Commonly called asanthurium is an elegant, glossy surfaced flower. Very much famous among the top ten sold flowers due to its long shelf life and broad leaf spathe and spadix. A perennial evergreen herbaceous, semi terrestrial, epiphytic plant with somewhat creeping habit of growth, using aerial roots for anchorage. Belongs to familyaraceae and origin to tropical America (Columbia) with the chromosome of 2n=30.It is the national flower of Mauritius. It symbolize ‘hospitality’ among flowers. Anthuriums are often referred as “tail flower” which is derived from the Greek word ‘anthos’ means flower and ‘oura’ means tail referring to the spadix. The anthurium plant produces flowers throughout the year. Six to eight flowers are obtained per plant per year from the axil of every leaf. The ‘true’ flowers are found on the spadix and have large numbers of pistils, each surrounded by four stamens. The ‘true’ flowers are bisexual, protogynous and cross- pollinated. Six months after pollination, we can find colored berries on the spadix. Each berry contains one or two seeds that can be planted to generate new plants. Anthurium International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Volume 7 Number 04 (2018) Journal homepage: http://www.ijcmas.com Floriculture has been emerging as a future thrust industry in India and referred as tomorrow’s green cultivation. Importance of cut flowers in international flower market makes the growers to take up its cultivation in India. Globally, Anthurium ranks 11 th position among the cut flowers and 2 nd position among tropical cut flowers. In Karnataka, anthuriums are grown extensively in tropical humid regions viz., Kodagu and Chikkamagaluru districts (Mudigere) for Export purpose. An experiment was conducted during 2016-17 to investigate the effect of growth regulators (BA, GA 3 , MH, CCC) on suckering habit of Anthurium andreanum var. Tropical under naturally ventilated polyhouse. Results showed that benzyl adenine @ 750 ppm took least (88.67) days to sucker production. Which is on par with BA @ 500 ppm (90.33), BA @ 250and at the final stage of the experiment (at 240 days after spraying) number of suckers per plant was recorded in highest in BA @ 750 ppm (3.33).
