s. The genus is divided into two subgenera based on the number of fibrovascular bundles in the needle. The subgenera can be distinguished by cone, seed, and leaf characters: * ''Pinus'' subg. ''Pinus'', the yellow, or hard pine group, generally with harder wood and two or three needles per fascicle. The subgenus is also named ''diploxylon'', on account of its two fibrovascular bundles. * ''Pinus'' subg. ''Strobus'', the white, or soft pine group. Its members usually have softer wood and five needles per fascicle. The subgenus is also named ''haploxylon'', on account of its one fibrovascular bundle. Each subgenus is further divided into sections and subsections. Many of the smaller groups of ''Pinus'' are composed of closely related species with recent divergence and history of hybridization. This results in low morphological and genetic differences. This, coupled with low sampling and underdeveloped genetic techniques, has made taxonomy difficult to determine. Recent research using large genetic datasets has clarified these relationships into the groupings we recognize today.

, which can kill some quickly. Some of these Lepidoptera species, many of them moths, specialize in feeding on only one or sometimes several species of pine. Beside that many species of birds and mammals shelter in pine habitat or feed on pine nuts.


Farming

When grown for sawing timber, pine plantations can be harvested after 25 years, with some stands being allowed to grow up to 50 (as the wood value increases more quickly as the trees age). Imperfect trees (such as those with bent trunks or forks, smaller trees, or diseased trees) are removed in a "thinning" operation every 5–10 years. Thinning allows the best trees to grow much faster, because it prevents weaker trees from competing for sunlight, water, and nutrients. Young trees removed during thinning are used for pulpwood or are left in the forest, while most older ones are good enough for saw timber. A 30-year-old commercial pine tree grown in good conditions in Arkansas will be about in diameter and about high. After 50 years, the same tree will be about in diameter and high, and its wood will be worth about seven times as much as the 30-year-old tree. This however depends on the region, species and silvicultural techniques. In New Zealand, a plantation's maximum value is reached after around 28 years with height being as high as and diameter , with maximum wood production after around 35 years (again depending on factors such as site, stocking and genetics). Trees are normally planted 3–4 m apart, or about 1000 per hectare (100,000 per km2).

Religious texts

Pine trees, as well as other conifers, are mentioned in some verses of Bible, the Bible, depending on the translation. In the

"And that they should publish and proclaim in all their cities, and in Jerusalem, saying, Go forth unto the mount, and fetch olive branches, and ''pine branches'' mphasis added and myrtle branches, and palm branches, and branches of thick trees, to mak
booths
as it is written."
However, the term here in Hebrew (עץ שמן) means "oil tree" and it is not clear what kind of tree is meant. Pines are also mentioned in some translations of Isaiah 60:13, such as the King James:
"The glory of Lebanon shall come unto thee, the fir tree, the pine tree, and the box together, to beautify the place of my sanctuary; and I will make the place of my feet glorious."
Again, it is not clear what tree is meant (תדהר in Hebrew), and other translations use "pine" for the word translated as "box" by the King James (תאשור in Hebrew). Some botanical authorities believe that the Hebrew word "ברוש" (bərōsh), which is used many times in the Bible, designates ''

Chinese culture

The pine is a motif in Chinese art and literature, which sometimes combines painting and poetry in the same work. Some of the main symbolic attributes of pines in Chinese art and literature are longevity and steadfastness: the pine retains its green needles through all the seasons. Sometimes the pine and cypress are paired. At other times the pine, plum, and bamboo are considered as the "
