Density-Dependent Plant–Plant Interactions Triggered by Grazing [PDF]
Frontiers in Plant Science, 2019 Plant species performance in rangelands highly depends on the effect of grazing and also on the occurrence of unpalatable benefactor species that can act as biotic refuges protecting neighboring plants from herbivores.

Episodic herbivory, plant density dependence, and stimulation of aboveground plant production. [PDF]
Ecol Evol, 2020 AbstractHerbivory is a major energy transfer within ecosystems; an open question is under what circumstances it can stimulate aboveground seasonal primary production. Despite multiple field demonstrations, past theory considered herbivory as a continuous process and found stimulation of seasonal production to be unlikely.

A simulation study on the interactive effects of radiation and plant density on growth of cut chrysanthemum [PDF]
, 2002 In the present study, we used a photosynthesis-driven crop growth model to determine acceptable plant densities for cut chrysanthemum throughout the year at different intensities of supplementary light.

High Density Apple Planting Systems [PDF]
Journal of the Northeastern Agricultural Economics Council, 1974 Historically, the standard tree set in commercial apple orchards has been 27 trees per acre, planted on 40 foot centers. With this planting system trees tend to become quite large, requiring substantial amounts of labor for pruning, spraying and harvesting. The large amount of vegetative growth on these trees renders much of the innertree fruit bearing

Plant energetics and population density [PDF]
Nature, 1999 Enquist et al. 1 present data from 37 plant species showing that the use of resources by individual plants scales approximately as the 3/4 power of plant mass, as predicted previously from a model of resource use in fractal-like branching structures2.

Late cabbage planting density [PDF]
Selekcija i semenarstvo, 2018 Late cabbage forms a large above-ground mass which requires certain vegetation space in order to thrive. Late cabbage planting density should therefore, start from at least 70 cm inter-row and 50 cm intra-row spacing. Transplanting at the required spacing gives 28.600 plants per hectare.
