  • Effective Utilization of Citrus unshiu Plant Waste Extracts with Lipase
           Inhibitory Activities

    • Abstract: During the course of Citrus unshiu fruit cultivation, large amounts of plant material including pruned leaves, thinned-out flowers and unripe fruit are obtained; these materials are generally considered unusable and discarded as plant wastes. We have previously attempted to establish an effective use of such plant wastes as beneficial natural resources and found that a methanolic extract of pruned Citrus leaves (CUL-ext) exhibited inhibitory activity against porcine pancreatic lipase. In this study, we sought to identify further the effective uses of C. unshiu plant wastes by determining the lipase inhibitory activity of methanolic extracts of thinning out flowers (CUF-ext) and unripe fruit (CUUF-ext). We accordingly found that the inhibitory activity of CUF-ext was superior to that of CUUF-ext and comparable to that previously observed using CUL-ext. Fractionation of CUF-ext and CUUF-ext, followed by chromatographic analyses, revealed that the pancreatic lipase inhibitory activities of these extracts could be attributed, at least in part, to the flavonoids hesperidin, nobiletin, narirutin and rutin. On the basis of present findings, we propose that, in addition to pruned Citrus leaves, the thinned-out flowers and unripe fruit of C. unshiu are natural resources which are suitable for preparing constituents with lipase inhibitory activity.

  • Enset (Enset ventricosum (Welw.) Cheesman) Breeding for Various Purposes -
           A Review

    • Abstract: Enset (Enset ventricosum (Welw) Cheesman) is a well-known cultivated crop in Ethiopia and a cultural staple food for over 20 million humans in different parts of Ethiopia. It bears flowers that developed into fruits and seeds. It bears seeds and propagated vegetativly. Attempts have been done for maintenance, conservation, improving cultivars, diversity, and variability study. About 623 Enset germplasm were collected from 12 main growing areas and ex-situ conserved at Areka. Seeds of Enset were stored at the millennium gene bank. Seedlings and specimens are held in the garden of Cambridge Cottage and Wakehurst. In the research effort 6 cultivars: 3 early set cultivars: Yanbulle, Gewada, Endale, and 3 late set cultivars: Kelisa, Zerita, Mesena were released. Variability study revealed that corn yields were significantly affected by location, cultivar, and cultivar Vs location. Genotypes: Suite, Warke, Bidu, Astera, and Kekari showed 100% disease symptoms after 30 days of inoculation. Symptoms weren't observed on Meziya, Bedadet, Hiniba, and Nech Enset clones after 90 days of inoculation. ISSRs primers revealed that, in all parameters, Kefficho genotypes have been more diversified than genotypes from Essera areas. The Partitioning of Shannon's diversity index indicated that the major variations were occurred within populations than between the two populations.

  • Variability, Heritability and Genetic advance of introduced upland rice
           genotypes at Fogera in North Western Ethiopia

    • Abstract: Variability, heritability and genetic advance are basic in order to provide information for plant breeding programs. Forty nine upland rice genotypes were tested in 7*7 simple lattice design at Fogera in Wereta station of Adet Agricultural Research Center in 2012/13. The objectives of the study were to estimate the genetic variability, heritability and genetic advance of the genotypes tested. Analysis of variance revealed that there was highly significant difference among the 49 genotypes for all the characters studied. Accessions IR 78937-B-3-B-B-1 and IR 78937-B-3-B-B-2 had the highest yield with a score of 5374.5 kg/ha and 5305.6 kg/ha respectively. The high yielding genotype IR 78937-B-3-B-B-1 had a yield advantage of 57% and 22.2%, respectively, as compared to standard checks Nerica-4 and Hidasie. Phenotypic coefficient of variation (PCV) values ranged from 2.5% for panicle length to 49.98% for number of spikelet per panicle. While the genotypic coefficient of variation (GCV) ranged from 2.4 % for panicle length to 47.6 % for number of spikelet per panicle. Number of tiller per plant (22.47%), number spikelet per panicle (49.98%), thousand seed weight (25.56%) and yield (23.93%) had higher PCV values. The PCV values for flag leaf length (14.79%), flag leaf width (16.12%), and culm length (16.42%) and number of panicle per plant (16.32%) were medium. Flowering cycle (7.81%), maturation cycle (2.9%), and panicle length (2.5%) had lower PCV values. GCV values were low for flowering cycle (7.21%), maturation cycle (1.82%) and panicle length (2.4%); medium for flag leaf length (14.26%), flag leaf width (15.39%), culm length (15.19 %) and number of panicle per plant (15.72%); high for number of tillers per plant (22.18 %), yield (23.07%), thousand seed weight (25.18%) and number of spikelet per panicle (47.60%). The high GCV values of these characters suggest that genetic impact is higher and environmental influence is lower. This study generally had indicated that there was significant genetic variability or divergence among the genotypes. Thus, the improvement program of the upland rice genotypes through direct selection rather than a lengthy crossing program is recommended.

  • Available Phosphorus in Soils Amended with Organic N-Enriched Composts
           during Periods of Incubation

    • Abstract: Inorganic nitrogen (N) fertilizers, microbial inoculum and biologically-active substances are used to fortify composts which characteristically contain low amounts of N. The potentials of organic wastes from agriculture for N enrichment of composts were indicated by significant increase in soil N while there can be fortuitous improvement in the available phosphorus (P) contents on which information about the extent is lacking. In this study, composts: cow dung + sawdust (CDSD) and poultry droppings + sawdust (PDSD) were enriched with meals from bone (BN), blood (BM), hoof (HF) and horn (HN); and neem leaf (NM) and tithonia leaf (TM) to attain 150, 300, 450 and 600 g kg-1 N and the available P was monitored at four-week intervals during 16 weeks of incubation in soil. Available P increased with all N sources and enrichment rates slightly at week 4 but highly from week 8 and for each source, the enrichment to 600 g kg-1 N gave the highest values. The composts enriched to 450 and 600 g kg-1 N gave 15-20 and 20-29 mg kg-1 available P in week 12 and 16 respectively. CDSDBM and PDSDHF enriched to 600 g kg-1 N at week 4 and 8 respectively can be used for short-season crops while PDSDBM and PDSDNM enriched to 600 g kg-1 N in week 12 and 16 respectively would be suitable for long-season crops. The PDSDNM enriched to 600 g kg-1 N gave the highest available P (29.0 mg kg-1) and was followed by PDSDBN and PDSDHF at the same enrichment level, with 28.0 mg kg-1 each. Although the PMSDNM enriched to 600 g kg-1N had the highest available P in week 16, the enriched composts with values exceeding 20 mg kg-1 also have potentials for the cultivation of long-season vegetables.

  • In vitro Bioassay of Allelopathic Activities of a Mangrove Tree, Kandelia
           obovata, and Fast-growing Trees, Betula platyphylla and Populus alba,
           Using Protoplast Co-culture Method

    • Abstract: Allelopathic activities of a salt-tolerant and low-temperature tolerant mangrove tree, Kandelia obovata, which grows in brackish water regions of sub-tropical areas, and two fast-growing trees, Betula platyphylla and Populus alba, which grow in the temperate area, were examined by two in vitro bioassay methods, the sandwich method using dried leaves and the protoplast co-culture method using leaf protoplasts. Lettuce root growth examined by the sandwich method, was inhibited 50% by 50 mg dried mature leaves of K. obovata. In the protoplast co-culture method, inhibition rates of cell division of lettuce protoplasts were 31% and 69% by leaf protoplasts of K. obovata at densities of 1 × 104 mL-1 and 5 × 104 mL-1, respectively. These results were compared with the inverse relationship between allelopathic activities and salt tolerance of mangrove plants of different families. B. platyphylla showed 37% inhibition by the sandwich method using dried young leaves, but only 10% inhibition at 5 × 104 mL-1 by the protoplast co-culture method using leaf protoplasts of B. platyphylla. Dried young leaves of P. alba showed 66% inhibition, but the leaf protoplasts at the density of 5 × 104 mL-1 showed highly stimulatory activity. Abscisic acid, of which contents in leaf protoplasts of three tree species varies from high to low in relation to salt tolerance and recalcitrance of tissue culture, was discussed as a putative allelochemical.
