Which is the plant stress hormone?

Two rods of different materials having coefficients of thermal expansion alpha_1 , alpha_2 and Young's modulii Y_1 , Y_2 respectively are fixed between two rigid massive walls. The rods are heated such that they undergo the same increase in temperature. There is no bending of the rods. If alpha_1:alpha_2=2:3 , the thermal stresses developed in the two rods are equal provided Y_1:Y_2 is equal to
