Determining of chilling and heat requirements of olive cultivars growing in Fars Province is important for the selection of cultivars that will exhibit satisfactory growth and development. The purposes of this study were determining the chilling and heat requirements of olive and comparison of Utah and Positive Utah Chill unit (PCU) models for determining the chilling requireme...

Chrysanthemum (Dendranthema grandiflorum cv. Jinba) shoot branching is determined by bud outgrowth during the vegetative growth stage. The degree of axillary bud outgrowth is highly influenced by environmental conditions, such as nutrient availability. Here, we demonstrated that phosphorus (Pi) starvation significantly reduces axillary bud outgrowth in chrysanthemum. A strigolactone (SL) biosyn...

ECOPHYS is a complex computer model that simulates the growth of hybrid poplar and aspen trees. Its primary purposes are to identify major physiologically-based factors that influence tree growth and to predict how interactions among them and with the external environment will affect growth (Isebrands et al., 2000). ECOPHYS' capabilities and submodels of various tree ecosystem processes continu...

dog rose (rosa canina) has been using as a rootstock for ornamental roses also it is one of the medicinal plants. it can be propagated under in vitro conditions. after removing chilling requirement of buds, axillary wood buds of dog rose were cut in three nodal positions (lower, middle and terminal) on the stem and then explants after decontamination, cultured on murashige and skoog medium (ms ...

Meristematic activity in the bud meristem of Abies nordmanniana was visualized by ubiquitin immunohistochemical localization from before bud break and throughout shoot expansion. Ubiquitin was detected in meristematic cells either in the cytosol or nucleus, or both, depending on tissue type and developmental stage. During winter dormancy, ubiquitin was only observed in the protodermal/hypoderma...

Aims: This work aims to evaluate the efficiency of Revent® 500 SC (Thidiazuron) concentrations as a bud breaker promoter in apple trees, cv. Maxi Gala and Supreme Fuji, through phenology, sprouting buds, fruit set production per plant.
 Place Duration Study: The experiments were carried out southern Brazil, municipality Caçador / SC, during seasons from 2017 2019, cultivars Fuji Suprema Ma...
