Material uses
The needles contain a substance called terpene, this is released when rain washes over the needles and it has a negative effect on the germination of some plants, including wheat[4]. Oleo-resins are present in the tissues of all species of pines, but these are often not present in sufficient quantity to make their extraction economically worthwhile[5]. The resins are obtained by tapping the trunk, or by destructive distillation of the wood[6][5]. In general, trees from warmer areas of distribution give the higher yields[5]. Turpentine consists of an average of 20% of the oleo-resin[5] and is separated by distillation[6][5]. Turpentine has a wide range of uses including as a solvent for waxes etc, for making varnish, medicinal etc[6]. Rosin is the substance left after turpentine is removed. This is used by violinists on their bows and also in making sealing wax, varnish etc[6]. Pitch can also be obtained from the resin and is used for waterproofing, as a wood preservative etc.
Wood - soft, light, not strong, brittle, very coarse grained[7][8][9]. It weighs 31lb per cubic foot[10]. Of very little value for its wood, it is sometimes used for fuel and charcoal[7][8][9].Medicinal uses(Warning!)

Cultivation
A slow-growing tree in its native habitat[14], though it can produce seeds when only a metre tall[9]. Very few trees are being grown in Britain, it would seem to be of moderate growth in this country, averaging 25 - 30cm a year for the first 30 years or so[15]. Many trees are small and stunted in Britain[13]. A tree in Sussex was 17 metres tall in 1985[7]. The cones are 5 - 8cm long[9]. They ripen in their second year and open and shed their seed whilst still attached to the tree[9][16], though they sometimes remain closed for 2 - 3 years before shedding their seed and can persist on the branches for 20 years[9]. Plants are strongly outbreeding, self-fertilized seed usually grows poorly[2]. They hybridize freely with other members of this genus[2]. Leaf secretions inhibit the germination of seeds, thereby reducing the amount of plants that can grow under the trees[17]. The resin from a broken shoot has a scent like lemon-curd[15].
Plants in this genus are notably susceptible to honey fungus[2].Crops
