DE ANGELIS, Verónica  e  CALVO, P.. Efecto de pies clonales sobre el crecimiento y productividad en manzano cv Cripps Pink en el Alto Valle de Río Negro y Neuquén. RIA. Rev. investig. agropecu. [online]. 2022, vol.48, n.2, pp.144-147. ISSN 1669-2314.

In order to evaluate the vegetative and productive development of different apple clonal rootstocks in the Alto Valle of Río Negro and Neuquén a trial with Cripps Pink cv. was planted with two rootstocks combinations: PI 80 and MM 111 with EM9 interstock. The vegetative and productive parameters evaluated were: trunk‐cross sectional area (ASTT, cm2); Cumulative yield per hectare (PA, tn/ha); Crop efficiency (EPA, kg/cm2) and in the last season the crop density (nº fruits/cm2 ASTT), the fruit size distribution (DC) and the coverage color (CF). The combination with PI80 was the least vigorous and had better productivity and fruit colour development. The EM9/MM111 combination has an acceptable productive level, so it could be an interesting alternative under poor soils conditions do not allow the use of dwarfing rootstocks.
