Free abscisic acid (ABA) in Yellow Globe Danvers onion tissues was
determined during maturation and storage. The amount of ABA in leaf
tissue reached a maximum (1.81 ng/gm dry weight) at 40% top fall. Neck
tissue ABA reached a maximum (0.33 ng/gm dry weight) at 60-70% top fall.

Pre-harvest foliar desiccation of Yellow Globe Danvers onions was
investigated as a means to improve harvest procedure and to reduce
storage losses. Foliar desiccation tended to increase storage disease
and sprouting incidence versus the untreated controls. Paraquat
approximately doubled storage disease in both years. Stoddard solvent
and ethephon increased disease...
