Squirting cucumbers, or Ecballium elaterium, disperse seeds by explosively propelling them out through high internal pressure. Research conducted at Kiel University reveals the mechanics behind this process. The fruit's pericarp contracts, leading to violent expulsion of the mucus-like liquid containing seed pods. This movement is enhanced by structural changes in the fruit as it loses moisture. While considered invasive in some areas, it has ornamental qualities and serves as a potent laxative, though it can also be toxic if consumed inappropriately.
The squirting cucumber, also known as Ecballium elaterium, propels its seeds explosively as internal pressure builds up, forcing a stream of liquid containing seed pods out at high speeds.
The mechanism of squirting is facilitated by the contraction of the pericarp and structural changes in the fruit as it dehydrates, leading to a rapid seed dispersal action.
Despite its unique dispersal method, the squirting cucumber is not the most effective seed dispersal strategy, providing insight into plant adaptations for survival.
While often viewed as a weed, the squirting cucumber also has potential ornamental value and its fruit extract can be toxic if misused.
