| Summary: | 碩士 === 國立屏東科技大學 === 農園生產系所 === 100 === In this research, Anthurium seedlngs were cultivated respectively in different substrate : coconut fiber, pearl barley shell, volcanic rock and the carbonized rice husk ash, and were inoculated with a mixed inoculum of six arbuscular mycorrhizal fungi（AMF）: Glomus clarum (Gc), G. etunicatum (Ge), G. fasciculatum (Gf), G. mosseae (Gm), Gigaspora sp.(Gig) and Acaulospora sp. (Asp) in the first trial. All Anthurium seedlings were cultivated in coconut fiber and were inoculated respectively with six species of AMF mentioned above in second trial. The plant growth, physiological characteristic, the total number and quality of cut flower and survival rate of Anthurium were investigated and evaluated for screening the most suitable cultivation substrate and AMF species using for the commercial cultivation.
The results in the first trial showed that, the mycorrhizal formation rate was at 5~46% in different substrate after inoculated with a mixed inoculum of AMF for 180 days. The plant height showed no significant difference among treatments after 270 days. The leaf width and leaf length had better performance while planted in the substrate of coconut fiber : pearl barley shell(7:1). The cut flower number of those AMF inoculation treatments (279 to 291 flowers) were better than that of the control (277 flowers). The cut flower quality of inoculated treatments present more M-Class or higher levels class. In the second trial, the mycorrhizal formation rate were from 25 to 74% after inoculated with six species of mycorrhizal fungi for 180 days. The plant height of Gig (47.27cm) and Ge (47.24cm) treatments were better than that of the control (43.74cm) after inoculation for 270 days. The petiole length of Gig (33.53cm) treatment was better than that of the control (30.57cm). On the performance of leaf width and leaf length, the inoculated treatments except Asp and Gc, were higher than that of control. On the cut flower production number, the Gc (122 flowers) treatment present the most flower number, followed by Gig (107 flowers), Gf (101 flowers) and non-inoculation control (95). On the performance of the cut flower quality, Gf (85 flowers) and Gc (84 flowers) treatments produced more M-class and higher levels class, accounting their ratio at 84.2% and 68.9% respectively. However, the non-inoculation control (61 flowers) showed the ratio at 64.2%. Athough the Asp treatment showed the highest mycorrhizal formation rate, but the performance of plant growth, flower production and quality were not satisfactory.
