Willow is how to spread seeds second grade as follows:

1, spread seeds by wind. Willow seeds generally mature in April to May, the seeds are very small, white fluffy, because the wind scattered as flakes and called willow flakes, and willow is by the willow flakes to spread the seeds to far away to take root and germinate, the same by the wind to spread the seeds of poplar, dandelion, etc..

2, spread by animals. Animals passing by the willow tree, may be stained with willow flakes. When the animal walks to other places, the willow flakes may fall and the seeds grow there.

3, spread by body. The so-called body propagation, that is, by the plant body itself, it does not rely on any medium of transmission, after maturity, the fruit or seed will fall directly to the ground due to gravity. This is the body propagation.

Willow Introduction

1, concept: willow is a general term for a class of plants, willow species, easy to hybridize. Hybrid growth potential and adaptability, easy asexual reproduction, can be selected from within the natural or artificial hybrid population, through asexual reproduction, to obtain excellent asexual varieties; in addition, can also be used in plant tissue culture methods to quickly obtain a large number of high-quality saplings. Breeding mainly for garden ornamental, should focus on improving its branches and leaves and tree shape, to improve the ability of anti-pollution, resistance to pruning and shaping.?

2, morphological characteristics: trees or creeping, cushion-like, erect shrubs. Branches cylindrical, pith nearly round. No terminal bud, lateral buds usually close to the branch, bud scales single. Leaves alternate, sparsely opposite, usually narrow and long, mostly lanceolate, pinnately veined, serrate or entire; petiole short; stipules, mostly serrate, often caducous, rarely persistent. Catkins erect or obliquely spreading, opening before leaves, or at same time as leaves, rarely after leaves; bracts entire, hairy or glabrous, persistent, rarely caducous; seeds small, mostly dark brown.

3, the growth environment: willow belongs to the wide ecological amplitude of plants, the adaptability of the environment is very wide, light-loving, moisture-loving, cold-resistant, is the middle-growth wet species. But some species are also more drought-resistant and saline tolerance, in the ecological conditions of the poorer places to grow, in the favorable conditions of the plains of the plains, growth is better. General life expectancy of 20 to 30 years, a few species can reach more than 100 years.
