Musa acuminata

Musa acuminata

The Musa acuminata is a species of the genus of the banana ( Musa ) in the banana family ( Musaceae ).

Description

Following is the description of the wild form:

Musa acuminata grows as an evergreen perennial herbaceous plant, reaching heights of growth of about 5 meters, rarely up to 9 meters. The leaves are divided into leaf sheath, petiole and leaf blade. From the leaf sheaths of the pseudo - stem is formed, which has a diameter of about 25 centimeters. The rigid petiole is up to 80 inches long. The lamina is easily elongated with a length from 1.9 to 2.3 meters and a width of 50 to 70 centimeters.

The inflorescences are pendulous. The bracts are bright red to dark purple, sometimes at the top and yellow. The male flowers are in two rows, each about ten. The banana fruit is botanically berries are about 9 inches long and contain numerous seeds. The flat, brown seeds are 5-6 millimeters in size.

The wild form of Musa acuminata is diploid chromosome number 2n = 22 with a

Dissemination

The home of Musa acuminata is located in tropical Southeast Asia. Its distribution area covers Indonesia, Malaysia, the Philippines, Myanmar and Thailand; Occurrence is also available in the Chinese provinces of Guangxi and Yunnan, as well as in South India and Sri Lanka.

Meanwhile, Musa acuminata was widespread in the tropics worldwide. The species Musa acuminata and their varieties are sensitive to frost and take at temperatures just below 0 ° C damage.

System

The first description of Musa acuminata was made in 1820 by the Italian botanist Luigi Colla in Memorie della Reale Accademia delle Scienze di Torino, 25, pp. 394-395. There are known several Musa acuminata Colla synonyms for: Musa cavendishii Lamb, Musa chinensis Sweet nom. . nud. , Musa nana Lour. , Musa sinensis Sagot ex Baker, Musa zebrina Van Houtte ex Planch., Musa corniculata short, Musa rumphiana short, Musa Simiarum short.

Use

The data used as dessert bananas or plantain fruits comes in part from cultivars of this type; the varieties ' Cavendish ' and ' Gros Michel ' about are triploid Musa acuminata of mutants with a chromosome number 3n = 33 and some also include hybrids in culture, in which Musa balbisiana was crossed. During the nominate form seeds and fruit so apply the practical point of inedible, make all varieties farmed from seedless fruits and are therefore sterile ( although partially fertile pollen is formed).

Genetics

The wild form of Musa acuminata is diploid with a chromosome number 2n = 22 In 2012, the entire genome of double - haploid cultivar of Musa acuminata DH Pahang could be sequenced. It contains 523 mega base pairs on chromosome 11.
