USE OF MICROPROPAGATION AND TISSUE CULTURE TO INVESTIGATE GENETIC DISORDERS IN ALMOND CULTIVARS |

| Abstract:
Noninfectious bud-failure (BF) in almond is a "genetic disorder" characterized by heat sensitivity of separate propagation-clones within certain cultivars. A correlation between the in vivo characteristics of separate propagation-clones and their in vitro behavior in tissue culture is shown. BF callus-clones show enhanced proliferation in high nitrogen media at 25°C and depression at 35°C. Differential response between BF and "normal" callus-clones may require growing in low nitrogen medium. Relationship to clonal nomenclature is discussed. | |
