tailieunhanh - Performance of Dacryodes edulis mycorrhized layers under different cropping conditions in Makenene, Cameroon

Dacryodes edulis, with its potential dietary and medicinal uses, is an aging member of the agroforestry system and is classified among the priority species for domestication in Central Africa. Reliable techniques for producing quality planting materials other than seeds are urgently needed. | Turkish Journal of Agriculture and Forestry Research Article Turk J Agric For (2013) 37: 335-343 © TÜBİTAK doi: Performance of Dacryodes edulis mycorrhized layers under different cropping conditions in Makenene, Cameroon 1 2, 1 Martin MBEUYO , Nehemie DONFAGSITELI TCHINDA *, Emmanuel YOUMBI , 2 3 Hubert Jean Claude MBITA MESSI , Akoa AMOUGOU 1 Laboratory of Biotechnology and Environment, Faculty of Science, University of Yaounde I, 812 Yaounde, Cameroon 2 Medicinal Plants and Traditional Medicine Research Centre, Institute of Medical Research and Medicinal Plants Studies, 6163 Yaounde, Cameroon 3 Laboratory of Ecology, Faculty of Science, University of Yaounde I, 812 Yaounde, Cameroon Received: Accepted: Published Online: Printed: Abstract: Dacryodes edulis, with its potential dietary and medicinal uses, is an aging member of the agroforestry system and is classified among the priority species for domestication in Central Africa. Reliable techniques for producing quality planting materials other than seeds are urgently needed. The aims of this study were to produce D. edulis layers and integrate them into the cropping system. To promote rooting and the survival rates of layers, 4 treatments were used. The layers produced were inoculated with mycorrhiza and introduced into cropping systems for the evaluation of morphobiochemical parameters. The results show that of D. edulis trees are planted in cocoa plantations and in other cropping systems in Makenene. In addition, 12% of the plants are produced from technical improvement, and 88% from seeds. The use of honey significantly increased layer survival and rooting rates after 2 months. The mycorrhized layers grow better in fallow fields than among food crops or in cocoa-based agroforests. High levels of chlorophylls a and b, total proteins, total amino acids, and peroxidase activity .
