Corn Plant Populations

2008
Introduction Corn hybrid genetics change yearly to increase productivity. The newer hybrids appear to possess plant characteristics that allow for higher plant populations. Over the past several years, field trials across the state have found support for higher plant populations in corn.

Asymmetric competition in plant populations

Trends in Ecology & Evolution, 1990
Recently there has been much interest in the hypothesis that competition between individual plants is asymmetric or onesided: larger individuals obtain a disproportionate share of the resources (for their relative size) and suppress the growth of smaller individuals.

History of Plant Population Genetics

Annual Review of Genetics, 1999
▪ Abstract  This review of plant population genetics focuses on the genetic foundations of the processes that have led to documentable improvements in cultivated plants since the earliest domestications took place perhaps 13,000 years ago. Nearly all human civilizations have depended heavily on inbreeding plants (particularly wheat, barley, soybeans ...

Palaeoecology and plant population dynamics

Trends in Ecology & Evolution, 1988
The pollen record of the past 10-20 thousand years is a source of data both on long-term climatic change and on the dynamics of plant populations in response to climatic change. Time sequences of pollen accumulation rates record invasions of tree taxa over 10(1)-10(3) years.

Pachyderms, primates, plants and population

Reproduction, Fertility and Development, 2002
In the past, growth in human population has often been associated with species loss. Current rates of population growth, both globally (1 million more births than deaths every 103 hours) and regionally, pose a threat of additional ecological damage.

Corn Planting Date and Plant Population

Journal of Production Agriculture, 1994
Predictions of yield responses to planting date and plant population in corn (Zea mays L.) are necessary in order to match plant population to a particular planting date, and also to make replant decisions. Much of the published research on these factors is relatively old.

Plant Growth and Population Dynamics

The main purpose of quantitative nematological research is twofold. First, to develop mathematical models that contribute to theory building. Second, for farmers, to achieve optimal financial returns of crops in the presence of plant-parasitic nematodes.
