Effect of chilling, hydrogen cyanamide, hot water and bud scale removal on bud break of 'Tifblue' rabbiteye blueberry
… deciduous fruit trees have poor and delayed bud break when they are grown in warm areas. The delay is due to a lack of the chilling which is required to break bud endodormancy. Bud endodormancy can be overcome in some species by treatments such as H<sub>2</sub>CN<sub>2</sub>, heat, and bud …

Quantitative Trait Loci Analysis of Low Temperature Responses in Grapevine F2 Population
… growth cessation, acclimation, deacclimation and bud break. Developing an understanding of the genetics behind the complex trait requires connecting the phenotype with the genotype to enable discovering the underlying genes that can contribute to quantifiable differences between individuals. The …

Bud-forcing and in vitro culture for conservation of oak (Quercus L.)
… were conducted to determine 1) the viability of bud-forcing Quercus and effectiveness of 6-benzylaminopurine (BAP), a cytokinin, on stimulating bud break and shoot elongation of Quercus and 2) the responses of species from the three North American Quercus sections (Lobatae, Quercus, and …

Eastern Hemlock Needle Physiology as Impacted by Hemlock Wooly Adelgid and Treatment with Imidacloprid
… Inc, Lincoln NE). Chlorophyll fluorescence and bud break were also characterized for all trees at two of the three sites. After one complete growing season, we found a slight increase in photosynthetic rates (4.98 %), increased bud break at Fishburn (562 %) and Mountain Lake (25.6 %) sites, and …

PREDICTING POTENTIAL ASCOSPORE DOSE OF VENTURIA INAEQUALIS (CKE) WINT IN COMMERCIAL APPLE ORCHARDS OF NEW HAMPSHIRE (MODELING, EPIDEMIOLOGY, DISEASE MANAGEMENT)
… of the orchard floor covered by leaf litter at bud break, and ascospores per ascus. Disease incidence and the proportion of lesions that formed mature ascocarps were strongly correlated; lesion fertility was directly proportional to disease incidence at leaf fall. Most lesions from commercial …

Nitrogen Fertilization of Hybrid Hazelnuts in the Upper Midwest of the USA
… and mid-September 2005. N uptake was slow before bud-break. N applied in the spring after bud-break was quickly translocated to plant parts with the greatest near-term demand for N: first to leaves, then to nuts and catkins. Nitrogen applied in August and September appeared in new shoots the …

Seasonal and site relationships to acetylene reduction by actinorhizal black alder and Russian olive root nodules
… olive. Alder ARA began about 2 weeks after bud break. Initiation of Russian olive ARA coincided with bud break. Alder ARA midday rates of 15 to 20 umoles C$\sb2$H$\sb4$/ (gram dry nodule$\cdot$hour) occurred for about 150 days. The length of the Russian olive ARA season was similar, but the …

Population Dynamics of Ice Nucleation Active Bacteria on Prunus Persica Cultivars
… a ten week period with maximum populations at bud break followed by a gradual decline. A new INA species, Serratia liquifaciens was identified. The INA species were isolated in the following proportions: P. fluorescens 42%, P. syringae 24%, E. herbicola 19%, and S. liquifaciens 15%. Peach …

Growth of Japanese holly as affected by nitrogen and growth regulators
… were studied. Nitrogen applications promoted bud break after rooting of summer cuttings and also enhanced the growth of winter rooted cuttings. Generally, plants grown at 300 and 150 ppm N had greater initial shoot numbers and length, secondary shoot numbers and length, height, width, fresh …

Performance of selected different types of stone fruits in a summer rainfall area, South Africa
… are described in general as the absence of bud break, delayed foliation, reduced fruit set as well as reduced fruit quality. Therefore, after bud break, fruit trees show insufficient symptoms such as paralysis of the shoot growth, development of small leaves, low rate of effective …

Basis for Selectivity of Isoxaben in Ajuga (Ajuga reptans), Wintercreeper (Euonymus fortunie), and Dwarf Burning Bush (Euonymus alatus 'Compacta')
… that isoxaben applications made one month after bud-break caused 30 to 45% injury to dwarf burning bush. However, the plants outgrew the injury in the following year. Dwarf burning bush was not injured from applications of isoxaben made at the dormant stage or two months after the bud-break …

The Role of Urban Climate and Land Cover in Phenology, Nest Success, and Habitat Use
… in the warmer sites and at sites with earlier bud break by Populus spp. Peaks in foliar invertebrate abundance were also weakly associated with leaf out, while the sequence of peaks by aerial invertebrates was related more to the level of urbanization at a site. The results from these studies …

Relationship of free radical scavenging enzymes to fruit growth, development, ripening, and senescence in 'Red Delicious' apples
… investigated during different stages of fruit bud growth and development in 'Red Spur Delicious' apples (Molus domestica Borkh.). Changes in the activities of these enzymes were also monitored at harvest and during cold storage in relation to ripening, senescence, and scald development. At bud …

Unraveling Molecular Mechanisms Regulating Dormancy and Bloom Time in Apple (Malus × domestica Borkh)
Bud dormancy is an essential characteristic of deciduous woody perennials, including apple, to cope with the low temperatures during winter. The release from dormancy and subsequent budburst in apple can only occur after fulfillment of chilling and heat requirements. In the Mid-Atlantic region, …

Characterization of water stress during cold storage and establishment for Acer platanoides and Crataegus phaenopyrum
… storage for treatments exposing roots. Days to bud break for Acer and Crataegus seedlings decreased with increased storage time for the whole plant covered treatments but increased for both species when stored with exposed roots. Maple marketability, percent of trees with ≤ 10% shoot dieback, …
