There are usually certain requirements for seed purity and quality of import vegetable seeds in every country especially seed-born disease examination. Black rot disease, caused by Xanthomonas campestris pv. campestri (Pammel) Dowson (Xcc), is one of the most deleteriuos diseases in crucifers. Besides filed management, the seed pre-sowing treatments are often applied for disease control. However, a decrease of germination percentage and seed vigor is also resulted at the same time. The objective of this research is to establish a safe protocol by heat or chemical treatments to diminish the black rot disease in cabbage without decreasing seed quality.十字花科蔬菜黑腐病熱處理藥劑處理種子發芽率crucifersblack rotheat treatmentchemical treatmentseed germination percentage
