Seed vigor testing: An overview of the past, present and future perspective. Find support for a specific problem on the support section of our website. Thus, this study aimed to evaluate the production and physiological quality of ryegrass seeds, in response to the application of herbicides and plant growth regulators, in three reproductive stages of the plant. ; Ferrari, L.; Rondanini, D.P.

[, The herbicide clethodim drastically decreased the vigor (36%) (first germination count) of wheat seeds when applied in the grain filling stage [, Herbicides may have caused a decrease in seed reserves and, consequently, vigor. Lolium multiflorum Italian ryegrass provides excellent quality forage for up to two years, depending on climate and available moisture. Lolium rigidum is Australia’s leading winter crop weed [27], recognized for the rapid evolution of herbicide resistance [28] and for developing multiple resistance (seven mechanisms of action) [29]. Tel: +31 24 348 81 00. Damage to the inflorescence reduces the formation of seeds and interrupts the development of the growing embryo, decreasing viability [, The viability of ryegrass seeds at the fruit development stage was also increased in comparison to untreated control (, Similar results of herbicidal effect on the physiological quality of ryegrass seeds were found by Campos et al. is the main winter weed of crops in Southern Brazil. Bewley, J.D. ; Freitas, F.C.L. Lolium multiflorum. ; Pimentel, L.D. })(window,document,'script','//www.google-analytics.com/analytics.js','ga'); Italian ryegrass, also called annual ryegrass, is an upright annual grass that behaves like a biennial or short-lived perennial.

Lolium temulentum: glume mostly 7–28 mm long, the body 0.75–1.5 times as tall as the column of florets, plants annual, with 2- to 10-flowered (vs. L. multiflorum, with the glume 3.5–15 mm long, the body 0.25–0.75 times as tall as the column of florets, and plants annual or perennial, with mostly 5- to 22-flowered spikelets). When does it make sense to target the weed seed bank? Effects of 2,4-D on Seed Production and Embryo Development of Curly Dock. That is, we receive commissions for purchases made through various links on this website. Our dedicated information section provides allows you to learn more about MDPI. ; Gbur, E.E. How can we target the weed seedbank? Furthermore, the impact of applications of these products on spikes, flowers and fruits (caryopsis) on the production and physiological quality of ryegrass seeds has been little studied. Marcos Filho, J. Lolium perenne var. Ryegrass (Lolium multiflorum Lam.) Habit. Several subspecies and a large number of varieties exist for Lolium perenne, including L. perenne subsp. It is the only grass to produce a stem and seed head from a spring sowing making it suitable for the production of hay for horses. The highest mortality of ryegrass seeds (53%) occurred with the application of ammonium glufosinate (400 g ha, In the subsequent paragraphs the practical aspects of the study are commented and discussed.
