| 总结: | The application of antigibberellins to potato plant cultures results in an accelerated tuber appearance, caused by stimulation of pith-,and cortex-cell growth, particularly in the radial direction. Their growth considerably precedes the initiation of parenchymatous cell divisions, which are the first steps of naturally occurrring tuberisation, regulated by a different mechanism than the quantitative proportion of endogenous gibberellins and cytokinins. Part of the cortex cells change the orientation of their divisions to a periclinal one. The xylem parenchyma cells also undergo hypertrophy. |
