The female cycad has a rounded cone that holds the seed, while males produce a taller slender cone that contains pollen. Asian cycad growers cut off the male cone when it is ready to release its ...

A tropical plant has produced male and female cones outdoors in the UK for the first time in 60 million years, in an event that botanists say is a clear indication of climate change.

A. You can't until a plant produces a cone. The sago, Cycas revoluta, is not really a palm but a member of the genus Cycad. Cycads have been around for more than 200 million years, and sagos, like ...

Cycad female cones produce heat (several degrees centigrade over ambient temperature) when ready to be pollinated. And, without flowers, coonties create odors to attract insects to gather pollen ...

Scientists discovered a strange reproductive method in primitive cycad plants: The plants heat up and emit a toxic odor to drive pollen-covered insects out of male cycad cones, and then use a ...

The goal behind the cycad’s chemical blitz was clear. Concentrated beta-myrcene is toxic to thrips and the insects flee the cones to avoid it, taking grains of pollen with them.

The thrips feed on cycad pollen, which is contained in whitish sacs visible under the cone scales. As the odor dissipates, thrips are attracted back to the cones, but some mistakenly go to female ...

The only known wild Wood's cycad was discovered in 1895, and it has since been cloned into many male trees. Now, researchers are scouring a forest in South Africa for an elusive female specimen ...
