, 2000 The pathway from the intercalary frond meristem to distal frond portions was blocked in experimental sporophytes of Laminaria digitata in January by cutting 2 or 3 holes (15-25 mm diameter) 5 cm from the base of the frond.

Soil type and season mediated Phytophthora cinnamomi sporangium formation and zoospore release
Australasian Plant Pathology, 2013The capacity of Phytophthora cinnamomi to sporulate and release zoospores in northern jarrah forest bauxite mining soils sampled in summer, winter and spring was determined. Soil types examined were a surface jarrah forest soil, a Bassendean sand and haul road, mine floor silt and a mine bauxite soil.

STUDIES ON THE GENETIC CONTROL OF RESISTANT SPORANGIUM FORMATION IN ALLOMYCES
American Journal of Botany, 1965The diploid sporophyte of the phycomycetous fungus Allomyces arbuscula bears two types of sporangia: thin‐walled, colorless, ephemeral zoosporangia (ZS) and thick‐walled, dark‐brown, resistant sporangia (RS).

Association of bacteria with sporangium formation and breakdown of sporangia in Phytophthora spp
Australian Journal of Agricultural Research, 1974Leachates from different soils extracted at similar moisture potentials varied in their ability to induce sporangium formation, zoospore release and sporangium breakdown in Phytophthora spp. Sporangium production by P. cinnamomi did not occur in soil leachates heated at 40–50°C for 10 min or in soils treated with steam-air at 60° for 30 min.

A Phytophthora species from lucerne, possibly P. megasperma , formed sporangia readily when disks of V-8 juice agar with mycelium were incubated in a shaken inorganic nutrient solution for 24 hr. at room temperature. Adding ethylene-diamine tetra-acetic acid stimulated sporulation markedly on V-8 juice CaCO 3 agar (pH 6·5) but only slightly on V-8 ...

The pathway from the intercalary frond meristem to distal frond portions was blocked in experimental sporophytes of Laminaria digitata (Huds.) Lamour. in January by cutting 2 or 3 holes (15–25 mm diameter) 5 cm from the base of the frond. This procedure resulted in the formation of sori adjacent to the distal edge of the holes within 5–10 weeks.

Light greatly affected the formation, morphology, ontogeny and caducity of sporangia in both Phytophthora capsici and ‘P. palmivora’ MF4. On carrot agar plates, sporulation was enhanced in continuous light, whereas no sporangia formed in the dark. Sporangia formed in the dark when the agar-disc-in-water technique was employed.

The formation of sporangia in Albugo Candida was studied using light and scanning and transmission electron microscopy. Their mode of development is blastic and they are not formed by percurrent proliferation as previously suggested.
