INDUKSI KETAHANAN SISTEMIK PADA TANAMAN BAWANG MERAH (Allium ascalonicum) OLEH BAKTERI ENDOFIT YANG DIISOLASI DARI Platycerium elephantotis: INDUCED SYSTEMIC RESISTANCE IN SHALLOT (Allium ascalonicum) BY ENDOPHYTIC BACTERIA ISOLATED FROM Platycerium elephantotis Pamungkas, Bayu Aji; Aini, Luqman Qurata; Abadi, Abdul Latief; Syib`'li, Muhammad Akhid; Setiawan, Adi; Trianti, Irisa

Abstract

Produksi bawang merah dihadapkan pada kendala serangan organisme pengganggu tanaman (OPT). Pemberian bakteri endofit diduga dapat menginduksi ketahanan tanaman bawang merah. Penelitian ini bertujuan meningkatkan ketahanan dan produktivitas tanaman bawang merah melalui aplikasi bakteri endofit asal Platycerium elephantotis yang berpotensi sebagai Plant Growth Promoting Bacteria (PGPB). Penelitian ini dilakukan di Desa Dadaprejo, Kota Batu, dengan menggunakan varietas bawang merah Tajuk, yang ditanam menggunakan rancangan acak kelompok dengan tujuh perlakuan isolat bakteri endofit dari P. elephantotis (PE 5, PE 7, PE 24, PE 25, PE 30, dan PE 49) serta satu kontrol. Pengamatan serangan OPT dilakukan setiap minggu, sementara analisis aktivitas enzim pertahanan tanaman dilakukan pada umur 55 hari setelah tanam. Hasil penelitian menunjukkan bahwa isolat bakteri Bacillus cereus PE 5 mampu menurunkan kejadian penyakit moler (Fusarium oxysporum f.sp. cepae) secara signifikan pada tanaman bawang merah dibandingkan dengan kontrol, sehingga membuktikan kemampuannya dalam meningkatkan ketahanan tanaman. Isolat PE 5, PE 30, dan A. nosocomonalis PE 49 juga meningkatkan aktivitas enzim peroksidase yang berperan dalam penguatan dinding sel dan sintesis senyawa antimikroba, sehingga memperkuat respons pertahanan tanaman. Meskipun demikian, aplikasi isolat bakteri tidak berpengaruh nyata terhadap produksi fenol, yang diduga dipengaruhi oleh serangan hama S. exigua yang merata pada seluruh tanaman. Temuan ini mengindikasikan bahwa aplikasi PGPB, terutama isolat Bacillus cereus  PE 5, berpotensi meningkatkan ketahanan tanaman bawang merah.

Abstract

The study aimed to determine the effect of application Plant Growth-Promoting Rhizobacteria (PGPR). The research was carried out in the greenhouse dan laboratory of plant disease at the Brawijaya University Malang. The study was arranged in a Randomized Block Design which consisted of 8 treatments and 3 replications. The results showed that the single isolate treatment have the highest average incubation period of Helminthosporium turcicum, namely the single isolate of Bacillus subtilis and Pseudomonas fluorescens bacteria for 9 day. The treatment of the consortium of 3 bacteria, namely Bacillus subtilis+Pseudomonas fluorescens +UB19 (Pseudomonas sp). showed an excellent antagonistic activity in suppressing diseases caused by the fungus Helminthospororium turcicum. Pseudomonas sp. had the ability to increase the plants fresh weight but had no effect on the roots fresh weight.  However, the bacterial consortium (B. subtilis, P. fluorescens, and UB 19 (Pseudomonas sp.)) in sweet corn plant growth was indicated by the higher average yield of plant height, number and weight of roots compared to other treatments.
