Borkh.) is functionally extinct i n its native range. Short term conservation methods for C. dentata in tiss ue culture were developed and improved upon in this work. Methods to impro ve multiplication rate (physiological stage of source material and incubat ion temperature) and microshoot quality (effect of exogenous medium modifi cations in 6-benzylaminopurine\, calcium\, magnesium\, boron\, and gelling agent type and concentration on the incidence of shoot top necrosis (STN) ) were investigated in the axillary shoot culture of genotypes from geneti cally diverse sub-populations of C. dentata. Physiological stage of source material effected multiplication rate\, with seedling-stage source materi al producing the most vigorous cultures. Incubation temperature effected m ultiplication rate in three out of eight genotypes tested.\n\nEveryone in the 91ºÚÁÏÍø community is welcome to attend a PhD oral defence. Please join us in celebrating the accomplishments of our PhD candidates.\n DTSTART:20190322T171500Z DTEND:20190322T171500Z LOCATION:P-117\, Parasitology Building\, CA\, QC\, St Anne de Bellevue\, H9 X 3V9\, 21111 Lakeshore Road SUMMARY:PhD Oral Defence: Optimizing short term conservation methods for a functionally extinct tree species\, American chestnut (Castanea dentata (M arsh.)
