Abstract
The present study was under taken in a commercial floriculture farm under protected cultivation with three cultivarsof carnation during July 2010 to February 2011. The experiment was laid out in randomized block design with factorialconcept. Harvesting of carnation flower stalk at 10 cm height from the ground level recorded minimum number of days to sprouting of buds than other harvesting heights i.e., 5, 15 and 20 cm height. Days to first flower bud appearance, color break stage and days to harvest was also minimum with harvesting at 10 cm height in cultivars Domingo, Dover and Keiro. And the length of lateral, length of flower stalk and flower, diameter of flower stalk and flower, number of flower stalks per plant, fresh flower weight and vase life was maximum with harvesting 10 cm height than other harvesting heights in cultivar Domingo.
Highlights
IntroductionIn India, carnations are being grown in places like Nasik, Pune, Jammu & Kashmir, Himachal Pradesh and surrounding areas of Hyderabad in Andhra Pradesh [3] Application of various special horticultural practices after standardization can be one of the means to achieve the target of quality flower production
Carnation (Dianthus caryophyllus Linn, Fy: Caryophyllaceae), has been extensively cultivated for cut flowers in Columbia, Japan, Israel, Netherlands etc., A study indicated that about 34% of the total flower consumers expressed their liking for carnation compared to only 20% of the people who favoured roses
Carnation flowers are harvested at different heights or at different nodes without knowing its impact on growth and flower production in successive crop
Summary
In India, carnations are being grown in places like Nasik, Pune, Jammu & Kashmir, Himachal Pradesh and surrounding areas of Hyderabad in Andhra Pradesh [3] Application of various special horticultural practices after standardization can be one of the means to achieve the target of quality flower production. Carnation is a plur annual commercial cut flower crop exhibits apical dominance and development of lateral shoots and flower production are influenced by the presence of apical dominance [4]. To induce early sprouting of buds and transformation of laterals, the levels of harvest plays an important role and have an impact on number of buds sprouting at the bottom or top of the left over harvested shoots, which determines the number of flower stalks produced per harvested stalk. Organized research work in these lines on commercial cultivars of carnation is not available
