Abstract
Cut foliages are one of the most important components of florist industry for use as fillers in bouquets, background and lining material in various flower arrangements. Asparagus and Dracaena are excellent cut foliages which are extensively used for this purpose due to their lush green foliage. An experiment entitled “Evaluation of Asparagus and Dracaena species for quality cut foliage and marketability ” was carried out at the experimental block of Division of Floriculture and Landscape Architecture, College of Horticulture, Bagalkot, Karnataka during the year 2018 - 2019. The experiment was conducted in Randomized Complete Block Design with five replications and four treatments in Asparagus and five treatments with four replication in Dracaena.
Among different species of ornamental Asparagus, Asparagus densiflorus ‘Sprengeri’ produces maximum plant spread (10210.65 cm2), maximum number of cladophylls per plant and per plot (61.21 and 129.33, respectively) and maximum leaf area index (4.91). Asparagus myriocladus produces maximum cladophyll stalk length (14.57 cm), stalk girth (2.70 cm), internodal length (4.43 cm) and fresh weight (24.14 g) and the maximum B C ratio of 5.26 : 1 was found in Asparagus densiflorus ‘Sprengeri’. Meanwhile, the maximum vase life of 15.24 days was recorded in A. densiflorus ‘Myers’ in treatment 10% Sucrose + 25ppm BA + 0.5% Boric acid.
Among Dracaena species, D. fragrans Victoriae recorded maximum plant spread (5846.93 cm2), maximum leaf area index (2.70) and leaf width (8.72 cm). D. massangeana recorded the maximum leaf length (51.45 cm), maximum leaf width (8.49 cm), and maximum fresh weight (10.54 g). Dracaena terminalis recorded maximum internodal length (1.31 cm) and the maximum B C ratio of 4.5 : 1 was found in D. fragrans Victoriae. Meanwhile, the maximum vase life of 32.74 days was recorded in D. fragrans Victoriae in treatment 10% Sucrose + 200ppm 8-HQC.
