Phyllochron

The phyllochron is the intervening period between the sequential emergence of leaves on the main stem of a plant, also rendered as leaf appearance−1. This measurement is used by botanists and agronomists to describe the growth and development of plants, especially cereals. The term phyllochron was first described in 1966.[1] The interval between leaf appearances can be recorded in both standard measurements of time as well as thermal time (e.g. growing degree units).[2] One phytomer unit is added over the course of one phyllochron. No significantly robust equation to predict phyllochrons has been developed.[3]
