Seeding Is Believing
I have recently been accused, by one of my colleagues, of writing overly long blog entries. At first I got a bit defensive, but then I realized how right he was. And so, it is with great respect to the blogospheric code of brevity, that I ask you all to contemplate one, simple, non-hyperlinked question today: Where do you find the seeds to grow seedless watermelons?

Genetic engineering and selective breeding / hybridization. These plants are not sustainable.

The obvious question asked about growing seedless watermelons is: "How does one obtain seed of a seedless watermelon?" Obviously, you cannot save seed from a seedless watermelon. So, where do the seeds come from? Simply stated, the number of chromosomes (the threadlike bodies within cells that contain the inheritance units called genes) in a normal watermelon plant is doubled by the use of the chemical colchicine. Doubling a normal (diploid) watermelon results in a tetraploid plant (one having four sets of chromosomes). When the tetraploid plant is bred back, or pollinated, by a diploid or normal plant, the resulting seed produces a triploid plant that is basically a "mule" of the plant kingdom, and it produces seedless watermelons. Seed of seedless varieties are available from most major seed companies. from http://aggie-horticulture.tamu.edu/extension/newsletters/hortupdate/may00/h5may00.html.
