“…In contrast the effectiveness of an inductive treatment decreases with age in Chenopodium rubrum and it is the same for Bidens radiata: for instance, at 22°C minimal inductive treatment is 2 long nights for 24 and 48 h old plants, but 4 long nights for 72 h oid plants. For Chenopodium rubrum, the meristem becomes less sensitive to the photoperiodic induction when its mitotic / M.. ^..,, /jr, "^Z^,: ..r'- activity increases (Seidlova and Opatrna 1978),, and Bidens radiata behaves similarly: for instance, the percentage of fiowering decreases abruptly (Fig. 3) when the leaf initiation occurs at the second node, i.e.…”

Plant. 62: 225-230.The response of Bidens radiata Thuill., a short-day plant, to conditions for flower induction changes during the first 96 h after germination: the earlier the induction, the better the flowering response. Flowering is observed without previous vegetative development. An histological study shows that failure to flower is correlated with the development of the primordia of the second node leaves. The antagonism between vegetative and floral development is discussed.Additional key words -Histology, juvenility, photoperiodic induction, temperature. J?. Poulhe, Y. Arnaud and E.

“…It is sensitive to photoperiodic stimulus for flowering as early as at cotyledonary stage (Seidlová and Opatrná 1978), when 6 adequate photoperiodic cycles are sufficient for flower induction. Under the suitable photoperiodic conditions in vitro, plant flowers in 15 d (Živanović et al 1995), and produces seeds in 10 weeks (Mitrović et al 2007).…”

Effect of photoperiod during growth of Chenopodium rubrum mother plants on properties of offspring

Using in vitro culture, we determined the effect of photoperiod during growth of Chenopodium rubrum mother plants on vegetative and reproductive development of offspring. Photoperiod during flowering induction of mother plants (the first 6 d after the germination) has the key influence on seed germination and offspring growth, while offspring flowering and seed maturation is determined by photoperiod their mothers experienced during, and shortly after, flowering induction. The mechanism can be through changes in seed protein pattern which we found dependent on photoperiod experienced by mother plants.

“…They found that axillary buds can be released from an inhibitory influence of the leaves on the main axis, both mature and young ones forming the apical bud, during both flower-inducing and non-inducing photoperiodic regimes. Correlations within the shoot apex in C. rubrum were described and their importance with respect to flowering reported by Seidlov~i and Opatrnfi (1978), Opatrnfi et al (1982) and Seidiovfi (1985). In this study a combination of surgical and photoperiodic treatments was used to gain further knowledge of a possible regulatory role of shoot organ correlations and especially of the role played by apical dominance in the flowering process.…”

Alammd. Correlations within a shoot of Chenopodium rubrum L. ecotype 374 grown under continuous light or photoperiodic flower induction were studied using surgical treatments. Removal of a single pair of shoot organs had a variety of effects depending on position: significant changes in the number of leaf pair on the main axis or in axillary buds and in the height of shoot apices; or no effect on the parameters scored. Flowering was not affected by any of the treatments carried out.Decapitation brought about a significant increase in the number of leaf pairs in axiUary buds and flowering was inhibited in 8-and 9-d old plants. Flowering was not affected in 21-d old plants. The role of shoot organ correlations, especially that of apical dominance, in regulation of flowering in C. rubrum is discussed,
