what is optimum temperature for photosynthesis - 352898 ..

I would repeat the
experiment with the above improvements but use the following
temperatures instead:

41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52 (oC)

If I wanted I could also find a more accurate optimum temperature by
using a small range of results at small intervals, for example if the
highest reading was at 47 oC, I could then measure the rates of
respiration at the following temperatures:

46.5, 46.6, 46.7, 46.8, 46.9, 47.0, 47.1, 47.2, 47.3, 47.4, 47.5 (oC)

This would give me a more accurate optimum temperature, as the optimum
temperature is only as accurate as the temperature intervals are
small.

Differentparts of the same plant may also have different optimum temperatures for growth.

This diagram shows what I would
use:


Extended experiment:

I could repeat the experiment with the aim of find the optimum
temperature for anaerobic respiration in yeast.

Sorghum optimum temp for root growth is at 35˚С, ..

Therefore, optimum day temperature forgrowth generally decrease as solar radiant energy decreases.

Coco provides excellent insulation. This means that coco isn’t prone to overheating, due to excessive ambient air temperatures, as many other mediums (making it ideal for warm geographic zones). This is because water tends to make its way into the lower regions of the coco coir, leaving the top layer relatively drier. Because of this, heat needs to penetrate a drier top layer of coco coir before reaching the watered areas of the media. As water is a great conductor of energy (in the form of heat) the lower wet area being protected by a drier surface helps keep the lower areas of the media, where the bulk of the root mass is found, cooler. As media temperature and oxygen levels (air porosity) are interrelated (the warmer the media the less oxygen) this insulation plays an important role in promoting root health and vigour.

Put simply a plant can only use so much oxygen that is available to the rhizosphere (roots). This figure tends to be asserted at approximately 25 -30% oxygen availability (air porosity). Give a plant more oxygen to the roots than this and it can’t use it – much as the same way that a plant can only use so much atmospheric CO2 (i.e. when enriching a growroom with CO2 you eventually reach a limit set by how fast the machinery of photosynthesis -the chloroplast- can tick over and any additional CO2 you inject into the air, at this point, will go to waste). Put simply (at least according to the science), airoponics offers no real benefits over other growing systems and, in fact, I would argue is less effective than run-to-waste methods of growing. This is because airoponics recycles nutrient, which over time becomes depleted and suffers pH fluctuations, while run-to-waste methodology provides fresh (new) feed/nutrient time after time after time. This offers distinct benefits over any form of recycling system.

What is the optimum temperature for photosynthesis?

Photosynthesis is highly sensitive to high temperature stress and is often inhibited before other cell functions are impaired [4] .

This means that if all your other variables are not optimal (light, fertilizer, temp/humidity, pH, etc.) you will not achieve the benefits of increased CO2 levels.Now that we know the benefit of adding CO2 to your indoor growing environment, one thing to note is that CO2 enrichment will not be as effective if your grow area is not sealed since it will be exhausted before the plants can use it.

Recent work has shown that a temperature drop or rise for 2-3hours at the beginning or end of the light period has a strong affect on internode elongation.

Several experiments have revealed that Photosynthesis does have an optimum temperature range, ..

As temperature increases, the rate of photosynthesis increases more and more steeply until the optimum temperature is reached. If temperature keeps increasing above the optimum temperature then photosynthesis starts to decrease very rapidly.

Optimum temperature is required for maximum dry matter accumulation

Therefore, temperature cannot be considered inisolation and any statement about an optimum temperature for growth of a given crop cannot bemade.
