Abstract

Planting of leguminous cover crops is a standard practise in preparing land for oil palm and rubber plantations. The synergism capability of Bradyrhizobium, Aeromonas punctata (phosphate solubilizing bacteria) and Acaulospora tuberculata (AM fungi) to increase growth of leguminous cover crops (Calopogonium caeruleum and Centrosema pubescens) was studied in a glass house experiment using polybag (10 x 10 cm) containing acid soil with low level nutrition of Ciomas, Bogor. Research results showed that Bradyrhizobium, A. punctata and A. tuberculata inoculation on C. caeruleum signifycantly enhanced plant height, and number of leaves. However, the treatment did not increase biomass and N, P, and K uptake of plant. Number of nodule were increase when the plant was inoculated with A. tuberculata alone or in combination with Bradyrhizobium and A. punctata. Centrosema pubescens gave good response when inoculated with A. tuberculata. However, dual inoculation of the two bacteria Bradyrhizobium and A. punctata with A. tuberculata signifycantly enhance plant height, plant biomass, N, P, and K plant uptake. AbstrakPenanaman tanaman kacang-kacangan penutup tanah merupakan standar dalam penyiapan lahan pada pengusahaan kelapa sawit dan karet. Kemampuan sinergisme Bradyrhizobium (bakteri penambat N2), Aeromonas punctata (bakteri pelarut fosfat), dan Acaulospora tuberculata (cendawan mikoriza arbuskula) untuk meningkatkan pertumbuhan tanaman kacangkacangan penutup tanah (Calopogonium caeruleum dan Centrosema pubescens) dipelajari dalam percobaan rumah kaca menggunakan polibag berukuran 10 x 10 cm berisi tanah Ciomas Bogor yang bereaksi masam dan miskin hara. Hasil penelitian menunjukkan bahwa inokulasi Bradyrhizobium, A. Punctata, dan A. tuberculata pada C. caeruleum nyata meningkatkan pertumbuhan tinggi tanaman dan jumlah daun. Namun, perlakuan ini tidak meningkatkan biomasa dan serapan N, P, dan K tanaman. Jumlah bintil akar meningkat pada tanaman yang diinokulasi A. tuberculata sendiri atau dalam kombinasinya dengan Bradyrhizobium dan A. punctata. Centrosema pubescens menunjukkan respon yang baik bila diinokulasi dengan A. tuberculata. Bagaimanapun juga inokulasi dua bakteri, yaitu Bradyrhizobium and A. punctata yang disertai A. tuberculata nyata meningkatkan tinggi tanaman, biomasa, serapan N, P, dan K tanaman.

Abstract

Field Selection on Several Rice Varieties for Resistance to Bacterial Leaf Blight strain IV and VIII. Bacterial leaf blight (BLB) on rice (Oryza sativa) caused by Xanthomonas oryzae pv. oryzae (Xoo) is the major obstruction for rice production. Powerful strategy to control BLB is generally conducted by planting resistant plant. Meanwhile, the main way to explore germplasm as the source of resistance gene is conducted by selection a wide rice varieties. Field selection for resistance to BLB on 150 rice-varieties (BB-Biogen collection) was conducted in 2009 in Cianjur. Three leaves and flag leaves of individual hills at vegetative and flowering stage were inoculated by clipping the leaf tip with scissors which had been connected with a suspension bottle of bacterial cells (109- 1010 cells/ml) of the isolates which represented bacterial groups (strain) IV and VIII, respectively. Each plant was inoculated with one race. Two weeks after inoculation, length of the lesion developed on the inoculated leaf was measured, as an index of severity of infection by BLB. This experiment was treated as Factorial-Randomized Completed Block Design (two factor-with 3 replications, respectively). The resistancyreaction to strain IV and VIII was observed as the variable tested, while the factors measured consists of plant-varieties and two bacterial strains. The results showed that 11 varieties with a resistance-reaction to Xoo strain IV, inwhich 5 varieties poses a consistent resistance-reaction, i.e: Pulu Bolong, Pelopor, Gombal, Barito and Kapuas. While resistancereaction to Xoo strain VIII obtained only one variety : IR42 (score-1), while 17 others showed intermediate resistancy (score-3). AbstrakPenyakit hawar daun bakteri (HDB) yang disebabkan oleh Xanthomonas oryzae pv. oryzae (Xoo) pada padi (Oryza sativa) merupakan faktor pembatas upaya peningkatan produksi padi. Pencarian gen-gen tahan terhadap HDB sangat diperlukan untuk pengendalian penyakit tersebut. Seleksi ketahanan terhadap HDB dilakukan di Cianjur pada MT 2009 terhadap 150 varietas padi koleksi Bank Gen, BB-Biogen. Isolat Xoo yang diuji adalah strain IV dan VIII. Inokulasi dilakukan dua kali, yaitu pada fase vegetatif dan generatif dengan cara menggunting 3-5 cm dari ujung daun dan daun bendera dengan gunting yang telah dihubungkan dengan botol berisi suspensi Xoo strain IV dan VIII (109-1010 sel/ml). Rancangan percobaan yang digunakan dalam penelitian ini adalah acak kelompok faktorial dengan tiga ulangan. Sebagai varietas pembanding tahan digunakan IRBB7 dan pembanding rentan varietas Kencana Bali. Reaksi ketahanan tertinggi terhadap Xoo strain IV ditunjukkan oleh 11 varietas terpilih dengan reaksi agak tahan, lima varietas di antaranya menunjukkan reaksi yang konsisten agak tahan, yaitu varietas Pulu Bolong, Pelopor, Gombal, Barito, dan Kapuas. Reaksi ‘tahan’ terhadap Xoo strain VIII ditunjukkan oleh satu varietas introduksi IR42. Untuk varietas terpilih dengan reaksi ‘agak tahan’ terdapat 17 varietas.

Abstract

The characterization of indian mulberry or noni (Morinda citrifolia L.) was conducted in some areas of Java in May to December 2003 to study their morfological and quality variations. It was found that there were seven distinct groups of noni types. Base on fruit size, there were two distinguished groups; types with big fruits (Types 1, 2, 4, and 5), and types with small fruits (types 3, 6, and 7). Big fruit had higher extract concentration than small fruit. Type 4 was seed less, had in highest juice percentage. The seed less type was rare and only found in Surakartya and Semarang in a limited population. The types widely grown throughout the entire survey areas. The type 5 has highest fruit weight, its fruits grew in cluster, it was found in Malingping and Tasikmalaya. Base on fruits taste, none could be grouped into two groups: fruits with sour-sweet taste and fruit with bitter taste. All types which grew near the beach had bitter taste. The bitter fruits did not fall when they were ripe, whereas the sour-sweet fruits fall at the some of ripening. AbstrakPenelitian dilakukan di sentra pertanaman mengkudu di Jawa Barat (Ciampea, Cipaku, Jasinga, Tasikmalaya), Banten (tepi pantai Malingping), Jawa Tengah (Surakarta, Semarang, Yogyakarta), dan di Jawa Timur (Lamongan) pada bulan Mei- Desember 2003, untuk mengetahui ciri-ciri morfologi dan mutu buah mengkudu. Telah diperoleh tujuh tipe mengkudu dengan perbedaan sifat-sifat morfologi, fisiologi, dan mutu buahnya. Perbedaan tipe mengkudu yang mencolok adalah bentuk, ukuran, rasa, dan rendemen daging buah. Dari ketujuh tipe tersebut terdapat dua tipe yang berukuran buah besar (tipe 1, 2, 4, dan 5), dan tipe berukuran buah kecil (tipe 3, 6, dan 7). Tipe mengkudu yang ukuran buahnya besar, rendemen jus dan daging buahnya lebih tinggi dibandingkan dengan yang buahnya berukuran kecil. Dari tipe berukuran buah besar terdapat satu tipe berbiji sedikit yang dianggap seed less, yaitu tipe 4, sehingga rendemen daging buahnya tinggi. Tipe seed less termasuk langka, karena hanya ditemukan di Surakarta dan Semarang dengan populasi terbatas. Tipe yang mempunyai daerah penyebaran luas adalah tipe 1, ditemukan di tepi pantai hingga ketinggian 600 m dpl. Tipe 5 bobot buahnya paling tinggi, buah bercabang, ditemukan di Malingping dan Tasikmalaya. Rasa daging buah, dapat dibedakan menjadi dua kelompok, yaitu asam manis dan pahit. Semua tipe yang tumbuh di tepi pantai rasa buahnya pahit, dan setelah masak buahnya tidak langsung jatuh. Kelompok yang mempunyai rasa buah tidak pahit, buah tidak langsung jatuh setelah masak.
