Cycads are dioecious, so cycad cones are either male or female. Examine the egg for the germinal disc, a white spot floating above the surface of the yolk. Floating seeds in water will usually tell if seeds have gone bad in the hands of others. Epidemiology has shown a subsequent increase in ALS-PD in the years following this. In their native habit, Cycads are pollinated by wind or insects, however, in cultivation, they usually must be hand-pollinated for viable seed production. The germinal disk of a sterile egg contains only the hen’s cells and is fully white in color. fertile seeds. If the seeds dry out to an extreme, the developing embryo can die. The people of Guam depended heavily on flour made from the starch extracted from cycad seeds, particularly when there were food shortages during and after World War II. Cycads typically don't produce female cones for the first time until they are much older … Included are suggestions … Was about to ask about an easier way to clean the seeds.

In simple terms, this means that cycads do not produce true flowers or fruit, just one or more large seed cones. Cycad plants are hardy, evergreen gymnosperms (cone-bearing plants) that grow in sand or hard rock. Producing a cone and nourishing the developing seeds takes a toll on the female plant. There are over 300 described species of cycads living today, in 10–12 genera and 3 families (and several more extinct genera and families). Because cycads are a group of cone-bearing plants that are the oldest seed plants in the world. In my South Texas greenhouse operation, 100 mature male and female Cycas revoluta - over 25 years old - are ground-planted as seed "parents". I red somewhere that the seeds might need to be stored before planted depending on species. Sat with a knife yesterday for more than an hour and I have about 15 seeds semi clean. Cycad seeds like to stay slightly moist. As much as 60% of the starch content of the stem can be used up for the production of seeds. Cycads are dioecious plants; there are separate male and female plants. The mature seeds tend to be colorful – often bright red, purple or yellow – to attract a variety of birds and mammals which disperse the seeds. Cycads species are capable of growing in dry and wet conditions, in sand or fertile soils.
