Abstract:
Olive is a perennial evergreen tree which has good
adaptability to poor environmental
conditions such as salt and drought resistance. In
recent years, there is a tendency to plant
olive trees in green spaces. Therefore, this study
was carried out to evaluate 15 olive
cultivars regarding growth habit, form, and texture
to recommend for landscape. Six-
year-old trees of 15 olive cultivars, which had bee
n planted in Isfahan University of
Technology (2000), were used in randomized block de
sign with 3 replications and some of
their vegetative characters were measured. A cluste
r analysis was done using seven
factors effective on tree texture, which divided cu
ltivars into 3 groups and a separate
genotype. Also, another cluster analysis done on th
e seven factors effective on tree form
classified olive cultivars in 3 groups. In short, M
anzanilla, Spain, and Amphisis cultivars
performed wide oval form and fine-medium coarse tex
ture, so they could be used as
background tree, screen, and group planting in gree
n spaces. Roughani, Mishen,
Valanolia, Gorgan, Kroneiki, Zard, and Sevillana cu
ltivars showed round form and
medium texture which could be used as specimen tree
to plant in lawn. Rashid cultivar
with long height, long oval form, and coarse textur
e is suitable as accent, screen, and
frame plant.
