Abstract Animal migration is highly sensitised to environmental cues, but plant dispersal is considered largely passive. The common dandelion, Taraxacum officinale, bears an intricate haired pappus facilitating flight.

Dispersal Mechanisms: Seeds can be dispersed long distances by wind because they move in updrafts. Longevity: Dandelion seeds are not long lived in the soil. Dormancy: The seed of dandelion are not dormant and can germinate immediately in the same year that they mature of the plant. Competitiveness:

Engineers uncover secret 'thinking' behind dandelions' seed dispersal by Caroline Brogan 01 June 2022 High on sunshine, humans often decide when dandelions get to spread their species - but the puffballs have their own ideas on how best to proliferate.

The dandelion seed has a fluffy structure that enables it to hold the most prolonged wind-based dispersal record. Commonly the seeds land 2 meters away from their mother plant. Still, in windy, dry weather favored by the dandelion, the seeds can fly up to 30 kilometers and even far (150 kilometers in some conditions).

Each dandelion seed is attached to a bundle of roughly 100 feathery bristles known as a pappus, whose name derives from an ancient Greek word for grandfather due to its resemblance to a beard.. As such, this plumed structure may prove ideal for the dispersal of the small, light seeds of short plants, whereas winglike membranes likely prove.

Summary: The fluffy dandelion seed head infuriates gardeners, but delights physicists. That's because those seeds may lend key insights into the physics of parachutes, useful for designing.

After pollination, the dandelion flower matures into a white fluffy "blowball". This comprises single fruits each attached to a tiny brush-like parachute called a "pappus" - which has about 100 individual bristle filaments. This structure allows the seed to remain aloft over distances of 100 km or more when the air is warm and dry.

Abstract: Long-distance dispersal of seeds (LDD) surely affects most ecological and evolutionary processes related to plant species. Hence, numerous attempts to quantify LDD have been made and, esp.

The seedhead is gray-white and spherical. Similar species: Redseed dandelion [Taraxacum laevigatum (Willd.) DC.] is very similar to dandelion but in contrast to that species, the terminal lobe of the leaf is about the same size as the lateral lobes, and the seeds are red to purple brown.

November 14, 2022 at 9:00 am You don't need a dandelion to know which way the wind blows. But it can help. On any given dandelion, some seeds are destined to go north, while others are fated.

This pappus facilitates enables the formation of a separated vortex ring (SVR) during flight ( 1 ); however, the pappus structure is not static but reversibly changes shape by closing in response to moisture. Here we characterise the biomechanical function of the pappus morphing regarding SVR dynamics and flight capacity.

Induced seed dispersal may be a strategy that allows adapted plants to escape from herbivores. 1. Background As sessile organisms, plants are mostly bound to grow and develop where they germinate. Local conditions are, therefore, important determinants of plant survival and reproductive success [ 1, 2 ].
