Composition and structure diagram of sugarcane, as follows

Sugarcane (Saccharum officinarumL.) Sugarcane is a genus of tall, solid perennial herbs. Rhizomes are stout and well developed. Culms 3-5(-6) m tall. It is widely cultivated in southern tropical areas such as Taiwan, Fujian, Guangdong, Hainan, Guangxi, Sichuan, and Yunnan in China. Sugarcane is suitable for planting in places with fertile soil, abundant sunlight, and large temperature differences between winter and summer.

Sugarcane is a temperate and tropical crop that is used as a raw material for the manufacture of sugar and can be refined into ethanol as an energy substitute.

Sugarcane is produced in more than a hundred countries around the world, with the largest producers being Brazil, India and China. Sugar cane is rich in sugar, water, but also contains a variety of vitamins, fats, proteins, organic acids, calcium, iron and other substances that are very beneficial to human metabolism, and is mainly used in the production of sugar, the skin of the skin is usually purple and green two common colors, but there are also red and brown, but it is relatively rare.

Sugar cane is an annual or perennial tropical and subtropical herbaceous plant, a C4 crop.

Sugar cane cylindrical stems are erect, corky, tufted, and nodal, with buds at the nodes; internodes are solid and covered with a waxy powder, which is purple, red, or yellowish-green; leaves are tufted, and the blades have a plump, white midvein; the large panicle is terminal, with silvery hairs at the base of the spikelet, and the oblong or ovoid caryopsis is tiny.

Sugarcane is a tall solid perennial herb.

The rhizomes are stout and well developed. Culms are 3-5(-6) meters tall. 2-4(-5) cm in diameter, with 20-40 nodes, the lower internodes shorter and thicker, white powdered. Leaf sheaths longer than their internodes, glabrous except for pilose at mouth of sheaths; ligules very short, ciliate, leaf blades up to 1 m long, 4-6 cm wide, glabrous, midrib robust, white, margins serrate-scabrous.

The panicle is large, about 50 centimeters long, the main axis glabrous except for the nodes, not filiform pilose in the parts below the inflorescence; the racemes are mostly whorled, densely crowded; the internodes of the raceme axis are glabrous along with the spikelet pedicels; the spikelets are linear-oblong, 3.5-4 millimeters long.

Basal plate with filiform pilose hairs 2-3 times longer than spikelet; first glume veinless between ridges, not pilose, apical tip pointed, margins membranous; second glume 3-veined, midvein ridged, scabrous, glabrous or ciliate; first lemma membranous, subequal to glumes, glabrous; second lemma minute, awnless or reduced; second palea lanceolate; lodicules glabrous.
