Abstract

Pruning is one of the techniques to improve plant growth and production. The aim of this research was to determine the effect of pruning on vegetative and generative growth, and fruit quality of ‘Crystal’ guava. The experiment was conducted from September 2016 to April 2017 at Cikabayan Research Station of Bogor Agricultural University, Dramaga, Bogor, Indonesia (-6.550780, 106.714531). The experiment used completely randomized design with six replications. There were three treatments i.e. a) pruning by leaving 4 pairs of leaves, b) pruning by leaving 8 pairs of leaves, and c) control (without pruning). Pruning was applied after shoot leaves grew fully. The result showed that pruning significantly increased the total number of shoots and generative shoots. Pruned plants produced more flower and fruit than un-pruned ones. Pruning by leaving 4 pairs of leaves tended to produce higher number of flower and fruit than those by leaving 8 pairs of leaves. Fruit weight and internal fruit quality were not affected by pruning.

Abstract

Perkecambahan adalah suatu tahap kritis pada siklus hidup tanaman. Perbaikan toleransi pada tahap perkecambahan dapat meningkatkan stabilitas pertumbuhan dan produksi tanaman. Upaya untuk menekan pengaruh cekaman dapat dilakukan dengan teknik priming dan penambahan asam giberelat (GA). Sebagai tanaman introduksi, jintan hitam akan menghadapi banyak kendala dalam budidaya khususnya dari faktor lingkungan abiotik seperti iklim. Penelitian ini bertujuan untuk mengkaji pengaruh perlakuan hidropriming dan penambahan GA3 terhadap viabilitas benih jintan hitam. Penelitian dilaksanakan sejak November sampai Desember 2015 di Laboratorium Seed Storage & Seed Quality Testing, Departemen Agronomi dan Hortikultura, Fakultas Pertanian IPB. Bahan yang digunakan adalah benih jintan hitam aksesi Kuwait dan India. Rancangan penelitian yang digunakan Acak Kelompok Faktorial dengan tiga faktor yakni aksesi (India dan Kuwait), waktu hidropriming (0, 12, dan 24 jam) dan aplikasi GA3 (dengan dan tanpa GA3), tiga ulangan dengan 25 butir benih setiap satuan percobaan. Peubah yang diamati adalah daya berkecambah, indeks vigor, kecepatan tumbuh, panjang kecambah, panjang radikel, bobot basah kecambah. Hasil penelitian menunjukkan bahwa aplikasi GA3 akan efektif jika didahului dengan perlakuan hidropriming. Perlakuan hidropriming 12 jam yang diikuti aplikasi GA3 meningkatkan viabilitas benih jintan hitam aksesi Kuwait dan India melalui peningkatan daya berkecambah (27,00 dan 22,80%), panjang radikel (55,50 dan 60,20%), kecepatan tumbuh (36,00 dan 27,60%), dan indeks vigor (27,00 dan 22,80%).

Abstract

Moringa oleifera is universally known as the miracle plant or the tree of life. Moringa leaf extract contains phenolic acids and flavonoids, especially flavonols (quercetin, kaempferol, isorhamnetin glycosides) and flavones (apigenin). This study aimed to elucidate any correlations between nutrient, pigment, and flavonoid concentrations for different leaf positions and different growth phases. The results showed that pigment and total flavonoid concentrations increased from the 1st leaf to the 5th leaf, while nutrient concentration decreased. Pigment concentration, total flavonoid, and nutrient concentration were higher in the vegetative phase than the generative phase. The concentration of nutrients in the generative plants displayed a significant positive correlation with chlorophyll concentration. The 1st to 5th leaf of the vegetative plants can be used as indicator leaves for tissue analysis of the moringa plant.

Abstract

Five shallot varieties namely ‘Bauji’, ‘Bantaeng’, ‘Tuk Tuk’, ‘Rubaru’, and ‘Palasa’ were examined for their leaf pigment, total phenolic content, leaf tissue nutrient analysis, and green shallot production. The experiment was conducted in in Cikabayan greenhouse, IPB University, Dermaga, Bogor, arranged in a randomized complete block design with single factor (variety) and three replications. The observations were carried out three times in the maximum vegetative period, consisting of 20, 30, and 40 days after planting. The result showed that ‘Palasa’ had the highest leaf pigment content, such as chlorophyll a, chlorophyll b, total chlorophyll, and carotenoid, while the anthocyanin content fluctuated between the varieties and observation times. ‘Palasa’ also had the highest sulfur content in the leaf tissues. On the contrary, ‘Palasa’ had the lowest production compared to other the varieties. Meanwhile, ‘Bantaeng’ had the highest green shallot production, total nitrogen, and total phosphorus content in the leaf tissues. Total phenolic content fluctuated in the five varieties and observation times. The highest total phenolic content was in ‘Tuk Tuk’, observed 20 days after planting. The principal component analysis (PCA) showed that the five shallot varieties formed three clusters. The first was ‘Palasa’, the second cluster was ‘Bauji’, ‘Tuk Tuk’, and ‘Rubaru’, while the third cluster was ‘Bantaeng’. ‘Palasa’ had the highest content of leaf pigment, while Bantaeng had the highest leaf production. Leaf pigment and total phenolic content changed along with the increasing plant age in all varieties.

Abstract

Plant secondary metabolites are unique sources for pharmaceuticals and food additives. Orange jessamine (Murraya paniculata) contains secondary metabolite that is beneficial to human health including lowering blood cholesterol levels, anti-obesity, and has the antioxidant capacity. Leaves of orange jessamine have several chemical constituents including L-cadinene, methyl-anthranilate, bisabolene, β-caryophyllene, geraniol, Carene, 5-guaiazulene, osthole, paniculatin, tannins, eugenol, citronelled, coumurrayin and coumarin derivatives. This study aimed to determine the correlation between leaf concentrations of N, P and K with leaf bioactive compounds following chicken manure application to the plants. The experiment was conducted at IPB Experimental Station at Cikarawang, Bogor (6o30' - 6o45' S, 106o30'-106o45' E) from March to November 2014 (250 m above sea level). The study used a randomized block design (RBD) with rates of chicken manure as a treatment, i.e. 0, 2.5, 5 and 7.5 kg per plant. Chicken manure was applied at 30 months after planting (MAP). Leaves were harvested by pruning the plants to a height of 75 cm above the soil surface. The results showed that the optimum rates of chicken manure to produce maximum fresh and dry leaf weight were 3.1 kg and 6.5 kg per plant, respectively. This rate was sufficient for leaf production at the first harvest (34 MAP) but was insufficient for the second harvest (38 MAP). K concentration of the leaves from different positions within the plant and leaf age positively correlated with leaf dry weight (P <0.01), but negatively correlated with total flavonoid content (P <0.01). Leaf P concentration was negatively correlated with dry weight of the 5th young leaves, or mature leaves from all positions. Leaf K concentration was categorized very high (3.59-4.10%), whereas leaf P concentration was high (0.28-0.29%) to very high (0.33-0.35%). The 5th mature leaves determined plant K requirements.Keywords: antioxidant, bioactive compounds, leaf position, organic, NPK leaf concentrations

Abstract

Harvesting process is a critical time to identify the quality of raw material for traditional medicine. The time and harvesting techniques, drying process after harvesting, and processing to make the simplicia, are the crucial role to make the good quality of the natural product. On the other hand, there is a lack of general understanding and appreciation about the processes involved in governing shoot and tree growth and development, i.e. red guava.  The research objective was to evaluate the influence of leaf harvesting and growth phases on red guava for flavonoid production as antioxidant. Randomized factorial block design in time were laid out with two factors and followed by Duncan’s multiple range test. The treatments were the amount of leaf  harvested on tertiary branches (0, 25, 50, and 100%) and growth phases of the plant (vegetative and generative). Leaf harvesting 25% on tertiary branches significantly increased the leaf number (766.3 tree-1) and the number of new quarternary branches, decreasing leaf area index (LAI) and leaf dry weight at the end of the experiment (22 weeks of observation/WO).  The highest leaf dry weight (156.94 g tree-1) and LAI (0.47) was found in harvesting 25% tertiary branches.  Harvesting 100% leaf on tertiary branches in vegetative phase significantly produced the lowest flavonoid production (7.82 g tree-1). The result suggested that flavonoid production from red guava leaves should be done by harvesting 50% leaf on tertiary branches in generative phase can be used to produce the highest flavonoid (89.90 g tree-1).

Abstract

Black cumin cultivated in many subtropical regions in the world, including Asia, Middle East, and North Africa. The most active constituent of black cumin is thymoquinone representing 18.4%–24% of the volatile oil and thymol. Data about thymoquinone and thymol came from the country of origin, but no data from tropical region. This study aimed to analyze the production of chlorophyll, thymoquinone, thymol, and malondialdehyde from black cumin cultivated at three altitudes of Indonesian tropical region. The result showed that Kuwait accession cultivated at middle altitude contains the highest levels of thymoquinone (2940.43 mg/kg), and the highest levels of thymol were found in India accession cultivated at high altitude (141.46 mg/kg). Data showed that the level of malondialdehyde at low (220 meter above sea level [masl]) and middle (560 masl) altitudes is higher than high (1.280 masl) altitude.
