Available in PDF, EPUB and Kindle. Book excerpt: A micropropagation system was developed for hazelnut cultivars and rootstocks. Culture establishment was affected by explant source, explant collecting season, and type of explant. The highest frequency of culture initiation and lowest tissue oxidation and contamination were obtained from internodes with single axillary buds from grafted greenhouse-grown plants early in the growing season (March). Nodal explants had a higher percentage of growth than shoot tips. For field collected materials, suckers collected in mid-season were the best option. Tissue contamination and oxidation were the main problems for the in vitro establishment of explants from mature field-grown trees. Attempts to decrease tissue oxidation by using forced outgrowth from field-grown trees and treatment of explants with antioxidants were not successful. There was a correlation between explant oxidation and phenolic content. Shoot multiplication was the best on a modified DKW medium (NCGR-COR medium) supplemented with N6-benzyladenine (BA) (1.5-3 mg*1−1). Plants grown on medium with 3% glucose or fructose produced more and longer shoots than those on medium with sucrose. The general appearance and growth habit of shoots were better on medium with glucose than fructose. Shoot elongation varied with genotype. Changes in medium pH from 4.7 to 5.7 did not significantly affect the multiplication rate. Root formation was induced either in vitro by culturing shoots on NCGR-COR medium with half strength mineral salts and 1 mg*1−1 indole-3-butyric acid (IBA) for four weeks or ex vitro by a brief dip in 0.2 or 1 g*1−1 IBA and acclimatization. High transplant survival of plants was obtained. Internal bacterial contamination was present in micropropagated shoots. A combination of the antibiotics streptomycin and gentamicin was effective in eliminating contaminants from micropropagated shoots, but some phytotoxicity was noted. Adventitious shoots were induced at a low frequency from stem segments of 'Nonpareil', 'Willamette', and 'Tonda Gentile Romana' and leaf discs of 'Dundee' on medium containing glutamine, thidiazuron (TDZ), and naphthaleneacetic acid (NAA). Adventitious roots were produced from stem segments and leaf discs cultured on medium with NAA alone or high concentrations of a-NAA or IBA combined with low concentrations of BA.

This book was released on 2014 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: The branches and leaves of Salix matsudana Golden Spiral , willow, grow in a twisted manner, which makes it an important bonsai plant. Its mature stems have potential for the woody cut floral industry. Corylus colurna Te Terra Red, hazelnut, distinguished by red or purple leaves in the spring, has potential ornamental value in the horticulture industry for landscape use. Micropropagation of these two plants could provide more and healthier plantlets for rapid commercial scale-up by the nursery industry. Nas and Read Medium (NRM) is a newer medium developed specifically for hazelnut species by Nas and Read based on the composition of the seed. In this study, experiments were conducted to test whether NRM (with added plant growth regulators) is superior to other media such as Murashige and Skoog Medium (MS), Woody Plant Medium (WPM) and Driver-Kuniyuki Walnut medium (DKW) for shoot and root production of Salix and Corylus. The results showed that Salix explants grown in NRM with BA at 2.0mg/L and IBA at 0.05 mg/L produced a greater number of new shoots and longer stems. Explants grown in NRM with IBA at 0.05 mg/L produced more roots, which is necessary before transplanting to the soil. In addition, these plantlets exhibited deeper green color and acclimatized successfully into potential transplants. The hazelnut explants had a very high contamination rate and grew slowly on the various media. By improving disinfestation methods and by adding antibiotics in forcing solution and media, the contamination rate and browning rate can be decreased greatly.

This book was released on 2013-03-14 with total page 489 pages. Available in PDF, EPUB and Kindle. Book excerpt: While working in the laboratory of Professor Dr. Jacob Reinert at the Freie Universitat Berlin (1974-1976), I had the opportunity to become deeply involved in studying the intricacies of the fascinating phenomenon of somatic embryogenesis in plant cells and protoplasts. In numerous stimu lating discussions with Professor Reinert on this subject, I was fully convinced that somatic embryogenesis would become one of the most important areas of study, not only regarding basic and fundamental aspects, but also for its application in crop improvement. During the last decade, we have witnessed tremendous interest and achievements in the use of somatic embryos for the production of synthetic seeds, for micro propagation, genetic transformation, cryopreservation, and conservation of germplasm. The en masse production of somatic embryos in the bioreactors has facilitated some of these studies. Somatic embryos have now been induced in more than 300 plant species belonging to a wide range offamilies. It was therefore felt that a compilation ofliterature/state of the art on this subject was necessary. Thus, two volumes on Somatic Embryo genesis and Synthetic Seed have been compiled, which contain 65 chapters contributed by International experts. Somatic Embryogenesis and Synthetic Seed I comprises 31 chapters, arranged in 3 sections: Section I Commitment of the cell to somatic embryogenesis; early events; anatomy; molecular basis; gene expression; role of polyamines; machine vision analysis of somatic embryos. Section II Applications of somatic embryos; technology of synthetic seed; fluid drilling; micropropagation; genetic transfor mation through somatic embryos; cryopreservation.

Available in PDF, EPUB and Kindle. Book excerpt: 'frees contribute a major part of fuel, fodder and fruit, and are an im of bioenergy. They are now needed in large numbers more portant source than ever before for afforestation and social forestry, so that fast-grow ing and multipurpose trees assume great importance. After extensive in discriminate deforestation and rapid depletion of genetic stocks, efforts are now being made to evolve methods for clonal mass propagation of improved and elite trees. Production of short-duration trees with a rapid turnover of biomass, and induction of genetic variability through in vitro manipulation for the production of novel fruit and forest trees, which are high-yielding and resistant to pests and diseases, and trees which display increased photosynthetic efficiency are in demand. These objectives are well within the realm of horticultural and forest biotech nology. Some of the recent advances, such as the regeneration of com plete trees from isolated protoplasts, somatic hybridization, and the Agrobacterium-mediated transformation in various tree species have opened new vistas for the genetic engineering of fruit and forest trees. This book is a continuation of the earlier volume Trees I, and presents 31 chapters on fruit, forest, nut and ornamental trees, such as avocado, pineapple, crabapple, quince, pistachio, walnut, hazelnut, date palm, oil palm, cacao, rubber, maple, sweet-gum, poplars, birches, Chinese tallow, willows, oaks, paper mulberry, rhododendrons, Scots pine, Calabrian pine, Douglas-fir, redwood, ginkgo, cycads and some flowering trees.
Download or read book Meta topolin A Growth Regulator for Plant Biotechnology and Agriculture written by Naseem Ahmad and published by Springer Nature. This book was released on 2021-05-02 with total page 339 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant tissue culture (PTC) technology has gained unassailable success for its various commercial and research applications in plant sciences. Plant growth regulators (PGRs) are an essential part of any plant tissue culture intervention for propagation or modification of plants. A wide range of PGRs are available, including aromatic compounds that show cytokinin activities, promote cell division and micro-propagation, viz. kinetin, N6-benzyladenine and topolins. Topolins are naturally occurring aromatic compounds that have gained popularity as an effective alternative for other frequently used cytokinins in in vitro culture of plants. Among them, meta-topolin [6-(3-hydroxybenzlyamino) purine] is the most popular and its use in plant tissue culture has amplified swiftly. During the last few decades, there have been numerous reports highlighting the effectiveness of meta-topolin in micropropagation and alleviation of various physiological disorders, rooting and acclimatization of tissue culture raised plants.
Download or read book Protocol for Somatic Embryogenesis in Woody Plants written by Shri Mohan Jain and published by Springer Science & Business Media. This book was released on 2005-05-23 with total page 604 pages. Available in PDF, EPUB and Kindle. Book excerpt: World population is increasing at an alarming rate and this has resulted in increasing tremendously the demand for tree products such as wood for construction materials, fuel and paper, fruits, oils and medicines etc. This has put immense pressure on the world’s supplies of trees and raw material to industry and will continue to do so as long as human population continues to grow. Also, the quality of human diet, especially nutritional components, is adversely affected due to limited genetic improvement of most of fruit trees. Thus there is an immediate need to increase productivity of trees. Improvement has been made through conventional breeding methods, however, conventional breeding is very slow due to long life cycle of trees. A basic strategy in tree improvement is to capture genetic gain through clonal propagation. Clonal propagation via organogenesis is being used for the production of selected elite individual trees. However, the methods are labour intensive, costly, and produce low volumes. Genetic gain can now be captured through somatic embryogenesis. Formation of embryos from somatic cells by a process resembling zygotic embryogenesis is one of the most important features of plants. In 1958, Reinert in Germany and Steward in USA independently reported somatic embryogenesis in carrot cultures. Since then, tremendous progress in somatic embryogenesis of woody and non-woody plants has taken place. It offers a potentially large-scale propagation system for superior clones.

This book was released on 2007-09-18 with total page 548 pages. Available in PDF, EPUB and Kindle. Book excerpt: Micropropagation has become a reliable and routine approach for large-scale rapid plant multiplication, which is based on plant cell, tissue and organ culture on well defined tissue culture media under aseptic conditions. A lot of research efforts are being made to develop and refine micropropagation methods and culture media for large-scale plant multiplication of several number of plant species. However, many forest and fruit tree species still remain recalcitrant to in vitro culture and require highly specific culture conditions for plant growth and development. The recent challenges on plant cell cycle regulation and the presented potential molecular mechanisms of recalcitrance are providing excellent background for understanding on totipotency and what is more development of micropropagation protocols. For large-scale in vitro plant production the important attributes are the quality, cost effectiveness, maintenance of genetic fidelity, and long-term storage. The need for appropriate in vitro plant regeneration methods for woody plants, including both forest and fruit trees, is still overwhelming in order to overcome problems facing micropropagation such as somaclonal variation, recalcitrant rooting, hyperhydricity, polyphenols, loss of material during hardening and quality of plant material. Moreover, micropropagation may be utilized, in basic research, in production of virus-free planting material, cryopreservation of endangered and elite woody species, applications in tree breeding and reforestation.
