Download or read book Strawberry written by Toshiki Asao and published by BoD – Books on Demand. This book was released on 2019-10-02 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book mainly deals with pre- and postharvest management practices of the strawberry to ensure that high-quality fruits are delivered to the consumer. The influence of climatic variables, cultural practices, harvesting techniques, and use of chemicals and other natural compounds on fruit quality are discussed. Factors affecting fruit growth and development and processes regarding maturation and biochemical changes during fruit ripening are also presented in one of the chapters of this book. Some chapters provide information regarding harvesting, storing, packaging, transporting, and also selling that affect strawberry quality greatly. Enhancement of yield and antioxidant contents in the strawberry by various natural products, including chitosan and probiotic bacterial, are also included in this book. The final chapter states that antioxidants present in strawberry fruit play a dietary role in alleviating oxidative stress in experimental liver models. This book focuses on the postharvest quality management of the strawberry and provides a useful resource to educationists, traders, and commercial strawberry growers.
Download or read book Plant and Substrate Based Factors Affecting Design and Management of In field Soilless Strawberry Production Systems written by Jose Antonio Gonzalez Fuentes and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The strawberry industry in California has expressed interest in soilless field production as an alternative to soil fumigation, so this research was undertaken to study the response of `Albion' strawberry plants to plant- and substrate-based factors that affect the design and management of such systems.Low substrate aeration reduced shoot and root dry weight, as well as leaf area, stomatal conductance, photosynthesis, plant water potential, and leaf nitrogen concentration. Root growth was greatest at air-filled porosity values between 13% and 25%. With proper irrigation management, strawberries grown at average air-filled porosities between 10% and 25% should achieve high productivity. Root-zone volumes of soilless substrate as low as 2 liters per plant and once-daily irrigation (twice-daily irrigation of mature plants during high-ET conditions) can be used for field production of strawberries without affecting yield, as long as the substrate provides adequate air-filled porosity and available water. Daily plant water uptake peaked in summer at about 0.5 to 0.7 L, and maximum daily nitrogen uptake per plant was 28.5 mg. Nitrogen supplied in a liquid feed at a concentration of 60 ppm is sufficient to support high yields. Large root zone temperature fluctuations negatively affected strawberry plant growth, water relations, fruit yield and quality. We attribute this reduced growth to the very negative stem water potentials that occurred when root zone temperatures were near 5oC. Root zone temperature had little or no effect on photosynthesis, gas exchange, fluorescence, or foliar nutrient levels. The consequences of diurnal RZT fluctuations during strawberry production appear to be small if the minimum temperature is above 7oC. Clonal integration (the capability of reciprocal resource translocation among interconnected plants through their shared stolon) alleviated salinity stress by allowing for resource transfer between interconnected mother and daughter plants. Leaf area, shoot and root dry biomass, gas exchange parameters and instantaneous water use efficiency in salinity-challenged plants were maintained near the values for non-stressed plants. Interclonal resource translocation was mainly driven by the contrast in stress intensity between mother and daughter plants. The results from these experiments are applicable to specification of appropriate conditions for soilless field production of strawberry. Aeration, water-holding and nitrogen requirements for the system were defined so that the volume needed for field production and resources were minimized. Detrimental effects of high fluctuating temperatures can be anticipated so that the planting date may be changed later in the season to avoid low temperatures. These experiments supported efforts to design and build a cost-efficient soilless field production system for strawberry, providing the industry with a non-chemical alternative to pre-plant soil fumigation with methyl bromide.
Download or read book Handbook of Environmental Physiology of Fruit Crops written by Bruce Schaffer and published by CRC Press. This book was released on 2018-05-04 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: These exciting new companion handbooks are the only ones of their kind devoted solely to the effects of environmental variables on the physiology of the world's major fruit and nut crops. Their cosmopolitan scope includes chapters on tropical and temperate zone species written by scientists from several continents. The influence of environmental factors, such as irradiance, temperature, water and salinity on plant physiology and on vegetative and reproductive growth, is comprehensively discussed for each crop. In addition to being a thorough and up-to-date set of textbooks, the organzation of the two volumes makes them an excellent reference tool. Each chapter focuses on a single crop, or a group of genetically or horticulturally related crop, and is appropriately divided into subsections that address individual environmental factors. Some chapters emphasize whole-plant physiology and plant growth and development, while other chapters feature theoretical aspects of plant physiology. Several chapters provide botanical background discussions to enhance understanding of the crop's response to its environment.

This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Urban agriculture contributes to local food production, food access, nutrition, and community development in cities. Most research on crop productivity, however, takes place in rural environments, not in urban or peri-urban areas. Given a growing interest in urban agriculture, research evaluating factors that limit crop production in cities is needed as these factors may differ from those in rural environments. My dissertation research evaulates factor influencing strawberry (Fragaria x ananassa) cultivation in raised-bed production systems across rural, peri-urban, and urban environments. Strawberries are one of the most popular types of berries in the world and are well suited to grow in a variety of climatic and environmental conditions, including urban gardens and farms. My research aims to provide a better understanding of how genetic and environmental factors affect strawberry production via variation in plant interactions with beneficial and pest species, including pollinators, herbivores, and pathogens. This dissertation consists of five chapters. Chapter 1 provides background information on strawberry cultivation. Chapter 2 summarizes a three-year common garden experiment evaluating strawberry performance and functional trait variation among six cultivars grown at the Oakland University Student Organic Farm, a peri-urban farm located in Rochester Hills, MI, USA. Chapter 3 describes a three-year study to characterize pollinator abundance, diversity, and community composition at ten sites located across a rural-urban gradient in Southeast Michigan. Chapter 4 presents research examining how abiotic and biotic environmental factors influence strawberry production across these ten sites over the three-year study period. And, finally, Chapter 5 details a lab-based investigation involving three related experiments that aim to evaluate genotypic variation in post-harvest strawberry rot and the relationship between phytochemicals and pathogen growth. In Chapter 2, I describe annual variation in productivity as well as pathogen and pet damage within June-bearing and day-neutral cultivars. For June-bearing strawberries, Honeoye was the best performing cultivar, with the highest production and lowest damage. For day-neutral strawberries, Tribute produced the greatest fruit yield, but damage levels were comparable to the other cultivars. Overall, day-neutral cultivars were more productive compared with June-bearing, but this difference was due to cultivation methods that allow for an extra production year for day-neutral cultivars. June-bearing production was concentrated to a shorter harvest window, which is a desirable trait for some farmers. In Chapter 2, I discuss how trait trade-offs could influence cultivar selection for different types of strawberry growers. In Chapter 3, I show that urbanization had no effect on overall pollinator abundance, diversity, and community composition across sites and years. However, urbanization differentially influenced certain bee taxa, with some groups showing a negative association and others a positive association with urbanization. In general, sweat bees and small carpenter bees were the most dominant pollinators across sites and years, although honey bees were prominent at a few rural sites in year one. In Chapter 4, I demonstrate that urbanization did not directly affect productivity, although extreme temperatures associated with both cooler rural and warmer urban sites negatively impacted fruit set. Across the rural-urban gradient, strawberry yields were larger when bee visitation was relatively high, but a combination of pest and pathogen damage interfered with pollinator efficacy. Lastly, in Chapter 5, I show that phenotic compounds, namely p-Coumaric acid and quercetin, limited fungal growth during in vitro experimentation. In a follow-up experiment evaluating applications of phenolic compounds to fruit, there was no effect of p-Coumaric acid or an organic copper fungicide on post-harvest fruit rot due to pathogens. Post-harvest fruit rot, however, was suppressed by quercetin applications and significantly varied among cultivars - with Seascape showing the greatest susceptibility to pathogens. These results indicate that polyphenols and genotypic trait variation collectively influenced fruit rot, at least to some extent. All in all, my dissertation research contributes to informing cultivar selection and management strategies for raised-bed strawberry production in addition to a further understanding of context-dependent strawberry crop performance related to genetic and environmental variation.

Download or read book Factors Affecting Survival and Vigor of Cold stored Strawberry Nursery Stock written by Bruce Richard Decker and published by . This book was released on 1980 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: Field survivals of strawberry (Fragaria x ananassa) runner plants dug from December to April in both 1979 and 1980 were above 9C% when planted about May 1. When plants from the same digging dates were planted in early June, survival of March-dug 'Olympus' declined to 88% and survival of late-April-dug 'Totem' declined to 70% and 44% for 1979 and 1980 respectively. Field vigor mostly parallelled survival in 'Totem'. 'Olympus' vigor was 25% greater for April- versus January-dug stock when planted May 1, 1979, and evaluated after fifteen weeks. 1980 fruit yield per plant was also 25% greater in April- versus January-dug 'Olympus' planted May 1, 1979. However, January-dug 'Totem' outyielded late-dug plants by up to 25% for both early and late planting dates. Fungicide treatments, storage temperature, and nursery source did not significantly affect survival or vigor of March-dug 'Olympus' plants. Greenhouse root growth of January-dug plants was up to ten times greater than that of April-dug plants of both cultivars in 1979 and 1980. The incidence of apical damage, a possible result of cold-storage injury, increased from near zero for January- and February-dug plants to 50-90% for March- and April-dug plants. Storage temperatures of -3° to 0°C had little effect on plant quality, except for up to a three-fold increase in the incidence of apical rot for -3°C over 0°C storage. Carbohydrate concentrations showed a declining trend with later digging dates in both cultivars. In 'Totem', free sugars in roots declined by 60% from January to April in both years. Starch levels in 'Olympus' declined about 65% from a January high to a March low in 1980. Changes in carbohydrate status were associated with greenhouse root growth as well as survival and vigor in both the field and greenhouse. Plant viability and carbohydrate levels seemed related to weather preceding each digging date and developmental stage.
Download or read book Handbook of Fruit Set and Development written by Shaul. P Monselise and published by CRC Press. This book was released on 2018-01-18 with total page 578 pages. Available in PDF, EPUB and Kindle. Book excerpt: Different phases of fruit development and utilization have been treated in many textbooks, reviews, and a host of scientific and professional papers. This seems, however, to be the first attempt to bring together case histories of so many different fruits and to present a balanced account of the whole period from set to harvest. Postharvest physiology, which has been in the centre of the picture in many former books, is at the bored line of the subject matter of this book, and has not been fully covered, except in a few cases. For this reason, two separate chapters deal with physiological and pathological aspects of fruit life after harvest.

This book was released on 2013-12-11 with total page 299 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and dis seminated by the Center for Information and Numerical Data Analysis and Synthesis, (CINDAS) *at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the ac tivity was transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volume were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 19 (thesis year 1974) a total of 10,045 theses titles from 20 Canadian and 209 United States universities. We are sure that this broader base for theses titles reported will greatly enhance the value of this important annual reference work. The organization of Volume 19 is identical to that of past years. It consists of theses titles arranged by discipline and by university within each discipline.
