We studied relationships between diurnal patterns of stem water potential (Ψ STEM ) and stem extension growth of the same scion cultivar growing on three rootstocks with differing size-controlling potentials. The peach trees ( Prunus persica  (L.) Batsch) used in this field experiment consisted of an early-maturing freestone cultivar, ‘Flavorcrest,’ grafted onto three different rootstocks: Nemaguard (a vigorous seed-propagated control,  P. persica  ×  P. davidiana  hybrid), Hiawatha (an intermediate vigor rootstock, derived from an open pollinated seedling of a  P. besseyi  ×  P. salicina  hybrid) and K-146-43 (a semi-dwarfing rootstock,  P. salicina  ×  P. persica  hybrid). Diurnal patterns of Ψ STEM  and stem extension growth were measured on six dates (March 29, April 12, April 26, May 10, May 24 and June 18) during the primary period of peach shoot extension growth. Rootstocks clearly affected diurnal patterns of Ψ STEM  and stem extension growth. Trees on K-146-43 had the lowest midday Ψ STEM  and stem extension growth. Differences among rootstocks in the amount of diurnal oscillation in Ψ STEM  explained stem extension rate differences induced by the three rootstocks. The sensitivity of shoot extension growth to tree water relations tended to decrease as the season progressed and was not apparent by mid-June. The results of the study indicate that water relations may play an important role in the dwarfing mechanism induced by size-controlling peach rootstocks.

Daily shoot extension growth of peach trees growing on rootstocks that reduce scion growth is related to daily dynamics of stem water potential
