| Abstract: | Studies on brown spot of schima superba seedling were carried out during 1984-1986. The causal pathogen of this disease is indentified as Defldrophoma sp. , its pyc-nidium is 86.6-198.8×49.5-123.2um in diameter, conidium is 6.4-7.5 ×2.5-3.0 um in diameter, colourless, elliptic conidiaphores are branched.
Rusults from experiments showed that for mycelial growth Potato dextros agar, optimum medium pH value is 6 , and optimum relative humidity 93%. For conidia germination is 5 % dextroses, the optimum pH is 6 , and the optimum tempercoture ranged 25-30℃. |
