Download or read book Effect of Soil Temperature Seeding Date and Straw Mulch on Plant Development and Grain Yield of Two Winter Wheat and Two Winter Barley Cultivars written by Alpaslan Pehlivantürk and published by . This book was released on 1975 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two winter wheat (Triticum aestivum L. em Thell) and two winter barley (Hordeum vulgare L. em Thell) cultivars were grown with and without straw mulch utilizing six different planting dates. Soil temperature was recorded continuously at seeding depth from planting date through March of the crop year. A series of thermocouples connected to a point recorder were used for the soil temperature measurements. Soil temperature data were condensed through the use of a computer to obtain monthly averages for fallow treatments (bare and straw mulch) and diurnal variations. Plant growth in terms of days to emergence and days to tillering was noted for each planting date and related to the average soil temperature. Soil temperature differences between the bare and mulch (2400 kg/ha wheat straw) fallow treatments were small. Slightly higher soil temperatures were recorded in the mulched plots but the differences had no significant effects on emergence and tillering. Average soil temperatures decreased gradually at each subjecent planting date but differences in the time interval between planting, emergence and tillering for the first four dates were slight. When considering the first four dates of planting the time interval between planting and emergence ranged from 9 to 11 days, while between emergence to tillering time interval ranged from 17 to 29 days. For the fifth and sixth planting date the interval between planting and emergence and emergence and tillering increased sharply ranging between 14 and 20 days and 51 and 125 days, respectively. These increases in time intervals between plant growth stages corresponded with relatively rapid decreases in average soil temperatures during the same period. Significantly lower grain yields were observed for the early (14 August) and late (1 November) planting dates when compared to the other four planting dates. The early planting date produced excessive vegetative growth and many tillers early in the season and may have used much of the stored moisture in the soil in the fall. There was also severe lodging in these plots. The first two planting dates also showed heavy infestation of barley yellow dwarf virus. The plants from the late planting lacked sufficient growth to efficiently use the moisture that was available. Within the second to fifth planting dates all four cultivars exhibited a differential response in yield and for some agronomic traits indicating distinctly different types of adaptation. Higher yields were noted for the barley cultivars, Hudson and Schuyler, at the second and third planting dates while the yield levels of the wheat cultivars, McDermid and Moro, were higher at the fourth and fifth planting dates. Differential responses in plants per square meter and tillers per plant at the same planting dates showed opposite trends, e., as the former increased the latter decreased. Neither of these two traits appeared to contribute to grain yield. The fallow treatments, bare and straw mulch had no significant effect on grain yield in the cultivars studied. However, a significantly higher 1000 kernel weight was observed with the straw mulch treatment. Number of plants per square meter was significantly higher under bare fallow than under mulch fallow treatment. All cultivars showed differential response to fallow systems in tillers per plant but not in yield and other agronomic traits. McDermid and Hudson responded to the mulch fallow while Moro had good response to the bare fallow in tillers per plant. Schuyler responded almost the same to the both mulch and bare systems in tillers per plant.
Download or read book Root Physiology from Gene to Function written by Hans Lambers and published by Springer Science & Business Media. This book was released on 2006-02-03 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the last decade, enormous progress has been made on the physiology of plant roots, including on a wide range of molecular aspects. Much of that progress has been captured in the chapters of this book. Breakthroughs have been made possible through integration of molecular and whole-plant aspects. The classical boundaries between physiology, biochemistry and molecular biology have vanished. There has been a strong focus on a limited number of model species, including Arabidopsis thaliana. That focus has allowed greater insight into the significance of specific genes for plant development and functioning. However, many species are very different from A. thaliana, in that they are mycorrhizal, develop a symbiosis with N2-fixing microsymbionts, or have other specialised root structures. Also, some have a much greater capacity to resist extreme environments, such as soil acidity, salinity, flooding or heavy-metal toxicities, due to specific adaptations. Research on species other than A. thaliana is therefore pivotal, to develop new knowledge in plant sciences in a comprehensive manner. This fundamental new knowledge can be the basis for important applications in, e.g., agriculture and plant conservation. Although significant progress has been made, much remains to be learnt. It is envisaged that discoveries made in the recent past will likely lead to major breakthroughs in the next decade.

This book was released on 2011-11-22 with total page 617 pages. Available in PDF, EPUB and Kindle. Book excerpt: Crops experience an assortment of environmental stresses which include abiotic viz., drought, water logging, salinity, extremes of temperature, high variability in radiation, subtle but perceptible changes in atmospheric gases and biotic viz., insects, birds, other pests, weeds, pathogens (viruses and other microbes). The ability to tolerate or adapt and overwinter by effectively countering these stresses is a very multifaceted phenomenon. In addition, the inability to do so which renders the crops susceptible is again the result of various exogenous and endogenous interactions in the ecosystem. Both biotic and abiotic stresses occur at various stages of plant development and frequently more than one stress concurrently affects the crop. Stresses result in both universal and definite effects on plant growth and development. One of the imposing tasks for the crop researchers globally is to distinguish and to diminish effects of these stress factors on the performance of crop plants, especially with respect to yield and quality of harvested products. This is of special significance in view of the impending climate change, with complex consequences for economically profitable and ecologically and environmentally sound global agriculture. The challenge at the hands of the crop scientist in such a scenario is to promote a competitive and multifunctional agriculture, leading to the production of highly nourishing, healthy and secure food and animal feed as well as raw materials for a wide variety of industrial applications. In order to successfully meet this challenge researchers have to understand the various aspects of these stresses in view of the current development from molecules to ecosystems. The book will focus on broad research areas in relation to these stresses which are in the forefront in contemporary crop stress research.

Download or read book Salinity Environment Plants Molecules written by André Läuchli and published by Springer Science & Business Media. This book was released on 2007-05-08 with total page 551 pages. Available in PDF, EPUB and Kindle. Book excerpt: In biology, the very big global and thevery small molecular issues currently appear to be in the limelight ofpublic interest and research funding policies. They are in danger of drifting apart from each other. They apply very coarse and very fine scaling, respectively, but coherence is lost when the various intermediate levels of different scales are neglected. Regarding SALINITY we are clearly dealing with a global problem, which due to progressing salinization of arable land is of vital interest for society. Explanations and basic understanding as well as solutions and remedies may finally lie at the molecular level. It is a general approach in science to look for understanding of any system under study at the next finer (or "lower") level of scaling. This in itself shows that we need a whole ladder of levels with increasingly finer steps from the global impact to the molecular bases of SALINITY relations. It is in this vein that the 22 chapters of this book aim at providing an integrated view of SALINITY.
