Outline of Final Research Achievements

Responses of growth and grain yield of millets to combined stress (drought and salinity or hypoxic and salinity) were investigated. The plant growth rate of Echinochloa utilis Ohwi et Yabuno and Panicum miliaceum L. were higher than that of Setaria italica (L.) P.Beauv. and Brachiaria ramosa L. and this showed E. utilis and P. miliaceum had more tolerance to combined stress (120mM NaCl and 20% oxygen compared to control). The decline of growth by combined stress was mitigated by application of calcium. The decrease of grain yield of E. utilis and P. miliaceum were higher than those of S. italica and B. ramosa and this showed E. utilis and P. miliaceum had more tolerance to combined stress (drought and 120 mM of NaCl).
