| Abstract:
Spatial patterns of spread of floral malformation among genetically diverse cultivars of mango (Mangifera indica L.) was investigated. The disease progress curves of both regular and alternate bearing cultivars were sigmoid and bimodial respectively. The spread of the disease was faster in regular bearers than that of the alternate bearing cultivars. The rate of spread of the disease within the plant assumed logarithmic growth after the secondary source of inoculum was established in the plant. Disease gradient curves in all the cultivars were hyperbolic, but that of regular bearing cultivars was flatten near the source soon after initiation of the disease. The disease reached long distance in step wise progression. The direction of disease gradient curves corroborated with the direction of rain drop drift in June-July. | |
