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 ...

Integrated model and field experiment to determine the optimum planting density in plastic film mulched rainfed agriculture

Agricultural and Forest Meteorology, 2019
Ridge–furrow mulching with plastic film is widespread in northern China because it can significantly improve crop yields. Whether maize grain yield would further increase with higher plant density, due to the better soil moisture conditions under plastic

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.
