PEMULIAAN KETAHANAN TANAMAN WIJEN TERHADAP PENYAKIT BUSUK PANGKAL BATANG (Phytophthora sp.)
Full text linkOne of the obstacles in the sesame plant breeding is a disease. Often to the detriment of potential disease is stem root symptoms and causative pathogen is the fungus Phytophthora sp. Losses caused by these pathogens can reach 50%, as it includes a soil borne disease and can cause a fall in the seed sprouts, thus potentially causing harm. The challenge remains to this day breeding research sesame resistance to Phytophthora sp. conducted in Indonesia and abroad is still very little. Until now, Phytophthora species on sesame plants yet further determination. Testing of the phytoalexin in sesame plants as active resistance mecanism sesame plant has not been done in depth, as well as the action of the sesame plant resistance genes against Phytophthora has not been much discussed

No full text<p>The local Madura maize variety planted on drought stress area suffered retarded plant growth and reduced grain yield. Research was conducted to alleviate the stress on crop plants, to survive under drought condition. The aim of this study was to investigate the effects of MVA and ALA on the growth of Guluk-guluk local maize variety planted under difference drought stresess. The experiment was conducted using split-split plot design with three factors in six replications. The first factor was variation of MVA application, i.e., without inoculation (M0) and with inoculation of mycorrhiza (M1). The second factor was ALA treatment which consisted of 3 levels, namely 0% (P0), 0.05% (P1) and 0.1% (P2). Third factor was plant watering intensity, i.e., watered once every 2 days (K0), watered once every 4 days (K1) and watered once every 6 days (K2) reaching field capacity, respectively. Data were analyzed by two-way ANOVA and Duncan’s Multiple Range Test (DMRT). The results suggested that MVA and ALA treatments gave significant effects in increasing the percentage of mycorrhiza infection, total leaf P content, total chlorophyll content, plant height, fresh and dry weight of shoot and root and shoot/root ratio. It showed a significant effect in decreasing ABA content in maize plant subjected to drought stress. The ABA content was 1.7 ppm in plants watered once every 2 days, where control plant had ABA content of 5.8 ppm. The best treatment was found on plants treated with mycorrhiza inoculation and 0.05% ALA and watered once every 4 days.</p></jats:p

Pengaruh Infeksi Cucumber Mosaic Virus (CMV) Terhadap Morfologi, Anatomi, Dan Kadar Klorofil Daun Tembakau Cerutu
Full text linkPenyakit virus pada tembakau cerutu menyebabkan kerugian yang cukup besar, yaitu dapat mengurangi produksi sekitar 7–30%. Secara morfologi, daun tembakau yang terserang virus pada umumnya menunjuk-kan gejala mosaik, berkerut atau menggulung, ukurannya menjadi lebih kecil, rapuh, elastisitas dan daya bakarnya menurun. Informasi tentang Cucumber Mosaic Virus (CMV) dalam bidang anatomi dan fisiologi ma-sih sangat sedikit, sehingga penelitian ini bertujuan untuk menambah informasi tentang pengaruh infeksi CMV terhadap karakter morfologi, anatomi dan fisiologi daun tembakau cerutu. Penelitian dilakukan pada bulan Agustus-November 2011, di Kebun Percobaan Karangploso dan Laboratorium Fitopatologi Balittas, Ma-lang, menggunakan rancangan acak kelompok dengan 3 ulangan. Inokulum CMV diambil dari tanaman sakit di lapang dan diperbanyak pada tanaman indikator. Inokulasi dilakukan pada tanaman tembakau cerutu varietas H-382 menggunakan sprayer duco type Sagola pada tekanan kompresor 4,5 kg/cm2. Pengamatan dilakukan pada 3 bulan setelah tanam terhadap parameter morfologi, anatomi tanaman dan kadar klorofil daun tembakau pada skor 0–5. Hasil pengamatan menunjukkan bahwa terdapat perbedaan yang signifikan antara tanaman yang sehat dengan tanaman yang diinfeksi CMV. Makin tinggi tingkat infeksinya, makin besar penurunan luas daun dan kadar klorofil total tanaman tembakau. Penurunan rasio klorofil a/b daun lebih tinggi pada skor 4 dibandingkan skor 5, yaitu sebesar 74%, tetapi kerusakan morfologi paling parah terjadi pada skor 5, dimana terjadi Perubahan bentuk dan secara anatomi terdapat bentukan kranz (spot-spot hitam) pada berkas pembuluh. Virus disease on cigar tobacco causes significant losses on yield, due to reduction on productivity 7–30%. Morphologicaly, tobacco leaf infected by virus generally shows symptoms of mosaic, wrinkled or curled, its size becomes smaller, fragile, elasticity, and burn down. Information about cucumber mosaic virus (CMV) in anatomy and physiology was still slightly, so objective of this study was to determine the effect of cucumber mosaic virus (CMV) infection to the character of the morphology, anatomy, and physiology of cigar tobacco leaves. The experiment was conducted in August–November 2011, at the Karangploso Experimental Station and Phytopathology Laboratory of ISFCRI, Malang, using a randomized block design with three replications. CMV was inoculated from diseased plants in the field and propagated on indicator plants. Inoculation was done on cigar tobacco H-382 varieties employing Sagola duco sprayer at a pressure of 4.5 kg/cm2 compressor. Observations were made at 3 months after planting for identifiying morphological and physiological parameters and leaf chlorophyl content of tobacco using score under 0–5. The results showed that there were significant differences between healthy plants and plants infected with CMV. The reduction in leaf area and total chlorophyl content of tobacco plants were greater as the rate of infection was higher.Decreasing in the ratio of chlorophyl a/b leaves was higher on plant with the score index of 4 than the score of 5 by 74%, but the most severe morphological damage occurs in plant with score of 5, indicating by change of shape and kranz formations (black spots) on the vascular bundle

Treatment of Hormax Growth Regulating Substances on Early Germination and Growth of Sugarcane (Saccharum Officinarum L.)
Full text linkThe average production of sugar is 2.26 million tons per year, while consumption is about 5.10 million tons per year. This is what causes the number of production and consumption of sugar shows a fairly high gap. Extensification approach in increasing sugar cane production to achieve sugar self sufficiency target is quite difficult to achieve, so intensification program is one of the efforts that can be done through evaluation and optimization phase of germination and plant growth with application of growth regulator (Fitohormon). If this is done then to obtain a sugar cane plant that has the productivity and optimal yield is likely to be achieved (Ahmad Khuluq and Ruly Hamida, 2014). The experiment was conducted at Experimental Garden of Agriculture Faculty, Merdeka University, April-June 2017. Using Randomized Block Design with 3 replications. and 8 doses of Hormax growing growth regulator, among others: 0 ml/l water (Control); 1 ml/l water; 2 ml/l water; 3 ml/l water; 4 ml/l water; 5 ml/l water; 6 ml/l water; 7 ml/l water. In conclusion, the use of Hormax significantly affected the germination rate, the number of leaves, the number of roots, the wet weight and the dry weight per cane plant. Increased dose of Hormax followed by an increase in all variables of sugar cane observation. The highest results were shown dose of Hormax 7 ml/l water), but statistically not significantly different from the treatment dose of Hormax 6 ml/l water) and dose of Hormax 5 ml/l water. It is recommended that to assist the germination and early growth of sugar cane using a dose of Hormax 5 ml/l water
