Shifts in suitability distribution of deciduous and citrus fruit trees under climate change in South Africa: a large-scale empirical study
South Africa is the largest fresh fruit exporter by volume in the Southern Hemisphere. The quality and quantity of fruit produced depend on local climate, soil quality, water quality and availability. Climate change impacts may undermine the potential contributions of important fruit crops toward …

Adoption Potential of two Agroforestry Technologies: Improved Fallows and Domestication of Indigenous Fruit Trees in the Humid Forest and Savannah Zones of Cameroon
… vegetative propagation of a number of indigenous fruit trees in farmer nurseries. However, wide-scale adoption of vegetative propagation is likely to be constrained by the cost of nursery infrastructure and materials. Measures to enhance adoption potential would thus include reducing nursery …

Performance of selected different types of stone fruits in a summer rainfall area, South Africa
Temperate fruit trees cultivated in areas of mild winter conditions result in a number of insufficient chilling symptoms. Such insufficient symptoms are described in general as the absence of bud break, delayed foliation, reduced fruit set as well as reduced fruit quality. Therefore, after bud …

ΔΙΕΡΕΥΝΗΣΗ ΜΕ ΒΙΟΧΗΜΙΚΕΣ ΜΕΘΟΔΟΥΣ ΤΟΥ ΜΗΧΑΝΙΣΜΟΥ ΤΟΥ ΑΣΥΜΒΙΒΑΣΤΟΥ ΣΤΑ ΟΠΩΡΟΦΟΡΑ ΔΕΝΔΡΑ
… SELF INCOMPATIBILITY IN THE REPRODUCTION OF THE FRUIT TREES ALMOND AND SWEET CHERRY WAS INVESTIGATED FROM ITS BIOCHEMICAL ASPECT, AS A FORM OF CELLULAR RECOGNITION BETWEEN POLLEN AND PISTIL. REGARDING THE MORPHOLOGY OF INCOMPATIBILITY IT WAS CONFIRMED THAT IN THE TWO SPECIES IS OF THE …

Análise faunística e flutuação populacional de moscas-das-frutas (Diptera: tephritidae) .
The Brazil is the third largest producer of fruits in the world rankings, with 43 million tons produced, ago only China and India. But the export activity is still low, mainly due to the low level of technology used today in the cultivation of fruit trees. The fruit-flies are pests of greatest …

Pão em árvores: um estudo do caso sobre a fruta-pão Artocarpus sp no Brejo Paraibano
The breadfruit (Artocarpus sp) is a plant belonging to the family Moraceae, tropical and Asian. Plant widely cultivated in the imperial period in Brazil, however today this crop is scarce, where this crop is now planted in backyards of homes and crops of small rural farmers. The field research was …

Navigating in a Rainforest: Movement Patterns in a Neotropical Primate. The Black Howler Monkey
… Mexico, where I marked all individual feeding trees (N = 931 trees) from the top ten preferred tree species. My findings first showed that black howlers navigated through routes more frequently than simulated random-walker agents. Second, frequently used routes were associated with potential …

Plant virus detection and diversity in a mixed tree fruit orchard determined through metagenomic-based analysis of honeybee (Apis mellifera) collected samples
… production, especially in long-lived fruit orchards where profitability of individual plants can take years to achieve. Over time, fruit trees can accumulate various viruses, leading to complex mixed infections. Furthermore, emerging viruses can create epidemics causing significant …

The genetic determinants of vigour control and precocity by pear (Pyrus communis L.) rootstocks
The growth habits of fruit trees have a significant influence on their efficiency in commercial production. Small tree stature allows high-density plantings and therefore more efficient land use, while minimising the length of the trees’ juvenile period means the orchard becomes profitable sooner. …

Economic Tools to Improve Forest Practices' Outcomes
… findings reveal that tree planting, except for fruit trees, compared to agricultural crops, diminishes the household's probability of facing losses due to climate change, extreme weather events and pest attacks. Specifically, there is a 14.4% reduction in the probability of facing a loss when …

Effect of chilling, hydrogen cyanamide, hot water and bud scale removal on bud break of 'Tifblue' rabbiteye blueberry
Temperate 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 …

GENOMIC TOOLS TO IMPROVE PEACH (P. PERSICA L. BATSCH) RESILIENCE TO CLIMATE CHALLENGES
As one of the earliest flowering fruit trees, peach is constitutively subjected to yield loss caused by freezing temperature occurrence at blooming time. However, higher winter average temperatures recorded in recent years may lead to anticipated budbreak increasing the magnitude of this …
