Abstract

Bangun - bangun [Plectranthus amboinicus (Lour.) Spreng] merupakan salah satu jenis sayuran fungsional yang berfungsi sebagai Laktagogum. Bangun-bangun juga mempunyai kandungan antosianin yang berkhasiat sebagai antioksidan. Percobaan ini dilakukan di Kebun Percobaan IPB Leuwikopo, Kec. Darmaga, Bogor, dari bulan September 2012 hingga Februari 2013 untuk mempelajari respon pertumbuhan dan fisiologis Plectranthus amboinicuspada perbedaan tingkat naungan. Penelitian ini menggunakan rancangan acak kelompok faktor tunggal dengan 2 taraf perlakuan, yaitu tanpa naungan (N0) dan naungan (N1). Setiap perlakuan diulang tiga kali sehingga terdapat enam satuan percobaan. Hasil percobaan menunjukkan bahwa naungan menghasilkan daun bangun-bangun yang lebih lebar dan tipis dibandingkan tanpa naungan. Naungan menurunkan kandungan antosianin dan bobot basah pucuk per tanaman bangun-bangun, tetapi meningkatkan kandungan klorofil ?a? dan total klorofil dibandingkan tanpa naungan.Kata kunci: bangun-bangun, intensitas cahaya rendah, metabolit sekunder

Abstract

          The application of organic fertilizer and crop rotation are combination of cultivation system integrally to preserve land fertility. This study aimed to determine the effect of crop residues produced in the first season to reduce organic fertilizer rate for mustard greens cultivation in the second season. The experiment was conducted at IPB organic farm, Cikarawang, Darmaga in April until June 2015. The first season was the first experiment conducted separately for soybean and corn to study different manure types for both crops which the rate of each manure was 20 ton ha-1 for soybean and 25 ton ha-1 for corn. Soybean and corn residues were used in the following season on mustard green cultivation. The experimental design was split plot design with crop residues as main plot, and combination of manure types (chicken, cow, goat) and rates (0, 10 ton ha-1) as sub plot. Data were analyzed using variance. Means were statistically compared with Tukey test at ? < 0.05 level. The results showed that the soybean and corn residues can be used as nutrient sources for mustard greens cultivation. The application of manure was not necessary for mustard greens cultivation if soybean or corn residues were added in the second season and there was residues from manure in the first season.Keywords: chicken manure, cow manure, crop residue, goat manure

Abstract

ABSTRACTWaterleaf shoot (Talinum triangulare (Jacq.) Willd) is consumed as vegetable that contains some metabolites. The purpose of this research was to investigate the effect of organic fertilizer on shoot production and its metabolites i.e. protein, vitamin C, flavonoid, and peroxidase enzyme (POD) activity at 10, 12, and 14 weeks after planting. This experiment was conducted at Leuwikopo Experimental Station, Bogor, Indonesia from November 2012-February 2013. The organic fertilizers applied were cow manure (CM) (12.3 ton ha-1), rock phosphate (RP) (1.5 ton ha-1), and rice-hull ash (RH) (5.5 ton ha-1). These organic fertilizers were combined into four treatments by using minus one test method and one control. Each treatment was repeated three times. The result showed that combination of organic fertilizer had the same effects on shoot production and metabolite content of waterleaf. It showed that the amount of organic fertilizers was not significantly sufficient to contribute nutrients to the plant. Keywords: flavonoid, POD activity, repeated harvesting, Talinum triangulare, vitamin C

Abstract

ABSTRACTBangun-bangun [Plectranthus amboinicus] is a functional vegetable that is used as lactagogue. This research was aimed to provide information of the effect of organic fertilizer on shoot, total phenolic, and anthocyanin production of bangun-bangun. This experiment was conducted at Bogor Agricultural University, Leuwikopo experimental station (Indonesia), from December 2012 to February 2013. The experiment was laid out in randomized block design with single factor with five combination of organic fertilizer treatments (combination of cow manure 12.3 t ha-1, rock phosphate 1.5 t ha-1, rice-hull ash 5.5 t ha-1) with three replications. The result showed that application of organic fertilizer increased of shoot production. Application of 12.3 t ha-1 cow manure + 1.5 t ha-1 rock phosphate + 5.5 t ha-1 rice-hull ash produced shoot dry weight ha-1 (57.33%) and metabolite production ha-1 (total phenolic 12.06%, anthocyanin 41.73%) higher than no fertilizing (P > 0.05). Application of cow manure + rock phosphate produced the lowest shoot dry weight ha-1 and metabolite production ha-1. The result of this research suggested that nitrogen, phosphorus, and potassium were needed on shoot production of bangun-bangun.Key words: Plectranthus amboinicus, phenylalanine ammonia lyase, secondary metabolite

Abstract

The Effect of Water Management and Rice Genotypes to Against Toxicity of Iron and Productivity of Rice in Tidal Land Type B in South Sumatera. Tidal land is one of the alternative land to support increased productivity of rice, but rice productivity in this area is still low, and the land utilization is not optimal yet. One factor is high iron content in the soil that can be toxic to plants. The purposes of this study were (1) to determine the effect of water management and rice genotype, as well as their interaction on the percentage of leaf bronzing, growth and yield of rice in tidal lands, (2) to select an alternative combination of water management and rice genotypes that may increase rice yields in tidal land. This study was conducted from February until June 2013 in the tidal area with type B overflow, Mulia Sari village, Banyu Asin regency, South Sumatera. The experimental design used was a split plot design with three replications. The main plot was water management with four levels, while the subplot was rice genotypes consisted of three genotypes. The results showed that water management and its interactions with plant genotypes had significant effect only on the percentage of bronzing, Fe content in shoot, and Fe content in root crops, while the plant genotype significantly affected all observed variables. The use of genotypes tolerant to iron toxicity (Indragiri) combined with (form stagnant and saturated water management) drainage with intervals of two weeks could give yield 6.8 and 6.2 t/ha respectively.Keywords : Water management, genotype paddy, tidal landABSTRAKLahan pasang surut merupakan salah satu lahan alternatif untuk mendukung peningkatan produksi padi, tetapi produksi padi di lahan ini masih rendah, dan pemanfaatan lahannya belum optimal.

Abstract

Induction of polyploid gametes is one of useful plant polyploidization methods. Some of its benefits are to obtain triploid and tetraploid progenies at the same time by cross and self pollination. Previous research showed that some morphological characters which could be the indications of polyploidy plantlets before the analysis of chromosome number. Colchicine treatment on flower bud of diploid Phalaenopsis amabilis was conducted to determine the effect of colchicine on flower bud development, plantlets morphology and growth, and potential of polyploidy induction based on plantlets morphology. Colchicine concentrations in the experiment were 0, 50, 500, 1,000, and 2,000 mg L-1, with three days duration of treatments with aluminium foil wraps on flower buds. The results showed that high colchicine concentrations (2,000 mg L-1) inhibited flowers blooming of treated flower buds. Based on morphological characters, plantlets were classified into normal and putative polyploid plantlets. Putative polyploid plantlets from colchicine with the concentration of 50, 500, and 1,000 mg L-1 were 71.2, 86.4, and 100.0% respectively.Keywords: colchicine concentration, morphological characters, normal plantlets, putative polyploidy, reproductive organ
