PGRs can be broadly divided into two groups – plant growth promoters and plant growth inhibitors. Ethylene:
| 1. | belongs to the group of plant growth promoters |
| 2. | belongs to the group of plant growth inhibitors |
| 3. | could fit either of the groups, but is largely an inhibitor of growth activities |
| 4. | could fit either of the groups, but is largely a promoter of growth activities |

The increased growth per unit time is termed as growth rate. The exponential growth can be mathematically expressed as:
1. Lt = L0 +rt
2. Lt = L0 rt
3. W1 = W0ert
4. W1 = W0 + ert
1. Lt = L0 +rt
2. Lt = L0 rt
3. W1 = W0ert
4. W1 = W0 + ert
