Apple proliferation

, : Apple proliferation. Acta Horticulturae (44): 175-199

a. Morvan, G.; Castelain, C. (Sta. Path. Veg., INRA, Montfavet, France). (New evidence of the high sensitivity of Malus dawsoniana to apple proliferation disease and of its value for testing apple trees) (175-182). When inoculated directly in June M. dawsoniana develops leaf reddening during the following autumn, and bark splitting and scaling in the next spring. Later the scion dies and the rootstock gives suckers ending in witches' brooms.

Fruit of the infected summer vars. matured earlier and often dropped. Seeds were fewer and underdevelo...
