[What is Rhodiola Rosea]

Rhodiola Rosea (also known as Arctic root or golden root) is a member of the family Crassulaceae, a family of plants native to the arctic regions of Eastern Siberia. Rhodiola rosea is widely distributed  in Arctic and mountainous regions throughout Europe and Asia. It grows at altitudes of 11,000 to 18,000 feet above sea level.

There are numerous animal and test tube studies showing that rhodiola has both a stimulating and a sedating effect on the central nervous system; enhance physical endurance; improves thyroid, thymus, and adrenal function; protects the nervous system, heart and liver; and has antioxidant and anticancer properties.

4 Protecting cardiovascular, dilating coronary artery,preventing coronary arteriosclerosis and arrhythmia.

Eucalyptus is a fast growing, medium- sized to tall tree attaining 20-50m in height and upto 2m in diameter. The tree has a deep tap root system with mycorrhizal associations which increases its ability to draw nutrients and water. The tree has a smooth silvery white stem. The leaves are leathery in texture, hang obliquely or vertically and are studded with glands containing aromatic oil. Flowering takes place during July-August. Flowers in bud are covered with a cup- like membrane, which is thrown off as a lid when the flower expands. The fruiting occurs during September – October. The fruits are surrounded by a woody, cup-shaped receptacles and contain numerous minute seeds.

Silvicultural Characteristics

Eucalyptus is versatile, fast growing and strongly coppicing tree possessing a wide range of soil and climatic adaptability.
The species grows under a wide range of climatic/soil conditions from warm to hot, sub humid to humid and from good to degraded soils. The range of agro-climatic conditions of the species is given as under:

Soil and Physiography

Soil texture : light, medium, heavy
Soil drainage : Free, seasonally waterlogged
Soil reaction : acidic, neutral
Special soil tolerances : saline
Soil types : alluvial soils, gravely soils, ferral soils, red soils, sandy soils

Yield

The mean annual increment in volume overbark of medium quality sites at age 5-6 years is about 15 cu m/ha. Wood yield of 120 tonnes/ha has been reported in red sandy clay loam soils, under irrigated conditions in Karnataka.

Commercial uses of Eucalyptus

Eucalyptus is one of the fastest growing trees and is an excellent timber for paper and pulp, particleboard and hardboard industries.
It is also an excellent source of fuelwood and charcoal.
Eucalyptus wood is also used for light and heavy construction, railway sleepers, bridges, piles, poles and mining timber.
Indian Standards are available for use of Eucalyptus timber, after treatment, for door frames, window shutters, furniture, cabinet, tool handles, packing cases and crates.
Leaf extracts of the species have pesticide properties and can be promoted as a biopesticide.
The wood and bark of the tree have a tannin content of 6-12% and 3-15% respectively, though not used as a commercial source of tannin.
Eucalyptus is a large ornamental tree suitable for parks and avenue plantations.
The tree may be used as an agro-forestry species. Eucalyptus in combination with pineapple have given excellent results in China.
• The tree species can be effectively used for regeneration of denuded lands and prevention of soil erosions in drought -affected areas.
Unit cost and Economics

Unit cost for raising Eucalyptus under high density plantations 1.5m x 1.5m has been worked out to 4444 plants per hectare. Considering harvesting at the age of 5 years.

Unit Cost for raising Eucalyptus hybrid in 1 ha. of wasteland
Spacing : 1.5m x 1.5m.
No. of plants per ha. 4444

Seed storage behaviour is orthodox. Viability can be maintained for several years in hermetic storage at 3 deg. C with 6-10% mc. A germination rate of 8% following 10 years of open storage at room temperature has been reported. There are approximately 320 000-600 000 viable seeds/kg.

In chemistry, a coordination complex or metal complex consists of a central atom or ion, which is usually metallic and is called the coordination centre, and a surrounding array of bound molecules or ions, that are in turn known as ligands or complexing agents. Many metal-containing compounds, especially those of transition metals, are coordination complexes.
