ABSTRACT
Adaptabil rootstock was named in Romania, in the year 2 000, by Research Institute for Fruit Growing (RIFG) Pitesti (the owner), together with another rootstock, Miroper, both of them being the first Romania’s for peach clonally rootstocks. Adaptabil rootstock is resistant to diseases, drought and waterlogging, has a medium to low vigor, and may be used on a large range of soils. It was named like a clonally rootstock for peach varieties (nectarine included) but, it is a polyvalent rootstock, proper to be used for European plum (Romanian Tuleu group and Reine Claude excluded) and for apricots (only non congenial varieties). The studies were carried out at RIFG in respect with propagation abilities during the end of July and mid of August period of time, involving two kind of cuttings, treated with two rooting promoters and planted on three rooting media. The best rooting media was sand (ready to find in Romania), followed by a mixture 1:1sand and turf. The best kind of cuttings proved to be those made from the next segment after the top of the shoots (we call them base cuttings). Rooting percentage of the base cuttings was between 97.5 (test, untreated), up to 100 (RV1 stimulus). The base rooted cuttings are fit to be planted in nursery for summer budding, but are not the same situation with the cuttings made from the top of the shoots where 50% out of them need to be stacked in nursery at small distances for another year. That is the reason for which we are thinking for another propagation technology intended to use only 10-15 cm length top cuttings, instead of 30 cm, and much longer base cuttings (40-45 cm).
