Summary: A new method (max-kt method) is proposed to estimate aerosol radiative forcing (ARF) on photosynthetically active radiation (PAR) using only solar position and global irradiance measurements, which are readily available at many radiometric stations worldwide. The method is based on the parameterization of the relationship between clearness index (kt) and solar position. The ARF values obtained using the new method are comparable to those calculated by widely employed physical models, confirming its validity. The method is particularly useful when the inputs required by the physical models are difficult to obtain.

Summary: This study analyzes the effects of clouds on photosynthetically active radiation (PAR), including global PAR and its diffuse component. Through analyzing an 11-year dataset from a Mediterranean site, it is found that cloud cover, cloud frequency, liquid and ice content are related to the seasonal patterns of global PAR and diffuse PAR. The Cloud Radiative Effect (CRE) varies seasonally, and the diffuse fraction (k(PAR)) is related to cloud cover. Additionally, a relationship between k(PAR) and k(t) is found, allowing the estimation of k(PAR) from total solar irradiance measurements.

Summary: Pelargonidin glucosides represent important pigments in the food industry. This study compared the stability and antioxidant activity of different pelargonidin glycosides, with results showing that pelargonidin-3-O-glucoside and pelargonidin-3-O-rutinoside exhibited higher pH stability and were more stable in the presence of ferrous ions. Furthermore, reducing the number and molecular weight of glycosides increased the antioxidant activity while decreasing stability.

Summary: Understanding the effects of different processing methods, such as freeze drying, hot air drying, water boiling, steaming, and pickling, on the physical character, total polyphenols, anthocyanin profile, and antioxidant activity of red cabbage is important. The study found that different processing methods resulted in changes in color and texture, and pickling showed the highest values of total polyphenols and DPPH scavenge activity. Water boiling, steaming, and pickling decreased the loss of most anthocyanins in red cabbage compared to drying processes. The study suggested that drying significantly reduced the phytochemical content in red cabbage, and water boiling, steaming, and pickling were recommended methods for daily consumption, with steaming being the best way to retain anthocyanins.

Summary: This study quantitatively investigated the effects of aerosols on photosynthetically active radiation (PAR) during the winter haze period. The results showed that as the aerosol optical depth (AOD) increased, direct solar PAR irradiance decreased dramatically while diffuse downward irradiance increased weakly, leading to a significant surface aerosol radiative effect (ARE) in the PAR spectrum. Additionally, the attenuation of PAR was greater than other sub-bands in the shortwave spectrum as pollution increased. The efficiency of ARE in PAR was weakened during the severe-pollution period compared to the clear-air condition.

Summary: Photosynthetically Active Radiation (PAR) is crucial for plant growth, and a climate-based solar modelling method was found to be more practical in predicting PAR availability. The study showed that ray-tracing solar modelling can effectively predict PAR levels at specific positions, vertical farming activities can benefit from this. Additionally, the roof configuration in large-scale greenhouses has little impact on PAR availability, while the orientation of greenhouse affects the vertical arrangement of planting systems for vertical farming.

Summary: This study examined the changes in major fatty acids, vitamin E, and carotenoids in fibre flaxseed capsules during six mature stages. The levels of alpha-linolenic acid and oleic acid increased, while palmitic acid and linoleic acid decreased as the capsules matured. Gamma-tocopherol content increased progressively, while total carotenoids decreased continuously with lutein remaining the most abundant. The varied gene expression patterns may explain the changes in these components during flaxseed capsule maturation, suggesting their potential as a source of liposoluble compounds for food and nutraceutical applications.

Summary: This study investigated the carotenoid profiles and gene expression patterns in two genotypes of pomelo during early fruit development, finding that honey pomelo had higher carotenoid content, primarily lutein, alpha-carotene, and beta-carotene. The accumulation of carotenoids in honey pomelo was related to the transcriptional regulation of ZISO and LUT5, while in golden pomelo, the rate-limiting genes were PDS and ZDS. This research provides insights into the regulatory mechanisms of carotenoid accumulation and suggests directions for utilizing young pomelo fruits effectively.
