Abstract:
The monitoring of new
grapevine varieties with superior
agrobiological and technological
characteristics, in relation to the evolution of
the climatic factors, represents an important
and continuous objective of the worldwide
viticultural research and breeding programs.
Observations and determinations of the
current study were performed on 11 new table
grapes varieties created in Romania, growing
in the Ampelographic collection of the
University of Life Sciences Iasi, north-eastern
area of Romania. The grapevine varieties
were evaluated under the morpho-structural
aspect, regarding the leaf area, the average
weight of the grapes, the number and weight
of the berries, rachis weight, the number and
weight of the seeds, the weight of the skin and
pulp, calculating the main technological
indices. From a biochemical point of view,
the content of photosynthetic pigments in
leaves, the concentration of soluble dry solids
and titratable acidity of the grapes were
determined in the climatic condition of the
Copou - Iasi vineyard. Therefore, the
monitoring of genetic resources provides
useful data for grape producers and
researchers regarding the integration of new
table grape varieties into the viticultural
ecosystems, evaluating their yield and quality
in correlation with the evolution and
influence of the climatic factors.
