Do monoecious pine trees blossom and bear fruit in spring?

Pine is a monoecious plant, the most obvious feature is that the leaves are needle-like, often 2-needle, 3-needle or 5-needle bunch, and in people's common impression, the pine tree has no flowers. So will pine trees blossom and bear fruit in spring? According to Master Xiao, a pine grower in Loudi, pine trees not only bloom, but also both male and female. The female cones are single or 2-4 planted at the top of the new branches, and most of the male cones gather in the lower part of the new branches. The cones of pine trees generally bloom in spring and summer, and the flowering time of different varieties of pine is different, for example, cedar: flowering period is from October to November; Masson pine: flowering period is April; black pine: flowering period is April-May; Pinus tabulaeformis: flowering period is April-May; loblolly pine: flowering period is March-April; Pinus elliottii: florescence is April-May; Pinus elliottii: florescence is late March. Japanese five-needle pine: the flowering period is May. In addition, after pollination, the female flower will bear pine nuts.

Master Xiao also revealed that after the bees or the wind passed the male flower pollen to the female flower, it did not germinate until the end of spring and early summer the following year, so that the female flower fertilized and developed into a cone (commonly known as pine tower or pine cone, not fruit). The cones mature after autumn and the seed scales open, each with two seeds.

Most of the species of pine are tall and straight trees with good material and there is no shortage of pillars. Pinus koraiensis, the "king of wood" in northeast China, Pinus koraiensis, a tall tree species widely distributed in western North America (up to 75 meters high), Pinus radiata, which is native to the coast of California, USA, Pinus elliottii, and Pinus elliottii, etc., are famous timber species.

The ornamental value of pine trees is also obvious to all. In China, pine trees can be seen from royal classical gardens to modern residents' homes, such as Pinus tabulaeformis and white bark pine in Beihai and the Summer Palace in Beijing, five-needle pine widely used in tree stump bonsai, and some famous mountain resorts. The mountain is strong and the pine is famous for its mountain. Welcome pine in Huangshan, Huashan pine in Huashan, beauty pine in Changbai Mountain. All of them are admired by visitors.

In addition, macrofungi often grow in the roots of pine trees. Some of them are wood-rot fungi, which can decompose pine trees and cause root rot; some are ectomycorrhizal fungi, which can exchange nutrients with pine trees to prevent nutrient deficiency, thus affecting their growth.
