| Özet |
| The influence of stand age on litter quality, decomposition rate and nutrient release was examined in pure stands of Kazdagi fir (Abies nordmanniana subsp. equi-trojani [Steven] Spach) differing in age (Fir 38, Fir 60, Fir 90 and Fir 100 years). The needle litters were collected and analysed for initial total carbon, cellulose, hemicellulose, lignin and nutrient concentrations (N, P, K, Ca, S, Mg, Mn and Fe). Initial litter quality parameters varied significantly among the four stand age classes. The Fir 60 and Fir 100 stands had higher total C than the Fir 38 and Fir 90 stands, while the Fir 38 and Fir 100 stands had higher N than the Fir 60 and Fir 90 stands. Mean cellulose and hemicellulose concentrations were highest in the Fir 90 stand, while mean lignin concentration was highest in the Fir 38 stand. Fir 90 stand showed the highest ratios of C/N and Lignin/N. In general, the older fir stands showed higher Ca, Mg and K concentrations and lower P and S concentrations than the younger stands. The litter, however, showed higher a Mn concentration under the Fir 60. Mean Fe concentration was highest under the Fir 38 stand and lowest under the Fir 60 stand. Litter decomposition was studied in the field using the litterbag technique. The litterbags were placed on the soil under each stand age class and sampled every 6 months for 2 years. The interaction of stand age and time on the mass loss was significant (p< 0.01). The repeated measures ANOVA showed that the main effect of time on the mass loss was also significant (p< 0.001). Needle litters under Fir 100 and Fir 60 stands decomposed faster than the needle litters under Fir 90 and Fir 38 stands. The … |
