Abstract

Experiments on root restriction effect were carried out on micropropagated peach rootstock (GF677) plants grown in pots with different volume (1350 and 270 ml). Root restriction reduced plant growth expressed as shoot length, FW and DW accumulation and leaf area. Application of a triazole (BAS 111, GA biosynthesis inhibitor) or TIBA (inhibitor of auxin polar transport) also reduced plant growth as compared to root restriction. Pn measured on expanded leaves developed during the time-course experiment showed to be affected by root restriction. In fact the assimilation rate exhibited by plants grown in 270 ml volume pots remained at lower level at least at the lower light intensities. TIBA treatment dramatically reduced the assimilation rate at all the light intensities tested, while BAS111 did not induced evident differences as compared to the control plants. The stomata density per leaf doubled in the plants grown in 1350 ml pots as compared to that of plants in the 270 ml pots.
