Catalysis Today

On the other hand, previous studies have shown that infection of plants by Fusarium sp. results in a diminution of optimum quantum yield (Fv/Fm) and stomata conductance (gs) due to reduced water and nutrient uptake by roots (Ye et∼al. 2004).

Egyptian Journal of Biological Pest Control

On the other hand, the increased optimum quantum yield (Fv/Fm) and stomata conductance (gs) in cotton plants with respect to the control were in contrast with the report of Da Costa and Sharma (2016) who reported a decrease of Fv/Fm and gs as a result of nanoparticle exposure in Oryza sativa.

Egyptian Journal of Biological Pest Control

On the other hand, the transgenic insect-resistant cotton plants inoculated with F. solani, and treated with AgNPs from P. glandulosa and P. sericea, respectively, exhibited significant changes in the optimum quantum yield (Fv/Fm) values with respect to the control (Fig. 2b).

Egyptian Journal of Biological Pest Control

In this sense, our study showed that the optimum quantum yield (Fv/Fm) and stomata conductance (gs) was significantly increased in cotton plants treated with Ag nanoparticles from P. glandulosa and P. sericea, suggesting that the use of nanoparticles prevented the F. solani invasion in the roots favoring water transport in the cotton plants.

Expert writing Tips

Best practice

When discussing photosynthetic efficiency in plants, use "optimum quantum yield (Fv/Fm)" to precisely indicate the measurement of photosystem II efficiency, especially in scientific reports.

Common error

Avoid using "optimum quantum yield" loosely to mean 'a good' quantum yield. The term implies a scientifically determined peak efficiency under specific conditions, not just any favorable result.

Linguistic Context

The phrase "optimum quantum yield" functions as a technical term, primarily in scientific contexts. It specifies the highest efficiency achievable in a quantum process, particularly in photosynthesis as shown by Ludwig. This makes it a key concept in fields like plant physiology and photochemistry.

FAQs

How is "optimum quantum yield" measured in plants?

In plants, "optimum quantum yield" (Fv/Fm) is typically measured using a chlorophyll fluorometer. This measurement assesses the maximum potential efficiency of photosystem II (PSII), indicating the plant's ability to convert light energy into chemical energy during photosynthesis.

What factors can affect the "optimum quantum yield"?

Various factors can affect the "optimum quantum yield", including light intensity, temperature, water availability, nutrient levels, and the presence of stressors such as pollutants or pathogens. Changes in these conditions can either increase or decrease the efficiency of photosynthetic processes.

How does the "optimum quantum yield" relate to plant health?

The "optimum quantum yield" serves as a vital indicator of plant health. A high Fv/Fm ratio typically signifies that the plant is healthy and efficiently using light energy for photosynthesis, while a lower ratio may suggest stress or damage to the photosynthetic apparatus.

Are there alternatives to using "optimum quantum yield"?

While "optimum quantum yield" is a precise scientific term, you can use alternatives like "peak quantum yield" or "maximum quantum yield" depending on the specific context and desired level of formality. However, in scientific writing, "optimum quantum yield" is generally preferred for its accuracy.
