Evaluation of the pathogenicity of chrysanthemum stunt viroid variants against dahlia under different conditions

Abstract

Chrysanthemum stunt viroid (CSVd) is an important pathogen that decreases dahlia yields due to stunting symptoms. Here, we evaluated the effect of nucleotide sequence of CSVd, cultivation conditions, inoculum type and infection timing on CSVdinfected dahlia growth. Inoculation with CSVd after planting resulted in reduced plant height in the second cut flower, but not the first, indicating that the infection may How to cite this article:
