Kamemoto, H. 1988a. dieffenbachiae (previously, X. campestris pv. The anthurium research program, initiated in Hawaii in 1950 by Dr. Haruyuki Kamemoto, led to the development of a breeding program for the commercial development and release of anthuriums to growers (30). 18). Anthurium is a popular house plant with more than 800 species. Growing best in low-light conditions, Anthurium are handsome exotics with shiny dark green, oblong, heart-shaped leaves. Appearance: It first appears as a dark ring around the spadix, then develops further and turns the entire spadix to dark brown or brown color. Scale insects are somewhat more difficult to get rid of and will require an organic pesticide. Trop. Anthurium roots are fleshy, appearing almost knobby or tuberous. 10. During the three years of production, 20% of the plants exhibited blight symptoms, causing the planting to be abandoned (48). 9 and 10). Signs: The commonly seen signs of bacterial wilt and blight are yellow leaves, water-soaked lesions among leaf tips, and yellow or brown dots on flowers. The genus Anthurium encompasses over 1,500 species, more than 600 of which originate from Tropical America (23,27). Use of symptomless cuttings for propagation is a risk even when propagative materials are grown at high elevation, so establishment of pathogen-free microplants in vitro is essential for large-scale anthurium production. You can propagate from air root cuttings or stem cuttingshere's how: You can also grow anthurium from seed; however, it can take up to four years before you see flowers, which might discourage those looking for a colorful plant. 35.
