| Abstract: |
| From 1999 to 2002，Tianda-2116，a plant cytolemma regulator，was applied to plot experiments and production demonstrations in order to examine its practical efficacy and method for dryland maize in East Gansu piovinces．The results were shown as follows： “Tianda-2116” could accelerate its jointing and heading，raise its drought resistance in the flowering stage，increase plant height，ear-position height，number of kernels per ear and thousand kernel weight，and reduce the bald rate．Moreover，the increment of soaked seeds reached10．27％～18．91％，and the optimal concentration was0．50％；the increment of the spraying came to7．32％～11．7％．The reasons for yield increase varied from year to year. |
