Rigidoporus Concrescens
''Rigidoporus microporus'' is a plant pathogen, known to cause white root rot disease on various tropical crops, such as cacao, cassava, tea, with economical importance on the para rubber tree (''Hevea brasiliensis''). White root rot of rubber ''Rigidoporus lignosus'' (klotzsch) Imazeki, the causal agent of white root rot, was first reported on rubber in 1904 from Botanical Gardens, Singapore. It belongs to the order Basidiomycete, and in the family Polyporaceae. The disease originates on roots and later spreads to collar region. Foliar symptoms are initiated subsequently with the destruction of the root system. Its above ground symptoms indicates that the trees are mostly beyond treatment and recovery, as rapid progress of infection makes death imminent. This disease caused significant mortality to tree irrespective of age or health status, causing economic losses to the latex industry in many countries. It is the most destructive root disease in rubber plantations in Sri Lanka a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Casper Van Overeem
Casper van Overeem (1 October 1893 – 28 February 1927) was a Dutch mycology, mycologist who pioneered the systematic study of tropical fungi in the Dutch East Indies (present‑day Indonesia). Initially trained as a teacher, he developed his scientific expertise under the botanist Hugo de Vries before earning his doctorate from the University of Zurich in 1920 with research on chromosome variations in ''Oenothera''. At Buitenzorg (now Bogor), he established a mycology department at the botanical gardens' herbarium and authored the illustrated series ''Icones Fungorum Malayensium'' alongside numerous scientific publications. His career was cut short by tuberculosis at age 33, but his meticulously detailed work and extensive collections established a foundation for tropical mycology, leading to multiple fungal taxa eponym, being named in his honour. Early life and education Casper van Overeem was born in Weesp, Netherlands, on 1 October 1893. He attended primary school in Weesp ...

Rigidoporus Lignosus
''Rigidoporus'' is a genus of fungi in the family Meripilaceae. Many of the species in this genus are plant pathogens. The widespread genus, which contains about forty species, was originally circumscribed by American mycologist William Alphonso Murrill in 1905. The generic name combines the Latin word ''rigidus'' ("rigid") with the Ancient Greek word ("pore").

Hevea Brasiliensis
''Hevea brasiliensis'', the Pará rubber tree, ''sharinga'' tree, seringueira, or most commonly, rubber tree or rubber plant, is a flowering plant belonging to the spurge family, Euphorbiaceae, originally native to the Amazon basin, but is now pantropical in distribution due to introductions. It is the most economically important member of the genus ''Hevea'' because the milky latex extracted from the tree is the primary source of natural rubber. Description ''Hevea brasiliensis'' is a tall deciduous tree growing to a height of up to in the wild. Cultivated trees are usually much smaller because drawing off the latex restricts their growth. The trunk is cylindrical and may have a swollen, bottle-shaped base. The bark is some shade of brown, and the inner bark oozes latex when damaged. The leaves have three leaflets and are spirally arranged. The inflorescences include separate male and female flowers. The flowers are pungent, creamy-yellow and have no petals. The fruit is a c ...

Tectona Grandis
Teak (''Tectona grandis'') is a tropical hardwood tree species in the family Lamiaceae. It is a large, deciduous tree that occurs in mixed hardwood forests. ''Tectona grandis'' has small, fragrant white flowers arranged in dense clusters (panicles) at the end of the branches. These flowers contain both types of reproductive organs (Plant reproductive morphology#Bisexual, perfect flowers). The large, papery leaves of teak trees are often Trichome, hairy on the lower surface. Teak wood has a leather-like smell when it is freshly milled and is particularly valued for its durability and water resistance. The wood is used for boat building, exterior construction, veneer, furniture, carving, turnings, and various small projects. ''Tectona grandis'' is native to South Asia, south and southeast Asia, mainly Bangladesh, India, Indonesia, Malaysia, Myanmar, Thailand, and Sri Lanka, but is naturalised and cultivated in many countries in Africa and the Caribbean. Myanmar's teak forests acco ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fungal Tree Pathogens And Diseases
A fungus (: fungi , , , or ; or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as one of the traditional eukaryotic kingdoms, along with Animalia, Plantae, and either Protista or Protozoa and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of motility, mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related organisms, named the ''Eumycota'' (''true fungi'' or ' ...

Root Vegetable Diseases
In vascular plants, the roots are the organs of a plant that are modified to provide anchorage for the plant and take in water and nutrients into the plant body, which allows plants to grow taller and faster. They are most often below the surface of the soil, but roots can also be aerial or aerating, that is, growing up above the ground or especially above water. Function The major functions of roots are absorption of water, plant nutrition and anchoring of the plant body to the ground. Types of Roots (major rooting system) Plants exhibit two main root system types: ''taproot'' and ''fibrous'', with variations like adventitious, aerial, and buttress roots, each serving specific functions. Taproot System Characterized by a single, main root growing vertically downward, with smaller lateral roots branching off. Examples. Dandelions, carrots, and many dicot plants. Fibrous RootSystem Consists of a network of thin, branching roots that spread out from the base of the stem, l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Non-food Crop Diseases
A nonfood crop, also known as industrial crop, is a crop grown to produce goods for manufacturing, for example fibre for clothing, rather than food for consumption. Purpose Industrial crops is a designation given to an enterprise that attempts to raise farm sector income, and provide economic development activities for rural areas. Industrial crops also attempt to provide products that can be used as substitutes for imports from other nations. Diversity The range of crops with non-food uses is broad, but includes traditional arable crops like wheat, as well as less conventional crops like hemp and Miscanthus. Products made from non-food crops can be categorised by function: See also * Biofuel * Bioplastics * Biopolymer * Cash crops * Cellulosic biofuel * Energy crop * Food vs fuel * Helix of sustainability * Intensive crop farming * National Non-Food Crops Centre * Renewable Energy Renewable energy (also called green energy) is energy made from renewable resourc ...
