Check papers on growth developments of wheat plant. It is some what different according to country, available growth factories and cultivar. Regards.
he grain formation period of wheat crops, also known as the grain filling period, begins after the flowering stage and ends at physiological maturity. The exact timing of this period can vary depending on factors such as weather conditions, crop variety, and planting date.
In general, the grain formation period of wheat crops typically starts around 10-14 days after the start of flowering and lasts for around 30-40 days. During this period, the wheat plant is actively filling the grains with starch and other nutrients, and the grains are increasing in size and weight.
Physiological maturity, which marks the end of the grain formation period, occurs when the grain has reached its maximum dry weight and has stopped accumulating dry matter. At this stage, the grain will have a hard, solid texture and will no longer be able to absorb moisture from the soil.
It's important for farmers to carefully monitor their wheat crops during the grain formation period to ensure that the plants are receiving adequate nutrients and water, as well as to protect the crop from pests and diseases that can damage the developing grains.
In general, the grain formation period of wheat crops typically starts around 10-14 days after the start of flowering and lasts for around 30-40. Physiologically, the stages are: germination, emergence, tillering, floral initiation or double ridge, terminal spikelet, first node or beginning of stem elongation, boot, spike emergence, anthesis and maturity.
