Abstract

Dioscorea spp. is local tuberous food crop that has potential as alternative food source to support food security program in Indonesia. Exploration study and collecting mission subjected to Dioscorea spp. have been conducted in Nganjuk Regency. The study was aimed to 1) determine the distribution of Dioscorea spp. in Nganjuk, 2) to characterize tuber’s morphological characteristic, and 3) to know how tuber’s utilization by local peoples. The results showed that there were 4 species of Dioscorea found in Nganjuk. They are Dioscorea alata L, Dioscorea esculenta (Lour.) Burkill, Dioscorea hispida Dennst and Dioscorea bulbifera L. Dioscorea alata (uwi) is the most cultivated by farmers in Nganjuk. It has the largest cultivar numbers which  consists of 11 cultivars. Dioscorea esculenta (gembili) consists of 3 cultivars and Dioscorea hispida (gadung) consists of 4 cultivars, whereas Dioscorea bulbifera (uwi gantung) consists only 1 cultivar in one location. Farmers and local peoples play important role in conservation of Dioscorea in Nganjuk region by cultivating and utilizing it as alternative food source for home consumption.

Abstract

Banana Bunchy Top Disease (BBTD) caused by Banana Bunchy Top Virus (BBTV) is one of the most serious banana diseases, constraint and devastate to the local and regional banana production. Some of banana cultivars were more readily infected by the virus, but considering no cultivars is resistant. The incidences of BBTD and the type and severity symptoms in natural conditions without any artificial inoculation were recorded. The observations results on 2009 showed that 12.14% of the total accessions indicated positively infected BBTD. The BBTD incidences were increased rapidly about twofolds per year, 28.57% in October 2011 and 54.29% in October 2011. The spread and development of BBTD is optimum at humid, high rainfall intensity and temperatures, high soil fertility and also low light intensity or shaded. The latest monitoring on February 2012 (62.14%) comprises of 64 accessions were positively infected and 39 accessions were symptomless. Those symptomless accessions were initially indicated as tolerant banana cultivars to BBTD e.g. Pisang Kepok (BBB), Pisang Sobo (BBB), Pisang Bandung (ABB), Pisang Nangka (AAB), Pisang Candi (AAB) and  Pisang Raja Marto (AAB). These preliminary results are in agreement with several previous studies indicated that genotypes with one or two B genomes tend to be more tolerant to BBTD. However several cultivars which known tend to BBTD tolerant are indicated susceptible to Blood Disease. Some cultivars also showing complication symptoms both BBTD and Blood Disease.

Abstract

Aims of this research were to describe the morphology and analyze nutrient values of mature fruits at three different genomic groups of Indonesian banana cultivars including Pisang Berlin (AA), Ambon Hijau (AAA), Raja Bandung (ABB) and Kepok (ABB). Fruit characterization results show that each banana cultivar had specific characteristics related to their genomic group. Pisang Berlin has bright yellow peel and pulp, sugary taste. Pisang Ambon Hijau has fine curved fruit shape, sweet taste and aromatic. Pisang Raja Bandung has medium thickness and yellow peel, firm flesh, sweet and slightly acidic taste. Pisang Kepok has thick coarse and yellow peel with dark brown blotches, mild sweet taste. Fruit characters of Pisang Berlin and Ambon Hijau are close related to their ancestral parents’ Musa acuminata wild species, whereas Pisang Kepok and Pisang Raja Bandung as hybrid cultivars have intermediate characters between Musa acuminata and Musa balbisiana wild species. Nutrient analysis revealed that mature banana pulp contain of high carbo-hydrates (16.72-35.24 g 100g-1), total sugar (12.12-20.82 g 100g-1), vitamin C (16.45-30.27 g 100g-1) and potassium (275-375 g 100g-1); moderate protein (1.48-1.78 g 100g-1) and low fat (0.03-0.08 g 100g-1). About 100 g edible portion of banana fruit produce 73.43 to 148.80 calories.

Abstract

ABSTRACTStudy on foliar anatomic structure of tropical plants are useful to study various aspects of plant life related to photosynthetic, productivity, carbon sequestration, adaptation to environmental stresses as the results of global climate change, etc. This study was conducted to investigate foliar anatomic structure of ten tropical woody plant species including Barringtonia asiatica, Dracontomelon dao, Heritiera littoralis, Diospyros discolor, Calophyllum inophyllum, Antidesma bunius, Schleichera oleosa, Syzygium cumini, Madhuca longifolia dan Adenanthera pavonina; also to discuss its implication to ecophysiological adaptation to tropical dry climate. The results showed that ten woody plant species studied had variation of adaptation pattern to dry tropical climate, exposure to high light intensity or open shade and photosynthesis activity. Plant species in Group II (Antidesma bunius, Madhuca longifolia and Adenanthera pavonina) has relatively higher adaptation compared to Group I (Diospyros discolor, Calophylum inophyllum, Dracontomelon dao, Schleichera oleosa, Heritiera littoralis, Baringtonia asiatica and Syzygium cumini). Some foliar anatomic structures including palisade shape and size, stomatal index, stomatal density, spongy mesophyll thickness, the ratio of P/T and P/S are important characters that can be used as indicator of changes in environmental factors; particularly the density of stomata as indicators of climate change in dry tropic area.Keywords: adaptation, dry climate, eco-physiology, foliar anatomy, woody plant

Abstract

Water yam (Dioscorea alata L.) is an important tuber crop containing essential nutrition as an alternative food source. This study aimed to analyze the biochemical composition and nutritional value of fresh tuber of fifteen local accessions of water yam from East Java and followed by the accession selection for the recommendation of accession with the best nutritional value. Results showed that the nutritional value of proximates including moisture, carbohydrate and fiber were significantly different; except in protein, fat, and ash, with the range of moisture (65.47-82.46%), carbohydrate (17.10-29.37%), protein (1.29- 3.00%), fat (0.00-0.29%), fiber (6.70-11.62%) and ash (0.85-1.44%). The ranges of mineral contents (mg/100g) were K (224.54-483.21), Ca (15.63-61.97), Mg (16.75-43.06), Fe (1.40-13.40), Zn (0.43-2.83) and P (329.37-699.91); Na mostly not detected. The anti-nutritions contents (mg/100g) comprised tannin (63.36-167.68) and oxalic acid (12.73-44.92). Analysis through HCA showed three clusters with a range of similarity from 67% to 96%; through PCA scatter biplot clearly illustrated the variation and correlation pattern among local accessions. Six promising accessions are recommended for further breeding and development i.e. Uwi Perti/30, Uwi Bangkulit/36, Uwi Bangkulit/42, Uwi Bangkulit/43, Uwi Biru/58 and Uwi Legi/66, based on their highest carbohydrates and protein content, and the lowest fat content.

Abstract

Indonesia, being part of the center of origin of bananas (Musaceae), has a large number diversity of bananas both wild seeded species and edible seedless cultivated varieties. Inventory of wild Musa species in Purwodadi Botanic Garden has been conducted through compiling data records from PBGs Registration section, field inspection and observation to living collections in the garden, herbarium specimens and literature studies. The results show that total 17 wild Musa accessions has been recorded planted in Purwodadi Botanic Garden since 1990 until 2012; comprises of 8 Musa acuminata sub species, 2 Musa balbisiana forms, 1 Musa ornata, 1 Musa troglodytarum, 1 Musa borneensis and 4 unidentified species Musa spp.; but only 8 living accessions remained in 2012. Morpho-taxonomic review of those 8 wild Musa accessions remained will be discussed in this paper including their geographical distributions. According to its differentiated morphological characteristics observations, it is known that there are three accessions were resembled cultivars and one unidentified species have been determined its species level, so that their registration identity needs to be revised. It is important next to prioritize ex-situ conservation of wild Musa species not yet collected in Purwodadi Botanic Garden especially from Eastern Indonesia.
