Pribadi, Moh. Lambang (2017) Eksplorasi Jamur Patogen Pada Pembibitan Pinus (Pinus merkusii Jungh. et de Vriese) Di Kesatuan Pengelolaan Hutan Perum Perhutani Kabupaten Malang. Sarjana thesis, Universitas Brawijaya.
Abstract
Pinus merkusii Jungh. et de Vriese (Pinaceae) merupakan jenis pinus asli Indonesia. Saat ini permintaan getah pinus mengalami peningkatan baik di pasar lokal maupun internasional. Salah satu kendala dalam budidaya pinus di Indonesia adalah serangan patogen di pembibitan. Salah satu perkebunan yang mengalami kendala tersebut yaitu KPH Perum Perhutani Kabupaten Malang. Penelitian bertujuan mengidentifikasi jamur patogen yang menyerang pada pembibitan pinus di KPH Perum Perhutani Malang. Diharapkan penelitian dapat memberikan informasi mengenai jenis jamur patogen yang menyerang bibit pinus khususnya di KPH Perum Perhutani Kabupaten Malang sehingga dapat digunakan sebagai dasar pengendalian jamur patogen pada pembibitan pinus. Penelitian dilaksanakan di Laboratorium Penyakit Tumbuhan Fakultas Pertanian Universitas Brawijaya, Malang. Penelitian dilaksanakan pada Bulan November 2016 sampai Februari 2017. Isolasi jamur patogen di lakukan pada bibit pinus merkusi berumur 5 bulan. Sampel diambil dari lahan pembibitan pinus di KPH Perum Perhutani Malang. Jamur diisolasi dari rizosfer, akar, batang dan daun bibit pinus bergejala. Jamur yang diperoleh diidentifikasi secara makroskopis dan mikroskopis lalu dilakukan Postulat Koch menggunakan bibit pinus sehat berumur 1 bulan. Berdasarkan identifikasi diperoleh 14 jenis jamur dari 10 genus yaitu Acremonium, Penicillium, Fusarium, Rhizoctonia, Aspergillus, Rhizopus, Sclerotium, Pestalotia, Alternaria dan Curvularia. Seluruh isolat dibedakan berdasar kenampakan makroskopis dan mikroskopisnya. Berdasar hasil pengujian Postulat Koch pada semua isolat, hanya isolat dari genus Fusarium dan Pestalotia yang bersifat patogen pada bibit pinus. Gejala yang ditimbukan oleh Fusarium sp. yaitu busuk pangkal batang sedangkan gejala yang ditimbulkan oleh Pestalotia sp. berupa bercak daun yang dimulai dari daun muda.
English Abstract
Pinus merkusii Jungh. et de Vriese (Pinaceae) is native pine in Indonesia. Nowdays, demand for pine sap has increased in both local and international markets. One of the obstacles when conducting pine cultivation is pathogen attack during nurseries. One of the plantations that expirienced this problem is KPH Perum Perhutani Malang. The purpuse of this research was to identify of pathogenic fungi that attacked pine seeds. This research was expected could give information about what kind pathogenic fungi that attacked on pine nurseries especially in KPH Perum Perhutani Malang, so could get the basic information of controling pathogenic fungi. Ths research was conducted at Laboratory of Phyopathology Department of Pest and Disease Faculty of Agriculture Brawijaya University from November 2016 to February 2017. Exploration of pathogenic fungi was done on pine seeds by 5 months old, sample plants was taken from pine nursery land at KPH Perum Perhutani Malang. Fungi were isolated from rizosfer and symptomatic plants organ. The obtained fungi were identified and then tested for Postulat Koch by using 1 month old pine seeds. Based on the result of identificaton was obtained 14 types of fungi from 10 genus that were Acremonium, Penicillium, Fusarium, Rhizoctonia, Aspergillus, Rhizopus, Sclerotium, Pestalotia, Alternaria and Curvularia. All of them were differentied based on the appearance of macroskopic and microskopic morphology. After done Postulat Koch test to all fungi, only from Genus Fusarium and Pestalotia that could cause symptoms. Symptoms caused by Fusarium sp was stem rot and by Pestalotia sp. was leaf spot.
