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.

Nature, plants, or gardening activities have a positive impact on people’s well-being, mental and physical health.
Exposure to nature has been proven not only to restore our attention and increase positive emotion but also to lower stress and anxiety levels, bringing multiple health effects. Neurological research has found that a 90-minute walk in nature lowers the activation of emotion regulation areas in the brain, which is associated with a lower risk of mental illness. While the positive health benefits of human interaction with nature have been described, our knowledge is limited on the key feature or elements in nature that are critical to our health.
In Mexico, ‘quelites’ are consumed tender plants that grow adjacent to other crops. The consumption of quelites, as vegetables, in Mexico has occurred since pre-Hispanic times. Nowadays, among the most cultivated, studied, and consumed species are huazontle (Chenopodium berlandieri subsp. nuttaliie), quelite (Chenopodium berlandieri), verdolaga (Portulaca oleracea), and chaya (Cnidoscolus acnitifolius); however, many others with nutritional and functional potential have not been studied.
Itzel Rojas Puebla is a doctoral student in the Faculty of Agricultural Sciences at Autonomous University of the State of Mexico. Her research focused on evaluating bacterial strains from different pathotypes and origins to develop biofilm using the epidermis of tomato fruit (Solanum lycopersicum L.) as a substrate.

Fresh fruit and vegetables are sensitive products with a short shelf-life. Often these are packaged to maintain their quality for a longer time. Active substances can be added in packaging to provide additional benefits such as moisture absorption, antimicrobial effect or removal of foul odours. Among such active substances, some materials scavenge or remove ethylene. Ethylene is a colorless gas, often referred to as “ripening hormone,” produced by fruit and vegetables. Accumulation of ethylene in packages causes the undesireable fast ripening in fruit and vegetables.

The modern consumer has become accustomed to a year-round supply of apple fruit. This continuous availability is possible through long-term storage techniques. Growers are able to extend fruit quality by controlling the immediate atmosphere around the apple, combining a low oxygen and high carbon dioxide gas mixture with low temperatures. This form of long-term storage is referred to as controlled atmosphere (CA) storage. In some cases, the storage conditions are too severe for the fruit and result in storage disorders.
