Other claims from this paper (11)
- Observation Grafted Malus trees differed in response to apple proliferation infection.
- Observation The tested material was divided into five groups by recovery, witches broom, mortality and MLO population.
- Observation Group I domestic apple had low recovery and mortality, frequent witches broom, and high MLO titer.
- Observation Group II had higher mortality than group I.
- Observation Group IV mortality exceeded 50%.
- Observation Group IV usually had low witches broom formation and MLO numbers in phloem.
- Observation Most group V trees recovered or never showed symptoms and had low mortality.
- Observation After inoculation, group V MLO populations were low or degenerate.
- Observation MLO-positive samples decreased during recovery until the organism was undetectable in most cases.
- Observation Group V came from apomictic rootstock selections crossing M. sieboldii and M. sargentii with M. pumila.
- Recommendation The authors judged group V suitable as resistant rootstocks for controlling apple proliferation.
