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/varieties for production of quality cut foliage under shade net condition” was carried out at the experimental block of Division of Floriculture and Landscape Architecture, College of Horticulture, Bagalkot, Karnataka during the year 2017 - 2018. The experiment was conducted in Randomized Complete Block Design five replications with four treatments in Asparagus and five treatments with four replication in Dracaena. Among different species/varieties of ornamental Asparagus, Asparagus densiflorus „Sprengeri‟ produces maximum plant spread (4094.61 cm2), maximum number of cladophylls per plant (75.56) and maximum leaf area index (4.69). However, maximum cladophyll length (80.44 cm), stalk length (14.34 cm), stalk girth (2.61 cm), internodal length (4.36 cm) and fresh weight (23.00 g) recorded in Asparagus myriocladus.
Among Dracaena, Dracaena terminalis performed maximum plant spread (3886.28 cm2), plant height (72.81 cm), internodal length (1.15 cm). Dracaena massangeana recorded the maximum leaf length (47.20 cm), leaf width (8.85 cm) and fresh weight (10.65 g) but minimum plant height (38.41 cm) and least number of leaves per plant (23.49). Pulsing treatment with 10 % Sucrose + 200 ppm 8-HQC significantly improved the vase life of Asparagus densiflorus Sprengeri (11.87 days). Likewise pulsing with 10 % Sucrose + 25 ppm BA increased the vase life (29.61 days) in Dracaena terminalis.
