Elemental Content of a Susceptible and a Resistant Varieties of Plantain (Musa paradisiaca L.) to Cigar-end Rot Disease

C.L. Igeleke and D.K.G. Ayanru    

Abstract: Floral and fruit tissues of two cultivars of plantain (Musa paradisiaca L.), P100-F (susceptible) and P200-I (resistant to cigar-end rot disease), grown side by side in a field plot in Benin City, Nigeria, were analysed for eight mineral elements-N, P, K, Ca, Mg, Fe, Na and Zn. Calcium, sodium and zinc concentrations were higher in bracts (0.151, 0.265 and 0.490%) and immature peel (0.520, 0.629 and 0.063%) of the P100-F than in samples of the P200-I cultivar (0.077, 0.210 and 0.032%) and (0.482, 0.490 and 0.032%), respectively. Concentrations of P and K were significantly lower in all tissues analysed of the susceptible (P100-F) than the resistant (P200-I) cultivar. The relevance of these results in relation to the management of cigar-end rot disease of plantain is discussed.
