Morchella sclerotia has the functions of storing nutrition and resisting adverse environment. Sclerotinia sclerotiorum is a phenomenon of cell differentiation during the development of fungi, and it is a manifestation of the transformation of mycelium from one function to another. The structure of Morchella esculenta is similar to that of Tricholoma esculenta, and the upper part of Morchella esculenta is folded and netted, which looks like a honeycomb and tripe, hence the name. It grows in the low-altitude plain area to an altitude of 3,200m, mostly on the humus layer of broad-leaved forest or mixed coniferous and broad-leaved forest, and it is easy to occur in burned areas.
1. Morchella nuclear growth
1, Sclerotinia sclerotiorum formation is an important and necessary stage in the growth history of Morchella. Its basic functions of storing nutrition and resisting adverse environment have been generally recognized by the scientific community. Sclerotinia sclerotiorum is a phenomenon of cell differentiation during the development of fungi, and it is a manifestation of the transformation of mycelium from one function to another.
2. Many researchers pointed out that there are two forms of sclerotia of Morchella: one is developed from primary hyphae; Second, it is developed from secondary hyphae. Although the sclerotia from these two different sources can continue to germinate to form new secondary hyphae, only the sclerotia formed by the secondary hyphae formed by the fusion of hyphae can develop into the fruiting body of Morchella.
3. Many scholars pointed out that the fruiting body of Morchella is not from sclerotia, but from hyphae germinated from sclerotia, and there is no obvious structural difference. Is pseudosclerotia composed of hypha and host tissue * * * or is it composed of hypha that does not come from sporogenous tissue but has eukaryotic function? This concept, then the sclerotia of Morchella should be? Pseudosclerosis? .
Second, why is Morchella called Morchella?
1, Morchella is named after its appearance. Its structure is similar to that of Tricholoma, and the upper part is folded into a net, which looks like a honeycomb and a sheep's belly, hence the name.
2. Morchella is a Morchella fungus of Morchella family, which grows in the low-altitude plain area at an altitude of 3200m, mostly on the humus layer of broad-leaved forest or mixed coniferous and broad-leaved forest, mainly distributed in sandy loam, cinnamon soil and brown soil rich in humus. And it is easy to happen in burning forest land.
Morchella has a long history. The data showed that Morchella was discovered in 18 18. It used to be pure wild. Although there are artificial cultivation techniques, due to its unique medicinal and dietetic value, the price is still expensive and the output is scarce.
