FLOWERING IN LEMNA MINOR

Acta Botanica Neerlandica, 1970
SUMMARY A study was made of the photoperiodic induction of flowering in Lemna minor, strain 6573. For comparison some experiments were performed with L. gibba. Like the latter, L. minor, strain 6573, proves to be a typical long-day plant. The critical daylength is about 10.5 hrs in a 24 hrs cycle, the response being, however, very weak.

Turion formation in strains of Lemna minor (6591) and Lemna turionifera (6573,A)

Aquatic Botany, 1987
Abstract Lemna minor L. (strain 6591) and L. turionifera Landolt (strains 6573 and A) respond differently to culture conditions. Turions are produced and the frondsdie in strains grown in Lm medium, while those same strains continue to grow without turion formation when cultured in E medium.

Comparison of Lemna gibba and Lemna minor from the production ecological viewpoint

Aquatic Botany, 1975
The production capacity and competitive ability in two duckweed species (Lemna gibba L. and L. minor L.), both originating from South Bohemian fishponds, are compared. The results of both laboratory and field experiments have proved that the relative growth rate (RGR) of Lemna gibba exceeds that of L. minor.

The Animals of the Lemna Association

Ecology, 1934
This is a study of the small animals in an association of one of the smallest flowering plants, Lemna minor, in the vicinity of Ithaca, N. Y. The dominant animal forms are naturally very small, ranging in size from a fraction of a millimeter to scarcely six millimeters in length.

Morphological differentiation and geographical distribution of the Lemna gibba-lemna minor group

Aquatic Botany, 1975
Abstract A 100 strains of Lemna gibba L. s.l. and 350 strains of L. minor L. s.l. have been morphologically investigated from a collection of living strains. The following characters have been considered (Table I): shape and size of root-cap, shape and size of fronds, structure of the upper surface, gibbosity, innervation, pigmentation and turion

The systems over of double concentric membranes given in relation to forming are brought in the cages of Lemna minor L. from river Zbruch is in the conditions of complex contamination of water by heavy metals. The set correlation is between the dynamics of maintenance in the duckweed of heavy metals and size of radius of her cages, and also expressed ...

Lemna gibba L

In light of the world's energy challenge and the scarcity of traditional energy resources, Morocco is taking the initiative to become an African leader in the water, energy, and food sectors. It is against this backdrop that this research focuses on the way in which biomass can be used as an environmentally-friendly alternative that makes the wheel of ...
