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.

Hello to all members of ISHS Working Group Hydroponics & Aquaponics
A group of researchers from the University of Washington on an international project – Cityfood – is running a global aquaponics survey and this survey will provide researchers with real-world information about existing aquaponic systems and farms which define current practices and using results from this survey, researchers aim to connect and empower aquaponic farmers, researchers and decision-makers.

Leonardo Soldatelli Paim is an agronomist, who graduated from the Federal University of Rio Grande do Sul (UFRGS), Porto Alegre, RS, Brazil (2016). After graduation, he started his master’s studies in plant science at the same institution (2017), working through a well-established partnership with the Brazilian Agricultural Research Corporation, Grape and Wine (EMBRAPA) and the State University of Rio Grande do Sul (UERGS).
Ms. Diana Valle is currently a PhD student at the Instituto Nacional de Investigación Agropecuaria (INIA Las Brujas) in Uruguay. For her master’s studies she focused on finding alternative strategies to the chemical control of Cacopsylla bidens, one of the main pests in pear orchards. Following that work in her PhD, she is mapping the trophic networks that involve C. bidens as a prey, because the information is scarce on which of the generalist predators is effectively feeding on C. bidens.
Ms. Violeta Lindo García is a PhD student at the Institute for Food and Agricultural Research and Technology (IRTA) in Lleida (Spain) working in the field of postharvest physiology. The main objective of her thesis is to study the biochemical and physiological basis of superficial scald in different pear cultivars as well as to elucidate some key aspects of pear ripening. Superficial scald is a physiological disorder affecting the peel of both apples and pears after cold storage and leading to important economic losses.
Having grown up around horticulturists – my grandfather Dr. Carl Campbell was a Professor Emeritus of Horticulture (tropical fruit crops) for the University of Florida (UF) – a strong passion for researching and consuming horticultural crops has always been inherent. A three-time UF gator, I received both my bachelor’s and master’s degrees from UF, studying food science with a focus on the sensory sciences.
