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[11]. 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[12]. The resins are obtained by tapping the trunk, or by destructive distillation of the wood[13][12]. In general, trees from warmer areas of distribution give the higher yields[12]. Turpentine consists of an average of 20% of the oleo-resin[12] and is separated by distillation[13][12]. Turpentine has a wide range of uses including as a solvent for waxes etc, for making varnish, medicinal etc[13]. 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[13]. Pitch can also be obtained from the resin and is used for waterproofing, as a wood preservative etc.
Wood - coarse-grained, light, soft, not strong. Occasionally used for fuel and second class lumber[9][14][15].Medicinal uses(Warning!)

Cultivation
This species is not hardy in the colder areas of the country, it tolerates temperatures down to between -5 and -10°c[8]. A short-lived tree in Britain. It is slow to get established but it then grows strongly[20]. Of moderate growth in height with increases of about 30 - 40cm a year, but of rapid increase in girth, about 3 - 5cm a year[21]. Trees grow better in the southern part of the country[20]. Trees do not often bear cones in Britain[17][18]. A tree planted in 1954 at Kew was about 12 metres tall in September 1993 and was carrying a number of large cones[K]. The summer had been cool and damp[K]. The same tree had another good crop of cones in the autumn of 1996 and continues to cone quite well in 1999[K]. An 11 year old tree at Kew had two small female cones in January 1999[K]. The fresh cones can weigh 2.2 kilos and when dried in a warm room for a year or so still weigh ½ kilo. The cones open and shed their seed whist still attached to the tree[22]. The seeds are ejected explosively from the dry cone over a period of several weeks[21]. The cones are 25 - 35cm long[9], they can hang on the tree for a number of years with their seed intact[18]. This species is closely related to P. sabiniana[15]. Leaf secretions inhibit the germination of seeds, thereby inhibiting the growth of other plants below the tree[23]. Plants are strongly outbreeding, self-fertilized seed usually grows poorly[8]. They hybridize freely with other members of this genus[8].
Plants in this genus are notably susceptible to honey fungus[8].Crops
