SKRIPSI PENGARUH APLIKASI CENDAWAN MIKORIZA ARBUSKULA DAN KOMPOSISI MEDIA TANAM TERHADAP PERTUMBUHAN PLANLET PISANG CAVENDISH PADA TAHAP AKLIMATISASI
ABSTRACT
The Effect of Arbuscular Mycorrizhal Fungi and Growth Media Composition on Acclimatization of Cavendish Plantlets Zahrani Nazla Fadila zahrani.nazla.fadila@students.untidar.ac.id Acclimatization phase is a critical stage for the growth of Cavendish planlets. This study aims to analyze the effects of arbuscular mycorrhizal fungi (AMF) application and growth media composition on Cavendish plantlets during acclimatization. The experiment was conducted at KBTPH Salaman over a two-month period using a completely randomized design (CRD), with the first factor being the dosage of AMF 0, 5, 10, 15, 20 g/plant and the second factor being the growth media composition namely husk charcoal : cocopeat : sand (M1); husk charcoal : cocopeat : soil (M2); husk charcoal : cocopeat : leaves compost (M3). Data collected were analyzed using ANOVA, followed by further testing with orthogonal polynomial and LSD tests. The results showed that both treatments enhanced plant height and stem diameter of Cavendish plantlets during acclimatization. A dosage of 14.85 g/plant of AMF increased plantlets height up to 7.69 cm, while a dosage of 12.97 g/plant increased stem diameter by up to 3.89 mm. These improvements in vegetative parameters were influenced by the AMF colonization fungi in the roots of Cavendish plantlets. This association is thought to enhance root capacity for absorbing P and N, which are essential for growth, cell division, and cell formation. Furthermore, growth media composition (M1 and M2) were found to improve both plant height and stem diameter of the plantlets. This suggests that growth media composition M1 has high porosity for root growth and M2 has good water retention capacity. In conclusion, AMF application combined with the appropriate growth media composition can significantly enhance the growth of Cavendish plantlets during the acclimatization.
