Meta-topolin: A Growth Regulator for Plant Biotechnology and Agriculture


Book Description

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.




Biostimulants for Crops from Seed Germination to Plant Development


Book Description

Biostimulants for crops from seed germination to plant development focuses on the effects and roles of natural biostimulants in every aspect of plant growth development to reduce the use of harmful chemical fertilizers and pesticides. Biostimulants are a group of substances of natural origin that offer a potential to reduce the dependency on harmful chemical fertilizers causing environmental degradation. While there is extensive literature on biostimulants, there remains a gap in understanding how natural biostimulants work and their practical application. This book fills that gap, presenting the ways in which biostimulants enhance seed vigor and plant productivity by looking into their mode of action, an area still being researched for deeper understanding. Exploring the roles of seed germination, pollen tube formation, pollen-pistil interaction, flower and fruit setting, to plant pigments, rhizospheric and soil microorganisms, the book also sheds light on the challenges and realistic opportunities for the use of natural biostimulants. - Approaches biostimulant research with the goal of transforming scientific research into practical application - Includes real-world examples from laboratory, greenhouse and field experiments - Presents the biochemical, physiological and molecular mode of action of biostimulants




Plant Growth Regulators in Agriculture and Horticulture


Book Description

As agriculture becomes more mechanized and science increases the possibilities for using inputs to enhance production, the role of PGRs becomes more vital. Plant Growth Regulators in Agriculture and Horticulture provides agriculture professionals and researchers with the information needed to effectively tap these versatile resources to enhance crop production. Through discussions of the “classical five” phytohormones--gibberellins, cytokinins, ethylene, abscisic acid, and auxins--and the growing number of nontraditional PGRs such as oligosaccharins and brassinosteroids, Plant Growth Regulators in Agriculture and Horticulture reviews past and present uses of PGRs in managing crop yield and offers some speculation on future directions. Detailed discussions on the use of PGRs in, for example, grain, ornamental, and citrus crops, introduce readers to strategies for enhancing crop quantity and quality, for improving the postproduction quality of life of perishable plants, and for crop load management, respectively. The book also includes informative visuals, such as tables of common, chemical, and trade names of different commercially available PGRs; diagrams of various PGR processes; as well as before-and-after pictures illustrating the effects of PGRs. Plant Growth Regulators in Agriculture and Horticulture is a comprehensive text covering the role of plant growth regulators in: root formation manipulating yield potential plant stress protection ornamental horticulture postharvest life of ornamentals manipulating fruit development and storage quality citriculture reducing fruit drop bloom-thinning strategies If the history of agriculture, which is over 10,000 years old, was condensed into a twenty-four-hour span, science-based plant breeding would be only about fifteen minutes old. Still, the role of PGRs in agriculture is modest compared to other agrochemicals, such as fungicides, herbicides, and insecticides. Plant Growth Regulators in Agriculture and Horticulture is an invaluable guide to the varied roles filled by PGRs in the attainment of higher-quality, better-yielding crops.

Temperate Fruits


Book Description

This book was first published in 1991 and was well received by students, teachers and researchers in many universities and institutes in India and abroad. In the past 28 years (since its first publication), tremendous progress have been made in temperate fruit research, notably in developing varieties and rootstocks, canopy management, understanding the flowering physiology, storage technology, biological control of pests and diseases, resistance breeding, biotechnology, etc., Revision of the book with updated information was considered necessary. In the process of a comprehensive literature survey it was felt impossible to compile all the information in one volume. This enlarged edition on temperate fruits is, therefore, published in tow volumes. The first volume consists of pome and stone fruits (apples, pears, peaches, plums, apricots and cherries) in more than 550 pages. The second volume deals with temperate nuts and berries (almonds, chestnuts, hazelnuts, pecans, pistachios, walnut, strawberries, currants, gooseberries, raspberries, blueberries and cranberries) in about 650 pages. Apart from through revision with updated scientific information on various aspects of mentioned pome, stone, nuts and berries, substantial reorganization of the text has been made. Emphasis has been laid to include released cultivars and rootstocks, recent trends in propagation and orchard management, pruning and canopy management, nutrition and tissue analysis, water management, improved technology for harvesting, postharvest handling, storage and ripening. Special emphasis has been laid to include the development in breeding and improvement through biotechnological approaches like molecular markers, genetic transformation, genetic map and microbes for N and P input. Other information like organic production technology, protected cultivation and impact of climate change are included, where sufficient information is available. Though the subject is vast, this two volumes book presents the concepts in a condensed, informative and lucid manner. It will be immense help to the students, teachers and researchers of horticulture, plant science, plant physiology and plant protection.




Growth Regulators and Biostimulants: Upcoming Opportunities


Book Description

In the recent past, significant strides have been made in the domain of plant growth regulators (PGRs) and biostimulants. In the sustainable utilization of plant germplasm PGRs and biostimulants play a pivotal role. With a magnified growth rate and less risk of inducing clonal somaclonal variations, PGRs (such as auxins, gibberellins, isoprenoid and aromatic cytokinins, ethylene, and abscisic acid) serve as a boon to plant biologists especially those working with rare endangered and threatened species and medicinal and aromatic plant species. Furthermore, the combined effect of PGRs with LEDs (light-emitting diode) on various aspects of plant development is an area of research gaining attention. The use of biostimulants to promote plant growth, yield and stress tolerance has increasingly gained attention. However, their functional role in the growth and development of plants is not clearly understood.
