‘Carina’ rose was grown on seven different rootstock clones. These, combinations were tested for effect on flower production and mineral content of the leaves when grown in fumigated ground beds in an evaporatively cooled plastic greenhouse. Plants growing onR.odorataISU 5710–2 produced the highest flower yields followed byR.fortunianaand R.manettiwhileR.multifloraISU 62–5 produced the lowest number of blooms. Rootstocks caused large differences in the levels of some minerals in the leaves.R.fortunianacaused a Mn accumulation that was five times the quantity developed byR.odoratabut this did not seem to be related to flower production. However,R. odoratawas a superior accumulator of K and under conditions of relatively low supplyR.fortunianaand R.odoratawere good accumulators of N and K. These factors were related to flower yield.
