| Abstract: | Chill-stressed or aged bean (Phaseolus vulgaris cv. 194) plants showed relative increase in the campesterol content of the primary leaves. Sitosterol/stigmasterol ratio declined significantly 24 h following transfer of chilled plants to warmer conditions. Sitosterol/stigmasterol varied markedly according to plant age, showing a decline during the leaf greening phase but an increase by the senescent (leaf-yellowing) phase. |
