The effect of inclination bench and intermittent mist on the growth and production of Anthurium plant (Anthurium andraeanum)

Abstract


Anthurium andraeanum is an epiphyte with a habit of growth climbing. This plant has long duration of seed development and juvenile growth phase before flowering. A. andraeanum has 5 flowers per plant per year, with a variation from 0 to 7 flowers. The aims of this study are to determine the effect of intermittent mist and inclination bench on the growth and production of Anthurium in rock wool medium. This study uses cluster randomized design (RAK) 3 x 3 factorial pattern with 3 repetitions. There are three factors were tested in this experiment: 1) mist treatment (mist and control), 2) media type (bark and
granulous rock wool), 3) inclination angle of bench (0, 30 and 60 degrees). The investigations were leaf area, the number of inflorescence harvested, the spathe area, the fresh and dry weights. The results showed the plants with intermittent mist have bigger leaves and growth faster than control. Intermittent mist has
similar effect with relative humidity as in the native of A. andraeanum. The root of plants on the inclination bench 0° with intermittent mist contact a substrate, and attached or penetrate to the rock wool medium and grown down wards the medium and bench. All flowers from plants grown under intermittent mist classified as large flowers, with the average around 14.19 cm. Intermittent mist and medium influenced the fresh and dry weight of Anthurium. Plants with intermittent mist have the average 18.17gram fresh weight and control just 12.96 gram per plant. The structure, length, branching pattern and thickness of aerial roots varied depend on intermittent mist, medium and inclination bench have an effect to the growth and flowering of plants
