Chilling and heat requirements for flowering in apricot cultivars

open access: yesActa Horticulturae, 2018
Chilling requirements for breaking dormancy and heat requirements for flowering were studied in 10 apricot cultivars in the region of Belgrade during a 2‑year period. Chilling requirements were determined using the Utah chill unit (CU) model. To determine the date of dormancy breaking, 1-year-old shoots were collected weekly from December to February ...

Deconstructing cold hardiness: variation in supercooling ability and chilling requirements in the wild grapevine Vitis riparia

open access: yesAustralian journal of grape and wine research, 2019
Background and Aims Grapevine production in cool climates is limited by aspects of winter survival and frost risk. Cold hardiness‐related traits are key to future viticultural sustainability as climate variations, including acute cold events and frost ...

Chilling requirements of Paeonia cultivars

Scientia Horticulturae, 2001
Abstract Dormant second year potted plants of Paeonia ‘Coral Sunset’, ‘Monsieur Jules Elie’, and ‘Sarah Bernhardt’ were placed into three chilling regimes (constant 1, 4, or 7°C) for different durations (3, 6, 9, or 12 weeks) to ascertain their chilling requirements for shoot and flower production. Chilling was followed by forcing for up to 5 weeks

Climate Change and Chilling Requirements

2015
Climate change has affected the rates of chilling and heat accumulation, which are vital for flowering and production, in temperate fruit trees (Guo et al. 2014). All economically important fruit and nut tree species that originated from temperate and cool subtropical regions have chilling requirements that need to be fulfilled each winter to ensure ...

Comparison of different models for chilling requirements evaluation of sweet cherry cultivars in a Mediterranean area

open access: yes, 2017
Chilling requirements for breaking dormancy were investigated for two successive years in ten sweet cherry cultivars (‘Black Star*’,‘Burlat’,‘ Canada Giant® Sumgita*’,‘ Ferrovia’,‘ Giorgia’,‘ Lapins’,‘ New Star’, ‘Somerset’,‘ Sweet Early® Panaro 1*’ and

Nut crop yield records show that budbreak-based chilling requirements may not reflect yield decline chill thresholds

open access: yesInternational journal of biometeorology, 2015
Warming winters due to climate change may critically affect temperate tree species. Insufficiently cold winters are thought to result in fewer viable flower buds and the subsequent development of fewer fruits or nuts, decreasing the yield of an orchard ...
