During the development of woody twigs, the growth in leaf may or may not be proportional to the growth in stem. The presence or absence of a synchronicity between these two phenologies may reflect differences in life history adaptive strategies concerning carbon gain. We hypothesized that sun-adapted species are more likely to be less synchronous between growths in total leaf area (TLA) and ste...

Tulip is one of the most important flowers to precocity. Treatment of tulip bulbs with gibberellic acid reduces the forcing period in the greenhouse resulting energy saving and reduces the tulip’s physiological disorders. This study carried out about three tulip cultivars includes ‘Lacourtine’, ‘Yokohama’ and ‘Red Favourite’. The results showed that gibberellic acid reduced significantly stem l...

gene transfer to plants and the production of transgenic plants with various purposes, such as improving the performance and quality, resistance to pests, diseases, etc., and of great importance are carried out gene transfer to plants performs to evaluate the transient and permanent gene expression. transient expression is quick, easy and simple and is not influenced by position effect compare ...

BackgroundHumeral stem designs for total shoulder arthroplasty have varied over the years, with a recent trend toward shorter stems. The purpose of this study was to examine impact humeral component length on ability restore native head anatomy.MethodsWe performed retrospective review including patients who underwent primary osteoarthritis between 2007 and 2017 complete operative reports adequa...

Telomere shortening occurs concomitant with organismal aging, and it is accelerated in the context of human diseases associated with mutations in telomerase, such as some cases of dyskeratosis congenita, idiopathic pulmonary fibrosis and aplastic anemia. People with these diseases, as well as Terc-deficient mice, show decreased lifespan coincidental with a premature loss of tissue renewal, whic...

Scanning transmission electron microscopy (STEM) is one of the most powerful characterization tools in materials science research. Due to instrumentation developments such as highly coherent sources, aberration correctors, and direct detectors, STEM experiments can examine structure properties at length scales functional devices down single atoms. encompasses a wide array flexible operating mod...

identification of quantitative trait loci is one of the important issues in breeding program especially under stress condition. plant material in the present study was a natural population including 72 tobacco genotypes. in order to apply osmotic stress, mannitol with 0.33 molar concentrations was used. the genotyping of individual were performed using 21 out of 35 primer combinations of aflp m...

Effects of various culture media and growth regulators on micropropagation of cherry rootstock, M × M60 were investigated in the present study. Stem cuttings of the current season growth were taken from mature stockplants and cultured on the establishment medium after disinfection. After four weeks, elongated shoots were cut and subcultured on the proliferation media including MS, DKW, QL and M...
