Some experiments revealed that the Ca2+ has a relationship with drought resistance. In this paper, some physiological and biochemical indices were studied in order to analyze the effect of Ca2+ treatment on the drought resistance of Brassica napus. The physiological and biochemical experiments revealed that the proline content and the soluble sugar contents in the Ca2+-treated B. napus were much higher than those of water-treated B. napus. However, the content of malonaldehyde in the Ca2+ treated B. napus was lower than that of control. The transpiration and stomatal conductance analysis show that the transpiration and stomatal conductance in the Ca2+-treated materials were lower than those of water-treated materials. Further research revealed that the stomata hatch of Ca2+-treated materials was markedly less than that of water-treated materials, which indicated that the closure of the stomata was the main reason for the decrease of transpiration and stomatal conductance.
