Book Synopsis Salinity Tolerance of Greens-Type Poa Annua L by : Jing Dai
Download or read book Salinity Tolerance of Greens-Type Poa Annua L written by Jing Dai and published by LAP Lambert Academic Publishing. This book was released on 2011-05 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: Greens-type Poa annua L. (annual bluegrass) is being developed into a commercial turfgrass. The salinity tolerance of greens-type Poa annua was studied to improve general understanding and accelerate the breeding process. Literature indicates that Poa annua does not contain salinity tolerance; empirical observations, however, suggest greens- types Poa annua may possess more tolerance to saline environments. As research data were very limited on the salt tolerence of greens-type Poa annua, comparisons were conducted among Poa annua biotypes, greens-type Poa annua experimental lines, and common cool-season turgrass species during seed germination and vegetative growth for comprehensive intra- and inter-species evaluations. The studies suggest that greens-type Poa annua has evolved moderate to good salinity tolerance and should be distinguished from the weedy type Poa annua in terms of salinity tolerance.

This book was released on 2014 with total page 101 pages. Available in PDF, EPUB and Kindle. Book excerpt: Annual bluegrass (Poa annua L.) is a problematic weed species found in many turfgrass stands, particularly golf course putting greens. This weed is light green in color, has poor heat and drought tolerance, and produces many seeds making it undesirable on putting greens. The objectives of this research were to: a) investigate the use of the herbicide bispyribac-sodium alone or in combination with plant growth regulators for annual bluegrass control and putting green tolerance; b) determine the efficacy of plant growth regulators on annual bluegrass seedhead suppression when applied once, or followed by a sequential application; and c) determine how chemicals applied at different growth stages of annual bluegrass effect shoot growth and seedhead development. Field and greenhouse research was conducted during 2010, 2011, 2012 and 2013 at multiple golf courses throughout central Missouri. Treatments of bispyribacsodium alone or in combination with paclobutrazol demonstrated safety to putting greens with high levels of annual bluegrass control (90%). For seedhead suppression, treatments containing ethephon were most effective, resulting in up to 95% suppression of seedheads. Regardless of plant stage during application, annual bluegrass biomass was reduced 19 and 31% following applications of ethephon + trinexapac-ethyl or paclobutrazol, respectively.

Book Synopsis Annual Bluegrass (Poa Annua L.) Emergence Under Different Residue Management Practices in Perennial Ryegrass and Determination of Resistant and Susceptible Annual Bluegrass Germination Under Controlled Temperature and Moisture by : Matthew D. Schuster
Download or read book Annual Bluegrass (Poa Annua L.) Emergence Under Different Residue Management Practices in Perennial Ryegrass and Determination of Resistant and Susceptible Annual Bluegrass Germination Under Controlled Temperature and Moisture written by Matthew D. Schuster and published by . This book was released on 1999 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the loss of field burning the amount of crop residue that remains in perennial ryegrass fields has increased. As the amount of crop residue remaining in the field increases so does annual bluegrass. This has resulted in the increased use of herbicides to control annual bluegrass. However, this increased use has also resulted in herbicide-resistant annual bluegrass. Field experiments were initiated in 1997 to investigate residue management options available to growers and their impacts on annual bluegrass emergence. Two sites, Glaser and Wirth, were established with three residue management treatments replicated four times. The treatments included full-straw, bale/flail, and vacuum sweep. Perennial ryegrass seed yield and annual bluegrass seed contamination were evaluated. The vacuum sweep treatment had lower annual bluegrass emergence than the full-straw or the bale/flail treatments during the 1997-98 growing season, for both sites. The fall of 1998 was much drier than the fall of 1997. Annual bluegrass emergence in all plots was lower in 1998 than in 1997 because of the dry conditions. Fall emergence in 1998 was higher in the vacuum sweep treatment than in the other two treatments, which may have been the result of better soil-seed contact in the vacuum sweep treatment. Lower emergence in the spring at the Wirth site compared to the Glaser site may have been due to narrow crop row spacing and cultivar selection, which shaded the annual bluegrass. When growing seasons were combined, there were no treatment differences. However, more emergence was observed in the spring at the Glaser site compared to the Wirth site. Yield was highest for the vacuum sweep treatment at the Glaser site in the 1998-99 growing season. However, competition from volunteer perennial ryegrass in the full-straw and bale/flail treatments could have accounted for this increase. No other differences in yield and no difference in contamination among treatments were observed. However, contamination at the Glaser site was higher in the 1998-99 growing season than in the 1997-98 growing season. Experiments were conducted in growth chambers to determine how differing environmental conditions affect seed germination of diuron-susceptible and diuron-resistant annual bluegrass. Cumulative germination for the susceptible-biotype decreased from 96% to 88% while the resistant-biotype remained above 95% as temperature decreased from 3 0/20 C to 10/2 C. The susceptible-biotype germinated sooner than the resistant-biotype regardless of temperature. The susceptible-biotype had a higher rate of germination than the resistant-biotype at 30/20 C, but not when the temperature decreased to 10/2 C. Germination response to differing matric potentials did not vary much within a biotype for a given soil type and temperature. Therefore, parameters estimated at -1.03 MPa were chosen to contrast susceptible- and resistant biotypes, and soil types, for each temperature. Maximum cumulative germination was greater than 96% for all treatments. When germination on a given soil type was contrasted, differences were only seen for the susceptible biotype vs. resistant biotype on Dayton soil; and the resistant biotype on Dayton soil vs. resistant biotype on Woodburn soil at both temperatures. The lag in onset of germination was shorter for the susceptible biotype on Dayton soil and resistant biotype on Woodburn soil than the resistant biotype on Dayton soil at 30/20 C. At 18/5 C, the lag in onset of germination was shorter for the susceptible biotype on Dayton soil and resistant biotype on Woodburn soil than the resistant biotype on Dayton soil (P = 0.000 1 and 0.0001, respectively). But the rate of germination was faster for the resistant biotype on Dayton soil than both the susceptible biotype on Dayton soil and resistant biotype on Woodburn soil at 18/5 C (P = 0.02 and 0.0004, respectively). The rate of germination did not differ at 3 0/20 C. When just the soils were contrasted, at 18/5 C all annual bluegrass seeds on the Woodburn soil germinated sooner and the rate of germination was higher than on the Dayton soil. These results indicate that the hydraulic properties of the soils may influence germination. However, this was not observed at 30/20 C. The results suggest that the susceptible-biotype was more sensitive to temperature while the resistant-biotype was more sensitive to moisture. Changing crop management in ways that will reduce annual bluegrass emergence and establishment is needed. By altering management strategies, growers may obtain more efficient and effective use of herbicides, while reducing the selection of herbicide-resistant annual bluegrass.

Book Synopsis Stress and Stress Coping in Cultivated Plants by : B.D. McKersie
Download or read book Stress and Stress Coping in Cultivated Plants written by B.D. McKersie and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two experienced and well-known research scientists, each from a vastly different part of the world, have combined their respective expertises to provide the reader with perhaps a unique text which presents an in-depth treatment of the various stress manifestations and an overall discussion of stress in cultivated plants. Professor Bryan McKersie of Canada, who over the years has been active in research, teaching and agricultural application of scientific techniques, has dealt with and described cold, chilling, flooding, desiccation and oxidative stress phenomena: Professor Ya'acov Leshem of Israel, whose research experience and activities have centered around different facets of plant stress, has covered heat, drought, salinity and environmental pollution. Notwithstanding their different research experiences, both authors have cooperated and together have written a well-integrated and up-to-date text describing the major stress factors and problems which are limiting factors for optimal plant growth and hence of yield. The information assembled carefully in this book makes no claim to provide ready-made remedies to overcome the various stresses but in many cases suggests feasible and scientifically applicable approaches and partial solutions for stress coping, some of which are now in the process of being developed. This book is intended for research workers and students of agriculture and horticulture, for plant physiologists and is of overall interest to scientists dealing with stress physiology.
