Abstract
In this thesis, two pea varieties, Longwan 1 and S4008 have been used as the experiment materials, and under different concentrations of NaCl stress, response of germination and seedling growth of pea seeds were investigated. The results show that 10 mmol·L–1 NaCl could promote seed germination, and 2 varieties of pea germination rate, germination, plumule and radicle length, seedling fresh weight and dry weight, relative water content, chlorophyll content were significantly higher than controls(P0.05). 25 mmol·L–1 NaCl treatment was slightly higher than the control, but the difference was not significant; germination index decreased with increasing salt concentration, 10, 25 mmol·L–1 treatment and the control were not significant. High concentration of NaCl(50, 100, 200 mmol·L–1) significantly inhibited the germination rate, germination, plumule and radicle length, seedling fresh weight and dry weight, relative water content and chlorophyll content(P0.05), and the radicle showed greater decreasing trend than germ. Extremely high concentration NaCl(300 mmol·L–1) stress could not germinate practically. The cell membrane permeability increased with the salt concentration increased significantly(P0.05); malondialdehyde increased with the concentration of NaCl first and then decreased. The treatment of 100 mmol·L–1 reached a maximum value; and the proline content was increased firstly and then decreased(P0.05). 25 mmol·L–1 reached the minimum value. The radicle is a more sensitive part under salt stress. Two pea varieties show salt resistant ability in the order of: S4008Longwan 1.
