This study focuses on the processes of developing climate change adaptation strategies by grape growers producing wine. This is part of a geographical approach that considers grape vine cultivation practices, the environment, and the effect on humans. The hypothesis tests the perception that climate change and the representations by stakeholders play an important role in the adaptation process and in the agricultural practices.
The hazelnut (Corylus avellana L., ‘Tonda Gentile delle Langhe’ (TGL)) remains one of the most appreciated nut trees by the food industry. Its production has been expanded world-wide to allow extensive plantations. Still TGL is known to be highly sensitive to climate outside of Piemonte, Italy. Its moisture sensitivity is expressed as a rigid stomata behavior with stomata closing in the early morning at a vapor pressure deficit of the atmosphere (VPD) of 10 hPa.
I graduated with a B.S. in Biology from the Faculdade de Ciências da Universidade do Porto (FCUP), Porto, Portugal, in 2012. I then obtained an M.S. in Biological Aquatic Resources. In 2015, I began an M.S. in Agricultural Engineering studying irrigation in vineyards at the same institution. I am a member of "GreenUPorto – Sustainable Agrifood Production" Research Centre and am currently a PhD student. My goal is to understand how irrigation affects fruit and wine production in the Douro Region, one of the oldest production regions of the world.
During the last several decades, environmental pollution problems caused by the extensive use of chemical herbicides have encouraged the introduction of integrated crop production. A further boost to these methods has been provided by market demand, where organic or “biologique” products are increasingly requested by consumers. In vineyards and orchards, one of the most widely used methods of non-chemical weed control is through the mechanical action of agricultural implements.
Controlled atmosphere or modified atmosphere packaging are clean and potentially effective techniques to extend the storage life of dragon fruit (Hylocereus undatus). Application of these techniques requires thorough knowledge about the fruit respiration rate. To this end, this study aims to model the respiration rate as a function of O2 and CO2 level, and temperature, using Michaelis-Menten kinetics and Arrhenius’ law. Dragon fruit were incubated in closed containers with different initial O2 concentrations (5-21%), initial CO2 concentrations (0-10%), and temperatures (2-35°C).

Zhuping Fan is a candidate for an MS degree at Beijing Forestry University, China. She is studying repeat blooming or remontant flowering of bearded iris (Iris germanica). She is also evaluating Iris through traditional hybridization and molecular breeding methods. Bearded iris appears to have a thick and bushy “beard” on its colorful falls. This flower annually blooms in May in Beijing, China. However, some cultivars bloom twice each year, in May and October. This reblooming enhances the popularity of this flower and adds commercial value to this crop.

Regulation of fruit size is a major economical factor for numerous horticultural crops. Specifically, in apple (Malus × domestica Borkh.), increases in fruit size will result in increased market value. Many factors play a role in determining final fruit size in apple, some of which have been well studied. Besides being responsible for the attachment of fruit to the tree, the pedicel also provides a connection between the fruit and the source of water and nutrients. Therefore, we hypothesized that the pedicel can be a factor that is involved in the regulation of apple fruit size.
Martin Penzel is a PhD candidate in the Working Group of Precision Horticulture of the Leibniz Institute for Agricultural Engineering and Bioeconomy (ATB), Potsdam, Germany. For his doctoral study he is focusing on precision thinning of apples and the gas exchange patterns of pre-harvest fruit and leaves. His goal is to determine the optimum crop load according to the carbon balance of the trees. The effect of mechanical thinning on fruit drop and final fruit number of ‘Elstar’, ‘Gala’ and ‘Pinova’ apples was investigated in 2011 and 2014.
In banana (Musa L.), somatic embryogenesis (SE) is a high throughput technique for mass propagation of quality planting material, genetic transformation and induced mutations. Through SE, a large number of plantlets can be generated from 1 mL settled cell volume of embryogenic cell suspension (ECS). Although SE is well reported in selected banana cultivars, most of the commercial cultivars are recalcitrant to SE. Knowledge of the genes responsible for SE is important to induce SE in recalcitrant cultivars.
Fares Belhassine is a PhD candidate studying alternate bearing of apple trees (Malus × domestica Borkh.), at the French National Institute for Agricultural Research (INRA), in the Architecture and Functioning of Fruit Tree (AFEF) team, Montpellier, France. Fruit trees are prone to alternate bearing and the inhibition of floral induction (FI) under high crop load conditions.
Agriculture has evolved tremendously to increase productivity and quality in the past decades. It was often achieved by plant breeding and at the cost of an increasing dependence on external inputs, i.e., water, fertilizers and pesticides. Apple orchards are no exception. Society is now questioning the means used because of the generated environmental pollution and health issues. Different solutions have been considered to reduce this dependence including redesigning agrosystems to rely on ecosystem-based services.
