1990 journal article
ADEQUACY OF INTERVAL ESTIMATES OF YIELD RESPONSES TO OZONE ESTIMATED FROM NCLAN DATA
CROP SCIENCE, 30(4), 836–844.
TL;DR:
Three methods of estimating confidence intervals for the parameters of Weibull nonlinear models are examined and it is shown that in two cases the Wald confidence intervals are misleading, but in a third case they are entirely adequate.

INTERCULTIVAR AND INTRACULTIVAR EFFECTS OF SELECTION ON HETEROSIS
CROP SCIENCE, 30(1), 44–49.
TL;DR:
Intracultivar (W) selection, full-sib family selection within each of two cultivars, and intercultivar [R] selection, reciprocal recurrent selection between the two cultivARS, were contrasted for their effects on heterosis.

DYNAMIC-MODELS OF PESTICIDE EFFECTIVENESS
SCHAALJE, G. B. (1990, June). ENVIRONMENTAL ENTOMOLOGY, Vol. 19, pp. 439–447.
TL;DR:
A general procedure for formulating mathematical models of pesticide effectiveness is presented, consisting of a differential equation for deposition and degradation of the pesticide in the environment, a differential equations for intake and clearance of the pesticides by the insects, and a functional equation relating the hazard function of the insects to their curve of pesticide retention.

A DYNAMIC GROWTH-MODEL OF VEGETATIVE SOYA BEAN-PLANTS - MODEL STRUCTURE AND BEHAVIOR UNDER VARYING ROOT TEMPERATURE AND NITROGEN CONCENTRATION
JOURNAL OF EXPERIMENTAL BOTANY, 41(223), 229–241.
MeSH headings : Carbohydrate Metabolism; Carbon Dioxide / metabolism; Environment, Controlled; Hydroponics; Models, Biological; Nitrogen / metabolism; Organ Size; Oxygen Consumption; Photosynthesis; Plant Roots / growth & development; Plant Roots / metabolism; Plant Shoots / growth & development; Plant Shoots / metabolism; Soybeans / growth & development; Soybeans / metabolism; Starch / metabolism; Temperature
TL;DR:
A differential equation model of vegetative growth of the soya bean plant was developed to account for plant growth in a phytotron system under variation of root temperature and nitrogen concentration in nutrient solution and revealed that the model was most sensitive to changes in parameters relating to carbohydrate concentration in the plant and nitrogen uptake rate.

GENETIC AND GERM PLASM STOCKS WORTH CONSERVING
JOURNAL OF HEREDITY, 81(1), 11–16.
MeSH headings : Gene Library; Genetic Variation; Plants / genetics
TL;DR:
There is an international need for germ plasm systems that emphasize the use and employment of materials rather than acquisition and storage, and for base collections to function, they must provide for regeneration, characterization, documentation, and evaluation of their materials.

EFFECT OF GENE CONVERSION ON VARIANCES OF DIGENETIC IDENTITY MEASURES
THEORETICAL POPULATION BIOLOGY, 38(2), 125–148.
MeSH headings : Gene Conversion; Gene Frequency / genetics; Genetic Variation; Genetics, Population; Humans; Models, Genetic; Mutation / genetics; Recombination, Genetic / genetics
TL;DR:
The variances and covariances of digenic descent measures are studied for a two-locus model incorporating mutation, gene conversion, recombination, drift, and finite sampling, with an emphasis on the effects of gene conversion.
