“…Three phases describing flowering progress were used in SOYDEV: (1) pre-induction (emergence to V 0 ), (2) induction (V 0 -R 0 ), and (3) post-induction (R 0 -R 1 ). This three phases concept of progress toward flowering was suggested by Shanmugasundaram and Tsou (1978), Ellis et al (1992), Collinson et al (1993), and Upadhyay et al (1994), and is also used in another soybean phenology model (Hodges and French, 1985). Further studies across a wider range of conditions are needed to confirm the post-induction insensitive to photoperiod and to identify the appropriate phases of floral induction.…”

“…The different daylength definition used in SOYDEV for postflowering versus floral induction phases suggests that the presumed post-flowering developmental response to daylength may involve a distinct underlying mechanism other than that of floral induction. The use of civil twilight to describe the effect of daylength on floral induction was suggested by Downs and Thomas (1990) and was used in an experiment investigating photoperiod sensitivity in soybean (Ellis et al, 1992). Daylength based on solar elevation of −0.83° was used for the post-R 1 phase as results from this series of experiments indicated a more accurate phenology simulation was achieved using this daylength definition (data not shown).…”

“…The duration of juvenile phase was determined using a method similar to those employed by Kiniry et al (1983), Wilkerson et al (1989), and Ellis et al (1992). A series of paired data sets were generated by splitting data (individual replicates) at the 3, 6 and 9 DAE treatments.…”

. 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.

Control of soybean flowering time is important for geographic adaptation and maximizing yield. Plant breeders have identified a series of genes (E genes) that condition time to flowering; however, the molecular basis in the control of flowering by these E genes, in conjunction with canonical flowering-time genes, has not been studied. Time to flowering in near-isogenic lines (NILs) at the E1 locus was tested using a reciprocal transfer experiment under short day (SD) and long day (LD) conditions. Beginning 8 days after planting, three plant samples were harvested every 3 h for a 48-h period. RNA was isolated from these plants, and RNA samples were pooled for each line and each time period for cDNA synthesis. RT-PCR analysis was performed using primers synthesized for a number of putative flowering-time genes based on homology of soybean EST and genomic sequences to Arabidopsis genes. The results of the reciprocal transfer experiment suggest that the pre-inductive photoperiod-sensitive phase of the E1 NILs responsible for inducing flowering is perceived as early as 5-7-day post-planting. No gene expression differences were found between the E1 and e1 NILs, suggesting that the E1 gene does not directly affect the flowering-time genes during the time period tested; however, differences were observed in gene expression between SD and LD treatments for the putative soybean TOC1, CO, and FT genes. The gene expression results in this study were similar to those of flowering-time genes found in other SD species, suggesting that the selected genes correspond to the soybean flowering-time orthologs.
