Background & Aim:A new sustainable tissue-based system is presented by plant hairy roots, preserving all of the several specialized types of cell with critical roles in allowing bioactive secondary molecules to be synthesized more consistently as usual. The system is also essential for studying the production of alkaloid in culture. Experimental: The ...

Soil-root plate dimensions and structural root architecture were examined on 46-year-old Sitka spruce (Picea sitchensis (Bong.) Carr.) trees that had been mechanically uprooted. Rooting depth was restricted by a water table, and root system morphology had adapted to resist the wind movement associated with shallow rooting. The spread of the root system and the ratio of root mass to shoot mass (...

abstract plant roots absorb water and minerals from soil solution. plant production is a function of root distribution and its activity in soil. by increasing root density in soil unit volume, roots absorb more water and minerals. this implies that knowledge of root development is an important factor for crop production. to determine the most suitable amount of water for the maximum development...

background: purple coneflower (echinacea purpurea l.) is one of the most important medicinal plants. hairy root culture of echinace, represent a valuable alternative to field cultivation for the production of bioactive secondary metabolites. objective: the present study investigates the effects of kno3, cacl2 and mgso4 concentrations on growth and the biosynthesis of cichoric acid in echinacea ...

Water yam (Dioscorea alata) is a staple crop for many of the poorest in the tropics. Yam tuber response to fertiliser application has been reported to be erratic. We hypothesised that this variable response could be due to the development of a suboptimal root system that would not allow the plant to capture the nutrients added with the fertiliser. To verify this hypothesis we studied during two...

Competition for nitrogen (N), particularly in resource-limited habitats, might be avoided by different N acquisition strategies of plants. In our study, we investigated whether slow-growing European beech and fast-growing sycamore maple seedlings avoid competition for growth-limiting N by different N uptake patterns and the potential alteration by soil N availability in a microcosm experiment. ...

Abstract Purpose Sustainable crop production could contribute to feed and fuel for the ever-increasing global population. The use of heavy agricultural machinery has improved efficiency farming operations increased food since 1950s. But their negative impact on soil includes changing structure resulting in deteriorating productivity environmental quality is being noticed several decades. purpos...

BACKGROUND AND AIMS Cereals have two root systems. The primary system originates from the embryo when the seed germinates and can support the plant until it produces grain. The nodal system can emerge from stem nodes throughout the plant's life; its value for yield is unclear and depends on the environment. The aim of this study was to test the role of nodal roots of sorghum and millet in plant...
