Effect of water temperature and prey concentrations on initial development of Lophiosilurus alexandri Steindachner, 1876 (Siluriformes: Pseudopimelodidae), a freshwater fish

Neotropical Ichthyology
The aim of this study was to investigate the effects of water temperature and prey concentrations (Artemia nauplii) on the initial development of Lophiosilurus alexandri larvae. The experiment was conducted using a 4 x 2 factorial design, with four water

Nondestructive diagnosis of mineral deficiencies in wheat leaves by one- or two-shot saturation pulse measurement of chlorophyll fluorescence and P700+ absorbance with machine learning

Smart Agricultural Technology
We hydroponically cultivated wheat and subjected them to mineral deficiency by a week-long exposure to Hoagland's solution minus one essential mineral.

Differences in gas exchange, chlorophyll fluorescence, and modulated reflection of light at 820 nm between two rhododendron cultivars under aluminum stress conditions.

PLoS ONE
Aluminum (Al) toxicity is an important factor restricting the normal growth of plants in acidic soil. Rhododendron (Ericaceae) can grow relatively well in acidic soil. To uncover the adaptive mechanisms of photosynthesis under Al stress, the influence of

Exploration of the Effects of Cadmium Stress on Photosynthesis in Oenanthe javanica (Blume) DC.

Toxics
Cadmium ion (Cd2+) stress is a major abiotic stressor affecting plant photosynthesis. However, the impact of sustained high-concentration Cd stress on the photosynthetic electron transport chain of aquatic plants is currently unclear.

Role of Plastocyanin in response to photosynthetic electron transport in Solanum nigrum under Cd stress

Plant Stress
Plastocyanin (PC), an essential electron carrier located between the cytochrome b6f (cytb6f) complex and PSI in photosynthetic electron transport, remains inadequately understood regarding its regulatory role in electron transfer under heavy metal stress.

Light Pretreatment Improves the Heat Tolerance of Pea Plants’ Photosynthetic Apparatus

Stresses
This study investigated the impact of the pretreatment of pea plants (Pisum sativum L. Ran 1) for five days by three times higher light intensity (360 μmol m−2 s−1) than the intensity for their cultivation (120 μmol m−2 s−1) on the photosynthetic ...
