National Peach Varieties and Growing Traditions


The Natural History of PLINY
mentions an enigmatic tree
species referred to as ’Tuberes’.
This tree was introduced into Italy
from Syria in the times of the
Emperor AUGUSTUS. It is
interesting to note that the tree
’Tuberes’ already existed in the
times of NERO which meant
nectarine: As a garden plant it was
first encountered by PLINY. The
scientific species name Persica
vulgaris      (Prunus       persica)
suggests that the region of origin
of the peach would be Persia but
in fact the latter is only the
secondary gene centre of the
peach. Perhaps, the Roman
legionaries were the first in                      Picture 1: Parasztbarack (Csongrád, 2006)
Europe to taste its fruit. Thus, the

hand, it is possible that in the

peaches are gifts only of the 18th
and 19th centuries.
    Having seen the historical
background, it seems advisable to
consider, one by one, the finds of
fruit stones and the national
written sources as it is not possible
to rule out with certainty that the
peach was introduced into
Pannonia either by Celtics from
the West or brought into the               Picture 2: Fügebarack, alias Peento (Csemô, 1997)

    It is worthwhile to have a look
at the Europe of the 15th–16th
centuries even if peach production
can already be encountered in the
8th–9th centuries. Accordingly,
historical sources make mention
of peaches in England, Holland
and in areas north of Paris,
situated, in particular, in sheltered
gardens and along south-facing
walls of houses. Later (e.g. in
England) frost tolerant varieties       Picture 4: Cézanne: Fruit bowl with peaches

VIII started experiments with
peach growing again, almost from
the beginning. Over the following
centuries, it was again the French
that excelled with peaches.
SERRES (1604) described already
as many as 12 peach varieties
while LECTIER (1628) 27 ones
and 38 varieties were presented by
MERLET (1667) in his book.
    In the 16th century, according
to GESNER, two peach varieties
of Hungarian origin were growing
in the garden of WOYSSEL in
Wroclaw: ’Vérbarack’ (Picture 5)
and ’Woyssel sárga duráncija’.
These were also described and
classified by BAUHIN in his
botanical work (Pinax theatri
botanici). In his Fructologia

Grassland utilization by draft horse


Farming on grassland has been
going on since the Hungarians
settled in the Carpathian Basin.
    The role of grass as a natural
source of energy has changed over
the course history; it has
decreased. Recently 11% of the
country and 18% of the
agricultural land was covered by
grass. This means altogether 1015
million ha grassland. The vast
majority of this is poor-medium
quality, which is suitable for
extensive way of grazing.
