Effect of Hirschmanniella caudacrena on the Submersed Aquatic Plants Ceratophyllum demersum and Hydrilla verticillata.
In vitro pathogenicity tests demonstrated that Hirschmanniella caudacrena is pathogenic to Ceratophyllum demersum (coontail). Symptoms were chlorotic tissue, deformed stems, and, finally, death of the plant. Inoculum densities of 500 nematodes per 5-cm-long cutting in a test tube containing 50 ml of water resulted in death and decay of some of the cuttings within 8 weeks; 100 nematodes killed t...
متن کاملColonization, regeneration potential and growth rates of fragments of the exotic aquatic macrophyte Hydrilla verticillata
Hydrilla verticillata is an aquatic macrophyte recently found in the Upper Paraná River floodplain. This species has a high potential to reproduce and disperse to new sites, mainly through stem fragments. In this study, we evaluated the colonization (the ability of roots to develop), regeneration (the ability of lateral shoots to develop) and growth rates of this species using fragments of diff...
متن کاملEffects of nitric oxide on zinc tolerance of the submerged macrophyte Hydrilla verticillata
Heavy metal pollution has become an increasingly recognized threat to the aquatic environment. In response to heavy metal stresses, various terrestrial plants produce the hormone nitric oxide (NO), but minimal information is available about the role of NO in aquatic macrophytes under high zinc (Zn) stress. In this study, we measured physiochemical parameters in the leaves of Hydrilla verticilla...
متن کاملEffect 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...
متن کاملERDC/TN APCRP-BC-32 "Genetic Relationships among Invasive Hydrilla (Hydrilla verticillata L.f. Royle) Biotypes in the US and Their Implications for Management"
INTRODUCTION: Hydrilla verticillata L.f. Royle (hydrilla; Hydrocharitaceae), an invasive submersed plant native to Southeast Asia and Australia, was first introduced into the US through the aquarium trade in Florida in the 1950s (Schmitz et al. 1991). Hydrilla impacts freshwater resources in the US by its aggressive, canopy-forming growth that degrades aquatic ecosystems, limits recreation, fou...
