|January 1, 1978
Summary
Radioactive ethephon uptake and distribution in rye plants were studied. Ethephon applied to roots showed better uptake, while foliar application led to higher translocation in phloem, impacting plant growth.
Area of Science:
- Agricultural Science
- Plant Physiology
- Biochemistry
Context:
- Investigating plant growth regulators is crucial for crop management.
- Understanding ethephon's (a culm stabilizer) uptake and distribution is key to its application in rye cultivation.
Purpose:
- To investigate the uptake and distribution of radioactive ethephon in rye plants.
- To determine the transport pathways and metabolic fate of ethephon following different application methods.
Summary:
- Radioactive ethephon was infiltrated into rye plants via roots, leaves, and stem cuttings.
- Root uptake was more complete than foliar uptake, but foliar application resulted in higher phloem translocation.
- Ethephon concentrations decreased significantly within five days, degrading into ethylene and carbon dioxide.
Impact:
- Provides insights into the physiological behavior of ethephon in plants.
- Informs optimal application strategies for ethephon as a plant growth regulator.
- Contributes to understanding the metabolic pathways and degradation of ethephon in agricultural settings.
