                A VEGAN SOLUTION TO SEA LEVEL RISE?

Volumes have been written on capturing carbon in  trees, but not much on limiting sea level rise by sequestering water in crops. 

This may change,  for Salon suggests grafting watermelons onto Giant Pumpkin vines as the Next Big Thing in biogeoengineering:







Dr. Todd Wehner, a distinguished professor of Horticultural Sciences at North Carolina State... said so-called giant watermelons are technically defined as any watermelon weighing over 32 pounds that has been grown in a field. However, when growing these massive mutants... the process looks a little different.

Usually, it starts with a giant watermelon transplant... These transplants can be put on a non-watermelon rootstock —like a squash — to get a bigger plant. After growing several plants, a grower will decide which one is doing best, and thin them down to the one that looks most promising. As watermelons are native to the temperate regions of west Africa, they need warm temperatures during the day and a long growing season to succeed.

Key to the watermelon's size is its roots. The branch for the fruit can be rooted multiple times. Watermelons are notoriously heavy feeders, meaning that they require more nutrients than average plants...

Genetics play a role in the success of a giant watermelon's size, too. Similar to growing giant pumpkins, seeds that have been bred from giant watermelons carry the genetic code for enormity. Regulating the amount of water that goes to the plant is also moderated.

"Too much water will cause the fruit to split," Wehner says. "It's a very well cared for fruit."

In a twist that wouldn't surprise Sigmund Freud, the giant melon–ogling community is mostly "male-dominated," but there are some women growers like Susie Zuerner, a 62-year-old living in North Carolina. Like Dawson and Vial, Zuerner's interest in growing huge watermelons piqued after seeing them at the North Carolina State Fair. In 2010, Zuerner grew a 239-pound watermelon. She hasn't been able to match her record yet, but for her it's not about the competition.
