Modelling seedling emergence of common lambsquarters in corn

open access: yes, 1998
Timing of weed seedling emergence relative to the crop is a critical factor determining the outcome of weed crop competition. Field and laboratory studies were conducted (1) to determine how tillage and presence or absence of corn affected soil temperature and moisture and, subsequently, common lambsquarters seedling emergence and density in the field,

Influence of light quality on common lambsquarters adaptive strategies

open access: yes, 2006
Invasive weeds can reproduce in a wide range of environments regardless of competition because plastic physiological mechanisms can accommodate prevailing conditions. However, potential adaptive traits responsible for this plasticity are unknown. Common lambsquarters ('Chenopodium album' L.) was used as a model invasive weed because, once native to ...
