Indigenous biocontrol agents such as <em>Streptomyceslydicus</em>, <em>Streptomyces griseus</em> and <em>Streptomyces sannanensis</em> belonging to actinomycetes group, Pseudomonas fluorescens (bacterial) and <em>Trichoderma atroviride</em> (fungal) were selected for the biological control of rhizome rot of turmeric. The results indicated a significantly stronger reduction in disease severity in trial plots treated with <em>Bacillus subtilis</em> based commercial fungicide ‘Companion’ when compared to plants treated with indigenous biocontrol agents. However, it was reverse in trial plots in terms of turmeric rhizome yield potential, yield attributes, physiological components, biochemical constituents and quality characteristics of rhizomes. Among 17 treatments, a dual mixture of <em>S. griseus</em> and <em>T. atroviride</em> achieved the best disease control as well as plant growth improvement when compared to single and triple combinations of biocontrol agents. The present study confirms that exploration of microbial formulations containing <em>Streptomyces</em> soil inoculant to turmeric plants exhibited some benefits to turmeric plant growth as well as controlling rhizome rot disease, which ultimately enhance the overall quality characteristics of rhizomes. Further, our results suggest that a dual combination of biocontrol agents represent a promising method for effective management of rhizome rot of turmeric.</p> 2020-11-23T17:31:06+01:00 Copyright (c) 2020 The Author(s) Morphometric and phytochemical characterization and elevation effect on yield of three potato landraces of the Ligurian Apennines (Northern Italy) 2020-11-23T18:26:28+01:00 Luca Giupponi Valeria Leoni Davide Pedrali Giulia Ceciliani Angela Bassoli Gigliola Borgonovo <p>The great adaptability, productivity and importance in human diet conditioned the diffusion of potato (<em>Solanum tuberosum </em>L.) in very different areas, leading to the formation of numerous landraces through anthropic or natural selection. Genoa mountainous inland is an historical area for potato cultivation and landraces are preserved by farmers associations as “Consorzio della Quarantina”. The aim of this study was the phytochemical and morphometric characterization of three potato landraces of the consortium (Quarantina Bianca, Quarantina Prugnona and Rubra spes) analysing the bio-agronomical performance at different elevations. The commercial cultivar Kennebec was used as control. For the morphometric analysis, the results of pairwise MANOVA shows that only Quarantina Bianca does not present significant differences with Kennebec in the mean shape. The four potato varieties resulted significantly different for the most of the considered phytochemical aspects (among content in ash, starch, solanine, total flavonoids, total phenols, chlorogenic acid, caffeic acid, ferulic acid and radical scavenging activity only starch and solanine content didn’t result statistically different). A remarkable result was a more consistent yield for all the varieties with the increase of elevation in the agronomical trials. We can conclude that Genovese landraces are a good choice to exploit Genovese mountain marginal territories.</p> 2020-11-23T17:29:33+01:00 Copyright (c) 2020 The Author(s) Sugar content and organic acid profiles of local apple cultivars recovered from mountain zones 2020-11-23T18:20:32+01:00 Lourdes Castel Ana Pina Patricia Irisarri Pilar Errea <p>Ancient apple cultivars grown in local areas have so far been largely unexplored and may attract a large share of consumers oriented towards natural foods evoking ancient flavors. In this work, 34 traditional apple cultivars of the Pyrenees were analyzed in terms of sugar and acidity profile and their relation, as alternative fruits for a growing demand in society regarding quality and nutritional proper-ties. The results show a wide range between cultivars of analyzed variables, especially in terms of acid, pH and soluble solids, with high standard deviation values. The results were higher than in other similar studies of commercial apple cultivars, as well as higher values related to other local accessions. The large differences between cultivars can be attributed to the origin of the plant material, since all cultivars were grown under the same geographical conditions and with the same applied agronomic practices. The associations found in this study provide information about the nutritional content of the analyzed apples and their organoleptic and physicochemical qualities, and could be useful in targeting specific consumer requirements. In conclusion, this study highlights the suitability of these local accessions recovered in the Pyrenees as key genetic resources to be used in future breeding programs, as well as its potential use for different products which would open the door to new varieties and new consumption alternatives.</p> 2020-11-23T16:52:06+01:00 Copyright (c) 2020 The Author(s) Evaluating the practicability of commercial food-scanners for non-destructive quality assessment of tomato fruit 2020-11-23T18:18:15+01:00 Simon Goisser Michael Fernandes Sabine Wittmann Christian Ulrichs Heike Mempel <p>The assessment&nbsp; of&nbsp; tomato&nbsp; fruit&nbsp; quality&nbsp; depends&nbsp; on&nbsp; a&nbsp; variety&nbsp; of&nbsp; extrinsic and intrinsic quality parameters such as color, firmness and sugar content. Conventional measurement methods of these quality parameters&nbsp; are&nbsp; time&nbsp; consuming,&nbsp; require&nbsp; various&nbsp; measurement&nbsp; de-vices,&nbsp; and&nbsp; in&nbsp; case&nbsp; of&nbsp; intrinsic&nbsp; quality,&nbsp; involve&nbsp; destructive&nbsp; measurements. Latest research focused on the non-destructive determination of these parameters by using spectroscopic measurements. The goal of&nbsp; this&nbsp; study&nbsp; was&nbsp; to&nbsp; evaluate&nbsp; the&nbsp; capability&nbsp; of&nbsp; three&nbsp; commercially&nbsp; available&nbsp; portable&nbsp; and&nbsp; miniaturized&nbsp; VIS /NIR spectrometers, so called food-scanners, in predicting various tomato quality attributes in a non-destructive way. Additionally, this study evaluated the software provided by manufacturers for building of prediction models by comparing the results derived from those software tools to state-of-the-art software for multivariate analysis. Evaluation of food-scanner spectra resulted in prediction models of high accuracy (r² &gt; 0.90) for tomato fruit firmness, dry matter, total soluble solids and color values L*, a* and h°. Prediction models computed with manufacturer’s soft-ware showed similar accuracy to those derived from state-of-the-art evaluation software. Results of this study illustrate the great potential of&nbsp; commercial&nbsp; food-scanners&nbsp; for&nbsp; non-destructive&nbsp; quality&nbsp; measurement.&nbsp; Further&nbsp; important&nbsp; features&nbsp; of&nbsp; food-scanners&nbsp; with&nbsp; respect&nbsp; to&nbsp; the application along the fresh produce supply chain are addressed.</p> 2020-11-23T16:46:49+01:00 Copyright (c) 2020 The Author(s) Book Review: Strawberries (2nd Edition) 2020-11-21T10:27:48+01:00 Hartwig Schulz <p>This new and updated edition provides a broad, balanced review of the scientific knowledge of strawberries and their cultivation. The worldwide strawberry industry has grown substantially since the first edition was published 20 years ago. Furthermore, methods of cultivation have undergone extensive modifications. Important changes have been made to the taxonomy of strawberries and there is a much better understanding today of how its ancestors evolved. New disease and pest control methods have been developed and a large amount of genomic information has been generated. This information has greatly broadened our knowledge of how flowering and fruiting is regulated and will revolutionize the breeding of strawberries.</p> <p>This book covers various important aspects from taxonomy, ecology, morphology and genetics to environmental physiology, disease and pest control, fruit ripening, storage and processing.&nbsp;</p> <p>Drawing on extensive research and practical experience, the author provides in 8 chapters a thorough review of the evolution of strawberries (chapter 1) and the history of strawberry cultivation (chapter 3). Chapter 3 and 4 summarize the major cultivation systems employed across the world and describe the physiology behind these practices. <br>Chapter 5 addresses strawberry anatomy and developmental physiology including temperature and photoperiod control of flowering. Chapter 6 highlights research work on the fruiting and postharvest physiology. Chapter 7 deals with the diseases and pests of strawberry and describes the individual consequences that came up with the abandonment of methyl bromide.</p> <p>The last chapter reviews strawberry breeding and genetic research, an area where tremendous progress continues to be made. Particularly in Mediterranean and other sub-tropical environments breeding activities increased dramatically over the last two decades. It is reported that strawberry breeders have begun to widely use molecular approaches in their programs including also marker-assisted and genomic selection.</p> <p>This book provides an excellent, concise overview of strawberries and their cultivation and can be therefore recommended without any reservation as an exciting and instructive information to a broad range of readers. Not only does it provide valuable support to students of horticulture and various professional groups such as plant breeders, strawberry farmers, plant physiologists, food technologists and chemists, but it also provides an excellent opportunity for interested laypeople to obtain comprehensive information on the current state of knowledge of strawberry science and cultivation. A number of scientific articles are listed in each annex of the 8 chapters, allowing readers to obtain more detailed information on the individual topics.</p> <p>Bibliography:</p> <p>James F.
