生长物质

The main reasons were that the algae and organism in the water decreased the ability of removing pollutants by coagulations, the algae which grown again in the open sedimentation tank weakened the removal effect of algae by coagulation; because of the accumulation of algae and algae toxin in the filtration tank, the concentration of algae toxin in the effluent increased; by the function of fluid chlorine, the algae and organisms after the filtration will release microalgae toxin and produce a lot of byproduct such as microalgae toxin, sobomyl and so on, meanwhile, the chlorination produce considerable halide and halo-acetic acid and other disinfection byproduct.

主要表现在藻类和溶解性有机物的存在降低了混凝去除污染物的能力；藻类在露天平流沉淀池中再生长，抵消了混凝除藻效果；藻类和藻毒素在滤池中积累，导致滤后藻毒素升高；穿透滤池的藻类和有机物在液氯作用下，释放微囊藻毒素、土臭素和二甲基异冰片等胞内物质，同时生成数量可观的卤代烃和卤乙酸等消毒副产物。

Result The results showed that tissue culture seedlings cultured with disinfection seeds and fresh fruit seeds had higher survival rates, which could reached above 75.0%. Taken Pingguoli and Xiangshuili for cions, Shanli without root for rootstock, the survival rate of graft seedlings had obvious difference. And Xiangshuili for cions had higher survival rates. Taken Xiangshuili for cions, Shanli and Xiangshuili for rootstock, the survival rate of graft seedlings with root had higher survival rates than that without root. Added hormone to the media could improve the survival rate of micro-grafting plants, in the medium of MS+BA 1.0 mg/L+IBA 0.3 mg/L, the survival rate reached 86.7%.

结果］种子消毒处理及鲜果取种组培苗的成活率均较高，达75.0%以上；以香水梨和苹果梨为接穗，无根山梨为砧木时的嫁接苗成活率有显著差异，其中以香水梨为接穗的成活率较高；以香水梨为接穗，山梨和香水梨为砧木时，带根的材料嫁接时的成活率都显著高于无根嫁接苗的成活率；此外，添加植物生长调节物质可以有效提高嫁接成活率，在培养基MS+BA 1.0 mg/L+IBA 0.3 mg/L中嫁接苗的成活率最高，达86.7%。
