Ecology of amorphophallus borneenis at Gunung Gayu, Padawan
DiS1ribution of A. borneensis was resoluted by using 6 plots of 1 hectare (lOOm x 100m) and subdivided into 25 subplots (20m x 20m) at Gunung Gayu. The total ofA. borneensis in 6 plots was 138 plants with mean of 23 plants per hectare. Generally the plants occurred 2 to 4 meter from the large tree s...

| Summary: | DiS1ribution of A. borneensis was resoluted by using 6 plots of 1 hectare (lOOm x 100m) and subdivided into 25 subplots (20m x 20m) at Gunung Gayu. The total ofA. borneensis in 6 plots was 138 plants with mean of 23 plants per hectare. Generally the plants occurred 2 to 4 meter from the large tree such as Shorea macropyhl/um, Koompassia excelsa, Durio zibethinus and Baccaurea macrocarpa. A. borneensis surveyed at Gunung Gayu were ranged between 0.95mm -20.5mm above ground surface stem diameter with their height ranged between 120.5cmISO.
5cm. The dry weight of 32 plants ranged 4.5g -660g with the mean of 116.98g. Strong correlation in vegetative part of A. borneensis was between height and ground surface stem diameter (y = 34.41x + 29.80 which R2 = 0.899). For forest structure in Gunung Gayu, the most dominant species revealed in one hectare plot with the presence of A. borneensis, was Shorea macrophyl/um (IV = 64.21) and the range was followed by Durio zibethinus (IV = 21.87), Baccaurea macrocarpa (IV = 17.87), Baccaurea angulata (IV = 16.73), and Koompassia excelsa (IV = 15.18). The mean percentage of sand, which is 82 ± 0.8539% in soil composition, indicates that A. borneensis grows in well drained soil which can give well aerated for its root survive. |
