A sorus (pl.: sori) is a cluster of ... As the sporangia mature, the indusium shrivels so that spore release is unimpeded. The sporangia then burst and release the ...
The resilient nature of the resting spores, the overwintering sporangia, is the principal challenge in managing the disease. Several means of control have been explored, including chemical [9] [10] and biological, [11] but have been largely ineffective, impractical, or neglected. Cultivation of resistant varieties is the best management approach.
An envelope forms around the cluster of sporangia and the cluster becomes a sorus. The sporangia release zoospores that infect other cells. These develop into resting spores that will overwinter. Upon germination, the resting spores function as prosori. [1] Karling included the genus Micromyces within this subgenus [1] while other authors do ...
A sporocarp is a specialised type of structure in the aquatic ferns of the order Salviniales whose primary function is the production and release of spores. [1] Sporocarps are found only in the Salviniales, a group that is aquatic and heterosporous, but the structures are very different in the two families of the order. [2]
The genus Phlebodium is exemplified by containing rows of areoles that lack included veins, and each sorus served by two different veins. Correll and Correll, two authors responsible for thirty years of classification since Flora was introduced in 1982, documented Phlebodium aureum as Polypodium aureum as recently as 1982.
Each sorocarp consists of both a sorophore (stalk) and a sorus. [1] [2] Sorocarps release spores. References This page was last edited on 9 October ...
The mature sporangia have a wall that is just a single cell thick, [8] and are typically covered with a scale called the indusium, which can cover the whole sorus, forming a ring or cup around the sorus, or can also be strongly reduced to completely absent. Many leptosporangiate ferns have an annulus around the sporangium, which ejects the ...
