Abstract:

Effect of oligochitosan on enzyme activities associated with the resistance to epiphyte and bacteria diseases of plants has been reported. Oligochitosan was prepared in our labarotory. Brassica napus L. seedlings without or with oligochitosan treatment under drought stress were determined with PP-Systems company CIRAS-2 portable Photosynthetic apparatus in the trial. The result indicated that the net photosynthetic rate (Pn), stomatal conductance (Gs), intercellular CO2 concentration (Ci) decreased significantly (P < 0.05), while stomatal limitation (Ls) increased significantly (P<0.05) in Brassica napus L. seedlings under drought stress. The Pn, Gs, and Ci increased, while Ls decreased when Brassica napus seedlings treated with 50 mg L-1 oligochitosan under drought stress. It indicated oligochitosan treatments are beneficial to reduce the drop of Pn caused by stomatal limitation in Brassica napus L. seedlings under drought stress. The dry weight of roots of rapes also increased by spraying oligochitosan under drought stress.

Key words: Brassica napus, Oligochitosan, Net photosynthetic rate (Pn), Stomatal conductance (Gs), Intercellular CO2 concentration (Ci), Stomatal limitation (Ls), Dry weight (DW)
