BORDIN, Ivan et al. Architecture and extension of roots of seven grapevine rootstocks in North of Paraná State. Rev. Bras. Frutic. [online]. 2003, vol.25, n.3, pp.526-527. ISSN 0100-2945.

It was studied the structure of the root system of 5 year old IAC572, Kobber 5BB, Rupestris du Lot, IAC 313, IAC 766, 'Ripária do Traviú' and 420 A grapevine rootstocks. The roots were exposed using the excavation method and evaluated by the SIARCS 3.0 software. To evaluate the conformation of the rootskocks root system it was used an architecture diagram attributing scores. 'IAC 572' had the largest root system and '420 A' had the smallest. There were no statistical differences in scores atributed to the architeture of the root systems. The most vigorous had the highest distortion frequency.

Keywords : Vitis sp.; excavation method; root lenght.
