由于其在不同栽培中的高生物量和淀粉产量，Landoltia punctata 被认为是一种潜在的生物能源作物。已知钴和镍会诱导浮萍中淀粉的积累。监测了不同钴、镍浓度下的生长速率、净光合速率、总叶绿素含量、Rubisco活性、Co2+和Ni2+含量、抗氧化酶活性、淀粉含量和相关酶活性。结果表明 Co2+ 和 Ni2+ (
Landoltia punctata has been considered as a potential bioenergy crop due to its high biomass and starch yields in different cultivations. Cobalt and nickel are known to induce starch accumulation in duckweed. We monitored the growth rate, net photosynthesis rate, total chlorophyll content, Rubisco activity, Co2+ and Ni2+ contents, activity of antioxidant enzymes, starch content and activity of related enzymes under various concentrations of cobalt and nickel. The results indicate that Co2+ and Ni2+ (
