“…35 The chlorophyll b was puried by silica gel column chromatography. [36][37][38] The following mobile phases were applied with the order of: 60% n-hexane, 16% cyclohexane, 10% ethyl acetate, 10% acetone, and 4% methanol. The elution order using this elution solvent system was bcarotene, chlorophyll b, and xanthophyll (from top to bottom).…”

Iron chlorine e6 (ICE6), also known as iron dihydroporphine, is a new type natural plant growth regulator, which can improve some crops growth. At present, the effects of ICE6 on rice are still unclear. Therefore, it is of great significance to study the effect of ICE6 on rice growth. In this study, the effect of seed treatment with ICE6 on rice germination and seedling growth was evaluated. Rice seeds were soaked with the gradient concentration and gradient time of ICE6, respectively, and then the germination rate, growth indexes and chlorophyll content of rice were determined. The results showed seed soaking with ICE6 could improve rice seed germination, promote seedling growth and increase the chlorophyll content in plants, exhibiting a better growth promoting effect. The optimum soaking condition was 100–200 mg/L (concentration) and 24–48 h (time). The field experiment further verified the growth regulating effect of ICE6 priming on rice seedlings. After seed priming with ICE6, seed vigor became higher, and the activities of α-amylase and protease in germinating seeds increased. The increase of seed vigor might be an important reason that ICE6 improved the germination and seedling growth. In addition, we also found ICE6 treatment could enhance the regeneration ability of seedlings. This work demonstrated the germination and growth promoting effect of ICE6 on rice, and revealed its application potential in rice production. This seed priming technique was of great promotional value in the field.

“…A further increase of Ce supplementation recovered Mg levels to that observed in the control sample. Magnesium cation coordinated with the porphyrin ring forms the chlorophyll active site [106,107]. It is also crucial for the activity of RuBisCO, and finally, the C3 carbon fixation pathway [108][109][110].…”

Cerium dioxide nanoparticles are pollutants of emerging concern. They are rarely immobilized in the environment. This study extends our work on Pisum sativum L. as a model plant, cultivated worldwide, and is well suited for investigating additive interactions induced by nanoceria. Hydroponic cultivation, which prompts accurate plant growth control and three levels of CeO2 supplementation, were applied, namely, 100, 200, and 500 mg (Ce)/L. Phytotoxicity was estimated by fresh weights and photosynthesis parameters. Additionally, Ce, Cu, Zn, Mn, Fe, Ca, and Mg contents were analyzed by high-resolution continuum source atomic absorption and inductively coupled plasma optical emission techniques. Analysis of variance has proved that CeO2 nanoparticles affected metals uptake. In the roots, it decreased for Cu, Zn, Mn, Fe, and Mg, while a reversed process was observed for Ca. The latter is absorbed more intensively, but translocation to above-ground parts is hampered. At the same time, nanoparticulate CeO2 reduced Cu, Zn, Mn, Fe, and Ca accumulation in pea shoots. The lowest Ce concentration boosted the photosynthesis rate, while the remaining treatments did not induce significant changes. Plant growth stimulation was observed only for the 100 mg/L. To our knowledge, this is the first study that demonstrates the effect of nanoceria on photosynthesis-related parameters in peas.
