Light-nutrition coupling effect of degradable fluorescent carbon dots on lettuce

Abstract

The increasing application of carbon dots (CDs) inevitably lead to environmental leakage. To be environmentally friendly, degradable CDs will be the mainstream on agricultural application in the future. Our study...

Effects of multifunctional cerium-doped carbon dots on photosynthetic capacity and nutritional quality of lettuce

“…These results suggest that Ce-CDs can carry electrons and accelerate the electron transfer rate. Consequently, Ce-CDs can promote the formation of photosynthetic products by significantly increasing the ETR 29 and qP, which further improves the light energy utilization efficiency of PS II and enhances the photochemical energy conversion efficiency [Y(II)]. 63 Besides, Ce-CDs in chloroplasts can absorb UV light and emit blue fluorescence.…”

“…23 Many studies have shown that CDs have great potential in promoting plant growth, such as promoting growth and development, regulating plant photosynthesis, and improving plant stress resistance. 24–29 Kou et al have discovered that the activation of aquaporin-encoding genes by CDs can expedite seed germination, stimulate roots and hypocotyl elongation in seedlings, and enhance mineral element absorption and photosynthesis to improve both yield and nutritional quality in mature plants. 30 Tan et al have found that 100 mg L −1 N-CDs increased the chlorophyll a content by 12.68%, electron transport rate by 38.61%, and Rubisco activity by 60.61%, which significantly promoted the biomass accumulation (41.70%) and increased the nutrient content of lettuce.…”

Comparative analysis of chemically and green synthesized titanium dioxide nanoparticles for the regulation of photosynthesis in Lactuca sativa L.

“…Chloroplast suspensions were extracted as defined by Pan et al 24 and the chlorophyll concentration was 360 mg L −1 . Chloroplast suspensions were mixed with 10, 100, 250, and 500 mg L −1 TiO 2 NPs (1 : 1), respectively, and incubated in the dark for 2 h to obtain TiO 2 and chloroplast complexes (TiO 2 / Chl).…”

Nitrogen and Phosphorus Co-Doped Carbon Dots for the Growth Promotion of Water Spinach

“…Thus, its impact on the environment is negligible. Furthermore, CDs can accelerate the photosynthesis process in plants [18,19]. These advantages make CDs promising green fertilizers for plants.…”
