Research Abstract

Basic research and field test for the development of greening technology were conducted by utilization of salt-tolerant weeds to the salt-affected soil spreded in the world.
For the field test, several weeds species were transplanted on the saline soil in Phimai of Northeastern Thailand to make clear the effects of weed planting on the changes of micro-environments and the possibility in greening of saline soil. Salt content was decreased in all the plots of the weed planting compared with that of no weed control plot, suggesting that weeds may be used to improve the saline soil as the pioneer plants. However, it is unclear that the effects on decreasing saltcontent in soil are due to the evaporation of soil moisture from the soil surface or the absorption of salts into the plants. Furthermore, it is necessary to conform the effects for a longer time and the magnitude of the effects to establish the greening technology by utilization of weeds.
During the research period, the mechanisms of salt damage and salt tolerance in weed species in the viewpoint of the occuring and sacvenging of activated oxygens under the salt stress and the development of propagation of the usuful weeds for the greening of saline soil by tissue culture technology were also investigated.
