摘要
本文讨论了唐菖蒲试管苗芽增殖过程中,不同植物生长调节剂、碳源、活性炭对芽增殖影响,试验结果表明0.5mg/LNAA和1mg/L的6-BA组合下,苗增殖效果好而且苗较壮,增殖倍数为5。用50g/L的市售白糖代替40g/L的纯蔗糖作为培养基的碳源是可行的,这样降低了配制培养基的成本,而且对试管苗的增殖和质量无影响。0.2%的活性炭,在30d内有利于试管苗株高的增加,但对芽的诱导无明显作用。
This paper discusses the effect on shoot proliferation growth of regulators, carbon source, activated carbon,test results show that the 0. 5mg/LNAA and l mg/L 6 -BA combination,shoot proliferation effect is good and the seedhng is strong,the proliferation multiples is 5.50g/L sugar instead of 40g/L pure sucrose as the carbon source of culture medium is feasible, thus reducing the cost of compounding culture medium, but had no effect on the proliferation and the quality of plantlets. 0.2% of activated carbon, in 30d test tube seed- ling plant height increased, but had no obvious effect on bud induction.
