The Mathematics of Chlorophyll Photoexcitation [PDF]
arXivPhotosynthesis is a fundamental process for plants to produce energy and survive. It is a well known fact that the light reactions in photosynthesis are a significant part of the overall process, and are carried out by chlorophyll molecules. This paper outlines the quantum chemical and mathematical description concerning electronic state transitions ...

Chlorophyll breakdown and chlorophyll catabolites in leaves and fruit [PDF]
Photochemical & Photobiological Sciences, 2008 Chlorophyll metabolism probably is the most visible manifestation of life. Total annual turnover of chlorophyll has been estimated to involve more than 1000 million tons. Surprisingly, chlorophyll catabolism has remained an enigma until less than twenty years ago, when a colorless chlorophyll catabolite from senescent plant leaves was identified and ...

Satellite-derived global chlorophyll-a anomaly products
International Journal of Applied Earth Observations and Geoinformation, 2021 We describe our effort to produce the first-ever near-real-time (NRT) global daily chlorophyll-a (Chl-a) anomaly products that can be used to detect and identify algae blooms from satellite ocean color measurements such as those from the Visible Infrared

Identification of nutrient deficiency in bean plants by prompt chlorophyll fluorescence measurements and Artificial Neural Networks [PDF]
arXiv, 2019 The deficiency of macro (N, P, S, Ca, Mg and K) and micro (Zn, Cu, B, Mo, Cl, Mn and Fe) minerals has a major effect on plant development. The lack of some nutrient minerals especially of nitrogen, potassium, calcium, phosphorus and iron is a huge problem for agriculture and early warning and prevention of the problem will be very useful for agro ...

Biofuels, Bioproducts and Biorefining, EarlyView.Abstract The Moringa oleifera oil tree is commonly known as the ‘tree of life’ or the ‘miracle tree’ owing to its multiple benefits for humans. The different parts that make up this tree (leaves, seeds and bark) have been used to treat various ailments, diseases and wounds. However, in recent years this tree is being used by the scientific community to
