Winter wheat, (cv. Consort) was inoculated with three isolates of either Oculimacula yallundae or O. acuformis to determine the effect of eyespot caused by each species on yield and lodging resistance of winter wheat. Plants were visually assessed for disease incidence and severity, and pathogen DNA was quantified at GS 33 and GS 60. At early milk development of the crop (GS 72), 900 main shoot...

The distant hybridization was used in lodging-resistance breeding of Platycodon grandiflorus. The parents were Platycodon grandiflorus (♀) and Campanula medium (♂). 187 seeds of F1 were harvested by using the inter-generic hybridization in 2009 and 2010, 2 repeat, and 88 normal plants were obtained. The characteristics of leaves, stems and branches were the same as female for F1 generation, F2 ...

The objectives of this study were to explore the mechanism by which the lodging resistance of the rice population during the late growth period responds to low-temperature, overcast and rainy weather during the reproductive growth stage. Field experiments were conducted using indica rice Yliangyou2 (lodging-resistance variety), IIyou084 (lodging-susceptible variety) and japonica rice Wuyunjing2...

For improving lodging resistance and increasing grain yield in wheat the Yellow-Huai River Basin China, different sowing modes have been investigated. Conventionally, small-flat-plot mode has adopted cultivation. However, this leads to heavy low land use efficiency. In study, a new mode, high-low-plot with two more rows sowed on high plot, was Two cultivars, Hengguan 35 Jimai 44 were used for s...

Gladiolus (Gladiolus grandiflorus L.), a popular bulbous cut flower, has high demand in both domestic (Pakistani) as well as international markets. Five potential, exotic cultivars of gladiolus, ‘Cantate’, ‘Corveira’, ‘Eminence’, ‘Essential’ and ‘Fado’ were evaluated to determine the cultivar effects on yield and quality, to compare their relative performance and recommend their suitability for...

The natural occurrence of lodging in wheat (Triticum aestivum L.) small-plot research aiming to record visual ratings is unpredictable highly dependent on environmental conditions, and does not differentiate between root shoot lodging. Detailed plant characteristics can be used indicate risk; however, such measurements are destructive time-consuming for projects that focused solely evaluating S...

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...

twenty five durum wheat lines were evaluated under drought stress and non-stress conditions employing randomized complete block design of 4 replications. significant differences were observed among the lines for most traits in either stress or non-stress conditions. correlation analysis under non-stress conditions indicated that grains per spike and number of spikes per m2 and while under stres...
