Ecological Effects of Barnyardgrass on Soybeans in a Greenhouse
Weed Science, 1977Greenhouse studies were conducted to study the competition between soybeans [Glycine max(L.) Merr. ‘Vansoy’] and barnyardgrass [Echinochloa crus-galli(L.) Beauv.]. The competition was initiated or terminated when soybeans were 2, 3, 4, 5, 6, 7, 8, 9, and 10 weeks old.

Effects of Temperature and Photoperiod on the Phenological Development of Barnyardgrass
Agronomy Journal, 2000An understanding of the environmental variables influencing the phenological development of weeds is essential for simulation model development. Temperature and photoperiod are important variables governing the phenological development of weeds.

Atrazine-Induced Ultrastructural Changes of Barnyardgrass Chloroplasts
Weed Science, 1968Electronmicrographs of barnyardgrass (Echinochloa crusgalli (L.) Beauv.) grown under controlled conditions and treated with 2-chloro-4-ethylamino-6-isopropylamino-s-triazine (atrazine) at the one to three-leaf stages show that degradation of the chloroplast starts as a swelling of the fret system followed by swelling and disruption of the granal discs.

[Genes mapping on rice allelopathy against barnyardgrass].
Ying yong sheng tai xue bao = The journal of applied ecology, 2004By using the relay seeding technique with slight modification, a population of 134 recombinant inbred lines (RILs) derived from a cross between indica rice (Oryza sativa L.) cultivar Zhong 156 x Gumei 2 and contained 168 DNA markers covering all 12 chromosomes with 1447.9 cM spans was employed to evaluate the rice allelopathic effect on barnyardgrass ...
