Wartosc dekoracyjna, uzytkowa i przydatnosc do nasadzen miejskich odmian jabloni ozdobnych Evaluation of the decorative and consumption values of crabapple cultivars and their usefulness for urban development
Crabapples are well known ornam
ental trees. The magnificent flowering and
abundant, colorful fruiting are the main features that have made these trees so popular
with the public. From over 900 species, hybrids and cultivars known throughout the world
it is very difficult to make the rig
ht choice and find the proper tree for a given public area,
private garden, or street planting. Although hundreds of crabapples have been named, not
many of them have been described and marketed. The majority still remain unknown and
unavailable in Poland.
In this article, based on the available literature and author’s own
observations, an evaluation of the decorative value of
176
cultivars of crabapple is
presented.
Three
of them scored in this research excellent marks of 15 points, which
means that these
trees are suitable for any landscaping needs.
Three
cultivars were
evaluated at the lowest level of 7 points or less, and their propagation and cultivation
should be discontinued mostly because of their high susceptibility to scab. Although
flowering craba
pples need very little care, they have one serious problem
–
leaf diseases,
with the main and often noted apple scab. This is the main reason why so many of the
crabapples in the presented evaluation which scored 7
-
9 points should be planted only in
botani
cal and dendrological collections to maintain gene diversity and/or for further
hybridization programs.
