Abstract

To improve yield and cup quality, mature coffee tree as rootstock could be grafted with scion of selected genotype. This research aimed to study growth performance of mature trees resulted from intra and inter-specific grafting on Robusta coffee. The research was arranged in Randomized Complete Block Design with 3 replications. There were 12 treatments of entrees/under-stump genotype for coffee grafting including 8 treatments of intraspecific local Robusta/Robusta grafting and 4 treatments of interspecific coffee grafting of Robusta/Liberica and Arabica/Robusta. The results showed that intraspecific grafting of Robusta/Robusta, Robusta/Liberica, and Arabica/Robusta resulted in grafting mortality of 9.8%, 10.9%, and 24.8%, respectively. Until 28 weeks after grafting, branch growth variables were significantly affected by scion/rootstock of Robusta/Robusta, Robusta/Liberica, and Arabica/Robusta grafting. Grafted Arabica/Robusta coffee showed the poor growth performance. In second year of Robusta/Robusta and Robusta/Liberica growth, generative growth of cherry inflorescence per branch and number of cherries per inflorescence were not affected by scion and rootstock genotypes. Leaf and branch growth were very important variables correlating with other variables.

Abstract

Infestation of major pests and diseases on various cassava clones in Lampung-Indonesia. Lampung Province is one ofcassava producers in Indonesia which contributes more than 30% to the total national cassava production. However, theinfestation of pests and diseases can limit cassava production in the field. The objective of this research was to observe theinfestation level of major plant pests and diseases of cassava in Lampung. A survey was conducted in August 2016 in severallocations of cassava fields owned by farmers and experimental plots in the area of Faculty of Agriculture, University ofLampung. The results showed that cassava mealybug (Phenacoccus manihoti), papaya mealybug (Paracoccus marginatus)and red mite (Tetranychus urticae) infested at cassava clones in Lampung. The infestation of red mite tended to be higher thanthat of mealybugs. The cassava brown leaf spot disease that infested in mild to moderate severity was found on all cassavaclones, while viral disease with prevalence of 78% was only found on Duwet 1 clone in experimental plot.

Abstract

The objective of this study was to evaluate the effect of the application of Metalaksil-M on the disease incidence of downy mildew (Peronosclerospora maydis) and the yield of early-maturing corn genotype LL/TT-1. The experiment was arranged in randomized complete block design with three replications. Treatments consisted of Metalaxyll-M (300 ml in 1000 ml water) applied to the seeds (soaked for 1 minute), applied by spraying to the plants 7 days after planting, and the control. The results showed that the genotype LL/TT-1 was not resistant to downy mildew. The dry weight of ear and seeds per 12 plants harvested from plants were 70 and 72% higher than those of control respectively. The dry weight of ear and seeds per 12 plants harvested from plants sprayed with Metalaxil-M were also significantly higher than those of control.Key words: Peronosclerospora maydis, metalaxyl, seed treatment, Zea mays L.

Abstract

The objective of this study was to evaluate the effect of pre-germination treatment (physical and chemical) on the percentage and rate of germination of the f1 true seed of cassava derived from female parent UJ 3. The study consisted of two experiment, i.e., Experiment I and II. The pre-germination treatments for the two units experiment were the same, i.e., scarification of seed coat using sand paper, seed coat puncture, submerging the seed in one of the following liquid: the solution of H 2SO4 0,001M for 5 minutes, solution of H2SO4 0,001M for 10 minutes, solution of KNO3 3% for 48 hours, and water for 48 hours. The treatments were also compared to control. After being treated, the seeds were germinated on moistened paper (UKDdp) for Experiment I and on the soil medium in polybag for Experiment II. The two units of experiment were arranged in randomized block design with three replications. Soil medium consisted of mixture of soil and compost (1:1). The results showed that percentage and the rate of germination of the treatment of submerging seed of H2SO4 0,001M for 5 minutes followed by germination on soil medium were high. The percentage and the rate of germination for the treatment were 96%; 10,5% per day respectively; whereas for the control were 78,7% dan 6,8% per day. Scarification using sand paper indicated the percentage and rate of germination were high. It can be concluded that pre-germination treatment by submerging on H2SO4 0,001M for 5 minutes was suitable for germinating true seeds of cassava cv. UJ 3. Key words: Dormancy, pre-germination, Manihot esculenta Crantz, scarification, seed viability

Abstract

An efficient procedure of genetic transformation ultimately can accelerate the process of cultivar development of maize.  The objective of this study was to evaluate the effect of L-cysteine added to co-cultivation medium on the efficiency of Agrobacterium-mediated transformation of two genotypes of maize.  Explants of immature embryos were isolated from immature ears genotypes Hi-II and Tom Thumb harvested 11-13 days after pollination.  Then explants were inoculated with Agrobacterium strain C58C1 carrying pPTN345 vector and cultured in co-cultivation medium for 2 days then on delay medium for 14 days, on selection medium for 4 x 14 days, on regeneration medium, and finally on germination medium.  Co-cultivation media contained either 0 or 100 mg/L L-cysteine.  Based on assay at 2 days after inoculation,the transient expression of GUS at scutelar side of explants co-cultivated on medium containing 100 mg/L cysteine was higher than that of the control (0 mg/L cysteine).  Transient expression of GUS on the explants of Tom Thumb was higher than that of Hi-II.  However, transgenic plants in this study were only produced from Hi-II explants co-cultivated in a medium amended with 100 mg/L L-cysteine. No transgenic plants was produced from explants of Tom Thumb due to low efficiency of induction of embriogenic calli.  The efficiency of transformation using explants of Hi-II cocultivated in a medium amended with 100 mg/L L-cysteine was 4 independent transformants or transgenic plants out of 70 explants inoculated or 5.7%.    Key words:  Agrobacterium tumefaciens, corn, L-cysteine, Hi-II, Tom Thumb

Abstract

Selain sebagai bahan pangan dan pakan, sorgum berpotensi menghasilkan nira untuk bioethanol. Beragamnya potensi hasil nira, mendorong perlunya evaluasi keragaan berbagai genotip sorgum untuk digunakan sebagai kriteria seleksi. Penelitian ini bertujuan untuk mengevaluasi produksi nira, membandingkan keragaman genetik dan fenotip pada beberapa genotip sorgum, serta menghitung heritabilitas arti luas. Penelitian dilaksanakan di Desa Sukanegara, Kecamatan Tanjung Bintang, Kabupaten Lampung Selatan dari April 2017 sampai Februari 2018.  Rancangan perlakuan disusun secara strip plot dalam Rancangan Acak Kelompok Lengkap dengan tiga ulangan yang digunakan sebagai kelompok.  Kondisi tumpangsari dan monokultur yang digunakan sebagai pembanding disusun secara strip plot. Sebanyak 15 genotip digunakan, yaitu GH 3, GH 4, GH 5, GH 6, GH 7, GH 13, Super 1, Super 2, Samurai 1, UPCA, Numbu, Mandau, Talaga Bodas, P/IWHP, dan P/F 5-193-C. Hasil penelitian menunjukkan bahwa genotip Talaga Bodas mempunyai kandungan nira yang cukup tinggi baik pada kondisi tumpangsari maupun monokultur yang masing-masing sebesar 144,0 ml dan 166,0 ml.  Sementara genotip Super 1 menunjukkan kandungan nira paling tinggi pada kondisi tumpangsari (163,0 ml) dan genotip GH13 menghasilkan volume nira paling tinggi pada sistem monokultur (183,0 ml). Nilai heritabilitas arti luas pada tinggi tanaman, nilai brix, kandungan nira, dan jumlah ruas pada sistem tanam tumpangsari dan monokultur termasuk dalam kriteria tinggi (0,6-0,9). Nilai heritabilitas yang tinggi pada karakter tersebut menunjukkan bahwa faktor genetik lebih berpengaruh sehingga bisa digunakan sebagai kriteria seleksi.ABSTRACT In addition to foodstuffs and feed, sorghum potentially produces “nira” for bioethanol. The varying potency of the nira results, prompting the need to evaluate the performance of various sorghum genotypes for use as selection criteria. The objectives of this study were to evaluate nira production, to compare genetics and phenotype variances of sorghum genotypes, also to calculate broad sense heritability of some sorghum genotypes.  This study was conducted at Desa Sukanegara, Kecamatan Tanjung Bintang, Kabupaten Lampung Selatan from April 2017 to February 2018.  The experiment was designed by stripe plot in completely randomized block design with three replications used as block. The conditions of monoculture and intercropping used as comparison were arranged in stripe plot.  As many as 15 genotypes used in this study i.e. GH 3, GH 4, GH 5, GH 6, GH 7, GH 13, Super 1, Super 2, Samurai 1, UPCA, Numbu, Mandau, Talaga Bodas, P/IWHP, and P/F 5-193-C. The result showed that Talaga Bodas genotype had high volume of nira content under monoculture and intercropping conditions as 144.0 ml and 166.0 ml, respectively. However, Super 1 genotype had high nira content (163.0 ml) under intercropping condition and GH13 genotype had high nira content under monoculture (183.0 ml). Broad sense heritability of plant height, brix value, nira content, and internode number in both intercropping and monoculture conditions was high (0.60 – 0.90).  These high heritability values mean that these characters are influenced by genetics factor and could be used as selection criteria.
