About
Juglans regia is a large deciduous tree with impair pinnate leaves. The wood is even grained and is greyish-brown with dark brown streaks. It attains a height of 80-100' or even more. It has a wide natural range of distribution and is found in pure as well as in mixed form. In wild state it is found usually from 5000' to 10,000' and in cultivated form it is found from 3,500' to 10, 000'. It occurs chiefly on deep well drained and fertile soil on sheltered situations such as moist ravines or depressions. Pure crops are found on lower gentle slopes of well drained depressions the parts of which are occupied by coniferous forests. (6) It is also found mixed with horse chestnut, maple, oak, bird cherry or with conifers particularly spruce, fir and blue pine In west Pakistan it is commonly found in Hazara, Murree, Swat, Dir, Chitral, Gilgit and Baltistan. The timber of walnut is moderately hard even, grained. Sapwood is greyish- white and heartwood is brown with darker streaks. It is very durable, works well and does not warp or split. It is used for furniture, cabinet making, carving and for gun-stocks. It is found to be the best wood for gun-stocks so there is always a demand for it. The tree is often cultivated for its valuable fruit. Wild trees are lopped for fodder. Spirit is extracted from leaves which is used in checking the sick- ness of pregnancy. Bark is used to clean the teeth and strengthen the gums. It is also used as an astringent, anthelmintic and lactifuge. Outer bark is used as a dye in Kashmir. An oil is extracted from the fruit which is used internally as a teanicide especially for tapeworms and is a mild laxative. Externally it is used in in case of dimness of vision. (4)
