Variable short internodes
--Gregory G. Doyle
Variable short internodes (vsi) is a recessive mutant that arose
spontaneously. Its expression is quite unusual. There are clusters of short
internodes generally from 2 to 4 in number which are from 2.5 to 4cm in
length. The other internodes are of normal length. These clusters are usually
at the base of the plant although they may be found anywhere on the plant.
In a few cases two clusters of short internodes were found on the same
plant. It is possible that vsi is a temperature sensitive mutant
and a minor cold wave in the early spring sets up this phenotypic response.
