Seed Dormancy and Germination

Seed Dormancy and Germination

Seed dormancy is a physiological phenomenon in plants, which is caused by external or internal factors, and prevent of seeds germination, even in optimal conditions. Seed dormancy may be caused due to hard seed coat, immature embryo, rudimentary embryo and inhibitors materials. Seed dormancy is broken with soil melting and freezing, microorganism’s activity, forest fires, soil activity, and being eaten by animals, in normal conditions.This book explains the causes of seed dormancy, morphological, physiological and metabolic changes in seeds during and after dormancy breaking and the new methods for breaking seed dormancy.

Dormancy Breaking and Germination of Rice Seed

Dormancy Breaking and Germination of Rice Seed

The importance of rice for our country is manifold as it is an agricultural commodity that adds 20% FEC to the national foreign exchange reserves. Seed is a living tissue carries a genetic potential.Failing of seeds to germinate under environmental conditions optimal for germination is called dormancy. True dormancy caused by the conditions within the seed that prevent germination. Thus dormancy is a state of seed, not of the environment, that reduces seed germination and breaking dormancy ,could be one of the most important factor for early germination. Whereas the wild species of rice offer an important source of variability for improvement of cultivated rice. Keeping in view of its importance the present work has been attempted to break dormancy of both the wild species and cultivated rice with different treatments. The outcome of breaking dormancy was the early germination, to increase survival percentage,shorten the nursery period and reduced maturity days.This book describe all the possible dormancy breaking methods of wild species and cultivated varities of rice. This may be helpful & used as protocol in future research studies by researchers.

Potato Dormancy, Sprouting and Tuberization

Potato Dormancy, Sprouting and Tuberization

Dormancy is one aspect of tuber physiological age that begins with potato tuber initiation. During dormancy, proteomic and physiological processes do happen but they do not lead to immediate morphological changes. But these processes are relevant for the number of sprouts produced after breaking of the dormancy and for the growth vigour of the seed tuber. This review propose that dormancy phasis is a complex process that depends mainly on genetic background, stage of tuber development, environmental and management conditions during tuber growth and storage, it also depends of mother tuber. In addition, temperature, humidity, water supply, as well as the photoperiod during plant growth are important environmental factors that regulate potato tuber sprouting. Storage temperature and gas composition regulate dormancy breaking. Many chemicals are used to break dormancy in potato. Hormonal regulation through endogenous an exogenous phytohormones is primordial in controlling dormancy, sprouting and tuberization in potato.

On Some Iterative Methods for Solving System of Nonlinear Equations

On Some Iterative Methods for Solving System of Nonlinear Equations

Various problems of pure and applied sciences such as physics, chemistry, biology, engineering, economics, management sciences, industrial research and optimization can be studied in the unified frame work of the system of nonlinear equations. In this study, we develop several new iterative methods for solving a system of nonlinear equations by using different techniques, including quadrature technique, new decomposition method and variational iteration technique. We prove the convergence of the new methods. We obtain the upper bounds of the error of new methods. We also discuss the efficiency index of the proposed methods and compare it with some other well-known methods. We provide several examples for the implementation and performance of the new methods. Comparison with some other existing methods is also given. We also discuss some open research problems.

Laboratory Methods for Pharmacological Activity Study

Laboratory Methods for Pharmacological Activity Study

To search new and newer agents to the combat the modified as well as existing and new ill effects is a great challenge today. Availability of easy, economy and more quick methods for the evaluation of test drugs is also a key to successes. It is also helpful for the discovery and development of drugs from natural, synthetic and semi-synthetic pathways. To develop some laboratory test methods for pharmacological evaluation of crude/drugs. Ease of handling, less time consuming and economy are also a major consideration here.
