How Do Plant Growth Regulators Improve Photosynthetic Rate in Crops?

April 22, 2026 at 9:30 pm | Updated April 22, 2026 at 9:30 pm | 12 min read

Plant growth regulators (PGRs) can positively or negatively influence photosynthesis, depending on the chemical. PGRs alter photosynthesis by manipulating the leaf anatomy, morphology, and physiology. Physiological effects include a better stress response, and morphological alterations improve light infiltration in the canopy. Anatomically, PGRs improve chlorophyll content and the structure and functions of the photosynthetic apparatus.… Continue reading…

How Do Organic Fertilizers and Photosynthetic Rate Work Together?

Most research findings show that organic fertilizers improve the crop’s photosynthetic rate. The improvement occurs through increased photosynthetic efficiency, increased leaf number and area, and enhanced leaf chlorophyll content. Organic fertilizers enhance the soil’s nutrient status to support better plant growth and health, which increases crop photosynthetic rate. In many cases, organic fertilizers were more… Continue reading…

What Is Transpiration Efficiency and Why Does It Matter for Drought-Resistant Farming?

Transpiration efficiency is emerging as a crucial crop parameter to improve production in water-limited conditions. Restricting transpiration by crops is a vital strategy to increase productivity using less water. External factors like VPD, soil type, and nutrient status are also necessary to increase transpiration efficiency. Society must figure out ways to grow more food for… Continue reading…

How Does the Role of Senescence Affect Crop Productivity?

Senescence can determine and increase crop productivity. Selecting for cultivars with delayed senescence improves yield only in some species. Senescence increases plant phenotypic plasticity, helping it to adapt to abiotic stress. Senescence is a significant agricultural trait that affects crop growth, stress adaptation, yield, and postharvest storage. Plants are unusual as they can time senescence… Continue reading…

How Plant Science is Advancing Sustainability in Agriculture

Sustainability in Agriculture covers economic profits, environmental health, and social equity. Sustainable agriculture involves safeguarding humans, conserving natural resources, and improving the quality and quantity of profitable production throughout the food supply chain. Plant science aims to increase productivity with less inputs, chemicals, and water and more reliance on natural processes and onsite resources. Plant… Continue reading…

What is Senescence in Trees and Why Is It Important?

Senescence occurs at the cell, tissue, organs, and individual levels. Organ senescence is consequential in trees as it helps “recycle materials” within an individual tree to maintain function and productivity. Organ and whole tree senescence are also crucial for nutrient cycling, wildlife diversity, and forest productivity. Senescence is an integral part of all living organisms,… Continue reading…

Can Spectroscopy Predict Leaf Traits Across Ecosystems?

Yes, but with caveats. Leaf traits are used to understand plant growth, functional diversity, and ecosystem processes. Several traits spanning functional groups and geographies can be easily predicted using general models based on spectral data. However, all models cannot have global applications without validation, as the relationship between traits and spectral data is not the… Continue reading…
