Book Description
Seed Quality: Basic Mechanisms and Agricultural Implications focuses on various aspects of seed quality and integrates research at basic and applied levels, supporting high-quality seeds as the basis of higher agricultural productivity. With its clear perspective and interdisciplinary focus on basic and applied aspects of seed quality, this book is immensely useful to students and teachers in many agricultural and botanical disciplines. Because seed quality is a critical component in the economic considerations of the farmer and the seedman alike, Basra looks in-depth at these aspects of seed production: seed viability seed health seed vigor seed testing variety identification crop yield seed storage seed production seed deterioration seed treatments Seed quality is of international agronomic concern, and the recent upsurge of interest in seed quality has accentuated a new awareness regarding its importance in crop production. This book meets the need for information and could form the basis of long-range planning by policymakers on quality assurance and management programs and in the facilitation of international trade. Researchers, students, and teachers in many agricultural and botanical disciplines--seed science and technology in particular--will find this book to be of immense use. It can be used as a handbook for those involved in seed industry and seed testing services. It is recommended for international courses in seed science and technology and seed training programs.

Book Description
The consumer demand for organically produced dry beans (Phaseolus vulgaris L.) continues to increase in the U.S. Organic farmers are faced with production and harvest challenges that impact the processing and end-use quality of dry beans. One major challenge is seed coat mechanical damage induced during harvest, which is a concern for both organic and conventional growers, but the latter has more tools to manage harvest to reduce the impact of the damage. The goal of this research is to improve organic dry bean end-use quality by exploring the genetic variability for mechanically induced seed coat damage, developing enhanced end-use product processing methods, and investigating the variations in seed quality related characteristics. Kidney and black bean market classes are the focus of this work due to their importance in organic production and challenges with end-use quality, especially seed coat splitting and canning quality. Genetic variability for seed coat splitting was evaluated in a collection of 61 kidney beans from three market classes including dark red kidney (DRK), light red kidney (LRK), and white kidney (WK) beans. The beans were harvested under two conditions to induce mild and severe seed coat damage as well as the downstream processing quality of the beans. LRK was found to be more susceptible to seed coat damage than the other two market classes with the highest average seed coat check (SCC) severity score. Genotypes less susceptible to seed coat damage than others were identified within each market class. Seed coat thickness was found not to be a good indicator for SCC severity. SCC severity scores and canning quality appearance scores were found to be negatively correlated. SCC severity score of combine threshed seeds can be used as a selection factor in variety improvement for resilience to mechanical damage. Canning and pouch processing methods were further explored as means to add value to organically produced beans. Pilot-scale pouch and canning processing protocols were developed and updated for use in dry bean breeding programs. The protocols included innovative virtual quality evaluation methods and methods to improve the processing quality of organic dry beans. Both methods were utilized with dry beans from different market classes to test the methods and identify the expected variations in processing quality. A harvest survey was conducted with participation from Michigan bean growers. Nine out of 22 black bean samples had a higher than 20% SCC percentage which is considered unacceptable in the industry standard. In general, variations in mechanical seed coat damage is a result of a series of factors including the genetics of the seeds, the seed moisture content, the environmental condition, and℗ the operation of harvest method. The end-use quality of organic dry beans can be enhanced using the identified genetic variability and improved processing methods.℗

Book Description
Seeds of two Brazilian varieties of dry beans, Rosinha and Carioca, were stored at 20o and 30oC and 75% R. H. The progress and extent of deterioration during storage was evaluated by means of standard germination, accelerated aging, root growth, tetrazolium and chemical soak tests. Seed of both varieties were also adjusted to 13.8% moisture content, sealed in glass containers and rapidly aged at 45oC to obtain different deterioration or vigor levels. Three vigor levels--high, medium and low--were selected for field performance studies on the basis of rate of root growth and response to accelerated aging treatments. In the storage studies loss of vigor was manifested by a reduction in average root length, a lowered resistance to accelerated aging, an increased permeability of cell membranes, and a reduction in enzymatic redox activity. Loss of vigor preceded a decrease in viability under both storage conditions. Results of field tests indicated that the consequences of planting low quality bean seeds were slower emergence and early seedling growth, reduced stands, less uniformity in plant growth, late flowering, and decreased yield. Of the quality tests evaluated, root growth and tetrazolium reaction were most efficient in detecting the extent and rate of deterioration during storage. Accelerated aging was most effective in predicting the storability of the two lots and in monitoring the progressive loss of vigor.
