Table 2 The effect of two brassinosteroids – castasterone (CS) and homocastasterone (HCS) that were present separately and in mixtures (x_CS – molar fraction of castasterone in the mixed solution) – on the limiting area per molecule (A_lim [Å₂]), collapse pressure (π_coll [mN/m]) and maximal compression module (C_s⁻¹_max [mN/m]) of the monolayers that had been prepared from phosphocholine (PC 18:3) at 20 °C, 10 °C and 30 °C. Mean values (± SE) marked with the same letters for a measurement were not different according to Duncan’s test (P ≤ .05)
