Both ethylene biosynthesis and membrane breakdown, which appear to be closely linked, seem to involve free radicals, although the sequence of events generating these free radicals is still poorly understood.

The results of this study suggest that foliar application of SA and HA + SWE may alleviate decline of photochemical efficiency and turf quality associated with increased UV-B light levels during summer. The total nitrogen content of the seed produced by seaweed-treated plants remained within the parameters laid down by the malting industry. This has been supported J Plant Growth Regul 1:161–171. Se encontraron diferencias significativas al distribuir la producción según distintas categorías de peso; el rendimiento de frutos de melón con un peso entre 601-800 gramos fue superior en plantas tratadas con solo Algamix respecto a los demás tratamientos; el rendimiento de frutos de melón con un peso entre 801-1000 gramos fue superior en plantas tratadas con solo Engordone respecto a los demás tratamientos. Several authors associated positive effects of ANE to higher chlorophyll concentration, nutrient uptake and nutrient use efficiency. mycorrhizal development more than the control treatment.
