Characterization of environmental effects on flowering and plant architecture in an everbearing strawberry F1-hybrid by meristem dissection and gene expression analysis. Horticulturae
Samad, Samia; Rivero, Rodmar Isak; Kalyandurg, P. B.; Vetukuri, R. R.; Heide, Ola M.; Sønsteby, Anita; Khalil, Sammar (Peer reviewed; Journal article, 2022-07-22)Floral transition in the cultivated everbearing strawberry is a hot topic because these genotypes flower perpetually and are difficult to maintain in a non-flowering state. However, it has rarely been studied using ... -
Dynamics of dormancy regulation in ‘Sonata’ strawberry and its relation to flowering and runnering
Sønsteby, Anita; Heide, Ola M. (Journal article, 2021-01-22)Background Dormancy regulation in strawberry is a dynamic process that is causally interrelated with regulation of flowering. Interference between the two processes is therefore possible. Methods We studied dormancy control ... -
Effect of temperature and photoperiod preconditioning on flowering and yield performance of three everbearing strawberry cultivars
Rivero, Rodmar Isak; Remberg, Siv Fagertun; Heide, Ola M.; Sønsteby, Anita (Peer reviewed; Journal article, 2022-06-06)Environmental control of flowering in everbearing strawberry is well known, while the optimal commercial raising conditions for high and continuous yield remains unsettled. We exposed freshly rooted plants of cultivars ... -
Effects of runner removal and partial defoliation on the growth and yield performance of ‘Favori’ everbearing strawberry plants
Sønsteby, Anita; Woznicki, Tomasz; Heide, Ola M. (Peer reviewed; Journal article, 2021-07-29)It is not known to what degree growth and fruit yield are source-limited in everbearing strawberry plants. The growth and yield performance effect of bi-weekly removal of all runners and/or one or two leaves during the ... -
Environmental regulation of dormancy, flowering and runnering in two genetically distant everbearing strawberry cultivars
Rivero, Rodmar Isak; Remberg, Siv Fagertun; Heide, Ola M.; Sønsteby, Anita (Peer reviewed; Journal article, 2021-08-29)The environmental control of dormancy and its relation to flowering and runner formation is poorly understood in everbearing (EB) strawberry cultivars. We studied the topic by growing plants of the seed-propagated F1-hybrid ... -
Extreme short-day induction requirements for flowering in the late-flowering strawberry cultivar ‘Malwina’
Sønsteby, Anita; Heide, Ola M. (Peer reviewed; Journal article, 2019-10-16)We studied short-day induction of the strawberry (Fragaria x ananassa Duch.) cultivar ‘Malwina’ under both phytotron and field conditions. Flowering was assessed by crown dissection of treated plants and subsequent flowering ... -
Floral initiation in gooseberry (Ribes uva-crispa L.) and its control by daylength and temperature
Sønsteby, Anita; Rivero, Rodmar Isak; Woznicki, Tomasz; Heide, Ola M. (Peer reviewed; Journal article, 2022-01-27)The morphogenetic changes of the bud meristem during floral initiation in gooseberry were examined by scanning electron microscopy. Six floral stages, similar to those reported for black currants, were identified. We also ... -
Flowering Phenology of Six Seasonal-Flowering Strawberry Cultivars in a Coordinated European Study
Krüger, Erika; Woznicki, Tomasz; Heide, Ola M.; Kusnierek, Krzysztof; Rivero, Rodmar Isak; Masny, Agnieszka; Sowik, Iwona; Brauksiepe, Bastienne; Eimert, Klaus; Mott, Daniela; Savini, Gianluca; Demene, Marino; Guy, Karine; Petit, Aurelie; Denoyes, Béatrice; Sønsteby, Anita (Peer reviewed; Journal article, 2022-10-11)The flowering phenology of six genetically distant strawberry cultivars (‘Candonga®’ (ES), ‘Clery’ (IT), ‘Florence’ (UK), ‘Frida’ (NO), ‘Gariguette’ (FR), and ‘Sonata’ (NL)) was studied for 3 years in relation to climatic ... -
Flowering physiology and cold resistance of Potentilla palustris (L.) Scop., a wild relative of the strawberry
Heide, Ola M.; Sønsteby, Anita (Journal article; Peer reviewed, 2015)Environmental control of growth and flowering and the freezing tolerance of two Norwegian populations of Potentilla palustris (L.) Scop. were studied under controlled environment conditions. Under short day (SD; 10 h) ... -
Functional growth analysis of ‘Sonata’ strawberry plants grown under controlled temperature and daylength conditions
Sønsteby, Anita; Solhaug, Knut Asbjørn; Heide, Ola M. (Journal article; Peer reviewed, 2016-08-17)In order to investigate the relationship between environmental conditions and vegetative growth and reproductive development in the strawberry, freshly rooted runner plants of the cultivar ‘Sonata’ were grown in a phytotron ... -
