to study the effect of plant density and planting pattern on iranian ox-tongue, an experiment carried out with two factors: planting pattern (square and rectangular pattern) and plant density (2, 4, 6, 8 plant m-2) in a factorial test performed based on rcbd in 3 replications during 2009-2010 in latmahalleh eshkevarat village in guilan province, iran. characteristics that measured included: dry...

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...

introduction lentil (lens culinaris medic) is a member of the leguminosae (fabaceae) family and an important pulse crop grown in iran. growth of lentil plant is highly sensitive to environmental conditions, especially solar radiation, high temperature and water availability. one of the important reasons for unstable lentil yield is the indeterminate growth habit of lentil plants. extensive vege...

pot marigold (calendula officinalis l.) is a medicinal and ornamental plant. the effect of different concentrations of chlormequat (cycocel), and daminozide, two plant growth retardant, on plant height, flowering, the content of essence and some other traits in pot marigold (calendula officinalis) was assessed. plant growth retardants are commonly applied to limit stem elongation and produce a ...

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...

Triticale (xTriticosecale Wittmack) is an important feed crop which suffers severe yield, grade and end-use quality losses due to Fusarium head blight (FHB). Development of resistant triticale cultivars is hindered by lack of effective genetic resistance sources. To dissect FHB resistance, a doubled haploid spring triticale population produced from the cross TMP16315/AC Ultima using a microspor...

in order to locate the qtls for plant height, peduncle length, and heading date, a set of 107 wheat doubled haploid (dh) lines derived from the cross fukuho-komugi× oligoculm was grown during the growing seasons of 2004 and 2005. a total of 36 qtls were identified based on composite interval mapping (cim) approach. all detected plant height qtl’s were stable over the two years. qtls located nea...

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...

Abstract Increasing soybean yield plays a key role in meeting the high demand for protein Europe and other countries. The aim of this study was to dissect genetic architecture underlying seed yield, plant height, thousand‐seed weight early‐maturing soybean. To end, we performed QTL mapping based on 944 RILs derived from half‐diallel crossing design five parents. We identified eight each four ag...
