Effects of different aquasorb on germination and drought resistance of lavandula Angustifolia seeds
Abstract
Experiments were carried out to simulate the effects of three water-retaining agents on germination and drought resistance of Lavandula seeds. The germination rate, germination potential, germination index, and the changes of catalase and amylase activities during germination were observed after treatment with water-retaining agent. Our results show that (1) the use of a suitable water retention agent can promote the germination rate of Lavandula seeds, and the best germination result is obtained by using water retention agent B in 0.25%. (2) The peroxidase activity after using the water-retaining agent was lower than that of the control group; meanwhile, the amylase activity was higher than that of the control group. The best treatment results of water-retaining agent A, B and C are 0.5%, 0.25%, and 0.1%, respectively. We conclude that the water-retaining agent B in 0.25% is optimum concentration for Lavandula seeds.
