This book was released on 1969 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seed of Deltapine 16 and hopicala cotton (Gossypium hirsutum L.) were tested under laboratory conditions in 1968 for germination salt tolerance with sodium-, calcium-, and magnesium chloride alone and in the tri-salt combination using two temperatures at the University of Arizona, Tucson. Beginning the fourth day, germination counts were continued daily through the 12th day. A seed was considered germinated when the total length of the epicotyl and root were 5 cm or more. Seed of the cultivars tested differed in their ability to germinate in saline solutions. Deltapine 16 was more salt tolerant than Hopicale. The types of salts did not differentially affect seed germination. The rate of germination decreased qith increased salt concentration. Temperatures differentially affected the rate of germination. Low temperature retarded germination compared to high temperature. Significant interactions of the first and second order indicated that seed of both cultivars did not germinate similarly at the both cultivars did not germinate similarly at the various salt concentrations under different temperatures. The rate of germination of both cultivars was reduced at the low temperature treatment compared to the high temperature. Also, increasing salinith delayed seed germination. Retardation of seed germination with increasing salinity was more severe at the low temperature treatment than at the high temperature. Also, increasing salinity delayed seed germination. Retardation of seed germination with increasing salinity was more severe at the low temperature treatment than at high temperature.

Available in PDF, EPUB and Kindle. Book excerpt: Environmental insults such as extremes of temperature, extremes of water status as well as deteriorating soil conditions pose major threats to agriculture and food security. Employing contemporary tools and techniques from all branches of science, attempts are being made worldwide to understand how plants respond to abiotic stresses with the aim to help manipulate plant performance that will be better suited to withstand these stresses. This book on abiotic stress attempts to search for possible answers to several basic questions related to plant responses towards abiotic stresses. Presented in this book is a holistic view of the general principles of stress perception, signal transduction and regulation of gene expression. Further, chapters analyze not only model systems but extrapolate interpretations obtained from models to crops. Lastly, discusses how stress-tolerant crop or model plants have been or are being raised through plant breeding and genetic engineering approaches. Twenty three chapters, written by international authorities, integrate molecular details with overall plant structure and physiology, in a text-book style, including key references.

Book excerpt: This volume provides a collection of protocols aimed toward the study of ethylene signaling in plants. Ethylene Signaling: Methods and Protocols is divided into three sections: ethylene biosynthesis, the signal transduction pathway, and the diverse ethylene responses of dicots and monocots. The chapters in section one discuss techniques for the measurement of activities related to the biosynthetic enzymes ACC synthase and ACC oxidase, the levels of ethylene synthesized by plants, and the treatment of plants with exogenous ethylene. Section two focuses on the analysis of the new membrane-associated proteins involved in the initial perception and transduction of the ethylene signal, such as ethylene receptors, CTR1, and EIN2. The third section covers assays applicable to dicots and monocots, including methods related to the roles of ethylene in germination, growth, abscission, abiotic stress, and defense. Section three also includes information on Arabidopsis mutants and the variety of chemical inhibitors that affect ethylene responses. Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Thorough and comprehensive, Ethylene Signaling: Methods and Protocols is a valuable resource for both experienced and beginner researchers with prior experience in the study of ethylene signaling and for those who are just entering this exciting research field.

Download or read book New Frontiers in Stress Management for Durable Agriculture written by Amitava Rakshit and published by Springer Nature. This book was released on 2020-03-23 with total page 663 pages. Available in PDF, EPUB and Kindle. Book excerpt: Using accessible farming practices to meet the growing demands on agriculture is likely to result in more intense competition for natural resources, increased greenhouse gas emissions, and further deforestation and land degradation, which will in turn produce additional stress in the soil-water-plant-animal continuum. Stress refers to any unfavorable force or condition that inhibits customary functioning in plants. Concurrent manifestations of different stresses (biotic and abiotic) are very frequent in the environment of plants, which consequently reduces yield. Better understanding stress not only changes our perspective on the current environment, but can also bring a wealth of benefits, like improving sustainable agriculture and human beings’ living standards. Innovative systems are called for that protect and enhance the natural resource base, while increasing productivity via ‘holistic’ approaches, such as agroecology, agro-forestry, climate-smart agriculture and conservation agriculture, which also incorporate indigenous and traditional knowledge. The book ‘New Frontiers in Stress Management for Durable Agriculture’ details the current state of knowledge and highlights scientific advances concerning novel aspects of plant biology research on stress, biotic and abiotic stress responses, as well as emergent amelioration and reclamation technologies to restore normal functioning in agroecology.
