Abstract

Response of some patchouli clones (Pogostemon cablin Benth.) to burrowing nematode (Radopholus similis Cobb.)One of the seious poblems on patchouli is infection of plant parasitic nematode. Nine clones of Aceh patchouli (Pogostemon cablin Benth.) namely KJ (oiginated from tissue cultue) Meulaboh-2, Sidikalang, Lhokseumawe-2, Cisaroni . Cirateun, Tapak Tuan. Aceh Merah. Situak-2, and one clone of Java patchouli (P. heyneanus Benth.) namely Giilaya, were tested to infection of buowing nematode (Radopholus similis Cobb.) in the glasshouse of Research Institute for Spice and Medicinal Crops, Bogor fom July to November 1997. Each clone was inoculated with 500 of R. similis. An expeiment have been conducted to know the esponse of some patchouli cultivars against nematode. The expeiment was arranged in a Completely Randomized Design with thee replicates. The esults showed that the infection of R. similis reduced root weight greater than that of shoot weight, the colour of leaf became reddish or dark purple. Based on the development rate of nematode and level of damage, Giilaya appeared to be resistant, whereas Sidikalang, Cisaroni and Situak-2 clones wee slightly susceptible. KJ. Lhokseumawe-2, Cirateun. Tapak Tuan and Aceh Merah clones were susceptible, whereas Meulaboh-2 were highly susceptible against R. similis. Characteistic of Java clone that esistance and Aceh clone that shyhtly susceptible to R. similis may be useful for providing new vaieties with high content of oil and resistant to nematode.

Abstract

Nematoda parasit merupakan salah satu jenis organisme pengganggu tumbuhan (OPT) penting yang menyerang berbagai jenis tanaman utama di Indonesia dan Negara-negara tropis lainnya dan kerugian yang diimbulkannya dapat mencapai 25% dari potensi produksi. Baktei Pasteuria penetrans adalah salah satu agensia hayati yang sangat potensial untuk pengendalian biologi nematoda parasit tanaman. Bakteri ini tersebar luas di seluruh dunia dan dapat memarasit 205 spesies nematoda. Kendala utama dalam perbanyakan bakteri ini adalah belum dapat diperbanyak pada media buatan, sehingga perbanyakannya dilakukan secara konvensional pada tanaman tomat di lapang, yaitu dengan cara menggunakan akar tanaman tomat yang sudah terserang nematoda terinfeksi bakteri tersebut. Patogenisitas baktei akan meningkat pada kondisi lingkungan dengan suhu 30°C, pH tanah 6,7 dan kelembaban tanah 60%. Penggunaan P. penetrans dalam mengendalikan nematoda akan lebih berhasil apabila dikombinasikan dengan bahan organik seperti pupuk kandang sapi, ayam dan abu sekam. Daya infeksi seiap isolat P. penetrans berbeda-beda. Uji di laboratorium, rumah kaca dan lapang menunjukkan bahwa P. penetrans dapat menginfeksi dan menekan populasi Meloidogyne spp sebesar 57-100%. Pada tanaman jahe, P. penetrans dapat menekan populasi M. incognita (sebesar 93,85%) dan Radopholus similis serta meningkatkan berat impang jahe sebesar 16,11-54,06%; sedangkan pada tanaman lada dapat menekan populasi M. incognita sebesar 49,68 -94,02% dan R. similis sebesar 68,89 -93,33% serta mengurangi penyakit kuning sampai 26,67 - 50%. Pada tanaman nilam, P. penetrans menekan populasi Pratylenchus brachyurus sebesar 43 - 82% dan meningkatkan berat basah sebesar 57-71%.
