“…It is believed that the reduced length of the culm, in combination with the increase in the crop and cultivar flexibility, ensures high resistance to lodging in intensive production. Introduction of chemical growth-retardants to agricultural practices effectively limited culm length, which, in turn, improved the resistance of the crop to lodging (Berry et al, 2004;Tripathi et al, 2003). Olumekun (1996) reported that the Cycocel growth retardant (i.e.…”

A b s t r a c t. Cereal straw is an important biomass source inEurope. This work assessed: 1) the morphological and energetic characteristics of culms of spring and winter cereals, 2) the energy deposited in the different aboveground parts of cereals, 3) losses of energy due to different cutting heights. The straw of winter and spring cereals was collected from arable fields during the seasons 2009/10 and 2010/11 in southern Poland. Detailed biometric measurements of culms and internodes were performed. The losses of straw biomass and energy were assessed during simulation of cutting the culm at different heights, up to 50 cm. Longer and heavier culms were developed by winter wheat and triticale and oat. Cutting of straw up to 10 cm did not lead to significant losses in straw yield. The total amount of energy in the culms was as follows: triticale > winter wheat > oat > spring wheat > winter barley > spring barley. Cutting the culms above 20 cm led to significant differences in terms of biomass energy between cereal species. The smallest losses of energy were recorded for spring and winter barley. Oat and barley accumulated the highest energy in grains.

“…No que diz respeito ao genótipo, os conteúdos de celulose, hemicelulose e lignina, especialmente em nós e entrenós basais, assim como a altura da planta, são caracteres fortemente associados à resistência ou à suscetibilidade ao acamamento (Tripathi et al, 2003;Zhu et al, 2004).…”

O objetivo deste trabalho foi avaliar os efeitos da aplicação de concentrações do regulador de crescimento etil-trinexapac na altura de planta, no acamamento e na produtividade de grãos da cultivar de aveia-branca Barbarasul, em diferentes ambientes de cultivo e doses de nitrogênio. Os experimentos foram conduzidos nas safras 2010 e 2011 nos municípios de Capão do Leão e Augusto Pestana, no Estado do Rio Grande do Sul, e nas safras 2010 e 2012 no Município de Lages, no Estado de Santa Catarina. Utilizou-se o delineamento de blocos ao acaso, em arranjo fatorial 4x2x6 (dose de etil-trinexapac, estádio de desenvolvimento da planta e ambiente), com quatro repetições constituídas por parcelas úteis de 3,0 m2. Em cada ambiente, realizou-se adubação nitrogenada com 30 e 90 kg ha-1 de N. Foram avaliados os caracteres altura de planta, percentagem de acamamento e produtividade de grãos. A aplicação do regulador de crescimento etil-trinexapac nas doses de 100 a 150 g i.a. ha-1 em plantas de aveia-branca 'Barbarasul', nos estádios E31 e E32, reduz a altura das plantas e a percentagem de acamamento, sem prejuízos à produtividade de grãos. A intensidade da redução do acamamento depende das características do ambiente de cultivo.

“…This outcome suggested that the mechanism by which PGR increased resistance to lodging may not be related to StL alone. Other lodging related stem traits such as SD (Easson et al, 1993), SWCM (Zuber et al, 1999) as well as EW (Tripathi et al, 2003) were investigated in Trial 2. It has been reported that a higher SD is an indication of lodging resistance (Mukherjee et al, 1967) but the Trial 2 results showed no evidence that PGRs affected SD.…”

“…However, farmers are concerned about Bere's susceptibility to lodging due to its long and weak straw (Martin et al, 2010). Severe lodging can interfere with the speed and efficiency of harvesting operations (Tripathi et al, 2003) and, most importantly, it can cause significant economic losses by reducing grain yield (GY) (Pinthus, 1973) and grain quality of barley (Stanca et al, 1979;Birggs, 1990). In order to avoid lodging related negative effects on harvesting and grain yield, Bere is presently grown with no or low nitrogen inputs (30 kg N ha -1 ) on marginal land in Orkney (Dr. Peter Martin, personal comm.).…”

“…In order to avoid lodging related negative effects on harvesting and grain yield, Bere is presently grown with no or low nitrogen inputs (30 kg N ha -1 ) on marginal land in Orkney (Dr. Peter Martin, personal comm.). Plant growth regulator (PGR) can reduce stem length and improve the standing ability of the barley (Kust, 1985;Sanvicente et al, 1999) and wheat (Jung, 1964;Tripathi et al, 2003). Amongst PGRs Ethephon (2-chloroethyl phosphonic acid) (ET) and Chlormequat chloride (CCC) have been effective in decreasing plant height and reducing lodging incidence in wheat (Crook and Ennos 1995).…”
