Azolla pinnata Growth Performance in Different Water Sources

Polyamine-Induced Rapid Root Abscission in Azolla pinnata

Floating ferns of the genus Azolla detach their roots under stress conditions, a unique adaptive response termed rapid root abscission. We found that Azolla pinnata plants exhibited dose-dependent rapid root abscission in response to the polyamines spermidine and spermine after a substantial time lag (>20 min). The duration of the time lag decreased in response to high pH and high temperature w...

Chemical Composition and the Feeding Value of Azolla (Azolla pinnata) Meal for Egg-Type Chicks

Biochemical and nutritional studies were carried out to evaluate the potential of Azolla (Azolla pinnata R. Brown) meal, AZM, as a feed resource in the diet of egg-type chicks. In a completely randomized design, 30 two weeks old Nera brown chicks were assigned to each of the four dietary treatments containing 0, 5, 10 and 15% azolla meal. Chemical analysis indicated that azolla meal contained (...

Effect of Detergents on the Growth of Two Aquatic Plants: Azolla pinnata and Hydrilla verticillata

The effect of three chemical formulationstwo surfactants, Sodium Lauryl Sulfate (SLS) and Sodium Dodecyl Benzene Sulfonate (SDBS) and a builder Sodium Tripolyphosphate (STPP) on two aquatic plants – Azolla pinnata and Hydrilla verticillata was studied at various concentrations for a period of five months, from November to March. It was observed that while the detergents favoured the growth of p...

Bimodal effect of hydrogen peroxide and oxidative events in nitrite-induced rapid root abscission by the water fern Azolla pinnata

In the genus Azolla rapid abscission of roots from floating fronds occurs within minutes in response to a variety of stresses, including exposure to nitrite. We found that hydrogen peroxide, though itself not an inducer of root abscission, modulates nitrite-induced root abscission by Azolla pinnata in a dose-dependent manner, with 2 mM H2O2 significantly diminishing the responsiveness to 2 mM N...
