Abstract
Naphthaleneacetic acid ethyl ester (NAA-ethyl ester) sprays applied to the base of apple (Malus domestica Borkh.) nursery stock for sprout control suppressed sprout development. Rates of 0.25, 0.50, and 1% resulted in significantly less sprout development than the 0.125% rate. Sprout length was suppressed only by the second applications of the 0.25, 0.50, and 1% rates. A second application of the 0.50 and 1% rates killed the existing sprouts at time of application. Trees treated with 1% NAA-ethyl ester were shorter and smaller in diameter. The 0.25 and 0.50% rates were equally as effective in sprout control as the 1% rate, without adversely affecting tree height and diameter.
Abstract
Roots of sweet potato [Ipomoea batatas (L.) Lam.] and beet (Beta vulgaris L.) peeled with superheated steam, had higher peel and trim yields than did those peeled with saturated steam at the same pressure. Product recovery was greater with all steam-peeling methods than with caustic peeling. Direct injection of cold water into the partially pressurized steam atmosphere of the peeler also increased product recovery. Better color retention in processed beets was obtained from steam-peeled roots than from caustic-peeled roots.
