Other claims from this paper (9)
- Observation Fine root length density increased in six of ten rootstocks over time.
- Observation AM colonization generally exceeded 60% of fine root length for all rootstocks.
- Association AM colonization differed significantly by rootstock and sampling time.
- Association Ruggeri 140, Kober 5BB and SO-4 rootstocks had consistently higher AM root colonization.
- Association The proportion of roots with arbuscules declined from 1999 to 2000 in rootstocks with the highest crop loads.
- Association AM colonization of different rootstocks was positively correlated with yield.
- Association The proportion of roots with arbuscules was negatively correlated with yield in 2000.
- Observation Rootstocks differed slightly in their ability to form mycorrhizas.
- Association Crop load and soil moisture had a large influence on AM root colonization.
