The sclerotia of Coprinus lagopus

Archiv f�r Mikrobiologie, 1970
Sclerotia of Coprinus lagopus were produced in the laboratory and observed microscopically from initiation to maturity. Isolated bulbous hyphal cells appeared below or on the agar surface as the primary sclerotial initials. Short interhyphal cells had expanded lateral walls and increased in number at their isolated locations, and were surrounded by a ...

The fatty acid composition of sclerotia

Canadian Journal of Microbiology, 1970
The fatty acid compositions of sclerotia of Botrytis tulipae, Sclerotinia borealis, and Sclerotinia sclerotiorum produced under specific culture conditions have been compared with those of sclerotia isolated from natural environments. In each organism the lipids of sclerotia isolated from host plants were more unsaturated than those of cultured ...

The production of sclerotia by Sclerotium rolfsii

Transactions of the British Mycological Society, 1965
The effects of various levels of glucose, nitrate, thiamine, potassium and phosphate on the production of sclerotia by Sclerotium rolfsii Sacc. were investigated by appropriate modifications of a synthetic agar medium. In the absence of any one of these nutrients there was either no growth and no sclerotial production (glucose, thiamine), or growth was

Developmental biology of sclerotia

Mycological Research, 1992
Sclerotia are loosely described as morphologically variable, nutrient-rich, multihyphal structures which can remain dormant or quiescent when their environment is adverse and then, when conditions improve, germinate to reproduce the fungus. A narrower concept of sclerotia distinguishes between ‘true sclerotia’ and ‘sclerotioid structures’, with the ...

Micromorphological Features of Sclerotia Grains

2021
The micromorphological features of the interiors of sclerotia grains were examined by scanning electron microscopy and transmission electron microscopy combined with energy-dispersive X-ray (SEM-EDX, TEM-EDX) and micro computed tomography (micro-CT) analyses.

Mycoparasitism of Sclerotia of Sclerotium Cepivorum.

Australasian Plant Pathology, 1989
Four fungal species were recorded in vitro as potential mycoparasites of sclerotia of Sclerotium cepivorum, the causal agent of onion white rot. Parasitised sclerotia appeared shrunken and decayed and failed to germinate. Light and scanning electron microscopy revealed colonisation of the internal structure of the sclerotium by the mycoparasites.

Germination of sclerotia of Stromatinia gladioli

Transactions of the British Mycological Society, 1980
Undamaged sclerotia of Stromatinia gladioli (Drayt.) Whetz. remained dormant in the absence of host plants. In tests with seedlings and plant tissue extracts, sclerotia germinated only in response to host species. The sclerotial germination stimulant was present in Gladiolus root exudate. Under aseptic conditions sclerotia germinated freely without

Ultrastructure of sclerotia of Aspergillus alliaceus

Transactions of the British Mycological Society, 1982
The sclerotium of Aspergillus alliaceus consists of a pseudoparenchymatous medulla of isodiametric elements, 10–15 μm diam, and a rind of three to four layers of ellipsoidal elements, 3–4 × 5–8 μm, with thinner walls. Wall thickness increases considerably during sclerotium development, reaching 2–3 μm in the medulla and 0.5–1 μm in the rind. The outer

Effects of sclerotia of SClerotium cepivorum berk. on soil bacteria. the nature of substances exuded by sclerotia

Soil Biology and Biochemistry, 1971
Abstract Pure culture sclerotia of Sclerotium cepivorum stimulated development of a number of bacteria on agar media. Using Bacillus subtilis and a chemically defined medium it was found that sclerotia could compensate for the absence of a carbon source but not of other constituents.

Testing the viability of fungal sclerotia

Annals of Applied Biology, 1970
SUMMARYSimple methods for producing, handling and testing the viability of sclerotia were used on five fungi, three of which produced sclerotia freely in sand‐maizemeal cultures; the other two did not, and were grown on agar. After air drying, which did not affect viability, sclerotia were buried in the field in bags of nylon fabric.
