“…Due to this property, lignin is sometimes referred to as a “cellular glue” . Whole stem lignification has been highly correlated with lodging resistance, − where the reduction in lignin concentrations often results in increased lodging. , Large variations in stem lignin content in plants, even within the same species, have been reported. , Not only does lignin content differ among plants, its composition in different plant tissues varies significantly. For example, plant xylem cells are reported to have higher lignin content compared to thick fiber cells .…”

Understanding the contribution of stem cell wall components to lodging is important in developing breeding programs aimed at reducing lodging in cereal crops. This study is one of the first to investigate the correlation between the amounts of cell wall-bound ferulic acid, p-coumaric acid, and lignin in the nodes and internodes of cereals (oat, wheat, and barley) and their lodging susceptibility during grain fill. All samples, except two-row barley, were susceptible to lodging and expressed a significantly lower stalk strength. Lignin and phenolic contents between nodes and internodes of all samples were significantly different, with internodes having higher amounts (5.5–7.0 and 10.9–16.2 μg/g p-coumaric acid, and 2.5–3.2 and 3.9–7.1 μg/g ferulic acid in nodes and internodes, respectively). The acid-soluble lignin content was different between nodes and internodes but not between crops. This data set did not correlate with lodging classification, possibly due to sample size and type.

Synopsis Lodging of small grains due to environmental stresses results in yield loss, quality reduction, and difficulties with mechanical harvesting, which lead to economic consequences. New technological discoveries allow for faster and in situ measurements for determining the mechanics of loading stress and plant movement. The overall measurement of plant movement can be a very sophisticated method to mechanically test and predict the behavior of stems when exposed to wind. We investigated the inertial measurement of plants during different magnitude wind events. This type of analysis captures real time quantitative stem behavior during wind events. Using a 1.5 cm2 inertial measurement sensor attached to the upper panicle of a plant, we recorded the ranges and extremes of instantaneous linear acceleration and rotational velocity. When this technology was applied to historically known varieties of different lodging classification, the measurements were able to distinguish between cereal species and differences between movement of lodging susceptible and resistant plants without physical lodging. This type of technology could be used to improve field based lodging models and quantify movement resulting from micro changes in structural and composition of the stem, and to analyze plant movement in natural conditions with a resolution and specificity that has so far been prohibitively expensive and technologically challenging to achieve.
