Gibberellin and CCC Effects on Flowering and Growth in the Long-day Plant Lemna gibba G3.
The application of gibberellic acid (GA(3)) to the non-rosette long-day plant Lemna gibba G3 at concentrations from 0.1 to 100 mg/l did not induce flowering on short days and inhibited flowering on long days at concentrations of 1 mg/l and higher. On both short and long days GA(3) concentrations above 1 mg/l caused a decrease in frond size and fresh and dry weight, but an increase in the rate o...
متن کاملGrowth response of Lemna gibba L. (duckweed) to copper and nickel phytoaccumulation Effet de l’accumulation de Cu et Ni sur la croissance de Lemna gibba L. (lentilles d’eau)
To assess the tolerance and phytoaccumulation ability of the duckweed Lemna gibba L. to copper (Cu) and nickel (Ni), the aquatic plants were exposed to different concentrations of Cu and Ni (0.1 – 2.0 mg/L) in quarter Coïc and Lesaint solution at pH = 6.0 (± 0.1) and under a daily regime of 12 h light. Copper and nickel were tolerated by L. gibba at concentrations ≤ 0.3 mg/L and ≤ 0.5 mg/L, res...
متن کاملIndole-3-acetic acid metabolism in Lemna gibba undergoes dynamic changes in response to growth temperature.
Auxin is the mobile signal controlling the rate of growth and specific aspects of the development of plants. It has been known for over a century that auxins act as the messenger linking plant development to specific environmental changes. An often overlooked aspect of how this is accomplished is the effect of the environment on metabolism of the major plant auxin, indole-3-acetic acid (IAA). W...
متن کاملGrowth and ultrastructure of Rhodomicrobium vannielii as a function of light intensity.
Cells of Rhodomicrobium vannielii were grown in a controlled environment at several different light intensities. Differential rates of bacteriochlorophyll (BChl) synthesis and specific BChl contents were inversely related to the light intensity. On the other hand, the specific rate of growth-before reaching a maximal value-was directly related to the intensity of the light. Thin sections of cel...
متن کاملNitrogen fixation and growth rates of Trichodesmium IMS-101 as a function of light intensity
The diazotrophic cyanobacterium Trichodesmium is a significant contributor to marine nitrogen and carbon cycles and has been incorporated in biogeochemical ocean circulation models. To date, parameterization of light as a controlling factor for nitrogen fixation has been based on field observations, where factors other than light also affect Trichodesmium physiology. Here we present data on lig...
