Interrelationship of Aphelenchoides fragariae and Xanthomonas begoniae on Rieger begonia.
Disease complexes initiated by plantparasitic nematodes and bacteria on aerial plant parts are relatively uncommon. Interactions involving Aphelenchoides ritzemabosi (Schwartz) Steiner & Buhrer, Anguina tritici (Steinbuch) Chitwood, and Ditylenchus dipsaci (Kiihn) Filipjev with species of Corynebacterium are known (1, 3, 8). Ditylenchus dipsaci also is reported to interact with Erwinia rhaponti...
متن کاملPhotoreception in sparrows: response to photoperiodic stimuli.
a typically normal learning curve, represents the function of both cerebral hemispheres during learning. The learning curve in Fig. 3 must then represent the function of only one hemisphere during learning. They are respective "bilateral hemispheric" and "unilateral hemispheric" products. Participation of only one hemisphere during learning would necessarily limit by one-half the available amou...
متن کاملPhotoperiodic Flowering Response of Biloxi Soybean in 72-Hour Cycles.
Recently, evidence has accunmulated to indicate that the photoperiodic control -of floral induction is mediated by an endogenous rhythm with periods of approximately 24 hours (9, 10, 11, 12, 13, 18, 19, 20, 21, 22). It has long been known that the floral response of Biloxi soybean varies with the length of the photoperiod (4, 5, 6, 7, 18). The optimum response with 24-hour treatment cycles is o...
متن کاملEfficient shoot organogenesis of begonia (Begonia rex Putz.) induced by thidiazuron
The effects o f thidiazuron (TDZ) on adventitious shoot bud formation from leaf and peti ole explants excised from in-vitro-grown plantlets o f a begonia were tested by a two-step procedure: a short exposure (5 to 120 min) to 40 pM TDZ in liquid MS medium followed by culture on agar-solidified MS medium without growth regulators. Exposure of explains for five min to TDZ induced bud formation, ...
متن کاملInheritance of Photoperiodic Response and Tillering I N Maize - Teosinte
HE importance of day length as a determining factor in the time of T floral initiation in plants was first reported by GARNER and ALLARD (1920). Since then numerous investigations have been conducted on this phenomenon, and many plants have been classified into short-day, long-day and day-neutral types on the basis of their response to photoperiod. All known varieties of teosinte belong to the ...
