Abstract

Kelapa sawit (Elaeis guineensis Jacq.) merupakan komoditas perkebunan penting yang berkontribusi besar bagi perekonomian Indonesia (Turnip, 2019; Gurusinga et al., 2022). Namun, dalam beberapa dekade terakhir, produktivitasnya menurun akibat penyakit Busuk Pangkal Batang (BPB) yang disebabkan oleh infeksi Ganoderma boninense (Susanto et al., 2013). Sebagai alternatif, media hidroponik digunakan untuk mempelajari infeksi patogen dalam lingkungan yang terkontrol (Putri et al., 2023; Natalia et al., 2017). Penelitian ini bertujuan untuk mengetahui anatomi organ, batang, dan daun kelapa sawit (Elaeis guineensis Jacq.) yang terinfeksi jamur Ganoderma boninense melalui Rubber Wood Block (RWB) pada media hidroponik. Pengamatan dilakukan selama dua minggu pasca infeksi menggunakan metode parafin dan Scanning Electron Microscope (SEM). Data dianalisis secara deskriptif kualitatif dan kuantitatif berdasarkan perubahan struktur dan ukuran diameter jaringan. Hasil yang didapatkan menunjukkan peningkatan diameter pada seluruh jaringan setelah terinfeksi Ganoderma boninense baik pada organ akar, batang, maupun daun. Pada akar, selisih rata-rata diameter antara tanaman kontrol dan perlakuan RWB dengan menunjukkan peningkatan pada epidermis sebesar 3,98 µm, endodermis 4,78 µm, xilem 13,21 µm, dan floem 8,83 µm, dengan hifa terdeteksi sejak 204 HST. Pada batang, peningkatan terjadi pada epidermis sebesar +6,81 µm, korteks 666,5 µm, xilem 43,59 µm, dan floem 35,72 µm, dengan hifa terdeteksi pada 207 HST. Pada daun, peningkatan terjadi pada epidermis sebesar 2,81 µm, korteks 63,33 µm, xilem 9,85 µm, dan floem 3,47 µm, dengan hifa terdeteksi pada 216 HST.

Oil palm (Elaeis guineensis Jacq.) is an important plantation commodity that contributes significantly to the Indonesian economy (Turnip, 2019; Gurusinga et al., 2022). However, in recent decades, its productivity has declined due to basal stem rot (BPB) disease caused by Ganoderma boninense infection (Susanto et al., 2013). As an alternative, hydroponic media is used to study pathogen infections in a controlled environment (Putri et al., 2023; Natalia et al., 2017). This study aims to determine the anatomy of oil palm (Elaeis guineensis Jacq.) organs, stems, and leaves infected with Ganoderma boninense fungus through Rubber Wood Block (RWB) in hydroponic media. Observations were carried out for two weeks after infection using paraffin and Scanning Electron Microscope (SEM) methods. Data were analyzed descriptively qualitatively and quantitatively based on changes in structure and tissue diameter size. The results obtained showed an increase in diameter in all tissues after being infected with Ganoderma boninense in both roots, stems, and leaves. In the roots, the difference in average diameter between control plants and RWB treatment showed an increase in epidermis of 3.98 µm, endodermis 4.78 µm, xylem 13.21 µm, and phloem 8.83 µm, with hyphae detected since 204 DAP. In the stems, an increase occurred in epidermis of 6.81 µm, cortex 666.5 µm, xylem 43.59 µm, and phloem 35.72 µm, with hyphae detected at 207 DAP. In leaves, increases occurred in the epidermis by 2.81 µm, cortex 63.33 µm, xylem 9.85 µm, and phloem 3.47 µm, with hyphae detected at 216 HST.
