Abstract
The present study was conducted at Horticultural Research Institute, Agricultural Research Center during 2021 and 2022 years on Taxodium distichum (L.) grown at two research stations, namely El-Nobaria and El-Gemmeiza. The aim of this study was to estimate which of the two provenances under study is better in terms of growth, biomass and wood properties of T. distichum (L.) at 22 years age. Determining the height along the tree is the most appropriate for manufacturing purposes. Mean values of merchantable height of T. distichum tree were 11.93 ± 0.23 and 13.05 ± 1.00 m at El-Nobaria and El-Gemmeiza Research Stations, respectively. Diameter at breast height (DBH) and merchantable volume were (35.11 ± 0.72 cm and 0.5687 ± 0.05 m3/tree) and (55.89 ± 6.12 cm and 1.0912 ± 0.11 m3/tree) at El-Nobaria and El-Gemmeiza Research Stations, respectively. The green and dry weight of T. distichum stem were (620.00 ± 80.00 and 313.75 ± 38.75 Kg/tree) and (1795.66 ± 185.44 and 823.58 ± 87.56 Kg/tree) at El-Nobaria and El- Gemmeiza Research Stations, respectively. Density, Modulus of rupture (MOR), Compressive strength (Cmax) and Hardness (R and T) of wood of T. distichum at DBH were (0.433g.cm-3, 68.180 MPa, 38.440 MPa, 3.403 N and 3.760 N) and (0.430 g.cm-3, 84.890 MPa, 34.070 MPa, 3.517 N and 3.790 N) at El-Nobaria and El-Gemmeiza Research Station, respectively. The results of this study indicated that, diameter at breast height and merchantable volume of T. distichumin clay soil (El- Gemmeiza Research Station) were more than once and a half time as compared to calcareous loamy soil (Al Nubaria Research Station). Basal area, the green and dry weight of stem and total above-ground biomass of T. distichum were more than twice as much in El-Gemmeiza than in El-Nobaria. The properties of wood up to 5 m above DBH were close, good and could be used for manufacturing purposes.
