Abstract

ABSTRAK. Regenerasi tanaman bawang putih dapat dilakukan menggunakan kalus sebagai bahan. Namun metodeini dapat juga digunakan untuk perbanyakan, terutama pada produksi tanaman bebas virus. Tujuan penelitian ialahmemperoleh komposisi media yang sesuai untuk pertumbuhan kalus dan regenerasi beberapa klon bawang putih.Penelitian dilakukan di Laboratorium Kultur Jaringan Balai Penelitian Tanaman Jeruk dan Buah Subtropika mulaiMaret 2005 sampai dengan Agustus 2006. Rancangan yang digunakan adalah acak lengkap faktorial dengan 2perlakuan dan 6 ulangan. Induksi kalus dilakukan pada segmen apikal akar bawang putih yang ditanam secara invitro. Persentase jumlah eksplan yang berkalus cukup tinggi, berkisar antara 70-100% pada media MS+0,2 g/l CH +1 ppm 2.4 D maupun media MS + 1 ppm 2.4 D + 0,1 ppm IAA. Meskipun demikian, hanya 2 klon yang memberikanrespons pertumbuhan dan regenerasi kalus yang lebih baik dibandingkan klon lainnya, yaitu Lumbu Kuning danTawangmangu. Pada fase regenerasi menggunakan media MS + 1 ppm kinetin dan MS + 1 ppm IAA + 10 ppm 2-ip,kalus embrionik dari 2 klon tersebut menghasilkan persentase akar yang paling tinggi, masing-masing sebesar 60dan 70% dengan kisaran jumlah akar/eksplan mencapai 2-6 buah. Jumlah planlet berkisar antara 5-10 buah. Padafase perkembangan selanjutnya umbi mikro terbentuk sempurna.ABSTRACT. Devy, N.F. and Hardiyanto. 2009. Regeneration Capacity of Callus-derived from Root Segmentsof Several Local Garlic Clones. The regeneration of garlic using callus as explants is usually used for breedingprogram such as genetic transformation activities. However, this method can also be used as propagation method,especially for virus-free planting maerials. The experiment was carried out at Tissue Culture Laboratory, IndonesianCitrus and Subtropical Fruit Research Institute from March 2005 to August 2006. The experiment was arranged ina factorial randomized complete design with 2 treatments and 6 replications. The callus induction was derived fromgarlic apical root segment via in vitro. The percentage of total explants that produce callus was very high (70-100%)on both medium MS+0.2 g/l CH + 1 ppm 2,4 D and MS + 1 ppm 2, 4 D + 0.1 ppm IAA. Nevertheless, it was only2 clones that gave better callus growth and regeneration responses than others, these were Lumbu Kuning andTawangmangu. On the subculture medium (MS + 1 ppm kinetin and MS + 1 ppm IAA + 10 ppm 2-ip), the percentageof rooted embryogenic callus of both Lumbu Kuning and Tawangmangu were also high, i.e. 60 and 70% respectivelywith 2-6 roots/explant. Shoots grew as a mass, with total shoots number of 5-10 per a mass. Normal micro bulbletswere produced in the next development phase

Tujuan penelitianadalah mengetahui tipe seks yang terjadi akibat pengaruh perlakuan pemotongan akar dan umur bibit pada pepaya.Penelitian dilaksanakan di Probolinggo, Jawa Timur, pada bulan April sampai dengan Desember 2001. Penelitianmenggunakan rancangan petak terpisah dengan 4 ulangan. Petak utama adalah varietas yang dikombinasikan denganumur bibit, dan anak petak adalah akar yang tidak dipotong dan dipotong. Hasil penelitian menunjukkan bahwaperlakuan pemotongan akar tidak berpengaruh nyata terhadap persentase hidup dan persentase tanaman berbunga.Umur bibit tidak berpengaruh nyata terhadap persentase hidup, tetapi berpengaruh nyata terhadap persentaseberbunga. Pemotongan akar mempengaruhi persentase tanaman sempurna dan persentase tanaman betina, tetapi tidakberpengaruh nyata terhadap persentase tanaman berbunga jantan. Untuk meningkatkan persentase tanaman sempurnapada varietas Dampit, bibit ditanam pada umur 3 minggu setelah di polibag. Pemotongan akar pada varietas Sarironaumur bibit 3 minggu dalam polibag menyebabkan penurunan persentase tanaman betina secara nyata. Persentasetanaman sempurna pada varietas Dampit berbeda nyata dengan varietas Sarirona.ABSTRACT. Triatminingsih. R. 2009. The Effects of Root Cutting and Seedling Age on the Growth and SexType of Papaya. Out crossing the plant produces population segregation with variation of sex types in differentproportion. In plant crossing, identity of variety is the main key. On the other hand, sex identification technique atearly seedling stage is needed in order to accelerate generation cycle and to increase efficiency on crossing assessment.The objective of this research was to determine the influence of root cutting and seedling age on the growth and sextype of papaya. The research was conducted in Probolinggo, East Java, from April to December 2001. The split plotdesign with 4 replications was used in this experiment, where combination of variety and seedling age as the mainplot, and root cutting as the subplot. The results of this experiment showed that root cutting did not significantly affectthe percentage of survival and the flowering plant. Seedling age significantly affected the percentage of floweringplant, but not on the percentage of survival. Root cutting at seedling stage could affect the percentage of femaleflower and hermaphrodite flower. Root cutting on papaya seedling Sarirona variety at 3 weeks after transplantingin the polybag could decrease the percentage of female flower. While Dampit variety transplanted after 3-week inthe polybag without root cutting gave higher percentage of hermaphrodite flower. The percentage of hermaphroditeflower on Dampit variety was significantly different from Sarirona variety.

Abstract

ABSTRAK. Penelitian dilakukan di lahan petani di daerah Kabupaten Lebak, Banten. Jenis tanah Ultisol dengankandungan P rendah dan karakteristik fisik yang buruk. Tujuan percobaan adalah mempelajari pengaruh inokulasicendawan mikoriza arbuskula, penyediaan bahan organik dari pupuk kandang domba, dan dosis fosfat alam terhadapserapan P oleh tanaman, hasil mentimun, dan kandungan hara tanah masam Ultisols. Penelitian dilaksanakan daribulan Juli sampai Oktober 2004. Perlakuan terdiri atas 3 dosis fosfat alam, pupuk kandang domba, dan inokulasimikoriza. Kombinasi perlakuan seluruhnya ada 12 dengan 3 ulangan yang disusun dalam rancangan acak kelompokfaktorial. Hasil percobaan menunjukkan bahwa pemberian pupuk kandang domba meningkatkan efisiensi penggunaanfosfat alam, bobot buah, dan serapan hara. Interaksi antara mikoriza dengan pupuk P dan bahan organik denganpupuk P berpengaruh nyata terhadap serapan P. Tanpa pupuk kandang domba maupun tanpa mikoriza, dosis P yangdibutuhkan untuk menghasilkan buah mentimun adalah 200 kg P2O5 /ha, sedangkan dengan pupuk kandang dombamaupun dengan mikoriza dosis P yang dibutuhkan untuk menghasilkan buah mentimun yang sama hanya 100 kgP2O5 /ha dan kombinasi perlakuan tersebut meningkatkan ketersediaan P tanah. Inokulasi mikoriza tanpa bahanorganik menurunkan pH tanah. Penggunaan fosfat alam pada dosis tinggi dengan adanya bahan organik meningkatkansenyawa Ca-P pada tanah Ultisols. Teknologi yang diperoleh dari penelitian ini sangat berguna untuk pengembangantanaman sayuran pada tanah-tanah masam atau lahan marginal seperti Ultisols.ABSTRACT. Rosliani, R. , Y. Hilman, and N. Sumarni. 2009. The Effect of Rock Phosphate Fertilizer and SheepManure Application, and Arbuscular Mycorrhizae Fungi Inoculation on the Growth and Yield of Cucumberin Ultisol Acid Soil. The experiment was conducted at the farmer field in Lebak District of Banten Province. Thesoil was Ultisols with low available P and poor physical property. The objectives of this experiment was to study theeffect of rock phosphate and sheep manure application, and arbuscular mycorrhizae fungi inoculation on the growth,P uptake, and yield of cucumber in acid soil. The treatments consisted of 3 levels of rock phosphate, 2 levels of sheepmanure, and 2 levels of mycorrhizae inoculation. All treatment combinations were arranged in factorial randomizedblock design with 3 replications. The results showed that sheep manure supply could increased the efficiency ofrock phosphate application, growth, yield of cucumber, and nutrient uptake. The effect of mycorrhizae inoculationwas more clear when accompanied by sheep manure supply. Interaction of sheep manure and rock phosphate ormycorrhizae inoculation and rock phosphate significantly increased P uptake. Without sheep manure supply andwithout mycorrhizae inoculation, 200 kg P2O5/ha of rock phosphate was needed compare with sheep manure supplyand mycorrhizae inoculation, which only required 100 kg P2O5/ha of rock phosphate to reach the same productivity ofcucumber fruit, and these treatment combination P availability were also increased. Mycorrhizae inoculation withoutsheep manure could decrease the soil pH. Rock phosphate at high dosage with sheep manure could increase Ca-Pon Ultisols acid soil. The results of the experiment could be benefit for the development of vegetables on acid soilsor marginal land such as Ultisols.

Pada tanaman jeruk manis, pengaruh senyawalimonen dan linalool memberikan nilai adjusted r square yang tinggi, yaitu 0,943 dengan persamaan regresi Y=218,829 - 2,412 X1+ 5,987 X2 (X1=limonen, X2=linalool). Senyawa limonen memberikan efek negatif, sedangkanlinalool memberikan efek positif terhadap P. citri. Pada tanaman jeruk besar, populasi P. citri rendah dan konstandengan kandungan limonen tinggi dan kandungan linalool rendah sehingga efek negatif limonen terhadap P. citrilebih dominan. Hasil penelitian ini dapat memberikan alternatif pengembangan teknologi pengendalian tungau P.citri pada tanaman jeruk melalui manipulasi kandungan metabolit sekunder dalam tanamanABSTRACT. Istianto, M. 2009. Relationship Between Population Dynamic of Panonychus citri and VolatileCompounds on Sweet Orange and Pummelo Fruit. Panonychus citri is one of the important citrus pests in Indonesia.One of the key success for controlling the population of this pest is understanding the relationship between this miteand its host. Previous study showed that limonene and linalool influenced the biology and reproductive capacity of P.citri. The objectives of this research were to understand the relationship between population dynamic of P. citri andfluctuation content of dominant volatile compounds on sweet orange and pummelo. The research was conducted onpummelo orchard in Indonesian Citrus and Subtropical Fruit Research Institute, and sweet orange orchard in KusumaAgrowisata Batu Malang from April to September 2004. Observation was carried out to find out the dynamic of P.citri population and the content of dominant volatile compounds of sweet orange and pummelo. The data obtainedwere analyzed with multiple regression. The results showed that limonene and linalool have highly influence onpopulation dynamic of P. citri. On sweet orange, the effect of limonene and linalool indicated high value at adjustedr square with value of 0.943 with regression equation Y= 218,829 - 2,412 X1+ 5,987 X2 (X1=limonene, X2= linalool).Limonene showed negative effect while linalool showed positive effect to P. citri population. Population of P. citriwas lower and steady on pummelo with higher content of limonene and lower content of linalool, so that negativeeffects of limonene to P. citri were more dominant. These results give an alternative technologies to control P. citripopulation by manipulating secondary metabolite content inside the plant.
