Plant parasites cause lasting genetic changes

As plants try to strengthen their defenses against nematodes, those parasites try to outsmart them. New research shows that nematode species that move from plant to plant cause more than mechanical damage.

Bumblebees hate pumpkin pollen, which may help pumpkins

A new study finds that squash and pumpkin pollen have physical, nutritional and chemical defense qualities that are harmful to bumblebees.

Grant funds high-tech system to improve grapevine pruning

Researchers from Cornell and Pennsylvania State University are developing a high-tech, portable imaging system that will increase profits and yields by making winter grapevine pruning more efficient.

Variety challenges ‘Jaded’ attitudes toward green tomatoes

Genetics, not field conditions, makes hemp ‘go hot’

Cornell researchers have determined that a hemp plant’s propensity to “go hot” – become too high in THC – is determined by genetics, not as a stress response to growing conditions.

Genetic marker discovery could ease plant breeders’ work

Transferring genetic markers in plant breeding is a challenge, but a team of grapevine breeders and scientists at Cornell AgriTech in Geneva, New York, has come up with a powerful new method.
