Effect of wetwood and blue stain (Ceratocystis spp.) on the drying rate and fluid transport coefficients of poplar (P. nigra)

In this research, the effect of wetwood and blue stain on the drying rate and fluid transport coefficients of poplar (P. nigra) was evaluated. For this purpose, five boards with dimensions of 150 × 35 × 45 mm were cut from wet‌ wood, normal ‌wood and stained -wood areas of freshly cut lumbers in Tal...
