Comparison of the Photosynthetic Capacity between Intact Leaves of Triazine-Resistant and -Susceptible Biotypes of Six Weed Species
TLDR
Differences in photosynthesis between resistant and susceptible biotypes of Polygonum lapathifolium, Poa annua and Solanum nigrum were not significant, and absent in Chenopodium album and Stellaria media.Abstract:
The rate of photosynthesis in intact leaves of a triazine-resistant biotype of Amaranthus retroflexus was about 15% lower than that of a triazine-susceptible biotype. Differences in photosynthesis between resistant and susceptible biotypes of Polygonum lapathifolium, Poa annua and Solanum nigrum were not significant, and absent in Chenopodium album and Stellaria media. The results are brought in relation to the appearance of resistant biotypes in the field.read more

TL;DR: In this article, the authors provide a detailed description of the model INTERCOM and methods to parameterize and evaluate the model using experimental data, and examples are given of how the model can be used to understand the effects of weeds on crops in field situations.

Herbicide Resistance in Weedy Plants: Physiology and Population Biology
TL;DR: The weed population/herbicide model provides an excellent example and susceptible and resistant biotypes, plants, populations, etc, of a given species will be designated as Sand R-, respectively.

An eco-physiological model for interspecific competition, applied to the influence of Chenopodium album L. on sugar beet. I : Model description and parameterization
TL;DR: An eco-physiological simulation model is presented in which competition between crop and weeds is simulated, based upon the underlying physiological processes of distribution of the resources light and water over the species and the manner in which the species utilize the amounts taken up for dry matter production.

Effects on Photosystem II Function, Photoinhibition, and Plant Performance of the Spontaneous Mutation of Serine-264 in the Photosystem II Reaction Center D1 Protein in Triazine-Resistant Brassica napus L.
TL;DR: It is concluded that the replacement of serine by glycine in the D1 protein has a direct effect on PSII function, which in turn causes increased photoinhibitory damage and increased rates of turnover of the D 1 protein.
