“…Previous studies focused mainly on differences in lodging-related traits in varieties (e.g. rice, maize, and wheat), including correlations between lodging resistance and plant height; length and diameter of basal internodes; weight of basal internodes; and starch, cellulose, or lignin contents, as well as those between cultivation conditions and yield or lodging resistance (Esechie et al, 2004;Mobasser et al, 2009;Tripathi et al, 2004;Xiang et al, 2010;Zuber et al, 1999). The risk of lodging increases at high planting density.…”

“…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 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).…”

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...

“…The increase in EPSM decreased TGW resulting in nonsignificant effects of PGRs on GY. Although higher Nlevel increases GY (Pietola et al, 1999), severe lodging can significantly reduce yield in susceptible varieties (Tripathi et al, 2004). The results obtained from Trial 3 revealed that GY between the PGR treated plots and the control was not different.…”
