Plant density does not influence every castor plant equally

Industrial Crops and Products, 2017
Abstract Castor (Ricinus communis) is an oilseed crop, which oil is used in the chemical industry for several products. There are attempts to adjust the plant density of castor aiming to increase its seed yield. This study discusses how plant density influences seed yield of individual castor plants.

Crop Yield and Planting Density

Annals of Botany, 1983
From the established responses of plants to photosynthetic activity and to the availability of nutrients in the soil, a crop yield : planting density response equation is derived with parameters that are of biological significance. The relationship between crop yield, Y (kg m~2) and planting density, p (number of plants m~2), is of considerable ...

Plant Protoplast Enucleation by Density Gradient Centrifugation

2003
A number of different methods have been developed for the enucleation of cells, particularly mammalian cells. Centrifugation of cells adhering to a surface may lead to the nucleus being drawn out from the cytoplasm, resulting in the formation of an enucleated cell or cytoplast and a nucleus surrounded by a thin layer of cytoplasm bounded by a plasma ...

Importance of plant architecture and plant density for rose crop performance

Journal of Horticultural Science, 1997
SummaryThe relationships between plant architecture and flower production of rose were studied for a cropping period of 2.5 years. Four types of plants, varying in number of basal shoots and their architecture were created, which were combined with three plant densities (7.7–11.6 and 17.4 plants per m2).

Relation between plant density and arthropod density in cabbage fields

Population Ecology, 1999
AbstractThe relationship between plant density and the abundance of arthropods was examined by planting cabbages in four densities (0.25, 1, 4, or 8 plants per square meter). Four herbivorous species were examined: the small white butterfly Pieris rapae crucivora Boisduval, the diamondback moth Plutella xylostella (Linnaeus), the beet semi‐looper ...

Competition-density effect in plant populations

Journal of Forestry Research, 2002
The competition-density effect of plant populations is of significance in theory and practice of forest management and has been studied for long time. The differences between the two reciprocal equations of the competition-density effect in nonself-thinning populations and self-thinning populations were analyzed theoretically.
