| Abstract: | Swellings on trunks and branches commonly occur in spring and seriously harm growth of grafting plants of Chinese chestnut.Some field investigations and the tests of pathogene culture and inoculation about swellings on rinds of Castanea mollissima indicate that the symptom is caused by poor drainage in forest lands,poor coalescence graft unions and damage of Scolytus which occured most frequently among the three. |
