Sweet potato fasciation

John Rumfelt brought his weird looking Beauregard sweet potato vine in to the station wondering why it looked so strange. It is fasciated – flattened and ribbed – due to hormonal imbalance from a mutation or other factors. Fasciation is not contagious and John told Leslie Akers that the vines had a good amount of sweet potatoes. I have seen this symptom on highbush blueberry and apple branches, but this is the first time I saw a fasciated sweet potato! To read more about fasciation, see Fascinating Fasciation at https://hort.purdue.edu/ext/fascinatingfasciation.html

This sweet potato vine is fasciated showing a flattened, ribbed stem.

Ningxia University Students Visit Fruit Station

Viticulture and Enology students from the Ningxia University in China visited the Fruit Station today for some hands on learning. The students arrived in Springfield in September and will be attending Missouri State University.  Today some of the students came to Mountain Grove for some hands on experience in the vineyard.  They harvested Vidal Blanc and Chambourcin grapes.  The Vidal Blanc grapes were then put through the stemmer-crusher and a basket press.  The juice was filtered and drank.  The Chambourcin Grapes were put into the cooler.  The students also received a tour of the winery and distillery.  The students were led by Dr Martin Kaps, Susanne Howard and C.J. Odneal.  Dr. Wenping Qiu provided the Ningxia faculty with a tour and helped us out with translation.
