What are the tricotyledons? I found a total of nearly 100 tricotyledons in five species of plants in

What you're seeing is the polycotyledonous phenomenon. Some scholars have discovered tricotyledonous variants of Sunflower, Qincheng, Chinese cabbage, and Caryophyllus.

So far, we have known that the variation in the number of cotyledons in two tetracotyledon plants is indeed due to polyembryonic. Further research is needed on the heritability of this polyembryonic variant. Compared with the two-cotyledonous plants, there was no significant difference in the number of cotyledons and the early growth rate of the two cotyledons.

The mechanism of its production may be different from that of tetracotyledonous plants, i.e., it is not caused by polyembryonic. Slightly faster growth at the seedling stage suggests that tricotyledonous plants may be more competitive (competing for nutrients and space) than dicotyledonous plants. However, there is no discernible difference in the final plant type, and the possible reasons are:

Under the cultivation conditions in the laboratory, the influence of space and light did not allow the advantages of tricotyledon to be brought into play.

In some cases, the mutant trait of polycotyledons is useful, so agronomists and horticulturists try different methods to mutagenesize the trait in order to obtain new crop varieties. In addition, the molecular mechanism of polycotyledon mutation may involve a series of complex developmental processes, such as the establishment of symmetry in the early stage of embryonic development and the gene expression pattern during lateral organogenesis. In-depth understanding of its mechanisms** will help us solve these developmental problems.

The fundamental difference between them is the development of two ** leaves or one ** leaf in the embryo of the seed, two are called dicots, and one is called monocots.

For example, apples and soybeans are dicots; Rice and corn are monocots.

The root system of dicots, which is basically straight, has a well-developed taproot; Many are woody plants, and the stems can be thickened; The leaf veins are reticulated; The root system of monocots is basically fibrous root system, and the taproot is underdeveloped; Mainly herbaceous plants, woody plants are few, and the stems usually do not thicken year by year; The leaf veins are parallel.

Only monocots and dicots are currently found.

Paeonia lactiflora pall), alias separate grass, the prime minister of flowers, belongs to the order of five fruits, and the peony family is a perennial herb of the peony group.

The tubers are born from the lower part of the root neck, fleshy, stout, spindle-shaped or long columnar, thick. The petals of peony are obovate, the flower disc is shallow cup-shaped, the flowering period is 5 to 6 months, the flowers are generally born at the top of the stem or near the apical leaf axils, the original flowers are white, the petals are 5 13. Horticultural varieties are rich in flower colors, including white, pink, red, purple, yellow, green, black and compound colors, etc., with a flower diameter of 10 to 30 cm and hundreds of petals.

The fruit is spindle-shaped, and the seeds are round, oblong, or pointed.

It's alfalfa, or peanuts, and these two leaves are the same, and you can compare them, and there may be fallen seeds that grow. Please check it out.

Lucerne. Alfalfa grass (

Latin scientific name: lotuscorniculatusl), is the common name of alfalfa (medicago) plant, native to Europe and the Americas, with real clover made of fine products, in Europe, America, Southeast Asia popular for a long time, now in South Korea, Japan, is to clover ornaments as the most perfect blessing to friends. Alfalfa grass is a perennial flowering plant.

The most famous of these is alfalfa (medicago sativa), which is used as a pasture grass and is feed for livestock.

I don't know, let's take a clear look.
