Cultivars written by Lekkala Vijayasimha Reddy and published by . This book was released on 1978 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Effect of temperature on seed dormancy, alpha-amylase activity and kernel weight in five wheat (Triticum aestivum L.) varieties was studied. Three ripening temperature conditions - 15.5°C, 26.6 °C and "Field" were used to induce dormancy. Alpha-amylase activity and kernel weight of developing kernels was determined every ten days after anthesis until maturity. Dormancy in kernels was examined at germination temperatures of 15. 5°C, 20°C and 26. 6°C. Alpha- amylase activity during germination of kernels was determined on 1st, 2nd, 3rd and 6th day. In developing kernels alpha-amylase activity peaked at 10 to 20 days after anthesis and dropped or levelled-off as the kernels approached maturity. This was observed at both 15.5°C and 26.6° C . However, the peak was not obvious at 26.6°C because of the enzyme activity was lower at this temperature than at 15.5°C. In kernels ripened in field, the enzyme activity fluctuated apparently depending upon the changes in weather conditions, especially temperature. A faster growth of kernels and higher final dry kernel weight were noticed at 26.6°C and field temperature conditions than at 15.5°C. Significant varietal differences were observed in both alpha-amylase activity in kernels and kernel weight during the development and maturation of kernels. Kernels of all varieties, ripened at 26.6 °C, germinated as fast as non-dormant check kernels at 15.5°C but exhibited varying degrees of dormancy when germinated at 20 °C and 26.6°C. In contrast, kernels of Brevor, Tom Thumb and P.I. 178211, ripened at 15.5 °C showed a high level of dormancy as shown by their failure to germinate at 20 °C and 26.6 °C, and slow germination at 15.5° C. Kernels of Hyslop and Yamhill, ripened at 15.5°C, did not show dormancy at 15.5°C but showed some dormancy at 20°C and 26.6°C. This dormancy, however, was less than in Brevor, Tom Thumb and P.I. 178211. Field ripened kernels of Yamhill and Hyslpp when germinated at 15.5°C, did not show any dormancy; whereas, P.I. 178211, Brevor and Tom Thumb expressed different degrees of dormancy. Kernels of all varieties, ripened in the field, when germinated at 20°C or 26.6 °C, showed different degrees of dormancy except Yamhill. Yamhill did not differ significantly from the one year old non-dormant check kernels at 26.6° C . A substantial increse in alpha-amylase occurred only in germinated kernels. Although kernels of all varieties ripened at 26.6°C showed about the same weighted germination percentage at 15.5°C, germinated kernels of Yamhill, Hyslop and P.I. 178211 and had highly significant greater alpha-amylase activity than those of Brevor and Tom Thumb. In general, lower alpha-amylase activity was observed at higher germination temperatures. However, the data indicate that the enzyme activity depends to some extent on the ripening temperature conditions. Thus the results indicated that seed dormancy, alpha-amylase activity and kernel weight are determined by the genotype of a variety and influenced by the temperature during maturation and germination of kernels.

Available in PDF, EPUB and Kindle. Book excerpt: Pre-harvest sprouting (PHS) and late-maturity alpha-amylase (LMA) are two of the biggest grain quality defects that grain growers encounter. About 50 percent of the global wheat crop is affected by pre-harvest sprouting to various degrees. Pre-harvest sprouting is a genetically-based quality defect and results in the presence of alpha-amylase in otherwise sound mature grain. It can range from perhaps undetectable to severe damage on grain and is measured by the falling numbers or alpha-amylase activity. This is an international issue, with sprouting damage lowering the value of crops to growers, seed and grain merchants, millers, maltsters, bakers, other processors, and ultimately the consumer. As such it has attracted attention from researchers in many biological and non-biological disciplines. The 13th International Symposium on Pre-Harvest Sprouting in Cereals was held 18-20 September, 2016 in Perth to discuss current findings of grain physiology, genetic pathways, trait expression and screening methods related to pre-harvest sprouting and LMA. This event followed the previous symposium in 2012 in Canada.

This book was released on 2011-12-02 with total page 523 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate change is a complex phenomenon with a wide range of impacts on the environment. Biotic and abiotic stress are a result of climate change. Abiotic stress is caused by primary and secondary stresses which are an impediment to plant productivity. Prolonged exposure to these stresses results in altered metabolism and damage to biomolecules. Plants evolve defense mechanisms to withstand these stresses, e.g. synthesis of osmolytes, osmoprotectants, and antioxidants. Stress responsive genes and gene products including expressed proteins are implicated in conferring tolerance to the plant. This volume will provide the reader with a wide spectrum of information, including vital references. It also provides information as to how phytoconstituents, hormones and plant associated microbes help the plants to tolerate the stress. This volume also highlights the use of plant resources for ameliorating soil contaminants such as heavy metals. Dr. Parvaiz is Assistant professor in Botany at A.S. College, Srinagar, Jammu and Kashmir, India. He has completed his post-graduation in Botany in 2000 from Jamia Hamdard New Delhi India. After his Ph.D from the Indian Institute of Technology (IIT) Delhi, India in 2007 he joined the International Centre for Genetic Engineering and Biotechnology, New Delhi. He has published more than 20 research papers in peer reviewed journals and 4 book chapters. He has also edited a volume which is in press with Studium Press Pvt. India Ltd., New Delhi, India. Dr. Parvaiz is actively engaged in studying the molecular and physio-biochemical responses of different plants (mulberry, pea, Indian mustard) under environmental stress. Prof. M.N.V. Prasad is a Professor in the Department of Plant Sciences at the University of Hyderabad, India. He received B.Sc. (1973) and M.Sc. (1975) degrees from Andhra University, India, and the Ph.D. degree (1979) in botany from the University of Lucknow, India. Prasad had published 216 articles in peer reviewed journals and 82 book chapters and conference proceedings in the broad area of environmental botany and heavy metal stress in plants. He is the author, co-author, editor, or co-editor for eight books. He is the recipient of Pitamber Pant national Environment Fellowship of 2007 awarded by the Ministry of Environment and Forests, Government of India.

Book excerpt: The appearance of the new generation in higher plants is ensured by the presence of viable seeds in the mother plant. A good number of signaling networks is necessary to provoke germination. Phytohormones play a key role in all stages of seed development, maturation, and dormancy acquisition. The dormancy of some seeds can be relieved through a tightly regulated process called after-ripening (AR) that occurs in viable seeds stored in a dry environment. Although ABA is directly involved in dormancy, recent data suggest that auxin also plays a preponderant role. On the other hand, the participation of reactive oxygen species (ROS) in the life of the seed is becoming increasingly confirmed. ROS accumulate at different stages of the seed’s life and are correlated with a low degree of dormancy. Thus, ROS increase upon AR and dormancy release. In the last decade, the advances in the knowledge of seed life have been noteworthy. In this Special Issue, those processes regulated by DOG1, auxin, and nucleic acid modifications are updated. Likewise, new data on the effect of alternating temperatures (AT) on dormancy release are here present. On the one hand, the transcriptome patterns stimulated at AT that encompasses ethylene and ROS signaling and metabolism together with ABA degradation were also discussed. Finally, it was also suggested that changes in endogenous γ-aminobutyric acid (GABA) may prevent seed germination.
