“…A growth chamber study supports these results and also shows that fertile fronds have a nutrient depletion effect on vegetative fronds (Prange 1980). Ostrich Fern sporophytes grow better when supplied with nitrate rather than ammonium (Prange and Ormrod 1982). Nitrogen applied only as ammonium has a deleterious effect on frond water relations and growth.…”

Matteuccia struthiopteris (L.) Todaro is a fern which occurs throughout the north temperate and sub-boreal zones of the northern hemisphere including all provinces and territories of Canada, the northern U.S., Japan, China, Siberia west to Scandinavia, Belgium, France and parts of the Alps. Its occurrence may be considered as an indicator of moist eutrophic soils where the water table is generally within 1.5 m of the soil surface. The young vegetative fronds or "'fiddleheads" that emerge in the spring have beena traditional part of the diet of the Malecite Indians of New Brunswick. These fiddleheads are an edible, nutritious vegetable that is considered to have potential as a cultivated crop.

“…Fertilization appeared to increase the number and possibly the size of the primordia that developed into mature fronds. However, Prange and Ormrod (1982) showed that fertilization did not increase the nutrient content of individual fronds. Fertilization did not increase the number of primordia initiated in the year that the fertilizer was applied, since 4 yr after the treatment, the same number of fronds were produced by U-F and U-NF crowns.…”

“…According to von Aderkas and Green (1986): "M. struthiopteris behaves very much as a forest understorey species, and not as a gap or open site species." However, many studies with M. struthiopteris have been conducted under high light conditions in a greenhouse or under intermediate light conditions in growth cabinets with no apparent damage to the plants (Prange 1980;Prange and Ormrod 1982;Prange et al 1983;Dykeman 1985). Since M. struthiopteris does grow under a variety of light conditions, it probably takes advantage of high light in natural settings.…”

Bergeron, M. E. and Lapointe, L. 2001. Impact of one year crozier removal on long-term frond production in Matteuccia struthiopteris. Can. J. Plant Sci. 81: [155][156][157][158][159][160][161][162][163]. Matteuccia struthiopteris (L.) Todaro populations that had been subjected to crozier harvesting over the past 25 yr were investigated. The number of crowns harvested and the number of croziers harvested per crown varied annually, but most crowns were harvested at least once over 5 yr. In 1995, total and 50% defoliation impacts were tested on subsequent years' frond production in understorey and open site populations. The effect of mineral fertilization on the understorey population was also investigated. Crowns in the open habitat produced more fronds annually than the understorey crowns and were less susceptible to partial defoliation. One year with total defoliation was sufficient to significantly reduce the number of fronds produced in both habitats over the next 4 yr. Defoliated crowns also accumulated less carbohydrates at the end of the first season. Mineral fertilization increased the number of fronds produced the following year but had no long-term benefit and did not significantly alleviate defoliation effects. Despite the fact that harvesting intensity was relatively low, it appears necessary to limit crozier harvesting per crown to less than 50% in understorey populations to preserve wild populations of M. struthiopteris. Todaro étudiées subissent la cueillette des frondes depuis 25 an. Le nombre de couronnes subissant la cueillette de même que le nombre de frondes récoltées par couronne varie d'une année à l'autre mais la plupart des couronnes sont soumises à au moins une cueillette à tous les 5 an. En 1995, nous avons testé l'impact d'une défoliation totale et à 50 % sur la production de frondes au cours des années subséquentes dans une population située en sous-bois et une population située en milieu ouvert. L'impact d'une fertilisation combinée aux mêmes traitements de défoliation a également été testé en sous-bois. Les couronnes en milieu ouvert ont produit plus de frondes annuellement que les couronnes en sous-bois et sont moins susceptibles à une défoliation partielle. Une seule année de défoliation complète a été nécessaire pour réduire de façon significative le nombre de frondes produites dans les deux habitats au cours des 4 an suivantes. Moins de réserves de carbone ont également été accumulées à la fin de la première saison chez les couronnes défoliées. La fertilisation a augmenté le nombre de frondes produites l'année suivante mais n'a pas montré d'impact à long terme et ne permet pas de compenser les effets de la défoliation. Malgré le fait que l'intensité de cueillette est relativement faible, il semble nécessaire de réduire à moins de 50 % le nombre de frondes récoltées par couronne dans les populations situées en sous-bois si l'on veut maintenir ces populations à long terme.
