Abstract:
An ecological study of Amorphophallus eburneus Bogn. was carried out at Gunung Rimau, Padawan. The density of A. eburneus was resoluted by establishing 5 plots of 20 m x 20 m, which was subdivided to 20 subplots (10m x 10 m). The total number of A. eburneus recorded was 239 plants, or 48 plants per plot. Field survey revealed that there were 36 tree species. The five most dominant species were Diospyros hermaphroditica (Zoll.) Bakh. Ex V. Steenis (IV = 45.56), followed by Grewia acuminata Juss. (IV = 27.59), Madhuca motleyana (De Vriese) Baehmi. (IV = 23-47), Azadiractha excelsa (Jack) Jacobs (IV = 21.86), and Scaphium macropodum (Miq.) Beumee ex. Heyne (IV = 17.30). Strong relationship in vegetative part of A. eburneus was recorded between petiole height and petiole diameter with R2 = 0.9173 (y= 2.0333x + 21.997). Study on the effects of shading (0%, 50% and 75% shading) on the development of A. eburneus was carried out at Faculty of Resource Science and Technology greenhouse. From the overall observation, A. eburneus grown under 75% shading regime showed the highest development on petiole height, petiole diameter, number of leaflets and length of leaflets. For biomass allocation analysis, A. eburneus grown under 7 5 % shading regime also recorded the highest value of leaf area determination (LAD), while A. eburneus grown under 50% shading regime recorded the highest value of dried mass production (DMP) and A. eburneus grown under 0% shading regime recorded the highest value of net rate absorption (NAR).
