“…Such cultivars usually produce a few flowers and fruits at the tip of the shoot at the end of the first growing season, while the remainder of the buds will flower and fruit in the second year. However, this type of behaviour can be found in both annual-and biennial-fruiting cultivars (Williams, 1960;Carew et al, 2000) and, as demonstrated by , it is a plastic trait that, to a large extent, is under environmental control (cf. Slate, 1940;Ourecky, 1976).…”

“…The breeding history of this latter group, which has involved crosses with other Rubus species such as R. arcticus, R. odoratus, R. spectabilis and others, has been reviewed by Keep (1988). In addition, a third, intermediate, so-called tipflowering type is sometimes considered (Carew et al, 2000;Dale, 2008). Such cultivars usually produce a few flowers and fruits at the tip of the shoot at the end of the first growing season, while the remainder of the buds will flower and fruit in the second year.…”

Heide (2010) Earliness and fruit yield and quality of annual-fruiting red raspberry (Rubus idaeus L.): Effects of temperature and SUMMARY Earliness, fruit yield and quality of six annual-fruiting raspberry (Rubus idaeus L.) cultivars were tested under protected cultivation in a cool Nordic environment. After raising plants for 5 weeks in greenhouses with average mean temperatures of 20°C, 22°C, or 26°C, the plants were cropped in an open plastic tunnel at latitude 61°N. The highest yielding cultivars were 'Autumn Bliss' and 'Polka', with 640 g plant -1 .Overall, the most promising cultivar was 'Polka' which combined high yield with large fruit of good flavour and firmness. In earliness, 'Polka' was surpassed only by 'Autumn Bliss', which confirmed its position as the earliest commercial annual-fruiting cultivar. However, 'Autumn Bliss' had soft fruits with little flavour and a short shelf-life, which greatly reduced the potential of the cultivar for the fresh fruit market. The later ripening cultivar 'Erika' did not complete its crop under these conditions, but its large unrealised yield potential and good fruit quality rendered it extremely promising for environments with a longer growing season. 'Sugana' was late, with low yields and poor fruit quality, while 'Marcela' did not yield enough fruit to be of interest under the present conditions. High temperatures during the 5-week raising period generally advanced flowering and fruit ripening in all cultivars, with the notable exception of 'Autumn Treasure' in which flowering was suppressed and strongly delayed by high temperature. Under the present conditions, there was a highly positive correlation between earliness and fruit yield. Regression analyses identified a low number of dormant buds as the single most important component of plant architecture associated with high fruit yield, accounting for 47% of the total variation.

“…Old canes or canes developed from replacement buds just below the soil were of no use for in vitro initiation culture because of difficulties with disinfecting the material and with flowering in vitro. Both raspberry and black raspberry produce flowers and fruit on 2-year-old wood (Carew et al 2000), and floral evocation of the meristem would have occurred before initiation culture, hence the high degree of flowering and associated death of the explants. Some Rubus species and cultivars are reported to be extremely difficult to culture, with low micropropagation rates.…”

Factors affecting micropropagation efficiency of 32 selections of Rubus, including the pre-treatment and initiation culture stages, were investigated. Chilling at 4°C for 6 weeks as a pre-treatment significantly promoted in vitro initiation culture; up to 65% of initiation cultures post chilling were successful. The cytokinin 6-benzyladenine (BA) was the most effective of the three tested for promotion of multiple shoot development in culture, with an average of three to seven shoots or plantlets developed from each single node. Alternating the concentration of BA between 4.44 and 13.31 lM from sub-culture to subculture improved recalcitrant Rubus micropropagation, and reduced the problems associated with long-term culture in the presence of high concentrations of BA. Reduction of the strength of macro-and micro-elements in the basal medium from half to one-third, with addition of 0.49 lM indole-3-butyric acid and 0.05% activated charcoal, and placing the cultures under reduced light intensity (17 lmol m -2 s -1 ), was found to alleviate chlorosis and improve micropropagation with high quality Rubus plantlets. Response to in vitro culture differed greatly and consequently different methods of micropropagation were required by different genotypes. From these selections, three types of micropropagation including micro-cutting, micro-shoots and multi-shoots were observed, and their efficiency was characterized.

Zusammenfassung Die Bedeutung des prognostizierten Temperaturanstiegs für den Erdbeer-und Himbeeranbau im Freiland wird mittels Literaturübersicht und Temperaturdaten des Standortes Geisenheim, Deutschland, im Hinblick auf Blüteninitiation, Dormanz und Temperaturoptimum der Fotosynthese diskutiert. Bei beiden Beerenobstarten werden sowohl einmaltragende als auch remontierende Sorten betrachtet. Probleme werden zukünftig bei der Blüteninitiation von sommertragenden Himbeeren erwartet, sowie bei der Brechung der Dormanz bei Erdbeer-und Himbeersorten mit hohem Kältebedarf.Der erwartete Temperaturanstieg führt zu einer Verfrü-hung von Blüte und Ernte.Schlüsselwörter Temperaturanstieg · Fragaria x ananassa Duch. L. · Rubus idaeus L. · Blüteninitiation · Dormanz · Kältebedarf · Pflanzenwachstum Temperature conditions as a result of changes in climate and their relevant to the cultivation of straw-and raspberriesAbstract The importance of the predicted temperature increase as a consequence of change in climate on strawberry and raspberry production is discussed with regard to flower initiation, dormancy and temperature optimum for photosynthesis on the basis of a literature review and temperature data from the location of Geisenheim, E. Krüger (u) Forschungsanstalt Geisenheim, Fachgebiet Obstbau, von-Lade-Germany. June-bearing strawberry and biennial fruiting raspberry cultivars and remontant cultivars for both species are considered. In the future, problems will be expected for flower initiation of June-bearing raspberry and for breaking of dormancy of strawberry and raspberry cultivars with high chilling requirement.The predicted temperature increase will lead to early flowering and cropping of the berries.
