• light scattering (DLS), and scanning electron microscopy (SEM). The effect of ZnO NPs (70 nm) on R. sativus grown in coir was evaluated. The application of 1,000 mg/L of ZnO NPs resulted in a significant increase (p < 0.05) in soluble protein content, carbohydrates, chlorophyll a (Chl-a), chlorophyll b

• nutritional content of R. sativus. The positive correlation between chlorophyll content and photosynthetic rate allows the use of changes in total chlorophyll content as an indicator of plant health [38]. The increase in chlorophyll content observed in this study may be attributed to the increase in nutrients

In addition, a higher percentage of dry weight and chlorophyll formation over the germination period of 30 days were

In the region from 525 nm to 625 nm, the mallow dye spectrum reveals two small peaks at 536 nm and 608 nm. These peaks could serve to increase the charge-transfer

The characteristic golden-brown colour of the chrysophytes is based on the formation of the carotenoid zeaxanthin, a xanthophyll which masks the green colour of chlorophyll. They
