How does Cyclamen change from a single flap to a complex flap?

From the point of view of petal evolution, many flower stamens are often found in nature, especially under artificial cultivation conditions. That is, stamens become petaloids, and sometimes petal also produces natural hyperplasia. The number of ornamental petal is from With much development, there has been a course from a single valve to a double valve (half double valve) to a double valve flower, reflecting the tendency of the pattern from simple to complex.

From the perspective of morphogenesis, the above cyclamen originated from a single lobe to a complex lobe in three origins:

One is the accumulation of origin. The number of petals of a single flower is generally fixed, but occasionally there are individual plants that increase or decrease one or two petals. After several generations of artificial selection, the number of flowers increases from generation to generation until a double and double petals are formed. Flower; but this pot of cyclamen does not have the possibility of artificially increasing the number of petals from generation to generation. This source method can be eliminated.

The second is the origin of the sleeve. Commonly found in the flowers of the flowers, their stamens, pistil, and sepals have not changed in their structure. The corolla is in the form of a sleeve with two to three layers. The cyclamen is a zygomatic flower. The number of stamens is normal, and the petals of its inner edge are likely to originate from the sleeves of the flowers.

Three are the origin of the stamen and stamen. The male pistils of many ornamental plants can evolve into petaloids, thus increasing the number of flower petals to form double or double petals. Sometimes stamens that have not yet fully petrified can be seen in the center of some varieties; some flower varieties have pistil Valvularization also occurs. This cyclamen planted flowers continuously for 4 years to 5 years, and the number of petals increased gradually. If the cyclamen's traits of reduced number of stamens are observed correctly, it does not exclude the possibility that the stamens evolve into endoplasmic petal. However, according to my observation, under normal circumstances, the degree of petalization is not high for the Cyclamen's re-valve is also inseparable from the superior artificial cultivation conditions, because the ornamental plant's double valve, to a certain extent by the plant's own growth potential, Due to the influence of nutritional conditions, cultivation conditions, and place factors, the complex and double-flowering nature of flowers is actually a combination of basic and environmental factors.
