Influence of gap size and development stages on the silvicultural characteristics of oriental beech (Fagus orientalis Lipsky) regeneration
We studied 11 gaps covered with beech saplings (< 1.30 m tall) in a reserve compartment (compartment 139, district one, Langa forest, watershed 36: Kazemrood) of the Caspian beech forest in N Iran. Two transects, each 2 m wide, were laid along the longest (N-S) and shortest (E-W) axis of each g...

| 總結: | We studied 11 gaps covered with beech saplings (< 1.30 m tall) in a reserve compartment (compartment 139,
district one, Langa forest, watershed 36: Kazemrood) of the Caspian beech forest in N Iran. Two transects,
each 2 m wide, were laid along the longest (N-S) and shortest (E-W) axis of each gap. Five micro sample
plots, each 4 m2, were established: one at the center, and one at each corner. Qualitative and quantitative
characteristics of saplings with a diameter at breast height less than 7.5 cm were examined in the micro
sample plots. Analysis of variance (ANOVA) and Kruskal-Wallis test were performed using SPSS software
for quantitative characteristics, and chi-square test for qualitative characteristics. Results indicated that
medium-sized (200-500 m2) gaps promote the growth of oriental beech saplings of desirable silvicultural
forms during decay and initial stages. |
