Modeling bud development during the quiescent phase in red-osier dogwood (Cornus sericea L.)

The Annual Phenological Cycle

“…3.25c), Kobayashi et al (1982) and Kobayashi and Fuchigami (1983a, b) presented dynamic simulation models for the effects of air temperature on dormancy development and bud burst in Cornus sericea. Using data from a carefully planned set of experiments, they formulated a dynamic simulation model for each phase of dormancy: deepening rest , decreasing rest (Kobayashi and Fuchigami 1983a), and quiescence (Kobayashi and Fuchigami 1983b). In accordance with the feedback principle introduced in Sect.…”

“…This conclusion is unavoidable, for the equations of the four models do not imply meaningful air temperature responses. The model for quiescence (Kobayashi and Fuchigami 1983b), for instance, implies negative values of the rate of development for the entire air temperature range. Contrary to the simulation models developed, however, the empirical results reported in these studies are meaningful and informative.…”

Comparison of two air temperature based models for predicting phenophase occurrence in Persian lilacs (Syringa chinensis) cultivar Red Rothomagensis

“…Although air temperature is an important factor influencing plant development, the effect is not linear in Persian lilac (8) and other woody plants (6). Other environmental factors must be taken into account, as well as the physiological status of the plant.…”

Influence of Winter Protection Covers on Survival and Hardiness of Container Grown Ilex crenata Thunb. ‘Green Island’ and Euonymus fortunei (Turcz.) ‘Emerald 'n Gold’

“…Temperature is a critical factor in the rate and degree to which plants will acclimate and deac climate. Unlike shoots, which are strongly influenced by stage of growth, mature roots acclimate only with lowering temperatures (3,4,6). For shoots, deacclimation can occur with temperatures above 20°C (68°F) when the plant is at its hardiest level and at any temperature above 5°C (41OF) at the quiescence growth phase (end of rest) (3,4,5).…”

Winter protection systems will influence the canopy air and medium temperatures of container grown plants (1,10), thus af fecting this process.…”
