Aluminum effect on nutrition and development of grapevine rootstocks (Vitis spp.)

Abstract

The proposal work was to detect the growth capacity and absorption of minerals on grape rootstocks in acid soils with high contents of Al. The rootstocks tested were: ‘IAC 572’, ‘1045 P’, ‘RR 101-14’, ‘Kober 5BB’ and ‘Gravesac’, at 0 %, 13,5 %, 27 %, 40,5 % and 54 % aluminum (Al) saturation levels. Plants height, roots length, leaves, stems and total dry weight; roots, stems and leaves nutrients content (N, P, K, Ca, Mg, S, B, Cu, Fe, Zn and Mn) and Al were evaluated.

Development characteristic differences were observed only in rootstocks. ‘IAC 572’ showed the highest roots, stems and leaves development, followed by ‘Gravesac’ and ‘RR 101-14’. Rootstocks were different in soil Al and nutrient content, and some interactions occurred between both factors. ‘IAC 572’ had the highest: growth, Ca, Mg and Zn roots concentration and N, K in aerial part. ‘Kober 5BB’ had the smallest growth but accumulated more: N, Fe and S in roots, and Al, Cu and Fe in aerial part. ‘Gravesac’ had the highest concentration of N, P, K, S and B in aerial part.

Increasing Al soil contents reduced: Ca and S in roots, Ca in the stems and leaves; but increased: Cu and Zn contents in roots and Zn and Mn contents in the stems and leaves. ‘IAC 572’ and ‘Gravesac’, retained more Al in roots when Al contents increased in the soil.
