  • Diversification of Tree Crops: Domestication of Companion Crops for Poverty Reduction and Environmental Services
    Expl Agric. (2001), volume 37, pp. 279±296 Printed in Great Britain Copyright # 2001 Cambridge University Press REVIEW PAPER DIVERSIFICATION OF TREE CROPS: DOMESTICATION OF COMPANION CROPS FOR POVERTY REDUCTION AND ENVIRONMENTAL SERVICES By R. R. B. LEAKEY{ and Z. TCHOUNDJEU{ {Centre for Ecology and Hydrology, Bush Estate, Penicuik, Midlothian, EH26 0QB, Scotland, UK and {International Centre for Research in Agroforestry, PO Box 2067, YaoundeÂ, Cameroon (Accepted 19 January 2001) SUMMARY New initiatives in agroforestry are seeking to integrate indigenous trees, whose products have traditionally been gathered from natural forests, into tropical farming systems such as cacao farms. This is being done to provide from farms, marketable timber and non-timber forest products that will enhance rural livelihoods by generating cash for resource-poor rural and peri-urban households. There are many potential candidate species for domestication that have commercial potential in local, regional or even international markets. Little or no formal research has been carried out on many of these hitherto wild species to assess potential for genetic improvement, reproductive biology or suitability for cultivation. With the participation of subsistence farmers a number of projects to bring candidate species into cultivation are in progress, however. This paper describes some tree domestication activities being carried out in southern Cameroon, especially with Irvingia gabonensis (bush mango; dika nut) and Dacryodes edulis (African plum; safoutier). As part of this, fruits and kernels from 300 D. edulis and 150 I. gabonensis trees in six villages of Cameroon and Nigeria have been quantitatively characterized for 11 traits to determine combinations de®ning multi-trait ideotypes for a genetic selection programme.

  • Chemical Studies on the Parasitic Plant Thonningia Sanguinea Vahl
    RSC Advances PAPER View Article Online View Journal | View Issue Chemical studies on the parasitic plant Thonningia sanguinea Vahl† Cite this: RSC Adv.,2018,8, 21002 Ama Kyeraa Thomford, ab Reda Fouad Ahmed Abdelhameedac and Koji Yamada*a Thonningia sanguinea Vahl plays an important role in traditional medicine in many African cultures. A study of the n-hexane fraction of the whole plant of T. sanguinea led to the isolation of two glucocerebroside 0 molecular species TSC-1 and TSC-2, one b-sitosteryl-3b-D-glucopyranoside-6 -O-fatty acid ester molecular species, TSS-1, and seven known triterpenes (1–7). The ethyl acetate fraction also afforded five known lignans (8–12) and one known flavanone (13). Their structures were elucidated by means of chemical and spectroscopic methods (methanolysis, NMR and mass spectrometry). Spectral analyses of the glucocerebrosides revealed mainly sphingosine-type (TSC-1) and phytosphingosine-type (TSC-2) cerebrosides, with both possessing mainly 2-hydroxy fatty acid and b-D-glucopyranose moieties. TSS-1 was found to be a b-sitosterol-type with fatty acid methyl esters and b-D-glucopyranoside moieties.

We measured removal and ripening rates of fruits having different exposure to insolation and frugivory. The fruits ripened and were removed very slowly. There was no difference in proportion of ripe to green fruits between the compared localities. We suggest M. leucantha, a light demanding herb, has adapted to dynamic gap matrix in tropical forest by having prolonged fruiting season. Its fruit can either be taken by primary dispersers to newly created gaps, or split open by themselves. Released seeds containing arils may be dispersed within or in proximity to the parental gap by secondary dispersers like ants. Myrmecochory is rarely studied in tropical forests, which makes this finding particularly interesting. Ingella Jansson, Umeå University, Sweden Joanna Reszka, Jagiellonian University, Poland 2001 Spatial distribution of large trees: Competition or not? Abstract The relationship between distance and size of near neighbour large trees was investigated to find out if their spatial distribution is determined by competition. We found no correlation between tree size and nearest-neighbour distance, thus rejecting the hypothesis of a competition-determined distribution. The spatial distribution of large trees was found to be clumped and not uniform. Together these results suggest that competition is a weak force in determining spatial patterns amongst big trees.

Received 28 September, 2018; Accepted 2 April, 2019 Plukenetia conophora fresh leaves were obtained from a farm in the Surulere Local Government Area of Oyo State, Nigeria. The plant is a climber which normally found support in kola nut or cocoa tree. Standard method was used for the extraction of the oil. The oil was analyzed using gas chromatographic and gas chromatography coupled with mass spectrometric methods. Fifteen compounds were identified in the leaves. The most abundant compounds in the oil were oleic (9- octadecenoic) acid (29.8%) and palmitic (hexadecanoic) acid (14.36%), while the less abundant compounds are 6-tridecenoic acid (9.05%) and 9-octadecenoic acid,1,2,3-propanetryl ester (6.24%). The characteristic of this oil is the presence of long chain fatty acids. This study seeks to evaluate the chemical constituents of the oils of P. conophora leaves and how to harmonize them in pharmaceutical and industrial uses.

China 2 School of Life Sciences, Anhui Agricultural University, Hefei, 230036, P.R. China Abstract The enzyme strictosidine synthase (STR, EC: 4.3.3.2) plays a key role in the biosynthetic pathway of terpenoid indole alkaloid (TIA). It catalyzes the condensation of the tryptamine and secologanin to form 3α(S)-stricto- sidine, which is the common precursor of all TIAs. In this paper, a STR gene designated as DoSTR (GenBank: KX068707) was first cloned and characterized fromDendrobium officinale with rapid amplified cDNA ends method (RACE). DoSTR has a length of 1380bp with 1179bp open reading frame encoding 392 amino acids. BlastP analyses showed that its amino acid sequence was classified into Str_synth superfamily. qRT-PCR showed that DoSTR was expressed in all tissues tested, with a significantly higher level in flower and the lowest in stem. Four different treatments with MeJA, SA, ABA and AgNO3, respectively, could induce the DoSTR expression to a different extent. And the effect of MeJA was the most obvious and transcript level of DoSTR induced by MeJA was 20.7 times greater than that of control at 48 hours after treatment.

Against this background, ethyl acetate extract of the leaves were screened against some microorganisms so as to ascertain this claim and to recommend it for further investigation for possible inclusion into official compendium. The plant leaves were dried, powdered subjected to cold maceration with ethyl acetate for 24 hours. Phytochemical screening was done for alkaloids, saponin, essential oil, phenolic group, steroidal nucleus, simple sugar, starch, cyanogenic glycoside, proteins and flavonoid using standard procedures. Antimicrobial screenings were done using agar diffusion technique. Antibacterial activity test was conducted by screening against six pathogens comprising both Gram-positive and Gram-negative bacteria obtained from pharmaceutical microbiology laboratory stock. The extract was screened against 24 hour broth culture of bacteria seeded in the nutrient agar at concentrations 400, 200, 100, 50, 25, 12.5, 6.25 and 3.125 mg/ml in DMSO and incubated at 37oC, for 24 hours and measuring the inhibition zone diameter - IZD.
