Where do pine tree seeds come from?

When the pine fruit is ripe, there are many small pieces on it. Each small piece contains a seed as big as a melon seed. There is a thin layer on the outside of the seed, which looks very much like wings. Every time the pine cone is ripe, this part will open.

What do pine seeds look like?

The seeds of the pine tree are very small, light brown in color, with a smooth and shiny shell. After the pine fruit has grown and matured for a period of time, its scales will open, and the seeds can be seen at this time, and then the pine seeds will fall off immediately.

Pine Seed Dispersal

When the pine fruit is ripe, the seeds inside will automatically fall to the ground and can grow under suitable conditions. In addition, many birds feed on pine cones and will drop the seeds to the ground after digestion. In addition, pine seeds can also be transported by wind.

How to get pine seeds

When the pine cones mature, their scales will open and then the seeds will fall off quickly. For a few varieties, the process of scale opening and seed falling takes a long time. The fruits are easily blown off by the wind before and after they mature. You can pick them by climbing the tree or hitting them with a bamboo pole.

How to keep pine tree seeds

Pine seeds can be harvested in time after they mature, piled up in alkali for about 15 days and exposed to the sun, cracked and sieved, and then stored in a dry state.

Pine seed planting

1. In March and April every year, male and female cones will grow on new branches of pine trees. The growth time is roughly the same, but the maturity time is different. The male cones mature quickly and release pollen. The pollen enters the female cones but does not germinate. It is not until the spring of the following year that pollen tubes grow to complete fertilization. Then the female cones develop rapidly and form seeds.

2. Pine seeds are generally sown in March and April, but due to different climates in different places, the sowing time will also be different. The southern region generally plants around the Qingming Festival, and the northern region generally plants in mid to late April.

3. Pine seeds need to be germinated before sowing. You can choose the common seed soaking or stratification method. Soak the seeds in warm water one week before planting, rinse once a day, check for cracks, and then arrange sowing.
