Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Stocks of Vitellaria paradoxa (Shea tree) plant in the wild are increasingly threatened by land transformation and harvesting and there is need to propagate this tree to avoid its going into extinction and also encourage commercial plantation of this plant. In vitro callus initiation of Vitellaria paradoxa was developed. The experiment was set up using complete randomized design. Each concentration of plant growth hormone was poured into four bottles and five explants cultured. The first experiment was done to achieve the best surface sterilization protocol for its tissue culture since there is no standing protocol. The best decontamination was achieved by surface wiping a 3 to 4 days old leaf with 70% ethanol and then soaked in 3% sodium hypochlorite for 20 minutes, prior to this procedure the explants was washed with detergent and tween 20 (polyoxyethylene(20) sorbitan monolaurate). The surfaces of 3 to 4 days old leaf explants were exposed to a range of different concentrations of plant growth regulators. The treatment of explants with single concentrations of auxins (2,4-D: 2,4-dichloroxyphenoxyacetic and Pichloram) did not initiate callus after 3weeks up to 12 weeks. 88 pp. Englisch.…

Taschenbuch. Condizione: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - African rice gall midge (AfRGM), (Orseolia oryzivora Haris and Gagne) is a major constraints associated with lowland rice production. Varietal resistance is an important component in the management of the pest. The aim of this study is to evaluate level of AfRGM resistance in inter-specific rice progenies lines. Field experiments were conducted in 2009 cropping season at Badeggi and Edozhigi to screen 917 inter-specific rice progeny lines for AfRGM resistance. The field was laid out in an Augmented Block Design, comprising of three blocks with 305 progenies in each block, checks were randomized three times in each block. The result was analyzed using the Resistance Index Analysis. Sixteen progenies selected with the three checks (FARO 37, FARO 52 and Tog 7442) were subjected to yield trial in 2010 cropping season at Badeggi. The experimental design was a randomized complete block design (RCBD). Field screening of the progenies revealed that there was significant difference in their resistance to AfRGM, 4 progenies were found to be resistant across the two locations. However, 7 out of the 146 progenies that had good phenotypic acceptability were resistant at Badegg.…
