Factors affecting survival and vigor of cold-stored strawberry nursery stock

Creator:: Decker, Bruce Richard
Abstract:: Field survivals of strawberry (Fragaria x ananassa) runner plants dug from December to April in both 1979 and 1980 were above 9C% when planted about May 1.

Banana quality : flavor volatiles under anaerobic and aerobic conditions

Creator:: Chantrachit, Theeranuch
Abstract:: Alcoholic off-flavor and accompanying volatile compounds produced by bananas (Cavendishii spp) held at 20°C and subjected to aerobic (air control treatment) or anaerobic conditions (nitrogen treatment) were compared by solid phase micro extraction (SPME), a newly developed method for volatile separation. In general, volatile production was suppressed under anaerobic conditions...
