How long does it take for wheat to tiller after sowing (how many days does it take for wheat seedlings to tiller)

How long does it take for wheat to tiller after sowing?

There is a regular pattern in the tillering of wheat. Generally, seedlings will emerge 6 days after sowing , and tillering will begin 15 days after emergence . It takes about 20-25 days from sowing to tillering .

Normally, wheat has two vigorous stages of tillering growth in its lifetime: winter wheat sown at the right time starts tillering about half a month after germination, and stops tillering when the average temperature drops to 3°C and enters the wintering period, which is the first vigorous stage of wheat.

After wintering, when the temperature rises above 3℃, wheat begins to turn green, tillering continues, and the second vigorous stage appears during the rising period. Under normal circumstances, the main stem and most of the tillers before the New Year have a high ear formation rate. However, the tillers that appear late before winter and late spring have a low ear formation rate and generally cannot form ears.

The standard for strong wheat seedlings before winter is: before winter, each plant has an average of 2 to 3 tillers, 4 to 5 secondary roots, and the main stem can grow 6 to 7 leaves (including heart leaves), achieving synchronous growth of leaves, roots and tillers.

What is tillering

Tillering is a very random situation, ranging from a few to dozens. At present, the determination requires field investigation and careful observation of the soil. Take a certain number of samples and calculate the average.

The tillering of wheat is the branching of wheat, which is one of the important characteristics of wheat. The tillering of wheat is centered on the main stem and is formed from bottom to top on the tillering node .

All tillers produced from the tillering nodes of the main stem are called primary tillers, and the tillers regenerated from the primary tillers are called secondary tillers. The growth cycle continues in this way. As long as the conditions are suitable, a wheat seedling can produce dozens or even hundreds of tillers.

Tillering occurs at tiller nodes, which are nodes and internodes of the main stem or tiller buried below the ground, densely packed at the base of the plant stem.

Characteristics: Tillering is a very random situation, ranging from a few to dozens. At present, three to five are the most common. If you go to the field to investigate, you need to dig up the soil and observe carefully. If tillering occurs, the internodes do not elongate, the nodes are dense, and each tillering node can differentiate into tiller buds and secondary roots.
