considering the ease of isolation and high expansion potential of pulp stem/progenitor cells isolated from wisdom and primary teeth they have been implicated as the most reliable autologous cell source in dental tissue engineering. meanwhile, different isolation methods have remarkable impacts on the expansion potential of adult stem cells. in enzymatic digestion method extracted teeth as denta...

This study investigated the effect of blade oblique angles and cutting spee...

the shear strength and shear energy per unit area, as well as the force and energy required for picking flowers, are important parameters in the design and development of harvesting mechanisms. in this study, shear strength and shear energy per unit area of saffron (crocus sativus l.) stems were determined at different bevel angles and shear velocities. the force and energy required for picking...

The performance of seed tubers harvested from potato plants grown from sprout cutting, stem cutting and conventional seed tubers against PVY and PLRV were investigated. Sprout cutting, stem cutting and conventional seed tubers of variety Diamant were planted and second and third generation seed tubers were harvested. The least incidence of PVY and PLRV was recorded when seed tubers from sprout ...

Magnolia wufengensis, a rare ornamental tree species, is now in huge gap between market demand and actual supply of seedlings. As cutting propagation one the most important means to solve shortage seedling supply, this study developed an efficient procedure M. revealed morphological histological changes adventitious root formation, explored rhythm correlation rooting process physiological bioch...

Two different propagation procedures including aeroponics and soil systems were compared for the minitubers production in potato. The minitubers were evaluated for several quality characters. The plant materials were from three cultivars, Agria, Marfona and Savalan. The plantlets were grown in aeroponics and soil production systems at a plant density of 100 plants per m-2 and stem length, root ...

Studies were conducted in early 2003 to determine the effect of root source and length on yield of adventitious shoots and plant yield from root cuttings of Arkansas-developed thornless blackberries. In the first study, roots from ‘Arapaho’ and ‘Apache’ plants grown in an aboveground bed containing commercial potting soil were compared to field-grown roots. Bed-grown roots averaged 6.9 shoots p...
