DEVELOPMENT AND AGEING
IN FOREST TREES
20-24 September, 2000
Please visit the Workshop web page at:
What controls tree development and ageing? what is the relative role of
internal and external factors? At the tissue level, recent advances
have demonstrated in detail that development and senescence both result
from the interaction of genetic and environmental controls, involving
differential gene expression and activation. At the tree level, a
shift in hormonal patterns, possibly of endogenous genetic origin, has
been found to trigger the process of maturation, which strongly affects
the structure, function and growth of the plant and initiates the
diversion of resources from vegetative to reproductive growth. Also at
the tree and population level, exogenous factors have been proposed to
control the developmental pattern of rise and decline of primary
productivity with age. A lively discussion has been going on for several
years on what could be the ecological determinants of the age-related
decline in forest productivity. Several theories have been proposed to
explain this phenomenon, variously suggesting nutrient or hydraulic
limitations, increased respiration and shifts in biomass allocation as
possible mechanisms, but to date there is no definitive evidence to
support any of them as a universal mechanism.
Ageing and maturation are generally thought to be intimately interwined
albeith distinct processes. Eventually, what are the implications of
development and ageing for the response of tissues and plants to their
biotic and abiotic environment?
Because of the variety of processes involved in tree development and
maturation, definite answers often result elusive, requiring a
comprehensive and holistic approach that takes both endogenous and
external factors into account.
The aim of the workshop is therefore to bring together experts of
different background and expertise to discuss these processes of central
relevance both to plant biology and to forest ecology moving from
different perspectives. An interdisciplinary workshop on this issue
that brings together foresters, ecologists and biologists seems most
appropriate and relevant to the aims of the EUROSILVA Action.
TREE PHYSIOLOGY SPECIAL ISSUE
Tree Physiology, a well-known refereed journal, has agreed to draw from
the Workshop a special issue on 'Development and ageing of forest
trees'. All the authors of accepted oral presentations are invited to
contribute, although only those papers that are deemed acceptable by the
reviewers and editor will be published in the special issue of Tree
Papers should be prepared in accordance with Tree Physiology's guide for
contributors and submitted (original plus three copies) to the workshop
local organisers no later than 31 October, 2000. The length of the
manuscript should not exceed 8 pages (about 8000 words, including
references). The manuscript should also be provided as a digital file (a
PDF file, if possible, otherwise an MS Word or Word Perfect file, on an
IBM-format floppy disk, zip disk or CD-ROM). The file should be named
after the corresponding author, e.g. smith.doc, and contain all
components of the article including tables, figures and figure captions.

A field excursion will be organized on Sunday 24 September, 2000. Local
foresters and ecologists will take us through the Chianti region to the
oak and beech stands of Montagnola Senese and of the Parco Naturale
della Val d'Orcia, close to the Monte Amiata massif. We will then move
on to visit the medieval abbey of Sant'Antimo, founded by Charlemagne in
871, and the medieval village of Montalcino, home to one of the most
famous Italian wines, the Brunello. A guided tour of the cellars in one
of the most interesting wineries in the area, complete with a wine
tasting experience, will end the day. Please note that an additional
EUR 50 will be charged for the field excursion.
The Organizing Secretariat Enic has reserved a sufficient number of

and Milan airports with connections to all international destinations.
There is also a shuttle service with hourly departures (price Lit.
6.000, tickets can be purchased at the airport espresso bar or on
board). Taxis are available on the "Arrivals" side of the airport, the
average fair to downtown Florence is Lit. 30.000. The Pisa airport (80
km from Florence) is linked to Florence by trains leaving every hour.
By train: Florence has excellent rail connections to the major Italian
and European cities via the Eurostar trains. The Santa Maria Novella
Railroad Station is in the center of the city.
By car - Parking: You can access the city by car although the historic
center is closed to private traffic. You can get to your hotel by
showing the booking voucher, and then you can park in the hotel's nearby
The main underground public parking facilities (hourly or daily rates)
are located under the Santa Maria Novella Railroad Station, under the
Parterre in Piazza della Libert and at the Fortezza da Basso.
Taxis: The minimum fare for a cab ride in Florence is Lit. 7.000. The
radio cab numbers are: 055 4798; 055 4242 and 055 4390. There are cab
