Effects of Tetcyclacis on Plant Growth and Development in Triticale cv.Lasko

Experiments with tecyclacis applied as a seed-dressing carried out with triticale cv.Lasko in pots in the glasshouse and in hand-sown plots in the field.The sesults showed that tetcyclacis significantly delayed seedling emergence and inhibited the elongating growth in plant seedling stage,but not affected the growth and development of the adult plant during the late stage of stem extension and the stage of grain expansionl.No significant difference was found in fertile stem number,grain quality and yield between the treated plants with tetcyclacis and control.
