Figure 1. Ethylene biosynthesis and its influences on various physiological processes. Ethylene is involved in many aspects of the plant life cycle, including plant morphogenesis, defense, flowering, sex expression, embryogenesis, seed germination, root hair development, root nodulation, flower senescence, abscission, fruit ripening etc. and a number of evidences proved the usefulness of silver nitrate in the inhibition of ethylene-induced adverse effects.
