Kinetic Analysis of Plant Ethylene Production Using ...

Non Technical Summary A primary plant stem maintains an upright position and can reorient to the vertical after being displaced. A change in stem orientation causes an increase in the production of the gaseous plant hormone ethylene. Increased ethylene acts to regulate the plant's response to gravity and is also known to control many growth and developmental processes important for maximum ...
