Effects of different concentrations of dissolved oxygen on
2021年2月28日 The effects of different concentrations of dissolved oxygen (DO; 4, 6, 7.5, and 9 mg L −1, control (CK), O1, O2, and O3, respectively) on the growth, photosynthesis, yield and quality of tomatoes and changes in soil microorganisms in a greenhouse were studied. These effects were evaluated for two years via a comparative design.
Effect of oxygen concentration on the growth of
2011年9月29日 In large-scale microalgal production in tubular photobioreactors, the build-up of O2 along the tubes is one of the major bottlenecks to obtain high productivities. Oxygen inhibits the growth,
The Effect of Oxygen Concentration on Photosynthesis in
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.

Oxygen levels in the air do not limit plant productivity
2011年2月17日 In the present study, the researchers employed a mass spectrometric technique together with isotopic water (H 2 18 O) to probe the effect of increased concentrations of oxygen on the mechanism of
How will future warming and CO2 emissions affect oxygen
2022年4月6日 As the planet gets hotter due to increased CO 2 concentrations, oceans are also warming up. As liquids warm, they can’t hold as much dissolved gas. This means a warmer ocean can’t hold as much carbon or dissolved oxygen, which marine life relies on for survival. While this effect has been most heavily studied in oceans, creatures living in
Effects of Plant Root Oxygen Deprivation in Relation to
2008年4月26日 solution. These concentrations varied between 2.5 and 8 mg/L. No one plant was held at extreme low or high oxygen concentrations for an extended period of time. Instead, the assignment of the oxygen concentration each plant received was changed three times each week on a rotating schedule; therefore each rose plant was given time to
Influence of Hydrogen Ion Concentration on the Growth
plant nutrients as phosphate, iron, and manganese. In addition to these indirect effects associated with pH which make it dif-ficult to interpret the responses of plants grown in a soil, there is a dearth of information about the effects of hydrogen ion concentration on plant growth, with other factors of the nutrient environment held constant.

2018年6月28日 The high concentration of the heavy metals such as lead can cause a number of toxic symptoms in plants that may be retardation in growth (Stunted growth), negative effects on photosynthesis (chlorosis), blackening of roots and different other symptoms. soil enzymes activities. In addition, heavy metals excesses may stimulate
Dissolved oxygen concentrations in pond aquaculture
2010年1月1日 At 26 degrees-C in freshwater, 36 and 60 percent saturation equate to dissolved oxygen concentrations of 2.91 and 4.85 mg/L, respectively.

Oxygen in Post Harvest: MonitoringControl Felix
Respiration, or breathing, is the process by which living things take in oxygen to breakdown carbohydrates. As shown in the equation below, carbon dioxide is one of the end products, along with water vapor and heat, as shown in the equation below: Carbohydrates + O2 CO2 + H2O + Energy. When respiration occurs in harvested produce, it uses

Much of the early work was concerned with animals but later necropsy studies showed that similar pulmonary lesions occurred in man (Pratt, 1958). It was evident that oxygen could exert a harmful effect either over a short period at high pressure or over a longer time at atmospheric pressure.
Do houseplants have any impact on oxygen levels?
2023年1月26日 You are correct that the effect on oxygen levels are not significant. There is a much greater impact is on CO2 levels. Still, with respect to the effect on indoor air quality, the most important influence of plants is the removal of a class of pollutants known as volatile organic compounds (a.k.a.
