Drought stress is the most important limiting factor in crop plants including maize (Zea mays L.), which is the third important world crop after wheat and rice. Water deficiency at different growth stages affects maize yield differently. To examine the response of four maize hybrids to drought stress at different growth stages, a field experiment was carried out as a split plot based on complet...
BACKGROUND The purpose of this study was to assess the impact of bone harvest length and multiple osteotomies on osteocutaneous radial forearm free flap (RFFF) complication rates. METHODS A retrospective chart review was conducted for patients undergoing osteocutaneous RFFF reconstruction during an 8-year period. RESULTS One hundred fifty-five osteocutaneous RFFF procedures were performed. ...
With regard to retrogression trend of rangelands in central Zagross, many native plant species are expected to be increasingly on the verge of extinction. Therefore, for proper rangeland management the optimum harvest intensity of important plant species is an essential factor for rehabilitation and recovery of native rangeland species. This research was aimed to study the response of four rang...
To investigate the role of polyamines in pre- and post-harvest fruit development of 'Akatsuki' peach (Prunus persica (L.) Batsch.) we measured polyamine concentrations, activities of polyamine biosynthetic enzymes and expression of genes encoding these enzymes. Concentrations of the free polyamines, putrescine (Put), spermidine (Spd) and spermine (Spm) in pre-harvest fruit peaked 16 days after ...
In this position paper we raise the question of whether Con guration Management CM research has a future The new standard in CM systems typi ed by commercial products such as Adele ADC ClearCase Continuus CM and CCC Harvest largely satis es the CM functionality requirements posed by Dart This implies that research in the area of CM is either unnecessary or that we must nd new challenges in CM o...
Background: Timber harvesting in New Zealand’s plantation forests results relatively large volumes of woody residues being generated. While a proportion these are concentrated at the landings where trees processed, majority distributed throughout cutover. Harvest present biomass market opportunity, however managing un-merchantable remains essential as material can mass mobilisation risk. Quanti...
In this position paper we raise the question of whether Connguration Management (CM) research has a future. The new standard in CM systems|typiied by commercial products such as Adele, ADC, ClearCase, Continuus/CM, and CCC/Harvest|largely satisses the CM functionality requirements posed by Dart. This implies that research in the area of CM is either unnecessary or that we must nd new challenges...
Wheat growth in response to soil water deficit play an important role in yield stability. A field experiment was conducted for winter wheat (Triticum aestivum L.) during the period of 2002–2005 to evaluate the effects of limited irrigation on winter wheat growth. 80%, 70%, 60%, 50% and 40% of field capacity was applied at different stages of crop growth. Photosynthetic characteristics of winter...
research was carried out in 2007 on 7 native summer-ripening apple cultivars grown in kamal abad karaj research station. the 16 year-old plants were grafted onto seed rootstocks. the cultivars were ghandak-e-kashan, golab-e-isfahan, golab-e-kohanz, mashad, assali, ghermez-e-rezaieh and a new cultivar--koli-e-mahallat (syn. escr). the aim of the study was to identify changes in qualitative and q...
The spatial and temporal dynamics of Meloidogyne incognita, relative to soybean shoot and root growth in field microplots, were determined at 11 sampling dates during a growing season. The population dynamics of M. incognita on soybean were dependent on initial population (Pi), soil moisture, and root spatial distribution. Final egg and juvenile population densities were greatest in plots with ...
