Abstract:
Morphology and nutrient of leaf in Quercus castaneifolia
(C.A.Meyer) seedlings in competition with blackberry (Rubus fructicosus
L.) was investigated in an intervened lowland forest of Noor city, north
of Iran. The research was conducted as factorial experiment in three replications.
For this purpose, seedlings of small (3 mm) and large (4 mm) in collar
diameter (CD) were sown in two treatments (i) covered with Rubus
and (ii) moved from Rubus in 0.5 m radius around the Quercus
seedling, replicated three times. In the end of the first growing season,
leaf samples were randomly taken from 9 seedlings in each treatment in
order to determine leaf number, leaf dry matter, leaf area, growth flush
number, apical shoot growth and concentrations of leaf nutrient (N, P,
Mg and Ca). Leaf dry matter did not differ among the treatments. Leaf
number and leaf area were greatest with large CD seedlings growing in
moved Rubus area. The greatest apical shoot growth was observed
with large CD seedlings growing in full Rubus area. The same as
growth flush number, concentration of P, N and Mg was greatest with small
CD seedlings in moved Rubus area. From this research it can be
deduced that the seedlings growing in moved Rubus area produce
greater plant biomass and mineral nutrient matter.
