摘要
Abstract
[ Objective] Growth and development and SOD activity changes of hydroponic garlic were studied under different pH. [ Method] Hy-droponics was adopted to study the effect of different gradient of pH aqueous solution on growth and development of plants. The SOD activity was measured at different growth stages. The SOD precipitation was separated and purified by using acetone precipitation, the activity was de-termined by NBT photo reduction method. [Result] The best growth condition of hydroponic garlic was observed when the pH was 6. 0. Under the growth environment of pH 4. 5-5. 5, the SOD activity of garlic was relatively stable. With the gradual growth of germination, the SOD ac-tivity had rising tendency. SOD activity of garlic was relatively high in acid environment. [ Conclusion] The research can give guidance for hy-drophonic culturing garlic.关键词
