Brianna Heilsnis is a Ph.D student in the Department of Horticulture at Oregon State University, Corvallis, Oregon, USA, under the supervision of Dr. Shawn Mehlenbacher in the Hazelnut Breeding and Genetics lab. Her research is focused on host plant resistance to eastern filbert blight (EFB), which is caused by the ascomycete Anisogramma anomala. Currently, the hazelnut industry in Oregon is protected by a dominant allele on linkage group (LG) 6, originally discovered in the European hazelnut, Corylus avellana ‘Gasaway’. However, when tested against other A.
Tree architecture is important because it influences the light interception in the canopy. It determines where the different organs (e.g., leaves and fruits) are borne and, consequently, the source-sink interactions on the tree. Tree architecture directly affects the yield of filbert (Corylus avellana L.).
Felix Büchele is a PhD candidate from the University of Hohenheim, currently conducting research at the Kompetenzzentrum Obstbau Bodensee in Ravensburg, Germany, studying postharvest physiology of horticultural crops. Although long-term cold storage has become an essential part of the production and marketing strategy of apples worldwide, it remains associated with significant risks, as well as high energy usage, and subsequently high costs.
Australian mangoes (Mangifera indica) enjoy a high reputation owing to their large size, attractive skin blush, and sweet and juicy taste. Increasing demand in overseas markets, particularly Asian, indicates a great potential for export. However, risks during export such as high storage temperature in air freight or long in-transit times of sea shipments can cause loss of fruit quality and shelf life, and consequently disappoint consumers.
Clara Gambart is a PhD student at the Laboratory of Tropical Crop Improvement at KU Leuven (the University of Leuven, Belgium) and graduate research fellow at the One CGIAR (formerly the Consultative Group for International Agricultural Research). In 2019, she obtained her Master’s degree in Agricultural Sciences at the Faculty of Bioscience Engineering (KU Leuven). Triggered by her Master thesis, in which she investigated potential agro-ecological intensification strategies on banana-based farming systems, she started a PhD in 2019.
Leaf fall in the evergreen mango (Mangifera indica L.) is affected by physiological age and light environment. Details of these effects need to be determined. Previous studies have not described the dynamics of annual leaf fall of these trees. Our work aimed to decipher the effects of architectural and environmental factors on leaf fall at the scale of the growth unit (GU) during a year. Our experiment began by describing the initial states of 240 GUs, sampled from five mature ‘Cogshall’ mango trees at three depths, expressed as 1, 2, or 4 GU from the terminal GU along the branch.
Maintaining healthy soil is a major challenge in agriculture. Tree-based intercropping is very promising to ensure high production and conserve soil quality, as shown in agroforestry systems. Trees improve soil fertility through the input of organic matter by litterfall and root turnover, which enhance the soil microbial activity. This study aims to evaluate the effects of apple trees (Malus × domestica Borkh. ‘Golden Delicious’) on soil qualities and their potential to improve the yield of an unfertilized organic radish crop (Raphanus sativus L. ‘Ostergruss’).
To determine strategies to increase plant tolerance to high temperature we must examine plant physiological and metabolic processes. High temperature leads to an alteration in photosynthesis, modification of plant metabolism, plant growth reduction, and overall reduction in the quality of horticultural products. Diplotaxis tenuifolia L., commonly known as wild rocket, is a member of the mustard family, Brassicaceae. This plant is cultivated as a baby-leaf salad. Our goal in this study was to understand the physiological and molecular responses in this plant when subjected to heat stress.

The poor quality of organic seeds due to pathogen contamination is a main challenge for the development of organic farming. In conventional agriculture, chemical seed treatments can effectively manage this issue. In organic agriculture, however, only limited seed treatments are available. The goal of our project was to evaluate seed treatments compatible with organic farming against two bean diseases, anthracnose caused by the fungi Colletotrichum lindemuthianum and halo-blight caused by the bacteria Pseudomonas savastanoi pv. phaseolicola.

Date palm (Phoenix dactylifera L.) is a widely cultivated agricultural crop in most Arab countries. ‘Barhi’ is very popular among the date palm cultivars grown in the United Arab Emirates and is often consumed at the Bisr stage (crunchy apple-like texture fruit). After harvest and during marketing, the major challenge of this fruit (Bisr stage) is to retain its long-term quality. Several studies have reported different spray treatments with elicitors or edible coating to improve the marketability of fresh fruit.
Date palm (Phoenix dactylifera L.) is one of the most important fruit trees grown in arid and semi-arid regions. Despite the immense capabilities of date palm, maintaining the fruit’s quality, marketability, and shelf life remains a challenge. Chemical treatments control some diseases but they can be harmful for the environment. Our goal was to find a safe, natural, effective, economical disease treatment.

Over the past decade, South Africa has seen an increase in the plantings of Protea cynaroides as an export cut flower. Producers rely on superior cultivars, such as P. cynaroides (L.) ‘Arctic Ice’, to secure the desired returns. The production volumes of ‘Arctic Ice’ have more than tripled over the past three years. Current cropping distribution for ‘Arctic Ice’ is restricted to two peak periods in the southern hemisphere; April-May and October-November, with low productivity outside these main harvesting seasons.
Paz E. Zuñiga is a candidate for Dr.Sc. in Plant Biology and Biotechnology in the Laboratory of Plant Molecular Physiology (LFMV) of the Institute of Biological Sciences at the University of Talca, Chile, under the supervision of Prof. Dr. Carlos R. Figueroa. They are currently interested in studying the transcriptional regulation of anthocyanin biosynthesis on strawberry (Fragaria × ananassa) fruit. Strawberries are a great source of flavonoids, such as anthocyanins, which can protect plants against stress due to their antioxidant properties.
Tomatoes are a popular horticultural commodity prone to quick postharvest deterioration. In the absence of cold storage and postharvest fungicides to prevent spoilage, other means to preserve the shelf life of fresh tomatoes is sought. Reducing decay and extending the shelf life of such a popular and easily accessible food crop will decrease food waste.
Sulphur (S) is a widely used plant protection agent (mainly against apple scab) in organic apple production in temperate regions. Current attempts of reducing the use of copper (Cu) to avoid heavy metal accumulation in the soil lead to an increased application of S. In Germany, the amounts of S range from 30 to 90 kg ha-1 year-1 in intensive, organic apple production systems.
Vegetables require high amounts of nitrogen (N) and rather low amounts of phosphorus (P). Therefore, fertilization with farmyard manure often results in nutrient imbalances, commonly seen in P oversupply. Leguminous green manures increase the nutrient supply of the successive vegetable crop by the mineralization of residues and the exclusive N input into the soil by biological N2 fixation. This may reduce the need for organic fertilizers in vegetable production and contribute to more balanced nutrient flows.

Increasingly, people want to enjoy the advantages of living in a city with the many cultural offerings and recreational opportunities. In addition, work tends to be close to home, and stores and other activities also remain within a short distance. To enjoy these benefits, people have up until now accepted living in a tiny area. Their houses have been small flats, without a garden, park, or forest nearby for relaxation or exercise. In addition, city dwellers exist in a highly populated environment and need infrastructure, including reasonable living space and transport.
Chian-Chi Lin is an undergraduate student of the Department of Medical Laboratory Science and Biotechnology, Asia University, Wufeng, Taichung, Taiwan. Her research is addressed to identify a new virus affecting amaryllis (Hippeastrum hybridum Hort.), which is a perennial bulbous plant belonging to the Amaryllidaceae family very popular as garden flower in Taiwan. The ornamental value of amaryllis plants can be greatly affected by several viruses.
My PhD research work focuses on changes in grape (Vitis vinifera) berries upon fungal infection. Many fungi, such as Botrytis cinerea, Erysiphe necator, and Esca complex trunk disease, cause major economic damage for the viticulture economy and wine production industries. Different species of pathogens utilize diverse approaches for infection, leading to specific alterations in the affected host. In addition, diverse cultivars have different levels of susceptibility to these pathogens.
