“…Previous reports have demonstrated that nutrient deficiency (N, P) can severely and negatively influence duckweed biomass yield (Reid and Bieleski, 1970;Zhao et al, 2015). Guo et al (2020) reported a dry weight of 5.6 g/m 2 /day under NL for the duckweed Landoltia punctata 0202, which is even lower than the dry weight measured under similar conditions here. Similarly, Liu et al (2018) measured a dry weight of 5.6 g/m 2 /day after 14 days of cultivation for L. punctata 0202 in distilled water.…”

“…The currently highest reported starch content for duckweed was achieved after 9 days of cultivation in NL conditions in the presence of sucrose, reaching 60.0% of the total dry weight (Yu et al, 2017), a value that is comparable to the results with NL conditions here. Guo et al (2020) also reported that duckweed can quickly accumulate starch up to 52.4% under NL. Similarly, by transferring S. polyrhiza from nutrient-replete conditions to tap water for 5 days, the starch content increased from about 20.0% to 45.8% of total dry weight (Cheng and Stomp, 2009).…”

“…More importantly, the nitrogen use efficiency of duckweed reaches 61.3 ± 1.8 kg biomass/kg N, which is higher than most cereals and trees under N‐sufficient conditions. Under N‐insufficient conditions, the powerful and efficient autophagy and ubiquitin proteasome system activate the remobilization and recycling of endogenous N to support duckweed growth and starch accumulation (Guo et al., 2020). The effects of phytohormones on biomass production and starch accumulation have been systematically studied.…”
