Topic: Andropogoneae


  
 [No title]
Members of the Andropogoneae differ from those of Paniceae in the reduced lemmas and paleas of their florets and, usually, in their paired, unequally pedicellate spikelets, disarticulating inflorescence branches (rames), and the manner in which these branches are aggregated into inflorescences.
The basic element of the inflorescence structure in the Andropogoneae is the spikelet unit.
Further complexity is introduced to the Andropogoneae inflorescence structure by the manner in which the spikelet units are aggregated and the mode of disarticulation.

The Andropogoneae is a tribe of the subfamily Panicoideae, together with the tribes Melinideae, Paniceae, and Tripsaceae.
The Andropogoneae tribe itself contains grasses that range from rhizomatous annuals to apomictic perennials, found primarily in the tropical, subtropical, and temperate zones of the world, but ranging further north and south with seasonal variations of warm and hot temperatures(Hitchcock, 1971).
As with most of the grasses, the grasses within Andropogoneae can usually reproduce in several different ways, are found as both annuals and perennials in varying environments, and exhibit hybridization quite frequently (Watson and Dallwitz, 1992).

Observation on pollen morphology of the tribe Andropogoneae (Gramineae).
Pollen morphology of 36 species in 34 genera belonging to 8 subtribes of the tribe Andropogoneae was examined and compared by means of light and scanning electron microscopy.
Based on the ornamentation, the pollen grains in the tribe can be divided into 3 types, namely scabrous, obscurely verrucate and obviously verrucate, which is useful in the research of systematic evolution.

 Sugarcane - Wikipedia, the free encyclopedia
A guide is available, as is general editing help.
Sugarcane or Sugar cane (Saccharum) is a genus of 6 to 37 species (depending on taxonomic interpretation) of tall grasses (family Poaceae, tribe Andropogoneae), native to warm temperate to tropical regions of the Old World.
They have stout, jointed fibrous stalks 2 to 6 meters tall and sap rich in sugar.

Winter temperatures are of special significance in temperate regions, while there is a striking relationship between high midsummer rainfall and relative abundance of species of Andropogoneae in the tropics and subtropics.
In general, the geographical survey supports conclusions drawn from taxonomic and cytological evidence regarding the origin and evolution of the tribe, but with greater emphasis on climate as a significant factor.
The Andropogoneae have had a long evolutionary history in the eastern hemisphere, but have spread more recently to the western hemisphere, where they have not yet attained their full development.

Once a very important cash crop in Hawaii, cultivation of sugar cane is no longer economically rewarding.
This particular tribe (Andropogoneae) of panicoid grasses typically has the spikelets in pairs (1 stalked, 1 sessile) along the axis.
Both Panicoid and Festucoid grasses typically have a flap of tissue called a ligule at the junction of the blade and sheathing portion of the leaf.

Our results unequivocally support a monophyletic Andropogoneae, but tribe Paniceae is clearly paraphyletic and is divided into two well-supported clades.
One clade comprises x=10 taxa; it is sister to the Andropogoneae with which it shares the base chromosome number.
Although Andropogoneae are exclusively C4-NADP-ME, C3 taxa are interspersed throughout the remainder of the Panicoideae and some are basal in each clade of the Paniceae.

A small rachis segment is expected in the connecting link between Andropogoneae and Maydeae in order to provide a smooth gradation in condensation level from Andropogoneae grasses such as Manisuris toward primitive maize such as the oldest Tehuacan cobs.
In Manisuris the rachis segments are about 5 mm long and extremely slender with a cupule-like structure formed by a sterile pedicel positioned along one margin of the internode.
