EFFECTS OF MOROCCAN  WATERMELON MOSAIC VIRUS (MWMV) ON MINERAL COMPOSITION OF INFECTED Lagenaria breviflora (Benth) Roberty (Adenopus breviflorus)

ABSTRACT

The effects of Moroccan watermelon mosaic virus (MWMV) on the mineral composition of infected Lagenaria breviflora was studied. The seeds of L. brevifora were planted, inoculated with the virus (after nine days of planting) and some were left as control. After six weeks of inoculation, both the infected and the healthy (control) leaves were harvested separately, oven-dried at 70OC, pulverized and analyzed for mineral content. The virus caused significant reduction in the content of Ca with the percentage reduction of 10.7% (p<0.05) and K, with the percentage reduction of 26.2% (p>0.05) while the values obtained for Zn and Cu were significantly higher in infected than in healthy sample (p0.05). The results of this study revealed that virus alters the physiological and biochemical composition of the plant thereby reducing or increasing the nutritional quality of the plant.
