“…A rate change of -0.60 indicated that the effect of photoperiod was apparent from flowering to seed set. These results differed from green foxtail in which reproductive development after heading was found to be independent of photoperiod (Swanton et al 1999).…”

“…These parameters increased as photoperiod increased from 8 to 16 h. Influences of photoperiod on duration of reproductive development have also been reported in other dicotyledonous plants such as soy- Table 1 were expressed in terms of development rates (i.e., inverse of duration of development) and compared across phenological stages, we found no differences (P < 0.05) among photoperiod sensitivities (Table 2). This finding agrees with the observation in green foxtail (Swanton et al 1999) and barnyardgrass (Swanton et al 2000) but differs from that of Slafer and Rawson (1996). The latter authors suggested that photoperiod sensitivity varies with growth stage.…”

“…A similar trend was observed in the leaf development of SD plants such as sorghum [Sorghum bicolor (L.) Moench.] and corn (Quinby et al 1973;Warrington and Kanemasu 1983) and in green foxtail (Setaria viridis L.) (Swanton et al 1999). The average rate of leaf appearance of redroot pigweed ranged between 0.26 to 0.27 leaves per day under the shorter (8, 10 and 12 h) photoperiod treatments, whereas the rate of leaf appearance was 0.31 and 0.57 leaves per day under the longer (14 and 16 h) photoperiod treatments, respectively.…”

“…The success of IWM can be enhanced by the development of predictive simulation models, and efforts have been focussed on the development of predictive mechanistic models of weed occurrence (Kropff and Lotz 1992). Knowledge of weed phenology is essential in the development of a realistic and practical weed model (Elmore 1996;Swanton et al 1999). Two types of models have been developed for the prediction of weed occurrence: mechanistic and empirical models.…”

“…The duration of juvenile phase of redroot pigweed was similar to those of some soybean cultivars (Wilkerson et al 1989), corn hybrids (Tollenaar and Hunter 1983) and annual weeds such as velvetleaf (Abutilon theophrasti Medik.) (Patterson 1995), green foxtail (Swanton et al 1999) and barnyardgrass (Swanton et al 2000).…”

. 2000. Effects of photoperiod on the phenological development of redroot pigweed (Amaranthus refroflexus L.). Can. J. Plant Sci. 80: [929][930][931][932][933][934][935][936][937][938]. Mechanistic weed models focus on determining the outcome of weed and crop interference. An understanding of weed phenology is essential for simulation model development. Phenological development is a major factor determining the outcome of weed-crop competition. Growth cabinet studies were conducted to characterize the influence of photoperiod on the phenological development of redroot pigweed (Amaranthus retroflexus L.). Results indicated that redroot pigweed is a quantitative short-day species. Four development phases of redroot pigweed were described according to its response to photoperiod: (1) a juvenile phase of 1.1 d; (2) a photoperiod-sensitive inductive phase of 7.9 d; (3) a photoperiod-sensitive post-inductive phase of 39.9 d; and (4) a photoperiod-insensitive phase of 2.2 d. This information is useful for the development of mechanistic models and for comprehending the distribution and competitive ability of redroot pigweed with crops. The utilization of these results could help in predicting the phenological development of redroot pigweed.Key words: Phenology, mechanistic weed models, juvenile phase Huang, J.

Plant Sci. 80: 929-938. Les modèles mécanistes des infestations de mauvaises herbes se concentrent sur la résultante de la compétitivité entre mauvaises herbes et cultures. La compréhension de la phénologie des mauvaises herbes est un préalable essentiel à la construction de modèles en simulation car le développement phénologique est un facteur de première importance pour l'issue de la compétition mauvaises herbes-cultures. Nous avons conduit des travaux en armoire de croissance pour caractériser l'influence de la photopériode sur la phénologie de l'amarante à racine rouge (Amaranthus retroflexus L.). L'amarante apparaît comme une espèce de jour court quantitative. Nous avons dégagé quatre phases de développement de l'amarante selon sa réaction à la longueur de la photopériode : 1) une phase juvénile de 1,1 j; 2) une phase d'induction florale sensible à la photopériode de 7,9 j; 3) une phase post-induction, sensible à la photopéri-ode de 39,9 j; 4) une phase photo-apériodique de 2,2 j. Ces renseignements sont utiles pour la construction de modèles mécanistes et pour comprendre le mode de répartition spatiale de la mauvaise herbe ainsi que sa compétitivité envers les cultures. Ils pourraient également faciliter la prédiction de son développement phénologique.

Barnyard grass [Echinochloa crus-galli (L.) Beauv] is a competitive C 4 weed species that is widely distributed throughout the world. Although it originated in warm climatic conditions, currently, it is found in Europe as far north as Norway. This study aimed to compare the phenological development of plants from different climatic conditions in varying environmental conditions. To represent the contrasting climatic conditions within Europe, seeds were collected in Norway and Italy, and distributed to the study participants, to be sown at 10 different sites as two common populations. In addition to that, seeds of two to three local populations were collected near each of the sites. The development of the plants was monitored in a pot experiment set up under field conditions. The time to reach heading in the first year of the experiment was 77.6% faster (ranging from 45.9 to 98.3% on average
