What are the ways in which willow trees spread their seeds?

General News By Sophie Bennett 0 views
Willow trees spread their seeds by wind. Willow seeds generally mature in April to May, and the seeds are very small, with white down on them; because they scatter in the wind like drifting catkins, they are called willow catkins, and it is by the flying of willow catkins that willow trees spread their seeds to distant places to take root and sprout. Also spread by wind

Willow trees spread their seeds by wind. Willow seeds generally mature in April to May, and the seeds are very small, with white down on them; because they scatter in the wind like drifting catkins, they are called willow catkins, and it is by the flying of willow catkins that willow trees spread their seeds to distant places to take root and sprout. Poplars, dandelions and others also spread their seeds by wind.

Common willow varieties

1. Weeping willow

Its branches are slender and drooping, and its leaves are narrowly lanceolate or linear-lanceolate. It has strong vitality and is one of the common tree species, as well as a commonly used street tree in landscaping. It is cultivated throughout the Yangtze River basin and the Yellow River basin, and has been introduced and planted in countries across Asia, Europe and the Americas.

2. Dry land willow

Its branches are upright or obliquely spreading, its leaves are widest in the middle, and its base is rounded or broadly wedge-shaped. It likes light and is cold-resistant, and can grow in both wetlands and dry land. Its root system is well developed and its wind resistance is strong. It often grows in dry land or wet waterlogged land, and has not yet been introduced and cultivated artificially.

3. White willow

Its crown is broadly ovate, and its leaves are lanceolate to oblanceolate. The young leaves have silvery-white silky hairs on both sides; mature leaves are often hairless on the upper side and slightly downy or nearly hairless on the lower side. Its inflorescences are relatively long. It is cultivated in Xinjiang, Gansu, Qinghai, Tibet and other provinces and regions.

4. Purple willow

Its leaves are small, in a fine spindle shape, green and smooth. Its branches are relatively dense, and the plant is hemispherical. Its male inflorescences have sparse flowers, and the female flowers have 2 glands. Its flowering period is April. It is distributed in Hubei, Hunan, Jiangxi, Anhui, Zhejiang, Jiangsu and other provinces in China.
