26 g), vase life (14.52, 14.86 days),
duration of flowering (19.86, 21.26 days ); the bulb production parameters like
number of bulbs per plant (2.38, 1.99), weight of bulb(s) (8.94, 8.88 g), size of bulb
(2.88, 2.72 cm) were found maximum in 2.4-2.8 cm bulb size and 30 bulbs per
square meter density, respectively over others. Plant spread (23.78, 23.61 cm), size
of florets (1.76, 1.78 cm) were found maximum in 2.4-2.8 cm bulb size and 25 bulbs
per square density, respectively. In the second experiment, days taken for opening of
first floret (1.57, 1.36, 1.61 days), percent of unopened florets (14.51, 13.49, 13.28
%), weight loss (32.43, 31.55, 30.50 %) were found to be minimum whereas amount
of holding solution consumed (13.00, 13.84, 15.52 ml) and vase life (14.66, 14.90,
14.69 days) were maximum in 2.4-2.8 cm bulb size and 30 bulbs per square density
treated in holding solution comprising of sucrose (2%) + 8-HQC (200 ppm+ GA3 (50
ppm), respectively over control.
