What is the difference between poplar catkins and willow catkins? Teach you to tell them apart at a glance

I. Differences

1. Different sources: Poplar catkins grow from poplar trees and are the seeds of the poplar. After the poplar flowers mature and split open, they drift out. Poplar flowers have no nectary and cannot secrete nectar to lure insects to spread pollen, so they can only rely on the wind to spread pollen, making them wind-pollinated flowers. Willow catkins grow from willow trees. Although they look very similar, they come from a different source: they are the seeds of the willow. Willows have unisexual flowers and no perianth, but they do have nectaries, and can use nectar to lure insects to spread pollen, making them insect-pollinated flowers.

2. Different times of appearance: Poplar catkins generally appear first and can last for a week. Willow catkins appear later, generally after the poplar catkins.

3. Different texture: Poplar catkins are more cohesive and can clump together, feeling like cotton. Willow catkins have finer fibers and are more scattered and light.

4. Different dispersal distances: Poplar catkins mostly come in clumps and are a bit heavier, so they travel shorter distances. Willow catkins are lighter and can be carried farther by the wind.

II. How to suppress the flying catkins

After poplar catkins and willow catkins appear, they have a certain impact on people's lives. To solve the problem of flying catkins, you can cut the trees down directly and plant other trees that do not produce flying catkins. You can also inject chemicals, which can inhibit them from producing seeds and prevent the flying catkins from appearing. You can also plant only male trees, which likewise produce no seeds and no flying catkins.
