Aquatic Botany, 2001 The rate of vegetative propagule development was estimated in three duckweed (Lemnaceae) species, Spirodela polyrhiza, Lemna minor, and Wolffia borealis, by measuring the number of daughter fronds produced over the life span of mother fronds.

Vegetative Reproduction in Western Ironweed
Weed Science, 1969The apex of western ironweed (Vernonia baldwini Torr.) vegetative bud shoots adheres to the tunica-corpus theory. Two layers of cells with the plane of wall formation anticlinal to the main axis (tunica) lie over a body of tissue with no pattern to wall formation (corpus). The bud shoot can be divided into the promeristem, the zone of elongation, and a

Vegetative Reproduction in Conifers
American Midland Naturalist, 1937Vegetative or monogenetic reproduction is not so common in conifers as in woody angiosperms, especially in more favorable habitat sites, yet it occurs even under forest conditions in more species of evergreens than is usually recognized. Apparently it is stimulated by rigorous habitat conditions such as low temperature of arctic and alpine climates ...

VEGETATIVE REPRODUCTION IN CHLOROPHYTUM ELATUM
American Journal of Botany, 1938THE PLANT commonly known as Chlorophytum elatum R. Br. is easily propagated by small plants which develop at the tips and nodal regions of stolons. Scores of such individuals may be found on one mature plant, and no doubt such ease of propagation has helped to make this plant a favorite greenhouse subject. Other members of the Liliaceae, especially the

Robust Optimization by Means of Vegetative Reproduction
2011In the last half century, computer science has witnessed the appearance of nature-inspired methods for the resolution of complex optimization problems, which are hardly solved by traditional optimization methods. Metaheuristics like evolutionary algorithms or swarm intelligence have been successfully applied to a wide range of both theoretical and ...

Transition from vegetative to reproductive phase
Current Opinion in Plant Biology, 2001During the past two years, significant progress has been made towards understanding the molecular basis of how multiple pathways regulating the floral transition are integrated. The transcriptional regulation of several genes, the floral meristem identity gene LEAFY and the 'flowering-time' genes FLOWERING LOCUS T and SUPPRESSOR OF OVEREXPRESSION OF CO

The effect of proflavine on the vegetative reproduction of bacteriophage λ
Molecular and General Genetics MGG, 1969Proflavine in concentrations which had only small effects on the growth rate of the host organism markedly decreased the phage yield from bacteria infected with phage λ gv. The number of bacteria which released infective phage particles was reduced and the bacteria which remained productive released a smaller number of particles/bacterium.

A model for the evolution of self-fertilization and vegetative reproduction
Journal of Theoretical Biology, 1976Abstract It was shown in a simple model that a gene for selfing will be established in a population if and only if at least one of the selfing genotypes also contributes to random fertilization. The same conclusion is valid for vegetative reproduction and ameiotic parthenogenesis.

Vegetative and Reproductive Plant Phenology
2015An analysis of phenological patterns of plant species of the Yucatan Peninsula is presented. Vegetative phenology is analyzed on community level, based on vegetation types of the region. Spatial differences of precipitation availability play an important role in foliar behavior at community level.
