Description Gerbera is one of the important commercial cut flower crops. It is one among the
top ten cut flower of the world flower trade, which ranks fifth in the International flower
trade. There is always demand for novel types with high yielding genotypes. Hence, the
present study was conducted to identify the suitable gerbera cultivars under naturally
ventilated polyhouse with respect to yield and quality cut flowers at Saidapur Farm in
Hi-tech Floriculture Unit, Main Agricultural Research Station, University of Agricultural
Sciences, Dharwad and also to find out the best chemical preservative for enhancing the
vase life of gerbera cut flowers.
Among the eleven cultivars studied there were wide and highly significant
variations observed for various growth, floral, cut flower yield and quality parameters.
The Cv. Lexus (38.82) produced maximum number of quality cut flowers followed by
Alberino (37.20), Scilla (36.95) and Bonnie (31.26). The same cultivars were also
produced the longest stalk length, bigger sized flowers and number of ray florets
compare to other cultivars. With respect to vegetative parameters like number of leaves
per plant, plant spread, suckers production, leaf area and leaf area index were also
maximum in the same cultivars. The positive correlation was noticed between flower
yield per plant, flower diameter, stalk length and length of ray florets. Similarly plant
spread and number of leaves also showed positively and significant association with
flower yield, flower diameter and length of ray florets.
The Cv. ‘Lexus’ realized maximum net return of Rs. 2,70,672 in 560m2 area with
a B:C ratio of 2.65 followed by Alberino (Rs. 2,55,120; 2.50), Scilla (Rs. 2,52,720; 2.48)
and Bonnie (Rs. 1,98, 096 ; 1.94) compared to other genotypes studied.
In vase life study among the chemical preservatives (viz., citric acid, silver
nitrate, aluminum sulphate, calcium nitrate and 8-HQS) tried citric acid @ 200ppm
recorded maximum vase life of gerbera (11.48 days) followed by AgNO3 @ 400ppm
(10.9 days).
