The maximum fresh mass of shoot and root in B.juncea was recorded at 10 mM Ca2＋ concentration. The relative growth rate of shoot of both species reached its maximum at 8 mM of Ca2＋ concentration. Average rate of Ca2＋ intake （lCa） was higher in B. juncea than 6. campestris. In B. juncea, the average transport of Ca2＋ to shoot increased by 19%, 38%, 119%, 125% and 169% compared with the control. Furthermore specific utilization rate of Ca2＋ was higher in B. juncea than B. campestris. In B. campestris it increased by 9%, 32%, 41% and 59% at 4, 6, 8, and 10 mM of calcium in comparison to 2 mM Ca2＋ treatment. At 4, 6, 8 and 10 mM of Ca2＋ application, the increase in the leaf area ratio was 10,17, 23 and 30%, respectively. In the shoot and root portions of B. campestris and B.juncea, Ca2＋ had a linear relationship with potassium and sulfur, whereas it was in antagonism with sodium ion.展开更多
