Lodging is one of the constraints that limit wheat yields and quality due to the unexpected bending or breaking stems on wheat (Triticum aestivum L.) production worldwide. In addition to choosing lodging resistance varieties, husbandry practices also have a significant effect on lodging. Nitrogen management is one of the most common and efficient methods. A field experiment with Yangmai 20 as r...
Dry direct-seeded rice (DSR) is an alternative crop establishment method with less water and labor requirement through mechanization. It provides better opportunities for a second crop during the cropping season and therefore, a feasible alternative system to transplanted lowland rice. However, lodging is one of the major constraints in attaining high yield in DSR. Identification of QTLs for lo...
Introduction In connection with a study of the cause of lodging in soybeans as grown in corn for silage it was found that the shading by the corn resulted in a reduction of the percentage of carbohydrates and total dry matter, and that the stems of soybeans thus developed were relatively soft, pliable, and weak. In cereals like oats and wheat a similar situation in the stems with consequent lod...
BACKGROUND Biomass recalcitrance and plant lodging are two complex traits that tightly associate with plant cell wall structure and features. Although genetic modification of plant cell walls can potentially reduce recalcitrance for enhancing biomass saccharification, it remains a challenge to maintain a normal growth with enhanced biomass yield and lodging resistance in transgenic plants. Sucr...
Stem lodging-resistance is an important phenotype in crop production. In the present study, the expression of the wheat COMT gene (TaCM) was determined in basal second internodes of lodging-resistant (H4564) and lodging-susceptible (C6001) cultivars at stem elongation, heading, and milky endosperm corresponding to Zadoks stages Z37, Z60, and Z75, respectively. The TaCM protein levels were analy...
Excerpt] In the last two decades of the twentieth century the lodging industry experienced an unprecedented level of consolidation. In particular, mergers and acquisitions among lodging companies took place at record levels in the late 1990s. From 1982 through 2000 the industry saw a total of 57 acquisitions with an aggregate market value in the target companies’ stocks of over $53 billion doll...
In order to evaluate the effect of seed priming on lodging-related characteristics in direct seeding method, a study was conducted in a factorial randomized complete block design with four replicates in the research field of Rice Research Institute of Iran (Rasht) for two years. The first factor consisted of two rice cultivars (Khazar and Hashemi) and the second one consisted of ten levels of s...
Yield and lodging related traits are essential for improving rapeseed production. The objective of the present study was to investigate the influence of plant density (D) and nitrogen (N) rates on morphological and physiological traits related to yield and lodging in rapeseed. We evaluated Huayouza 9 for two consecutive growing seasons (2014-2016) under three plant densities (LD, 10 plants m-2;...
In order to evaluate the morphological characteristics and lodging-related traits and comparison of improved cultivars of rice plant resistance to lodging, a field experiment was carried out in randomized complete block design with three replications in 2012 at the Rice Research Institute of Iran )Rasht(. Rice cultivars were Kadus, Khazar, Gohar, Dorfak, Sepidrood and Deylam and local rice cult...
The use of fertilizer results in tall rice plants that are susceptible to lodging and results in reduced plant yields. In this study, using chromosome segment substitution lines, we identified an effective quantitative trait loci (QTL) for culm strength, which was designated STRONG CULM2 (SCM2). Positional cloning of the gene revealed that SCM2 was identical to ABERRANT PANICLE ORGANIZATION1 (A...
