Download or read book Growth and Quality Formation Regulated by Light in Horticulture Plants written by Houcheng Liu and published by Frontiers Media SA. This book was released on 2024-05-27 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: Horticultural crop production plays an important role in the global food supply, and horticultural plants contain numerous health-promoting phytochemicals, such as vitamins, flavonoids, polyphenols, and other secondary metabolites. The formation of yield and nutritional quality depends on the intrinsic characteristics of horticultural crops and environmental conditions. Light is the primary energy source for photosynthesis, and light, ranging from UV to far-red, is a critical factor in regulating plant growth, morphogenesis, development, and metabolic processes. The physiological and molecular regulation of plant processes is related to the intensity, spectrum, direction, photoperiod, and timing of light. And light is the most important environmental factor determining the yield and quality of horticultural crops.
Download or read book Light and Plant Growth written by J.W. Hart and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are many recent works on the topic of light and plant growth. These have not only been written by experts, but are also, in the main, written for experts (or, at least, for those who already have a fair understanding of the subject). This book has its origins in a six-week course in plant photophysiology, and its aim is to provide an introduction to the subject at an advanced undergraduate level. The imagined audience is simply a student who has asked the questions: In what ways does light affect plant growth, and how does it do it? The book is limited to aspects of photomorphogenesis. Photo synthesis is only considered where its pigments impinge on photo morphogenic investigations, or where its processes provide illustrative examples of particular interactions between light and biological material. Chapter 1 gives a general account of the various ways in which light affects plant development, and introduces topics which are subsequently covered in greater detail. In all the chapters, are special topic 'boxes', consisting of squared-off sections of text. These are simply devices for presenting explanatory background material, or material that I myself find particularly intriguing.

Download or read book The Effects of LED Light Spectra and Intensities on Plant Growth written by Valeria Cavallaro and published by Mdpi AG. This book was released on 2023-04-18 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Light is the main source of energy for the primary process that sustains life on our planet, known as photosynthesis. Photosynthesis is the strategy adopted by many living organisms for capturing and incorporating energy, and it is under this context that light is primarily experienced, explored, and exploited. Plants perceive information from the ambient environment and communicate with other organisms using light. They have developed a plethora of photoreceptors that permit this communication with the surrounding environment. Additionally, the physical properties of light, such as the spectral quality, irradiance, intensity, and photoperiod, play an integral role in the morphogenesis, growth, and metabolism of many biochemical pathways in plants. To facilitate photosynthesis in controlled environments, light‐emitting diodes (LEDs) have been shown to offer interesting prospects for use in plant lighting designs in controlled-environment agriculture (greenhouses) and growth chambers for in vitro cultures. In high-technology greenhouses (for instance, vertical agriculture), artificial light may assume both assimilative (optimizing photosynthetic efficiency) and control functionality (guiding growth and development or the synthesis and accumulation of plant metabolites). In vitro cultures are regulated by different factors, and among them, light is the most important.

Download or read book Controlled Environment Horticulture written by Christoph-Martin Geilfus and published by Springer Nature. This book was released on 2019-08-21 with total page 233 pages. Available in PDF, EPUB and Kindle. Book excerpt: An understanding of crop physiology and ecophysiology enables the horticulturist to manipulate a plant’s metabolism towards the production of compounds that are beneficial for human health when that plant is part of the diet or the source of phytopharmaceutical compounds. The first part of the book introduces the concept of Controlled Environment Horticulture as a horticultural production technique used to maximize yields via the optimization of access to growing factors. The second part describes the use of this production technique in order to induce stress responses in the plant via the modulation of these growing factors and, importantly, the way that this manipulation induces defence reactions in the plant resulting in the production of compounds beneficial for human health. The third part provides guidance for the implementation of this knowledge in horticultural production.

This book was released on 2017-03-22 with total page 205 pages. Available in PDF, EPUB and Kindle. Book excerpt: The plant factory is a facility that aids the steady production of high-quality vegetables all year round by artificially controlling the cultivation environment (e.g., light, temperature, humidity, carbon dioxide concentration, and culture solution), allowing growers to plan production. By controlling theinternal environment,plant factories can produce vegetables about two to four times faster than by typical outdoor cultivation. In addition, as multiple cultivation shelves (a multi-shelf system) are used, the mass production of vegetables in a small space is facilitated. This research topic presents some new trends on intelligent measuring systems; environment controlled and optimization; flavonoids; phenylpropanoids, transcriptomes, and bacteria.
Download or read book Impact of Light on Horticultural Crops written by Athanasios Koukounaras and published by Mdpi AG. This book was released on 2023-07-05 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Light is an essential factor for the growth and quality of horticultural plants and its effects depend upon parameters such as duration, intensity and quality. It is an energy source for photosynthesis as well as a signal triggering plant photomorphogenesis and physiological, biochemical and molecular responses. However, solar light strongly differs between winter and summer conditions, with excess light in open field cultivations imposing severe stress on plants, especially during summer months, while supplementary light sources are implemented in greenhouse crop production to complement natural light when it is insufficient. On the other hand, artificial lighting is used as the sole lighting source in plant factories and nurseries (i.e., healing chambers, plant tissue culture). In order to enhance sustainability and profitability, light must be studied and efficiently applied within horticultural crop production. Novel technologies such as light-emitting diodes, new transparent greenhouse covering materials, photoselective nettings, growth chambers and plant factories showcase the critical role of light interacting with plants from the level of seed germination to growth rate, product quality and postharvest storage. This Special Issue focuses on recent findings in horticultural crops with regard to light characteristics (i.e., quality, quantity etc.) presented as research papers, short communications and review articles.
Download or read book Light emitting Diode Lighting Quality Effects on Morphology Growth Flowering and Carotenoid Content of Potted Plant Cut Flower and Medicinal Flower Production written by Yihe Zou and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: With the development of controlled environment agriculture (CEA), light emitting diode (LED) lighting is used as one of the sources of energy and the regulator for plant growth and development. Plant morphology, growth, productivity, and nutritional quality can be regulated by light quality, intensity, and photoperiod. LED lighting was widely used in horticultural research in the past 20 years. In our studies, LED lighting was used as the sole light source for indoor marigold production and supplemental light for potted geranium, gerbera, and cut rose production. In Chapter 1 we explored the effects of within-canopy LED lighting on plant morphology, flowering, and different impacts of various spectral LED light irradiating abaxial sides of potted plants. Red LED light showed great advantages in increasing peduncle number for geranium and increasing scape length for gerbera. The objective of Chapter 2 was to evaluate the effect of LED lighting on the bent canopy of cut roses. LED lighting did not have a significant effect on promoting cut rose stem elongation or increasing cut rose flower production due to the limitation of energy input, reduction in leaf net photosynthesis, stomatal conductance, and transpiration rate of bent stems. Chapter 3 was to test various effects of LED light with monochromatic red, blue and the various ratios of red/blue combinations on marigold morphology, growth, flowering, and carotenoid content from petals. Results showed marigold grown under 75R:25B and 50R:50B treatment were more compact. Shoot fresh weight (FW), shoot dry weight (DW), leaf fresh weight (FW), and leaf dry weight (DW) were significantly increased under the White treatment and reduced under Blue treatment, which indicated that both red and blue light are important for plant biomass accumulation. In addition, blue light can stimulate flower bud initiation as well as increasing the carotenoid content accumulation in petals.
