Genetic monitoring in natural perennial plant populations

, 2011
Genetic monitoring, the quantification of temporal changes in population genetics and dynamics metrics generated by using appropriate parameters, constitutes a method with a prognostic value.

Survival costs of reproduction in a short-lived perennial plant: Live hard, die young.

American-Eurasian journal of botany, 2009
According to life-history theory, reproductive investments involve costs in terms of growth, future fecundity, and/or survival. However, studies to date have often failed to detect costs of reproduction, with survival costs among the less documented.

Isolation of Mesoporous Biogenic Silica from the Perennial Plant Equisetum hyemale

, 2008
The structure-conserving isolation of biogenic silica from the perennial plant Equisetum hyemale is investigated using several chemical and thermal treatments.

Controlled Flowering of Herbaceous Perennial Plants

1997
We have determined the juvenility, cold (vernalization), photoperiod, and cultural requirements necessary to flower many herbaceous perennials on specific dates and at specified sizes. We identified the long-day (LD) requirement by conducting critical photoperiod experiments in which critical photoperiod is defined as the photoperiod that elicits a ...

Comparative Analysis of Flowering in Annual and Perennial Plants

2010
In plants the switch from vegetative growth to flowering involves a major transition in the development of the shoot apex. This transition can occur once, in annual species, or repeatedly, in perennial plants. In annuals, flowering is associated with senescence and death of the whole plant, whereas perennials flower in consecutive years and maintain ...

An approach to the growth analysis of perennial plants

Proceedings of the Royal Society of London. Series B. Biological Sciences, 1973
Classical growth analysis is interpreted in the context of perennial plant growth. The inter­pretation was prompted by a long-term field experiment on apple; infrequent tree samples and the deciduous nature of apple prevented the simple quantification of growth relative to the plant’s biomass.

CAUSES OF SYNCHRONOUS FLOWERING IN ASTRAGALUS SCAPHOIDES, AN ITEROPAROUS PERENNIAL PLANT

, 2004
Many plant populations reproduce synchronously over time. Hypotheses to explain reproductive synchrony have typically been based on evolutionary advantages of synchrony, such as increased pollination or decreased predation with increasing numbers of ...

Wood as a Substratum for Perennial Plants in the Southeast

American Midland Naturalist, 1945
The forests of the Coastal Plain, with their high rainfall and long growing seasons, provide many unique places where seeds may find a favorable habitat in which to germinate. Seed plants ordinarily terrestrial have been found rooting in fallen logs, sawed stumps, natural stumps or "snags" left by fire, trees killed by lightning, dead tops or "stag ...

Lifetime Impacts of Herbivory for a Perennial Plant

Ecology, 1992
In spite of widespread interest in the impact of herbivores on plants, few studies have addressed the lifetime consequences of attack for perennial plants. I have addressed this issue by studying the interaction between dwarf fireweed, Epilobium latifolium, and its principal herbivore in south—central Alaska, Mompha albapalpella (Momphidae Lepidoptera).
