Phylogenetic analysis shows that New Zealand isolates of Neonectria ditissima are similar to European isolates

New Zealand Plant Protection, 2021
Neonectria ditissima causes a debilitating apple tree canker disease. We determined the efficacy of polymerase chain reaction primers, originally designed for European strains, by sequencing New Zealand strains. The concatenated ribosomal inter-transcribed spacer and β-tubulin gene regions of 17 New Zealand isolates were compared with those of two ...

Short‐term effects of moderate severity disturbances on forest canopy structure

Journal of Ecology, Volume 111, Issue 9, Page 1866-1881, September 2023., 2023
Study indicates that both press and pulse disturbances can inhibit canopy height growth over time. However, while the impact of press disturbances on other dimensions of canopy structure could not be clearly detected, likely because of compensatory growth, the impact of pulse disturbances over time was more readily apparent using multi‐temporal light ...

Effect of freezing of <i>Neonectria ditissima</i> inoculum on its pathogenicity

New Zealand Plant Protection, 2015
The fungus Neonectria ditissima causes European canker of apple To determine the pathogenicity of different isolates conidial inoculum of each isolate needs to be prepared Freezing inoculum ensures that conidia do not germinate before inoculation and facilitates screening of large numbers of isolates In this study conidial suspensions of three ...
