Abstract
Gerbera is one of the important commercial cut flower crops. It is
one among the top ten cut flower of the world flower trade. There is
always demand for novel types with high yielding genotypes. Hence, the
present study was conducted to identify the suitable gerbera genotypes
under naturally ventilated polyhouse in hill zone, with respect to yield
and quality cut flowers and also to find out the best chemical
preservative for enhancing the vase life of gerbera cut flowers in the
Department of Floriculture and Landscape Architecture, College of
Horticulture, Mudigere.
Among the ten genotypes studied there were wide and highly
significant variations observed for various growth, floral, cut flower yield
and quality parameters. The genotype Naike (38.01) produced maximum
number of quality cut flowers and was statistically on par with Kyllian
(36.94) and significantly superior over other genotypes. The genotype
Amlet produced the longest stalk length, bigger sized flowers were
produced by Kyllian and Vilassar and the genotype Elite Produced
maximum number of ray florets compare to other genotypes. The
vegetative parameters like number of leaves per plant, suckers
production and total leaf chlorophyll content was maximum in the
genotype Naike, where as plant spread, leaf area and leaf area index were
maximum in the genotype Amelie.
The genotype ‘Naike’ realized maximum net return of 2,39,894
in 560 m2 area with a B:C ratio of 2.35 followed by Kyllian ( 2,30,294;
2.25, respectively) and Amlet ( 2,20,754; 2.16, respectively) compared to
other genotypes studied.
The vase life study was carried out with the genotype ‘Naike’ which
had less lasting ability (5.55 days) in tap water. Among the chemical
preservatives (viz., citric acid, cobalt chloride and 8-HQS) tried, citric
acid @ 200ppm recorded maximum vase life of gerbera (9.16 days)
followed by citric acid @ 150 ppm ( 8.45 days ) and cobalt chloride @ 200
ppm (8.31 days).
