Alocasia macrorrhizos is a species of flowering plant in the arum family that it is native to rainforests of Maritime Southeast Asia, New Guinea, and Queensland [1] and has long been cultivated in South Asia, the Philippines, many Pacific islands, and elsewhere in the tropics.
Alocasia is a genus of rhizomatous or tuberous, broad-leaved, perennial, flowering plants from the family Araceae. There are about 90 accepted species native to tropical and subtropical Asia and eastern Australia. [ 2 ]
Alocasia reginula, black velvet, is a species of flowering cormous aroid (family Araceae), native to Sabah state in Malaysia. [1] This plant, often referred to as one of the "jewel" Alocasias (along with several other diminutive Alocasia types), became increasingly popular among plant hobbyists between the years 2018 to 2020. Until as recently ...
Alocasia portei is a massive, thick-stemmed plant with a base that thickens even more with age. [3] [4] It can reach a height of 6 metres (20 feet) and sometimes 10 m (33 ft) in ideal environments. [3]
Alocasia infernalis is a species of flowering plant in the family Araceae, native to Kalimantan, Indonesia [citation needed] and Sarawak state, Malaysia. [1] It gets its specific epithet from its dark leaves—nearly black with purple veins—that exhibit a baleful red iridescence depending on the angle of the light and the position of the viewer. [2]
The propagation of shoots or nodal segments is usually performed in four stages for mass production of plantlets through in vitro vegetative multiplication but organogenesis is a standard method of micropropagation that involves tissue regeneration of adventitious organs or axillary buds directly or indirectly from the explants.
Micropropagation has a number of advantages over traditional plant propagation techniques: The main advantage of micropropagation is the production of many plants that are clones of each other. Micropropagation can be used to produce disease-free plants.
First described in Java by Marian Raciborski in 1900, taro leaf blight is caused by the oomycete Phytophthora colocasiae, which infects primarily Colocasia spp. and Alocasia macrorrhizos. [1] P. colocasiae primarily infects leaves, but can also infect petioles and corms. [2] Brown lesions on taro; Credit: Scot Nelson, University of Hawaii at Manoa
