Dormancy and time of bud burst in the sultana vine
Australian Journal of Agricultural Research, 1966Time of bud burst for sultana vines at Merbein has been closely related to sums of daily temperatures at four periods during bud dormancy by a multiple regression covering 17 years, the result being supported by field trials of vine heating. Bud burst is delayed by higher daily maximum temperatures in May.

Tree Physiology
Abstract Early snowmelt is known to accelerate budburst. Budburst and leaf expansion require water absorption, and current-year vessels, which function as water pathways, begin to mature in early spring. However, whether the limitation of xylem reactivation by snow affects budburst and leaf expansion remains unclear.

Temperature Effects on Bud-Burst and Leaf-Fall in Subalpine Larch
Journal of Sustainable Forestry, 1993Phenology was monitored in natural stands of subalpine larch (Larix lyallii Parl.) in parts of four decades. Bud-burst date varied by about six weeks from year to year, and leaf-fall date by a month, suggesting that the importance of photoperiod in these processes has been over emphasized, even in the case of leaf-fall.

Evaluation of temperature models for predicting bud burst in Norway spruce
Canadian Journal of Forest Research, 1999Spring bud development was assessed on cuttings of 17 Norway spruce (Picea abies (L.) Karst.) clones for up to 7 years at two sites in southern and central Sweden. The ability of various temperature models to predict bud-burst timing was analysed. All temperature-based models resulted in significantly better predictions than the null model, day number.

Respiration and oxygen status during bud burst of grapevine
2013Bud dormancy is an important strategy in the phenology of temperate perennial trees, including important crops such as grapevine. Temperature and photoperiod play key roles in regulating dormancy, particularly accumulation of chilling hours. However, dormancy is a quantitative state and in many cases facultative.

Improvement of chilling and forcing model to predict bud-burst
2006Timing of bud-burst for crop and forest species mainly depends on air temperature variation during the winter season. Exposure to a particular duration of cold temperature is needed to meet the chill requirement and break dormancy. The effectiveness of time-temperature combinations on meeting chilling requirements varies between species.
