In the years 2007-2008 a special experiment was carried out. Its aim was the evaluation of growth of three generative rootstocks: ‘Antonówka’ seedling, Pyrus communis var. caucasica seedling and ‘Wangenheim Prune’ seedling in a nursery in “replant disease soil” enriched with organic matter coming from the leaves of Beta vulgaris var. saccharifera, leaves of Ginkgo biloba and straw of Sinapis alba. One of the combinations were the seedlings, which were growing on the place where there had not been a nursery before. The rootstocks of ‘Antonówka’ seedling grew the best on the stand where the leaves of G. biloba were the organic matter. The best growth of ‘Wangenheim Prune’ and P. communis var. caucasica rootstocks was observed in the combination with no “replant disease soil” stand, and in next turn after the use of B. vulgaris var. saccharifera leaves and G. biloba. The smallest percentage of rootstocks of P. communis var. caucasica with traces of Agrobacterium tumefaciens was noted for the combination with no “replant disease soil” stand and after the use of straw of S. alba.
