How a corn plant develops?
Once planted, corn seeds absorb water from the soil and begin to grow. VE (emergence) comes when the coleoptile (spike) pushes through the soil surface. Corn plants can emerge within five days in ideal heat and moisture conditions. … All leaves and ear shoots the plant will ever produce form from V3 to about V5.
What is the first stage of corn production process?
The first stage observed in the vegetative period is known as VE, which is emergence. At this period, the coleoptile is fully visible, yet no leaves are fully developed. Full development of the first leaf is known as V1. The number of leaves that are completely developed determine the vegetative stage the plant is at.
What happens to the primary root of corn as it develops?
The nodal roots begin to develop above the coleoptile node at about VE. Within 2 or 3 weeks after plant emergence. the nodal roots become the main root system of the plant. This nodal root system becomes well distributed in the soil, so precise fertilizer placement is less critical after these roots have developed.
