Plant dormancy in the perennial context

Trends in Plant Science, 2007
A key feature of the perennial life style in plants is the ability to cease meristem activity and to establish a dormant state in which the meristem is rendered insensitive to growth-promoting signals for some time before it is released and can resume growth.

Coexistence of perennial plants: an embarrassment of niches

Ecology Letters, 2010
Ecology Letters (2010) 13: 1019–1029AbstractDespite decades of research documenting niche differences between species, we lack a quantitative understanding of their effect on coexistence in natural communities. We perturbed an empirical sagebrush steppe community model to remove the demographic effect of niche differences and quantify their impact on ...

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 ...

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 ...

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.

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).
