CO2 and water vapor fluxes of hydroponically grown wheat and soybean canopies were measured continuously in several environments with an open gas exchange system. Canopy CO2 fluxes reflect the photosynthetic efficiency of a plant community, and provide a record of plant growth and health. There were...
To understand the new breakthrough, it is important to know how photosynthesis works. Plants take in carbon dioxide and water from the air and soil. Within the plant cell, the water is oxidized. This transforms the water into oxygen and the carbon dioxide into glucose (葡萄糖). The plant ...
There also appears to be no adaptive response once the sucrose is removed to sustain the plant following transfer to soil. There is evidence elsewhere that exogenous sucrose also affects RubPcase activity in photoautrophic suspension cell culture, and that the role of PEPcase as a carbon-fixing ...
