氯化铝、氢氧化铝对马铃薯软腐菌侵染进程的不同影响

With Ecc (Erwinia carotovora subsp.carotovora), aluminum chloride, aluminum hydroxide treat potato. We use Evans blue dye to mensurate cell death rates. These results indicated abundant cell death in potato with aluminum chloride and Ecc+ aluminum chloride treat, respectively. Also implied this possibility of three value aluminum accelerate cell death. Cell death rates is lowest in aluminum hydroxide treat simple. Cell death rates with aluminum hydroxide + Ecc treat simple is lower than Ecc treat simple. That show advance action of aluminum hydroxide to defense disease. Aluminum chloride, Ecc+ aluminum chloride treat produce excessive H2O2 with DAB (diamino benzidine) dye and aluminum hydroxide，Ecc treat production is little. SDS-PAGE electrophoresis result indicate aluminum hydroxide treated obviously different from others. That show the different effect in interactional process by different value aluminum and plant and pathogenic bacteria.
