This is a call for papers to be presented at the
92nd Annual Meeting of The Potato Association of America. This meeting will
be held August 10-14, 2008 at the Adam’s Mark Hotel, Buffalo, New York,
USA.
PAA invites submission of papers dealing with all facets of the potato industry.
Applied research and Extension-oriented submissions suitable for a grower-oriented
half-day afternoon session are encouraged. Graduate students who are PAA members are
encouraged to enter the “Frank L Haynes Graduate Student Research Competition”.
Members are required to submit abstracts for papers they wish to present, whether
orally, as a poster, or in the Frank L Haynes Graduate Student Research
Competition. Prior to submitting your abstract, please carefully read and follow
the formatting guidelines outlined below.
At the annual meeting, all oral paper presentations will be of a uniform 15-minute
length. Authors should plan a 12- to 14-minute presentation with the balance of
time devoted to questions. Computer projectors will be available for PowerPoint
presentations. Please bring your PowerPoint presentation on a portable
USB drive. Display boards will be provided for the poster papers.
The abstracts for all papers (oral, poster and Graduate Student Competition)
presented at the Annual Meeting will be published in a post-meeting issue of the
American Journal of Potato Research. Abstracts of papers listed in
the meeting program, but not presented, will not be published in the AJPR.
Abstracts will be accepted until March 21, 2008. Submit abstracts as an
e-mail attachment to loretta.mikitzel@gnb.ca
with “PAA Abstract” as the e-mail subject. Abstracts submitted after that date will be
returned to the author.

Impact of cultural practices on glycoalkaloid levels in Atlantic, Marcy and Snowden.

High concentrations of total glycoalkaloids (TGA) are a concern in selected cultivars
and it is important to have a better understanding of the impact that cultural practices
may provide on TGA levels in newly released cultivars. The newest Cornell release,
Marcy (NY112), was compared to Atlantic, known for low TGA levels and Snowden, known
for higher levels of TGA. Because both Marcy and Snowden are late in maturity it was a
concern that cultural practices that might delay plant maturity and harvest might
negatively impact TGA levels. A randomized complete block design of four replications
was conducted during the 2000 and 2001 seasons at our Freeville, NY research farm.
Three cultural practices were employed: nitrogen rates of 167, 222 and 278 kg
ha1; mid-September and mid-October harvest; and artificially bruising tubers
(dropping 20 times from 50 cm). Total glycoalkaloids were determined 45 days after
harvest at the University of Maine, Orono. Highly significant values were found for year,
handling (bruising), harvest date and cultivar, but none for nitrogen rate. While
significant interactions were found for year x harvest, year x cultivar, handling x
harvest, handling x cultivar and harvest x cultivar, all results were in the same
direction, with differences being in the magnitude of the reactions. Overall, Atlantic,
Marcy and Snowden had TGA levels of 20.95, 25.96 and 34.75 mg/100g, respectively.
Averaged over cultivars and treatments, the earlier harvest had higher TGA levels
(35.49) than the later harvest (18.95). The bruising treatment was very severe,
resulting in a 33.03 average compared to the non-damaged control average of 21.42.
