“…There was a positive response to a cold treatment at the seedling stage. These results confirm the observations of Sampson & Burrows (1972) that the response to cold treatment is not obligatory as in winter wheat, but that there was a quantitative response. The untreated Solva plants were higher tillering than the flowering Solva plants and the leaves had a more fleshy appearance.…”

“…The results clearly demonstrated that winter oat cultivars did respond to vernalisation although it was not essential to flowering, confirming the conclusion of Sampson & Burrows (1972) that 'cold requirements are quantitative rather than obligatory in Avena plants'. The monosomic analysis response to vernalisation was shown to be a recessive character and that at least 4 chromosomes had some effect with chromosome XVIII being the most potent.…”

“…Although winter oats will flower and produce a crop when sown in the spring it has been shown by Sampson & Burrows (1972) that they do respond to vernalisation. They demonstrated that the response to long day and cold requirements were quantitative rather than obligatory in Avena since they would flower eventually if given a sufficiently long growing season.…”

“…They also refer to Sampson and Burrows (1972) that the requirement of vernalization in the case of winter oats is more facultative than obligatory. We tested the reaction to vernalization of the above-mentioned varieties Solva and Kymon in the next collection, together with the varieties Gerald and Pendragon, and a very low effect of low temperatures was proved again for the Pendragon variety 10 days, for the Kymon and Solva varieties 1020 days, and for the Gerald variety 2030 days.…”

We evaluated the need for low temperatures (vernalization) and the photoperiodic reaction of three collections of winter oats (1. Pedarn, Maris Quest, Peniarth; 2. Gerald, Solva, Kymon, Pendragon; 3. Pewi, Silwi, Wiskas) in a comparison with spring oats varieties. All three collections of varieties showed little need for low temperatures, mostly as few as 1020 days, which does not represent an obligatory need; this influence is only quantitative and constitutes no precondition for a passage of plants into the generative stage. Only in the case of the Maris Quest variety, the need for vernalization approached 30 days. As compared with the reaction of winter barley varieties that had and in some cases still have worse overwintering in the Czech Republic, the length of vernalization is equal. In the photoperiodic experiment, the reaction to a short autumn day turned out to be the critical condition for a possibility of autumn sowing and overwintering; in the case of these varieties, a short day inhibits the development until arrival of winter. We evaluated this reaction according to the length of the induction period. This period was only 1015 days in the case of the spring oats Èeský lutý, 30 days in the case of winter oats Maris Quest, 25 days for Pedarn, 20 days for Peniarth and 21 days for Pendragon; the induction period was 1421 days in the case of varieties Gerald, Kymon and Solva. When compared with figures for winter barley, it had the longer photoperiodic induction period. The evaluated varieties of winter oats do not reach such a degree of a reaction to a short day, which manifests itself in their lower frosthardiness than that of winter barley. We verified that in provoking tests for frosthardiness, and also by lower critical values of temperatures for dying out of 50% of plants, the so-called LT 50.

“…A low temperature (0Á108C) vernalization requirement, typically 4Á8 wk, is observed in many plant species adapted to temperate climates (Sampson and Burrows 1972;Myers et al 1982;Griffiths et al 1985). Kahangi et al (1996) found a cumulative response in Daucus carota L. when artificial cold treatments were used to supplement natural chilling; long vernalization periods increased the percentage of plants that flowered and decreased days to flowering, compared with plants exposed to short cold periods.…”

Harvest date, post-harvest vernalization and regrowth temperature affect flower bud induction in Russian dandelion (Taraxacum kok-saghyz)

. 2015. Harvest date, post-harvest vernalization and regrowth temperature affect flower bud induction in Russian dandelion (Taraxacum kok-saghyz). Can. J. Plant Sci. 95: 1221Á1228. Russian dandelion (Taraxacum kok-sagyz Rodin; TKS) is a promising candidate for introducing natural rubber production into North America; however, a comprehensive analysis of factors that influence flowering is essential for efficient breeding and crop development. The objectives of this study were to determine the effects of fall harvest date (early September, October and November), post-harvest vernalization (0, 4 and 8 wk at 48C), and greenhouse regrowth temperature 1/18 8C. La vernalisation n'est pas essentielle a`l'induction de la floraison; 80 a`100 % des plantes fleurissent peu importe le traitement. On combinera de diverses fac¸ons la date de la re´colte, la pe´riode de vernalisation et la tempe´rature a`la repousse pour maximiser la floraison du pissenlit russe et avoir une incidence positive sur le de´veloppement du mate´riel ge´ne´tique.
