Abstract
Cotoneaster multiflorus is a large deciduous, ornamental shrub, suitable for
landscape use. It has long arching branches and very abundant white flowers
followed by scarlet-red fruit. It is low-demanding species which can grow on
clay soils. As a drought tolerant species, it has potential to withstand the
effect of climate change. Generative propagation of this species is
difficult due to its combined embryo and seed coat dormancy. For that
reason, the aim of this study was to establish quick and effective method
for generative propagation of selected elite genotypes of C. multiflorus
that are growing in the Belgrade area. The seeds were collected in a public
green spaces in the park in Petlovo brdo, Belgrade, and after maceration,
the effect of different treatments was examined. These treatments included
soaking seeds in sulfuric acid at 96 % for 60 or 90 minutes, 5 months of
cold stratification at 3-5oS in perlite or without substrate (naked
stratification), and combinations of these treat?ments. The obtained results
showed that C. multiflorus requires the combination of sulfuric acid
pre?treatment and a cold stratification in perlite for germination. The
seeds treated with sulfuric acid followed by 5 months of naked
stratification didn?t germinate. The length of sulfuric acid treatment also
influenced germination rate and better results were achieved with seeds that
were soaked for 90 minutes in sulfuric acid compred to 60 minutes treatment.
However, the maximum germination percentage obtained in this research did
not exceed 40%, real ger?mination rate was 59%. It is necessary to perform
additional research in order to improve germination.
