Effect of high consentrated dissolved oxygen on the plant ...

In this study, the effect of high concentrated dissolved oxygen (20-30mg/l) on the lettuce plant growth in a deep hydroponic culture under a low greenhouse temperature is investigated using an oxygen enricher (Ehime Sanso, OD110) and a pure high-pressured oxygen gas (95% O2).

Effect of oxygen concentration on plant growth ...

Mar 01, 1997 · Tomato plants were grown under either a high (11-14%; Air treatment), a moderate (5.8-7%; Control) or a low (0.8-1.5%; Nitrogen treatment) oxygen concentration and inoculated or not with the pathogen. The high oxygen treatment resulted in a marked increase in plant growth, as measured by shoot and root weights.

The Effect of Oxygen Concentration ... - Wiley Online Library

The inhibition increases with oxygen concentration and is about 30% in an atmosphere of 21% O 2 and 0.03% Co. 2. Undoubtedly, therefore, oxygen in normal air exerts a strong inhibitory effect on photosynthetic Co 2 fixation of land plants under natural conditions. The inhibitory effect of oxygen is rapidly produced and fully reversible.

Leghemoglobin - Wikipedia

Leghemoglobin buffers the concentration of free oxygen in the cytoplasm of infected plant cells to ensure the proper function of root nodules. Leghemoglobin has a high affinity for oxygen (K m ~ 0.01 μM), about ten times higher than the β chain of human hemoglobin. This maintains an oxygen concentration that is low enough to allow nitrogenase ...

Plant Growth and the Role Oxygen Plays

How Oxygen Affects Plant Growth. At the center of every new plant growth cell is an atom of carbon, which the plant absorbs from carbon dioxide in the immediately surrounding air.As CO2 is used for its carbon, water vapor and Oxygen are released from the plant stomata as waste.

Effect of oxygen and carbon dioxide on ... - SpringerLink

High concentrations of carbon dioxide inhibited growth in the rotating drum fermentor at non-limiting levels of oxygen. It is concluded that aeration and heat removal are both essential aspects of optimization of large-scale solid-substrate bioreactors with Rh. oligosporus .

Oxygen plant - Wikipedia

An unquestionable advantage of adsorption-based oxygen plants is the low cost of oxygen produced in the cases where there are no rigid requirements to the product oxygen purity. Structurally, the adsorption oxygen plant consists of several adsorbers, the compressor unit, pre-purifier unit, valve system and the plant control system.
