Abstract

Hibiscus macrophyllus, an important tropical tree, has high economic potential, however there are the problems in seedling procurement, i.e. seed dormancy and seed-borne pathogen. The purpose of the research was to evaluate the effect of sodium bicarbonate and acetic acid on fungal colonization, seed germination, and seedling growth of H. macrophyllus. A completely randomized design was used to test the six treatments: untreated seed, soaking seeds in boiling water and left 24 hours, soaking in boiling water and left 24 hours followed by soaking in acetic acid 1% (15 minutes), soaking in boiling water and left 24 hours followed by soaking in sodium bicarbonate 5% (15 minutes), soaking in acetic acid 1% (15 minutes) followed by soaking in boiling water and left 24 hours, soaking in sodium bicarbonate 5% (15 minutes) followed by soaking in boiling water and left 24 hours. Soaking in sodium bicarbonate 5% (15 minutes) followed by soaking in boiling water and left 24 hours could significantly decrease the fungal colonization. Sodium bicarbonate 5% and acetic acid 1% treatments could not improve seed germination. The sodium bicarbonate treatment followed by soaking in boiling water increased the seedling diameter, leaf length, leaf wide, root length, and leaf number.

Abstract

Salah satu faktor pembatas dalam keberhasilan tanaman untuk tumbuh optimal yaitu adanya serangan hama dan penyakit. Identifikasi hama dan penyakit penting dilakukan karena berkaitan dengan teknik pengendalian. Tujuan penelitian ini adalah untuk mengetahui jenis hama dan penyakit yang menyerang bibit kranji (Pongamia pinnata) dan teknik pengendaliannya. Metode penelitian meliputi identifikasi jenis hama dan penyakit serta teknik pengendalian dengan menggunakan pestisida biologi dan kimia. Hasil penelitian menunjukan, hama yang menyerang bibit kranji antara lain belalang (Valanga nigricornis), ulat grayak (Spodoptera sp.), ulat jengkal (Hyposidra talaca) dan ulat penggulung (Syllepta sp.) sedangkan patogen yang menyebabkan penyakir hawar daun yaitu Phytophthora sp. Teknik pengendalian hama bibit kranji dengan menggunakan larutan ekstrak biji mahoni atau insektisida Bacillus thuringiensis sedangkan teknik pengendalian penyakit menggunakan larutan ekstrak biji mahoni, larutan ekstrak daun cengkeh atau benomil

Abstract

Gall rust disease caused by Uromycladium falcatarium fungus is one of sengon (Falcataria moluccana) diseases in the nursery and field.  The purpose of this study was determining the effect of seed sources and controller type against the resistance of sengon seedlings from infection of  Uromycladium falcatarium in the nursery. The research design used a factorial completely randomized design with two 2 factors i.e sources of the seed (A1 = seed from the endemic area of gall rust/Kediri; A2 = seed from non-endemic of gall rust/Cianjur) and the type of cotrollers (B1 = no treatment  l; B2 =  biological fertilizer of Plant Growth Promoting Rhizobacteria (PGPR) (5 g.l-1); B3 = Biofungicide (5 g.l-1); B4 = biofungicide of soursop leaf extract (10 g.l-1); B5 =mancozeb (2 g.l-1). Each treatment combination consisted of 10 seedlings repeated 4 times. The observation variables were the disease incidence and intensity, the number of teliospores and thickness of the epidermal cell wall. The results of the study showed that the interaction of seed sources and type of controller affected the number of teliospores and thickness of the epidermis. The lowest number of teliospores (6.48 teliospores) was found in seedlings from non endemic  gall rust areas with the controller of soursop leaf extract. The thickest epidermal cells (5.43 μ - 5.84 μ) were produced from seedlings from gall rust-free area with PGPR solution controller, soursop leaf extract and mancozeb. The disease intensity in seedlings originating from gall-free areas (3.5 percent) is lower than endemic areas (5.2 percent).  PGPR and mancozeb were effective to the infection of fungus because the disease incidence and  intensity were low after the 3rd control stage.

Abstract

Salah satu kendala di persemaian Ficus variegataL. (nyawai) adalah hama. Olehkarenaitu, identifikasihama, gejala serangan hama dan pengaruhnya terhadap pertumbuhan bibit merupakan aspek yang perlu diketahui untuk mengetahui teknik pengendalian yang tepat.Sebanyak 90 bibit digunakan sebagai sampel. Metode penelitian yaitu pengamatan gejala, persentase serangan, jenis hama dan pengaruhnya terhadap pertumbuhan bibit.Gejala serangan hama pada daun nyawai yaitu berupa terbentuknya gall.Serangga yang menyebabkan gall pada daun nyawai yaitu Pauropsylla sp.(Homoptera : Psyllidae).Hasil pengamatan menunjukkan serangan galldapat menghambat pertumbuhan bibit umur 6 bulan. Tinggi bibit yang sehat sebesar 39, 28 cm, terinfeksi ringan sebesar 32, 95 cm sedangkan terinfeksi berat sebesar 32,65 cm.

Abstract

The obstacles in a nursery are seedling death and un optimal growth of seedling. This study aims to determine the effect of immersion of seedling in mancozeb and media given Trichoderma sp. on the percentage of seedling survival and  seedling growth of red jabon (Anthocepalus macrophyllus). The design of experiment used was completely randomized design (CRD) with 2 factors ie root immersion with and without mancozeb, and seedling media of soil, soil: husk: compost, soil: husk: compost + Trichoderma sp. The results showed that seedling treatment with mancozeb and  media did not give significant differences in seedling survival, percentage of shoot-root ratio and the quality index. The seedling treatments without mancozeb and media of soil: husk: compost (1:1:1) plus Trichoderma sp. produced optimal diameter and biomass while for optimal height was achieved by treatment of mancozeb and media of soil: husk: compost (1:1:1) plus Trichoderma sp.

Abstract

The forest tree species that are widely grown to produce pulp and paper raw materials are Acacia spp. and Eucalyptus spp. One alternative species is binuang bini (Octomeles sumatrana) which can be developed for plantations. To maintain high seed viability, it is necessary to know the handling of seeds and control of seed-borne diseases during storage. The purpose of this study was to determine the method of the effective technique to control the seed-borne diseases of binuang bini during seed storage. The techniques for Seed disease kontrol methods in seed storage are carried out using chemical and natural fungicide. The results showed that the pure live seed was influenced by a single factor of fungicide and storage room, interactions between fungicides and storage room, interactions between fungicides and storage periods as well as interactions between fungicides and storage space and storage periods. Seed handling of binuang bini can be conducted effectively and efficiently by storing the seed in refrigerator for 3 months without using fungicides, but it will be better if the seed is given benomil fungicide and stored in airconditioned room (temperature of 18℃-20℃ and relative humidity of 50%-60 %).

Abstract

Fungi are one of the main causes of damage to seeds. Fungi can be a pathogen or saprophyte such as Aspergillus sp. and Fusarium sp. The purpose of this study was to determine the effects of filtrate fungus Aspergillus sp and Fusarium sp on seed viability and seedling growth performance of Sengon (Paraserianthes falcataria). The experiment design used was the Completely Randomized Design (CRD), with treatment: control, filtrate of Aspergillus sp and Fusarium sp filtrate. Each treatment was repeated 4 times. Variables measured include germination, percent of live seed, height, diameters, biomass, root shoot ratio, and the index quality seeds. The results showed that the fungus Aspergillus sp filtrate and Fusarium sp significantly affect seed germination, life percent, height, diameter, NPA, IMB, and biomass of seedlings Sengon. The filtrate of fungus Aspergillus sp and Fusarium sp may cause the decrease in seed viability and seedling vigor of Sengon
