“…Hence, the highest chlorophyll-a content in A. falcatus was obtained on day 15 at 702 lux which was the lowest light intensity employed in this study. Although light is important for chlorophyll synthesis, very high light intensities inhibit chloroplast development [43,44]. On the whole, the chlorophyll-a contents of A. falcatus were significantly higher (P < 0.05) than those of C. sorokiniana under all the light intensities investigated.…”

Microalgae biomass and their products are invaluable bio-resources with numerous applications in food, feed, pharmacy, cosmetics, and environments. The effects of light intensities on biomass, chlorophyll-a, and total carotenoid production by Chlorella sorokiniana and Ankistrodesmus falcatus were studied in Bold's Basal Medium (BBM) and Poultry Medium (PM) as the growth media. The growth of C. sorokiniana and A. falcatus increased with increase in light intensity in PM and was inhibited at 1786 lux in C. sorokiniana in BBM. PM supported higher biomass production by C. sorokiniana than BBM while it was the reverse for A. falcatus. A. falcatus produced higher (P ≤ 0.05) concentrations of chlorophyll-a than C. sorokiniana in both media. The highest carotenoid concentration of 11.84 mg/g-biomass was accumulated by C. sorokiniana in PM as against 7.027 mg/g-biomass obtained in BBM. On the other hand, the highest carotenoid concentration of 7.633 mg/g-biomass was accumulated by A. falcatus in BBM as against 4.299 mg/g-biomass obtained in PM. It is interesting to note in the present study that a cheap medium such as PM supported higher biomass and carotenoid production by C. sorokiniana than BBM.

“…CaCl 2 can effectively increase PAL activity and anthocyanin content in the pedicel (Avila-Rostant et al, 2010). It is proved that Ca 2+ can overcome the decrease in photosynthate (mainly sugars) accumulation and PAL activity caused by insufficient sunlight (Wang, 1999;Wang et al, 2018) and can provide sufficient precursors and pathways for the synthesis of anthocyanins, thereby increasing anthocyanin content (Yang et al, 2015). The use of exogenous Ca 2+ derived from oyster shell waste not only alleviates the environmental pollution caused by unused oyster shells but also offers a solution for improving the cultivation of A. andraeanum.…”

Anthurium andraeanum Lind. is an economically important potted and fresh-cut flower species. However, reduced anthocyanin content under shaded cultivation impacts the color of the spathe, which has negative implications for the marketability of A. andraeanum. Thus, the present study evaluates the use of oyster shell supplementation to the cultivation medium for improving anthocyanin content. Appropriate calcium (Ca) can improve the activity of phenylalanine ammonia lyase (PAL), and PAL activity is positively correlated with anthocyanin content; nitrogen (N) and phosphorus (P) nutrients are closely related to anthocyanin synthesis. N and P nutrients and Ca can alleviate the color symptoms of A. andraeanum when anthocyanin content decreases under weak light (under 220 μmol·m−2·s−1). Microdissolution of calcium carbonate, the main component of oyster shell, can provide better exogenous Ca and adsorb slow-release N and P. Selecting appropriate oyster shell fragments will be the key to A. andraeanum experimental cultivation under low light conditions. Using regression models and response surface methodology (RSM), the relationships between oyster shell fragments and anthocyanin content are promulgated. The main findings indicated that the Ca released from 286-mg oyster shell fragments at pH 5.5 significantly increased the activity of PAL in the pedicel under weak light within 8 hours. At pH 5.9, 375-mg oyster shell fragments could significantly adsorb N and P nutrients within 4 to 14 hours. In conclusion, 286 to 375 mg oyster shell fragments at pH 5.5 to 5.9 could stabilize slow-release fertilizer source and significantly increase anthocyanin content in A. andraeanum spathe.

“…The high diversity of color in chimeric plants is due to the changes of spatial distribution of pigment types, concentrations and proportions in the leaves. These changes are the result of the interaction between genetic and environmental factors [1][2][3]. Climate, soil nutrients, and water have long been understood to be primary factors influencing plant growth, and the light intensity is an important environmental factor [4,5].…”

Ananas comosus var. bracteatus is an important ornamental plant because of its green/white chimeric leaves. The accumulation of anthocyanin makes the leaf turn to red especially in the marginal part. However, the red fades away in summer and winter. Light intensity is one of the most important factors affecting leaf color along the seasons. In order to understand the effects of light intensity on the growth and coloration of the chimeric leaves, Ananas comosus var. bracteatus was grown under full sunlight, 50% shade and 75% shade for 75 days to evaluate the concentration of pigments, the color parameters (values L Ã , a Ã , b Ã ) and the morpho-anatomical variations of chimeric leaves. The results showed that a high irradiance was beneficial to keep the chimeric leaves red. However, prolonged exposure to high irradiance caused a damage, some of the leaves wrinkled and even burned. Shading instead decreased the concentration of anthocyanin and increased the concentration of chlorophyll, especially in the white marginal part of the leaves. Numerous chloroplasts were observed in the mesophyll cells of the white marginal part of the chimeric leaves under shading for 75 days. The increase in chlorophyll concentration resulted in a better growth of plants. In order to balance the growth and coloration of the leaves, approximately 50% shade is suggested to be the optimum light irradiance condition for Ananas comosus var. bracteatus in summer.
