Small RNA (sRNA) sequences are precisely 21, 22 and 24 nt (nucleotide) in length. Deep sequencing of sRNAs generates sRNA datasets. This procedure allows for the discovery of novel viruses and the identification of viral genomes for use in reference databases. RNA samples from Rubus and Ribes germplasm in Finland were combined for a large-scale virus diagnosis. The collection included ten red raspberry (Rubus idaeus L.) mother plants and one accession each from blackcurrant (Ribes nigrum L.) and redcurrant (Ribes rubrum L.) cultivars.
Growers and scientists alike within the field of horticulture are continually seeking ways to improve sustainable production of food crops. The application of plastic mulches is one way to enhance crop production through improved weed management and modification of soil temperature and moisture. However, the use of plastics in society is under scrutiny and end-of-life management of agricultural plastics is a growing concern that threatens sustainability. Biodegradable plastics are an alternative to non-degradable polyethylene and polypropylene plastic mulches.

Impact of Covid-19 on the ISHS symposia
We understand that this is a time of concern. The International Society for Horticultural Science (ISHS) is taking all developments concerning the coronavirus (Covid-19) seriously and will continue to closely monitor and adequately respond to this unprecedented situation.
The ISHS Secretariat is working in close cooperation with the respective conveners of ISHS symposia and regional congresses who have been forced to suspend meetings because of the coronavirus issue, to find the best possible alternative.

The title Principles of Modern Fruit Science marks the epitome of the tremendous advancements made over the years in understanding the fundamentals of plant sciences such as physiology, molecular biology, breeding, climatology, soil science and their integration into the comprehensive practice of profitable fruit production.
Dr. Sansavini and his colleagues are presenting a comprehensive textbook that covers each aspect of modern fruit growing and illustrates the evolution of complex fruit cultural systems over time.
Scripta Horticulturae #20: Global Kiwifruit Industrial Development Conference has been published.

All terrestrial plants transpire water, but where exactly does that water come from within the soil? This seemingly simple research question has been the subject of studies for many years. Stable isotopes of oxygen and hydrogen “tracers” have proven useful for shedding light on patterns of plant water use. However, the use of such tracers alone limits our understanding of patterns of source uptake and the mechanisms behind tracer observations. To go beyond this black box approach, we integrated measurements of stable isotope composition in xylem and soil water.
Variations of tomato fruit weight and composition throughout the cycle of production make the management of fruit yield and quality complex. These variations are linked to the fluctuation of water and carbon available for fruit growth and depend on the genotype and environmental conditions. Some structural functional plant models can predict the concentration of water and carbon in the plant architecture and the consequences on fruit growth. Obtaining measures of sap fluxes in situ is difficult.
Gianmarco Bortolotti is a PhD student at the Department of Agricultural and Food Sciences of the University of Bologna, Italy. He participated in the International Symposium on Precision Management of Orchards and Vineyards, presenting innovative system integration of fruit trees and energy co-production. The study determined that more than 50% of the hail-net surface of an orchard can be covered by organic photovoltaic (OPV) films without decreasing plant performance. This was the initial concept of his research within the ecophysiology group led by Professor Luca Corelli Grappadelli.

(CIATEJ), Mexico, where she collaborates on the project 258866 supported by SEP CONACYT CB-2015-01 for the genetic improvement and flowering in Polianthes, under the supervision of Dr. Ernesto Tapia. Tuberose (Polianthes tuberosa) is the most well-known species of the genus.
Isabel Niebla López is a Master’s Degree student in Floriculture Sciences at the Research Center for Assistance in Technology and Design of Jalisco State, A.C. (CIATEJ), Mexico. Currently, her research evaluates different forcing temperature treatments to control the flowering time of Polianthes tuberosa. It is supported by SEP CONACYT CB-2015-01 project number 258866. The production of tuberose as a cut flower has great economic importance worldwide and it is carried out both in greenhouses and in open fields.
Tian Gong is a PhD student in the Horticultural Sciences Department at the University of Florida, USA. She completed her B.S. and M.S. at Fujian Agricultural and Forestry University in 2015. Her dissertation research project is focused on categorizing tomato rootstock and scion interactions. The rootstock impacts on tomato scion's vegetative growth and reproductive development, especially fruit yield and quality, can be complex. A detailed understanding of rootstock-scion synergy and underlying mechanisms is needed to optimize the overall performance of grafted tomato plants.

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).
Claire Scofield is currently pursuing a Master of Science at Massey University, Palmerston North, while working as a Research Associate at The New Zealand Institute for Plant and Food Research Limited, Clyde Research Centre, New Zealand. Her work has a strong focus on pre-harvest and postharvest physiology of stone fruit, particularly cherry and apricot. Her research entitled “Light interception and yield of sweet cherry and apricot trees grown as a planar cordon orchard system design” was presented at the IHC2018 in Istanbul, Turkey.
