Claims Added

Angustifolia | entry_hardiness_observation | Angustifolia is named as one of several southern forms used in warmer districts but not reliable for northern rootstock needs.
European Sloe | taxon_context | European Sloe (Prunus spinosa) is grouped with imported European plum-type stock forms used in recommendations.
Japanese | entry_hardiness_observation | Japanese plum is explicitly judged unsuitable for northern plantings because the race lacks required hardiness.
Japanese | recommendation_context | Even where tested with some limited success in warmer regions, use is discouraged for northern use.
Miner | entry_hardiness_observation | Miner seedlings are discussed as a possible exception among southern forms, but the page states they still lack hardiness for this latitude.
Miner | entry_hardiness_observation | Southern forms including Miner are described as having sprouting objections and northern root-kill risk where non-sprouting hard roots are desired.
Myrobalan | entry_hardiness_observation | At the experiment station, Myrobalan stocks showed low winter persistence: only a very small percentage survived the first winter, and those that survived died the following summer.
Myrobalan | recommendation_context | If trees are suspected to be on Myrobalan, the bulletin recommends heavy fall mulching with well-rotted manure and removal during summer to reduce root-killing and avoid surface rooting.
Myrobalan | source_reference_abbreviation | These observations are credited as experiments conducted at this Station.
Native Plum (Native Plum Race) | selection_origin_reference | The text associates the native wild plum race as adapted across northern prairie states and provinces and notes its importance as a likely safer source for that race.
Russian | anecdote_snippet | The apricot root system was judged insufficient for plum tops, leading to second-year collapse (lopping to the ground) in nursery settings.
Russian | growth_habit | The failure mode described is structural failure under plum top load rather than normal long-term stock performance.
Russian | recommendation_context | Russian apricot was once promoted as a plum stock but this practice was later abandoned by nurserymen.
St Julien | anecdote_snippet | The text indicates St. Julien was being used as a practical imported stock option from Europe.
St Julien | rootstock_compatibility | St. Julien is used as a plum stock in the region and is described as having stock value comparable to Myrobalan.
Wayl | entry_hardiness_observation | OCR reads this as a named southern plum-like form; its use is associated with limited northern suitability due sprouting and hardiness concerns in nearby context.
Western Sand | fruit_size | Fruit from this stock was stated to be fully up to standard size and quality.
Western Sand | growth_habit | Some trees became too rampant, with tall stems that sagged or lopped under heavy crops.
Western Sand | productivity | Trees on this stock behaved as dwarfing and early bearers and were described as yielding abundantly.
Western Sand | rootstock_compatibility | The entry links western sand cherry to both stock utility and direct fruiting observations, indicating strong practical use value at this Station.

Miner | entry_hardiness_observation | For this latitude, the Miner is said to lack hardiness.
Miner | recommendation_context | Miner seedlings are noted as a possible exception among southern plum stocks because their hardiness would be about that of the Miner.
Miner | rootstock_compatibility | Miner is listed among southern plums that have been used as stocks in the South.
Wayland | recommendation_context | Southern plum stocks such as Wayland are criticized because their tendency to sprout is objectionable where non-sprouting roots are hardy, and at the North they root-kill.
Wayland | rootstock_compatibility | Wayland is listed among southern plums that have been used as stocks in the South.
Wildgoose | recommendation_context | Southern plum stocks such as Wildgoose are described as objectionable where non-sprouting roots are hardy, and as root-killing in northern conditions.
Wildgoose | rootstock_compatibility | Wildgoose is listed among southern plums that have been used as stocks in the South.
