چکیده

AbstrakBakteri endofit yang terdapat di tanaman pisang Klutuk dan keterkaitannya dengan sifat ketahanan pada cekaman biotik abiotik belum dilaporkan dalam publikasi ilmiah. Sebanyak 93 isolat bakteri telah diperoleh dari Klutuk, tetapi diketahui kemampuannya sebagai pendukung pertumbuhan (PPT). Penelitian ini bertujuan untuk mengetahui karakter isolat-isolat tanaman. Kelompok Gram positif negatif ditentukan metode pewarnaan Gram. Kemampuan memfiksasi nitrogen (N2), memproduksi asam indol asetat (AIA), antagonisme terhadap Fusarium oxysporum f. sp. cubense (Foc) diuji kemampuan Hasil penelitian menunjukkan bahwa 87,10% merupakan kelompok 82,80% (77 bakteri) tunggal atau ganda PPT. Di tersebut, berturut-turut 60, 38, 20 mampu N2, menghasilkan AIA, Foc. pengujian didominasi oleh memiliki tanaman.Abstract The role of endophytic bacteria on the biotic and abiotic resistance banana plants has never been reported. A total bacterial isolates were obtained from in a previous study, but their potency as Plant Growth Promoting Bacteria (PGPB) is not elucidated. This study aims to characterize those isolates. staining was performed differentiate between Gram-positive negative among ability fix produce indole acetic acid (IAA) antagonize also examined determine PGPB. results showed that 87.1% Gram-negative 83.87% (78 isolates) had single or multiple traits Among isolates, able IAA, Foc, respectively. indicated inhabiting plant are dominated by
