How to propagate Persian Silk trees

Persian Silk trees wood is solid, and are used for furniture, farm tools, construction and shipbuilding due to their strong, straight, structural, and durable timber. Persian Silk trees, known as sensitive plants, have been listed as the preferred tree species for seismic observation. So How to propagate Persian Silk trees? Here are propagation methods of Persian Silk trees.

How to propagate Persian Silk trees

Persian Silk trees are typically seeded and harvested in September and October, using plump, pest-free pods that are dried and purged in dry ventilation to prevent mold growth.

Raise seedlings in spring, soak seeds for 8-10h before sowing and then take them out for sowing. Furrow sowing was carried out, the furrow spacing was 60cm, and the soil was covered by 2-3cm. After sowing, the bed soil was kept moist and germinated for about 10d. The seeding capacity of 1h㎡ is about 150kg. The management of weeding, weeding and topdressing should be strengthened after seedling emergence. In the 2nd year, plant at 3-5m apart in spring or autumn. Weeding pine nests every spring and autumn for 2-3 years after transplanting to promote growth. 

Persian Silk trees seed treatment

The seeds should be treated between March and April of the following year before sowing. 2 weeks before sowing, it should be soaked in cold water solution of 0.5% potassium permanganate for 2h. After extraction, it should be washed with clean water and soaked in hot water around 80℃ for 30s (the longest time should not be more than 1min, otherwise the germination rate will be affected). Sowing can be carried out after 24h. Using this method to accelerate the germination rate can be up to 80%-90%, and the seedlings after robust growth are not easy to come on.
