Effect Of Gibberellic Acid And Chilling On Nucleic Acids During Germination Of Dormant Peach Seed, Yuh-Nan Lin
Effect Of Gibberellic Acid And Chilling On Nucleic Acids During Germination Of Dormant Peach Seed, Yuh-Nan Lin
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
A study of nucleic acid changes influenced by gibberellic acid and chilling treatments in peach seed was performed in an attempt to reach a better understanding of the mechanism involved in breaking seed dormancy.
Gibberellic acid and the chilling treatment increased the RNA content. These two treatments which break dormancy also increased RNA, suggesting a similar mechanism involving RNA. Chilled seeds contained more RNA than did the gibberellic acid treated seeds.
DNA content remained unchanged regardless of treatment.
Dry seed had a greater ribonuclease activity than with soaked seeds. Enzyme changes did not correlate well with the RNA content in …
