| Abstract: | The article studies the physiological effect, caused by mannitol, sorbitol, melibiose and PEG disposal, on the mesophyll organism of the barley. It is known that 30 percent PEG is helpful to growth of the budding and that PEG of different density can influence the physiollogical action of osmotic pressure medicine, and that mannitol disposal is helpful to cutting the seepage of the mineralion and the biological molecule. It can also improve the content of the element. Sorbitol and melibiose have different physiological effect on mannitol, the article also discusses the mechanism about PEG and the differences among the physiological action of different osmotic pressure medicines. |
