Anthesis Growth Stage

Notice that the drawing on the right of the illustration has two Z codes describing its four main stem leaves (Z1.4) and two tillers (Z2.2).Booting, heading and anthesis These stages are easily identified (see photos).For ex-ample, stages Z1.1 to Z1.9 are when main stem (MS) leaves 1 to 9 become visible.

At that time, the enclosed growing point is still at the crown of the plant below the soil surface.

Terminal spikelet (p 90) is when the tiny spike has produced all its spikelets.

This overlap means that your crop can have two or even three Zadoks stages at the one time.

The drawings illustrate germination and 3 stages during vegetative growth with their Zadoks decimal codes (identified as Z in this booklet but elsewhere often abbreviated to DC for Decimal Code).

Double ridge stage The following figure relates the external Zadoks stages of the plant (red) and the two internal stages, double ridges and terminal spikelet (check the vertical text).

Wheat continues to go through the heading and flowering growth stages across central and northern Ohio.

The maximum potential number of florets (and therefore maximum yield potential) is now set.

The tillers produced last during stem elongation will often die. Radiation from now till anthesis will greatly affect grain number per unit area particularly in hot climates.

They bleach white within 3 or 4 days (mid anthesis or Z6.5).

Most of the main stages are shown on the diagram on page 8 where they are associated with other developmental processes (shaded green) and with the components of yield.

    The hardening treatment improved DW accumulation after anthesis and its contribution to grain mass which ultimately resulted in increases in grain yield. Thus, hardening by multiple waterlogging events during the vegetative growth stage could effectively enhance tolerance to a waterlogging event during the sensitive generative growth stage of.…
