Can you eat pine nuts from all pine trees As titled, thank you

Not all pine seeds are edible. All I know is that red pine seeds and white pine seeds can be eaten, and they can also be used in medicine. For example, pine seeds are not edible, the seeds of sand pine are poisonous and cannot be eaten, and female cypress pine can be used as medicine but not edible.

Not all of them can be eaten, Rui, Hua, and insomnia.

Common pine trees have pine nuts, but not all pine trees can bear edible pine nuts, there are many kinds of pine trees, such as Korean pine, masson pine, Huashan pine, tabuliformis pine, whitebark pine, sylvestris pine, etc. There are many types of pine trees, the vast majority of which can grow 20 to 50 meters, and the highest can reach 75 meters.

Most of the pine nuts eaten are the fruits of red pine, and although there are pine nuts such as Huashan pine and whitebark pine, the pine nuts are obviously small and not suitable for eating. Korean pine has strong photophilicity, high requirements for soil moisture, and should not be too dry, too wet soil and severe cold climate. It grows better in cold, rainy climates with high relative humidity and deep, fertile, well-drained, acidic brown forest soils.

Korean pine is produced in the Changbai Mountains, Jilin Mountains and Aihui Mountains of Xiaoxing'an Mountains in Northeast China, 150-1800 meters, with a cold, humid climate and brown forest land. The southern climate is hot, which is obviously not suitable for the growth of Korean pine.

The characteristics of the pine nut trees that can be eaten are as follows:Evergreen tree that can grow up to 40 m tall and 1 m DBH. The leaves are scaly, triangular, 3-6 cm long, 5-10 mm wide at the base, with sharp edges.

The leaves can grow for 10-15 years and cover most of the trees except the trunk and old branches.

dioecious, male and female cones on different trees. The male cones (pollen) are oval-shaped, initially 6 cm long, and when pollen is released, they grow to 10-18 cm long and 15-25 mm wide. The female cones (seeds) mature in autumn after 18 months of fertilization, spherical, 18-25 cm in diameter, containing 100-150 seeds, about 5 cm long, and the cones are released by cracking when ripe.

GrowthBrazilian pine nuts, flowering period of 5 weeks, fruiting period of September to October, pine nuts in the pine cones ripe and dry after falling one after another, the picking time is generally from mid-September to mid-October. A pine tower lasts about 3 years from flowering to maturity, and the yield is extremely limited, so it is extremely valuable. It takes a month for pine nuts to be ripened, picked, transported to processed and shipped out of the factory.

In November, it will be sold to our country.
