“…Furthermore, the stems were easier to be located and observed because they were not covered compared with the roots and had a smaller number compared with the leaves. However, the current research on stem strength was mainly used to investigate the lodging resistance characteristics of crops (Li et al, 2021d;Manga-Robles et al, 2021;Sekhon et al, 2020;Shao et al, 2021;Xue et al, 2017), which was extremely surprising and regrettable. Hence, as the only channel acid reaction described by Pi, z. et al (Pi et al, 2014).…”

In order to investigate the effects of N and K on the mechanical properties of cucumber stems, the physiological and biochemical indexes under different N and K conditions were compared. The analysis showed that the pho-tosynthetic rate was affected by both stress and the self-senescence of cucumber plants, and that the crops under N and K stress were stimulated to activate a highly effective antioxidant system to cope with the damage. Sugar, as the basis for the synthesis and structure formation of the stems, was highly related to stem strength, and polyphenol oxidase in the study of stem strength was limited but indispensable. Compared with CK, the epidermal penetration strength under LN, LNLK, and LNHK treatments increased by at least 10%, while the strength under HN, LK, HNLK, and HNHK treatments decreased by at least 7%. To sum up, it was the photosynthesis rate, the sucrose transportation, as well as the futile cycling of K+ that were the keys of stem strength.

“…Lodging can seriously affect the health of maize, leading to a decline in the resistance to diseases and pests of maize, and lodging can also adversely affect mechanized harvesting [4,5]. Lodging is a major agricultural problem that affects grain crop production [6]. Lodging occurs in different growth stages and severity, leading to varying degrees of maize yield reduction and even failure [7].…”

Lodging is one of the main problems in maize production. Assessing the self-recovery ability of maize plants after lodging at different growth stages is of great significance for yield loss assessment and agricultural insurance claims. The objective of this study was to quantitatively analyse the effects of different growth stages and lodging severity on the self-recovery ability of maize plants using UAV-LiDAR data. The multi-temporal point cloud data obtained by the RIEGL VUX-1 laser scanner were used to construct the canopy height model of the lodging maize. Then the estimated canopy heights of the maize at different growth stages and lodging severity were obtained. The measured values were used to verify the accuracy of the canopy height estimation and to invert the corresponding lodging angle. After verifying the accuracy of the canopy height, the accuracy parameter of the tasselling stage was R2 = 0.9824, root mean square error (RMSE) = 0.0613 m, and nRMSE = 3.745%. That of the filling stage was R2 = 0.9470, RMSE = 0.1294 m, and nRMSE = 9.889%, which showed that the UAV-LiDAR could accurately estimate the height of the maize canopy. By comparing the yield, canopy height, and lodging angle of maize, it was found that the self-recovery ability of maize at the tasselling stage was stronger than that at the filling stage, but the yield reduction rate was 14.16~26.37% higher than that at the filling stage. The more serious the damage of the lodging is to the roots and support structure of the maize plant, the weaker is the self-recovery ability. Therefore, the self-recovery ability of the stem tilt was the strongest, while that of root lodging and root stem folding was the weakest. The results showed that the UAV-LiDAR could effectively assess the self-recovery ability of maize after lodging.

“…Increases in rind puncture resistance and formation of the cortex tissue have been closely related with cellulose and lignin deposition, serving as structural support to the cell wall 32 . Moreover, cellulose compositional features, such as crystallinity, have been related to stalk lodging and stalk strength, which could be associated with rind puncture resistance, as previously mentioned 15 . It has been also…”

Maize stalks support leaves and reproductive structures, functionally support water and nutrient transport; besides their anatomical and biochemical characteristics have been described as a plant defense against stress, also impacting economically important applications. In this study, we evaluated agronomical and stem description traits in a subset of maize inbred lines that showed variability for cell wall composition in the internodes. Overall, a great proportion of lignin subunit G and a low concentration of pcoumaric acid and lignin subunit S is beneficial for greater rind puncture resistance and taller plants, with greater biomass yield. Also, the greater the proportions of subunit H, the longest the internode. By last, the lower the total hemicellulose content the greater the rind puncture resistance. Our results confirmed the effect of the cell wall on agronomic and stalk traits which would be useful in applied breeding programs focused on biomass yield improvement.
