Many temperate and boreal tree species have a chilling requirement, that is, they need to experience cold temperatures during fall and winter to burst bud normally in the spring. Results from trials with 11 Pacific Northwest tree species are consistent

Chilling Requirement of Pecan [PDF]
`Dodd' pecan seedlings [Carya illinoinensis (Wangenh.) K. Koch] were chilled at 6C for 0 to 1800 hours in 300-hour intervals and percent budbreak and days to budbreak recorded. Chilling duration required for ≥ 50% budbreak was 900 hours.

Preserving Minors’ Rights After Casey: The “New Battlefield” of Negligence and Strict Liability Statutes [PDF]
Simultaneous Switching Noise (SSN) is one of the major problems in today highspeed circuits. Power-Ground voltage fluctuation is significantly increasing due to L ∗ (di/dt)) noise known as Power-Ground bounce and can be one major noise source in modern ...

POLLEN DEVELOPMENT AND CHILLING REQUIREMENTS IN APRICOT CULTIVARS [PDF]
Apricot (Prunus armeniaca L.) flowers at the end of the winter but flower bud differentiation occurs the previous summer. During the winter, the flower bud enters dormancy and resumes growth prior to flowering. The time the flower bud remains dormant is genetically and also environmentally controlled and is a major factor in determining the adaptation ...

Determination of Chilling and Heat Requirement of Four Apricot Cultivars of Khorasan Razavi Province
Introduction:Dormancy is one of the most important stages in the life cycle of temperate plants and plants are required to exit from it with supply of chill unit. Flowering is defined with chilling and heat requirement. Owing to low chilling requirement,

CHILLING REQUIREMENTS OF HAZELNUT CULTIVARS [PDF]
Chilling requirements of 44 genotypes of Corylus avellana L. were estimated by cutting shoots in the field at weekly intervals and forcing them in a warm greenhouse for four weeks. The chilling requirements of catkins, female flowers, and leaf buds were assumed to have been met when development occurred on more than half of the respective plant parts ...

Chilling requirement for seed germination and phenological observations on peach cultivars
In subtropical climate areas, the models and methods proposed to evaluate the chilling requirement of temperate fruit crops often do not provide satisfactory results, thus calling for the development of alternative techniques.

ACC Synthase Genes Related to Cold-dependent Ripening in Pear Fruit [PDF]
The differential regulation of ACC synthase genes has been studied in pear cultivars that either require a long chilling treatment before they are capable of ripening (‘Passe-Crassane’, PC) or not (‘Old-Home’, OH) and in OH x PC hybrids having no (A16)
