World’s Largest and Useful Grass Bamboo
About world’s one of the Fastest Growing, Largest and Useful Grass Bamboo
Bamboo is the most unusual group of perennial evergreens in the true grass family. Indeed it does not look like the common variety of grasses we see in the garden or on the moors. Still Bamboo is a grass family of Poaceae. Bamboo looks more like a tree or a tall bush. Giant bamboos are the largest members of the grass family.
Bamboo is one of the fastest-growing plants on Earth that grows at a phenomenal speed of about 41 centimeters a day and can reach up to a height of 35 metres in 24 hours. However, the growth rate is dependent on local soil and climatic conditions as well as species and a more typical growth rate for many commonly cultivated bamboos in temperate climates is in the range of 3–10 cm (1–4 inches) per day during the growing period. The intermodal part of the stem is hollow and smooth. The vascular bunches in the cross section are scattered throughout the stem instead of in a cylindrical arrangement.
There are numerous joints in the stem. Unlike grass and other tree the xylem is absent in bamboo the absence of secondary growth wood causes the stems of monocots, even of palms and large bamboos, to be columnar rather than tapering. There are about 500 different varieties found in different parts of the world. Most bamboos flower annually but few varieties bloom only 3 or 4 times in 100 years.
All types of bamboo grow in tropical and sub-tropical climate in Asia, South America and Africa. Some tall varieties of bamboo have been successfully planted in Florida and California. Bamboos are of notable economic and cultural significance in South Asia, South East Asia and East Asia, being used for support to building materials, as a food source, and as a versatile raw product. Since ages bamboo has been one of the most useful plant for people living in tropical zones. It is widely used in making cots, chairs, tables, posts, rafts, walking sticks, baskets, fishing poles, flute and many musical instruments like table, veena etc.
Few people have constructed their house including roofs walls, floors using only bamboo. Some varieties of bamboo are so hard that crude knives are made from these. In china the inner pulp is used for making special kind of paper.
In Japan hollow bamboo stems are used as water pipes in gardening. In many countries including India, tender shoots of some bamboo varieties are eaten as vegetable and are used for making pickles.
Timber is harvested from cultivated and wild stands and with the larger bamboos of special species called as Phyllostachys, are known as “timber bamboos”.
Bamboo is no doubt is the most powerful and useful grass for mankind.
