how does auxin and cytokinins promote growth in plants
Answers
Answer:
When cytokinin and auxin are present in equal levels, the parenchyma cells form an undifferentiated callus. More cytokinin induces growth of shoot buds, while more auxin induces root formation. Cytokinins are involved in many plant processes, including cell division and shoot and root morphogenesis.
Auxin and Cytokinins are the growth promoters in plants.
Agricultural Role of Auxin:
1) Auxins promote elongation of stem
2) It promotes the growth by the elongation of cells in the apical meristem.
3) Growth in the lateral bud is inhibited when the apical bud of a tall plant remains intact.
Agricultural Role of Cytokinins:
1)Cytokinins are plant hormones that cause increased cell division by stimulating the process of mitosis.
2)They are made naturally by plants but have been synthesized by humans.
3) Increased mitosis results in plant growth and the formation of shoots and buds, as well as the development of fruits and seeds.
