ABSTRACT
The current study, entitled “Studies on Postharvest Handling of Clarkia amonea (Lehm.)
A. Nelson & J.F. Macbr,” was carried out during 2020-21 in the Department of Floriculture and
Landscape Architecture of Dr. YS Parmar University of Horticulture and Forestry, Nauni, Solan
(H.P.). The study comprised of two postharvest experiments to standardized different pulsing and
holding solution(s) to increase the vase life of godetia (Clarkia amoena). The pulsing experiment was
laid out in completely randomized design with 13 treatments and replicated thrice. Under this
experiment sucrose (4 %), 8-HQC (200 and 300 ppm) and BA (15 ppm) were used in different
combinations for 2, 4 and 6 hours. It may be concluded that pulsing treatment of sucrose (4%) + 8-
HQC (300 ppm) + BA (15 ppm) for 6 hours was found best in relation to vase life, amount of solution
consumed, percent weight loss, early floret opening and with better overall presentability of godetia
cut flowers. Second experiment of holding solutions was laid out under completely randomized
design (factorial) with 13 treatments in which sucrose (2%), 8-HQC (100 and 200 ppm) and BA (5,
10, 15 ppm) were used in different combinations with 3 de-leafing treatments. It was observed that
holding solution of sucrose (2%) + 8-HQC (100 ppm) + BA (10 ppm) was concluded best regarding
vase life, flower diameter, percent weight loss, early floret opening and good overall presentability of
godetia cut flowers. In the present investigation, it is observed that de-leafing of cut stems after 6
inches from top was found best with longest vase life and better presentability of godetia cut flowers.
