Genetic Analysis of Apple Autumn Canopy Senescence in a Nordic Climate
ABSTRACT Autumn phenology traits are likely to be essential for the adaptation of apple to boreal climate. However, the genetic control of these traits is not well understood, and, for example, growth cessation does not appear to be controlled by day length as in many other boreal tree species.

Temperatures Inhibiting Endodormancy Completion in Japanese Pear Flower Buds
The effects of high temperature and subzero temperature on endodormancy completion in flower buds of Japanese pear (Pyrus pyrifolia Nakai cv. ‘Kosui’) were investigated using potted trees. The trees were chilled in temperature-controlled (daily cycles of 6/6°C, 6/−3°C, 6/−6°C, 18/6°C, 21/6°C and 24/6°C) dark rooms from late Octoer or from early ...

Dormancy of 'Imperial Gala' apple and 'Hosui' pear tree buds in a region of low chill occurrence
The objective of this work was to evaluate the dormancy dynamic of Imperial Gala apple tree buds and Hosui pear tree buds in a region of low chill occurrence. Experiments were conducted between April and August in 2007 and 2008.

In the regions with mild winters, usually the chilling requirements for bud dormancy release of grapevines are not fulfilled, and only the highly toxic products CaCN2 (calcium cyanamide) and H2CN2 (hydrogen cyanamide) are recommended in conventional ...

Cultivar and areal differences in the breaking period of bud endodormancy in pear plants
Abstract We investigated the occurrence of bud break in Japanese pear [Pyrus pyrifolia (Burm.f.) Nakai] cultivars and wild pear species to estimate the chilling requirement (CR) for breaking bud endodormancy. The leaf buds of the ‘Hosui’ and ‘Kosui’ cultivars showed a higher CR than their counterpart floral buds.
