Abstract: This paper introduces the chemosterilization of Pinus armandi seeds with TBZ chemical,which has been tested as effectively operational for retarding the deteriora-tion of the seeds when sufficient ventilation is ensured under the conditions that the watercontent is 14%~19%and temperature from 6~26℃. The method is potential for thestorage of Pinus armandi seeds as raw material for food processing and of the seeds of othertree species.
