fruits and vegetables. Dr. Eaves vast
knowledge of CA storage was acknowledged
at the 1970 International
Horticultural Congress in Tel Aviv, Israel,
where he was invited to give the keynote
postharvest lecture.
Dr. Eaves made other postharvest contributions.
In 1967, he showed that ethylene
gas can be removed from the storage
atmosphere using potassium permanganate
and, in 1968, he demonstrated
that the undesirable and dangerous
greening of potatoes can be stopped with

the addition of CO 2. The effect of mineral
nutrition on postharvest quality also
caught his interest. In the mid-1950’s he
was the first person to report that fruit
acidity can be maintained or increased by
increasing K content and, in 1964, he
showed that increasing calcium content
of fruit improves firmness and reduces
decay.
In order to foster horticultural research
and scholarship, Dr. Eaves initiated and
continues to financially support the major
research award of the Canadian Society
for Horticultural Science. It is the
Macoun-Hill Award, given annually to the
authors of the best horticultural research
paper in the Canadian Journal of Plant
Science. In addition, he has endowed
financial support for both graduate and
undergraduate scholarships in conservation
studies at the Nova Scotia
Agricultural College.

The ISHS Working Group on Modeling in Fruit Research convened in Davis,
California, USA 15-18 July 2001 for its sixth International Symposium entitled
Modeling in Fruit Research and Orchard Management. The Convenor of
the very successful symposium was Dr. Ted DeJong, of the University of
California, Davis. Approximately 60 participants presented papers and contributed
to the many discussions.
The symposium opened with a very
stimulating paper and demonstration of
the new Lindenmayer Systems (L-Sys-
tems) modeling software by Dr. P.
Prusinkiewicz, from the University of
Calgary, Canada. The software is
extremely concise and allows the combi-

and physiological processes to be simulated
together. A presentation by Allen,
DeJong and Prusinkiewicz showed how
the software was used to model carbon
transport and partitioning in the peach
tree.
The symposium presentations covered
modeling in the areas of fruit crop phenology;
crop light interception, carbon
production and dry matter partitioning;
crop water use; effects of environment,
pest and cultural practices on growth, gas
exchange, fruit development and produc-
