An arrangement of nine points (related to the Pappus configuration) forming ten 3-point lines.. In discrete geometry, the original orchard-planting problem (or the tree-planting problem) asks for the maximum number of 3-point lines attainable by a configuration of a specific number of points in the plane.
Fusarium mangiferae is one of the causal agents of malformation disease that affects mango (Mangifera indica, L.) growing regions and is economically important. [3] [4] [5] It causes mango malformation disease (MMD) and induces vegetative development abnormalities in shoots that leads to misshaped buds, short internodes, dwarf and narrow leaves.
Mango malformation Fusarium subglutinans (Note: some debate remains as to complete etiology of this disease.) Mucor rot Mucor circinelloides. Mushroom root rot Armillaria tabescens. Phoma blight Phoma glomerata. Phyllosticta leaf spot Phyllosticta mortonii Phyllosticta citricarpa Guignardia citricarpa [teleomorph] Phyllosticta anacardiacearum
Roads, sidewalks and foundations can all suffer structural issues from tree roots. [7] Several methods of control have been attempted, from barriers to encouraging growth in desirable directs. Selection of plants with root systems that will not conflict with nearby structures is the most effective method of damage control.
Mangifera indica, commonly known as mango, is an evergreen [3] species of flowering plant in the family Anacardiaceae. [4] It is a large fruit tree, capable of growing to a height and width of 30 m (100 ft). [5] There are two distinct genetic populations in modern mangoes – the "Indian type" and the "Southeast Asian type". [6]
Mangrove plants require a number of physiological adaptations to overcome the problems of low environmental oxygen levels, high salinity, and frequent tidal flooding.Each species has its own solutions to these problems; this may be the primary reason why, on some shorelines, mangrove tree species show distinct zonation.
Hydraulic redistribution is a passive mechanism where water is transported from moist to dry soils via subterranean networks. [1] It occurs in vascular plants that commonly have roots in both wet and dry soils, especially plants with both taproots that grow vertically down to the water table, and lateral roots that sit close to the surface.
Oidium mangiferae is a plant pathogen that infects mango trees causing powdery mildew. [1] Powdery mildew of mango is an Ascomycete pathogen of the Erysiphales family that was initially described by Berthet in 1914, using samples collected from Brazil. [ 2 ]
