Temperature Effects on Reproductive Processes of Russian Wildrye1

  1. Warren P. Clary2

Synopsis

Synopsis

Temperature treatments ranging from −1 to 21° C. were imposed for 24 hours on Russian wild-rye plants during anther emergence. An inverse relationship resulted between treatment temperature and the time required for embryo initiation. Various temperature-related floral injuries were observed. Most of the freezing injury occurred in the anthers, while the principal warm temperature injury was to the pistillar tissue. The warm temperature effects were exaggerated when followed by a warm greenhouse environment.
