“…Our correlation analysis indicated the enzyme activities of PAL, 4CL and CAD were significantly and positively correlated with the lignin content of culm in buckwheat. Peng et al (2014) concluded that the lignin content was significantly correlated with the enzyme activities of PAL, TAL and POD in wheat culms. However, concluded that the lignin content was significantly and positively correlated with the enzyme activities of PAL, TAL and CAD, but not with 4CL activity in the wheat culm.…”

“…Lodging caused a 14.3% loss in rice production in coastal regions of Jiangsu China (Zhang et al, 1996) and 8.3% loss of grain yield in spring wheat (Tripathi et al, 2004). Lodging is reported to be one of the limiting factors of buckwheat production in Nepal (Baniya, 1990).Lignin, which is a major structural component of secondary cell walls in vascular plants, is not only associated with plant growth and development, but also provides the plant body with mechanical strength (Peng et al, 2014). Lignin plays an important role in improving the strength of plant cell walls and increasing the mechanical intensity of culm (Lewis and Yamamoto, 1990;Turner and Somerville, 1997).…”

Lodging is an important constraint limiting buckwheat yield and quality by bending or breaking culm on buckwheat production worldwide. This study was conducted with Ningqiao 01, a moderate lodging resistance cultivar of buckwheat, to determine whether lignin synthesis and lodging resistance of buckwheat are affected by nitrogen fertilizer and planting density. The results showed that the lignin content at the bottom of the 2nd internode was significantly and negatively correlated with lodging index and lodging percentage, but significantly and positively correlated with snapping resistance. The snapping resistance rose and then fell with the increase of nitrogen fertilizer. The snapping resistance decreased with the increase of planting density. The lodging index increased with the increase of nitrogen fertilizer and planting density. The lignin content and its related enzymes activities decreased with the increase of nitrogen fertilizer and planting density. These results suggested that the lignin content is closely related to the lodging resistance of buckwheat, and a higher lignin content could strengthen the lodging resistance of buckwheat. The increase of nitrogen fertilizer and planting density significantly increased the risk of lodging by decreasing the lignin content and its related enzymes activities at the bottom of the 2nd internode.Key words: Buckwheat, Lignin, Lodging, Nitrogen fertilizer, Planting density.Buckwheat (Fagopyrum esculentum), which belongs to the family Polygonaceae, genus Fagopyrum, is commonlyconsumed in arid and cold regions in the world (Koyama et al., 2013). Buckwheat species native to China have been systematically classified since 1913 and it has been praised as one of the most faddish green function in the 21st century (Guo et al., 2007). Buckwheat grains are an important source of macroelements such as K, Ca, Mg, and Na as well as microelements such as Mn, Zn, Se, and Cu (Wei et al., 2003), and they contain rutin, riboflavin, pyridoxine, thiamine, lysine, methionine, arginine, and threonine (Fabjan et al., 2003). The starch of buckwheat includes numerous compounds that have been identified to have beneficial effects on human health, including lowering both blood lipid and sugar levels (MendlerDrienyovszki et al., 2013).Lodging, the permanent displacement of stems from an upright position due to internal and external factors (Pinthus, 1973), is an important constraint limiting crop yields and quality (Crook and Ennos, 1994). Severe lodging destroys plant morphology, resulting in the reduction of photosynthetic ability, grain yield, grain filling, and harvesting efficiency (Berry and Spink, 2012). Enhancing the physical strength of the culm is important for lodging resistance. In spite of the vast research performed to reduce lodging in major cereal crops, such as wheat and rice, lodging is still a dominant contributor to yield reduction (Athwal, 1971;Murakami et al., 2012). Lodging caused a 14.3% loss in rice production in coastal regions of Jiangsu China (Zhang et a...

“…In this study, N supply can significantly increase the rind thickness, Vbs thickness and number of Vb of both cultivars, while no significant differences were observed between N120 and N180 at D1. Peng et al (2014) pointed out that optimal N rate can significantly increase the content of lignin synthesis and the density of Vb, which can improve the stalk lodging resistance.…”

“…At high density, however, plants may compete for light and soil resources available (e.g., water and nutrients; Tollenaar et al 2006), which results in thinner stems that increase the risk of lodging. Nitrogen supply can enhance the lodging resistance by increasing the activity of the key enzymes regulating the lignin biosynthesis, the content of lignin and stalk diameter (Peng et al 2014). Studies in the past decades focused primarily on the effects and reasons of stalk lodging and selection of stalk lodging indicators, but little attention was given to the stalk mechanical performance and microstructure of different density-tolerant cultivars at high plant density.…”

Stalk lodging is a major constraint to limit grain yield under increased planting density in modern maize (Zea mays L.) production. A 3-year field experiment was imposed to study the effects of plant density and nitrogen (N) rate on stalk lodging and lodging-related stalk traits of two maize hybrids of contrasting susceptibility to lodging. The results indicated that the stem diameter, rind penetration strength (RPS), bending strength (BS), rind thickness, vascular bundle sheath's thickness (Vbs) and number of vascular bundle (Vb) of both hybrids all significantly decreased at the high density, while ear height and ear ratio clearly increased in Ludan981 (LD981; lodging-susceptible cultivar) with plant density increase. The lower plant height and ear height, stronger RPS and BS, and more Vb at high plant density might be reasons for Zhengdan958 (ZD958, lodging-resistant cultivar) had lower rate of stalk lodging. Meanwhile, N supply can significantly improve the stalk quality and decrease the risk of stalk lodging, however, little effects were observed in cv. LD981. Therefore, using lodging-resistant cultivar, planting at 82 500 plant/ha and supplying 180 kg N/ha can obtain high grain yield and low stalk lodging.Keywords: maize lodging; lodging resistance; mechanical property; microstructure 299Plant Soil Environ. Vol. 62, 2016, No. 7: 299-306 24.55, 26.35, and 25.42°C and 247.7, 225.4, 236.1 mm in 2013, 2014 and 2015. For this study, Zhengdan958 (ZD958, lodgingresistant cultivar) and Ludan981 (LD981, lodgingsusceptible cultivar), were used for experimental materials. Two plant densities (D1 -52 500, D2 -82 500 plants/ha), and three N rates (N0 -0, N120 -120, N180 -180 kg N/ha as urea) were conducted for the two cultivars. The experiments were established in a split-plot design of three replicates (36 subplots), with cultivar as the main plot, with density and nitrogen rate as the sub-plot. These subplots were arranged randomly and the size of each subplot was 15.0 m × 3.0 m (rows spaced 60 cm apart).Basal fertilization of each subplot was applied before tillage during both years; it included phosphorus as calcium superphosphate and potassium as chloride at the rate of 53 kg P/ha and 119 kg K/ha, respectively. The N fertilizer source was half applied at the sixth leaf stage (V6) and half at the twelfth leaf stage (V12). The seeds were sown on 17 June and harvested on 5 October in each test year. Water, weeds, insects, and diseases were controlled as required to avoid yield loss.Grain yield. In this experiment, thirty successive ears were hand harvested from the centre rows of each plot at physiological maturity (R6). Grains of all harvested ears were separated manually from cobs and weighed to determine the average individual yield. The grain yield per hectare was the product of ear density and average individual yield.Stalk lodging estimates. All plants that bent and broke in the central three rows of each plot were counted to calculate stalk lodging at R6. Stalk lodging was the ratio of the num...

Ridge-furrow with plastic film mulching (RFPFM) is widely used as a water-saving strategy for the improvement of crop yield. However, lodging susceptibility under RFPFM practices has not yet been determined. A 2-yr field study comprising of three cultivation strategies (rain-fed flat planting [FP], RFPFM, and well-water planting [WW]) and two N application rates (75 and 225 kg N ha -1 ) was conducted to assess the risk of lodging and the relationship between lodging resistance and grain yields of two wheat (Triticum aestivum L.) varieties (Xinong979 as lodging resistant and Xiaoyan22 as lodging susceptible). The results showed that higher N application increased lodging index under FP and RFPFM, and the lodging index was 33% lower under RFPFM than under WW. In both years, there was a positive relationship between grain yield and lodging susceptibility (R 2 = 0.62** and 0.57**) implying that promoting crop yield by using RFPFM strategy accelerates the risk of lodging. When compared with WW, RFPFM significantly reduced the lodging index, while sustaining a comparable grain yield. Overall, RFPFM could be highly recommended as a promising strategy for winter wheat producers in dry, semi-humid regions. The close relationships of breaking resistance and lodging index with both mass density and stem wall thickness of basal internode suggest that selection for increased stem strength trait could lead to improved lodging resistance and higher yields in future programs for winter wheat cultivar improvement.Abbreviations: BM, bending moment; DAS, days after sowing; FP, rain-fed flat planting; LAI, leaf area index RFPFM, ridge-furrow with plastic film mulching; WW, well-water planting.
