In morphogenesis of plants cytokinin auxin ratio is important.

Question

Given reason :

In morphogenesis of plants cytokinin auxin ratio is important.

Answer 1

1. Auxins and cytokinins are growth promoting substances which stimulate cell division and cell enlargement. 

2. A high cytokinin promotes shooting in plants. 

3. A low ratio of cytokinin to auxin induces root development. 

4. A high ratio of cytokinin to auxin induces growth of buds and shoot development. 

5. Thus cytokinin and auxin ratio and their interactions control morphogenesis in plants.
