You might think that Epiphany is the flower with the shortest lifespan, but this is not the case. The flowering time of Epiphany is three to four hours. However, wheat flowers will fade after only five to thirty minutes, so the life span of wheat flowers is the shortest in the world.
The structure of the shortest-lived flower in the world
The flowers of wheat are arranged in compound spikes, usually called wheat spikes. Wheat ears are composed of two parts: cobs and spikelets. The cob is upright without branching, and contains many nodes, with one spikelet on each node. Spikelets contain 2 glumes and 3-9 small flowers. Wheat flowers are bisexual, composed of 1 lemma, 1 lemma, 3 stamens, 1 pistil and 2 lodicules. Because of the different varieties of its lemma, some varieties have awns and some have no awns.
The flowering time of the shortest-lived flower in the world
If the temperature of wheat is normal after heading, it will bloom after 3 to 5 days; when wheat ears that are drawn late are exposed to high temperature, they will often bloom within 1 to 2 days after heading, or even the day of heading; if low temperature is encountered after heading, then It takes 7-8 days or even ten days to bloom.
In normal weather, wheat blooms most in the morning, less in the afternoon, and rarely in the early morning and evening. Therefore, the morning is the best time to collect pollen and pollination, while the best time to emasculate the female parent is in the early morning and evening. The flowering time of a flower is generally 15-20 minutes.
The flower with the shortest life span in the world and its flowering order
As far as the whole plant is concerned, the wheat ears on the main stem open first, and the wheat ears on the tillers open later; for one wheat ear, the middle spikelet opens first, and the upper and lower spikelets open later; just one For spikelets, the flowers at the base bloom first, and the flowers at the upper bloom later.
