  • Plant Density, Plant Form and Community Diversity

    effects of density do not fall equally on all parts of a plant. In general the size of parts (e.g., leaves or seeds) is much less plastic than the number of parts (e.g., branches). The stress created by the proximity of neighbors may be absorbed in an increased mortality risk

  • What is Density?

    Density is sometimes mistakenly thought to be an estimate of plant cover or biomass. However, plants can vary substantially in size which can lead to weak relationships between density and cover. For example, density of juniper trees per hectare could include little trees that are just a few meters tall and very large trees that are more than 5 meters tall covering several square meters.

  • A method to estimate plant density and plant spacing

    May 17, 2017Plant density at emergence is governed by the sowing density and the emergence rate. For a given plant density, the uniformity of plant distribution at emergence may significantly impact the competition among plants as well as with weeds [1, 2]. Plant density and uniformity is therefore a key factor explaining production, although a number of species are able to compensate for low plant densities by a comparatively significant development of individual plantsCited by: 7

  • Plant Density Effects on Growth, Yield and Yield

    Plant density is an important agronomic factor that manipulates micro environment of the field and affects growth, development and yield formation of crops. Within certain limits, increase of Plant Population Density (PPD) decreases the growth and yield per plant but the reverse occurs for yield per unit area (Caliskan et al., 2007).

  • Density of Plastics Material: Technical Properties Table

    Density measures the mass per unit volume.It is calculated by dividing the mass of the material by the volume and is normally expressed in g/cm 3. The density of a plastic sample may change due to change in crystallinity, loss of plasticizers, absorption of solvent, etc. It is important to note that density varies with temperature. Therefore, to determine the exact density of plastic, it is
