Abstract

The temperature requirements of dormant buds are crucial physiological factors determining the genotype-dependent blooming time in Japanese apricot (Prunus mume), and affect pollination efficiency and subsequent fruit crop production.
Because the environmental conditions during bud dormancy and blooming have been changing due to global warming, breeding of new cultivars with various blooming times is required.
To achieve this, precise quantification of the temperature requirements of each cultivar is necessary.
However, it is largely unknown in most P. mume collection in Japan.
In this study, both chilling and heat requirements for the release of endodormancy and ecodormancy, respectively, of 58 P. mume genotypes are evaluated by bud break test using shoot cuttings under forcing conditions.
First, endodormancy release time was estimated using chronologically sampled shoots.
The chilling requirement of each genotype was calculated by the development index (DVI) model we previously established in ‘Nanko’. Next, after exposure to 3°C for genotype-dependent hours of chilling requirements, shoots were incubated at 15°C. The heat requirements were determined as hours at 15°C to reach three gradual bud development stages; 1) buds were loosened, 2) petals became visible, and 3) flowers were open.
Results indicated that P. mume collection used in this study showed wide-ranged chilling (81-1061 h at 3°C for endodormancy release) and heat (695-1174 h at 15°C to flower open stage) requirements.
In addition, a significant negative correlation was observed between chilling and heat requirements for the flower open stage.
In conclusion, this study determined the chilling and heat requirements of P. mume Japanese collection for the first time, which may contribute to further genetic analyses and breeding programs of P. mume cultivars that can adapt to climate change.
