In order to stand firmly and efficiently uptake water and nutrients, plants need complex root stock architectures. The root system in maize is characterized by different root types, each of which contributes to the development and establishment of plants in a distinctive manner. During very early development, the embryonic primary and seminal roots are predominant, together with their post-embr...

Root architectural traits are important for the selection of crops and cultivars that are most efficient in the acquisition of nutrients and water from soil. Increasingly laboratory-based methods are being used to screen large numbers of plants and to measure selected architectural traits. Our research with temperate cereals demonstrates that while such methods may allow numbers of root axes an...

The spatial distribution of plant-available mineral nutrients in forest soils is often highly heterogeneous. To test the hypothesis that local nutrient enrichment of soil leads to increased root proliferation in the nutrient-rich soil zone, we studied the effects of nutrient enrichment on the growth and nutrient concentrations of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco), Scots pine (P...

BACKGROUND Plant root growth and development is highly plastic and can adapt to many environmental conditions. Sugar signaling has been shown to affect root growth and development by interacting with phytohormones such as gibberellins, cytokinin and abscisic acid. Auxin signaling and transport has been earlier shown to be controlling plant root length, number of lateral roots, root hair and roo...

Aeroponic culture is an alternative method for optimizing growth of different plants in controlled conditions. Aeroponic systems are an efficient tool for the root studies and improving medicinal root production. In order to study the feasibility of valerian (Valeriana officinalis L.) production in aeroponic systems and assessing the effects of different NAA concentrations (0, 0.1, 0.3, and 0.5...

The effect of electromagnetic field was examined on Zinnia (Zinnia elegans) seeds to enhance seed germination and early growth. The seeds were exposed to four magnetic strengths of 15, 100, 400 and 800 mT in four durations of 30, 60, 120 and 240 min. The experiments were carried out in two forms of laboratory germination and soil emergence. Results showed that magnetic field application enhance...

root-knot nematodes are one of the limiting factors in seedling production and new olive gardens establishment in iran. in view of find resistance cultivars to root-knot nematodes, importance of careful identification of species and races are clarified. in order to investigate root-knot nematodes on olive, soil and root samples of gardens and nursery in gorgan area were collected. in this study...

Exploration of the relationship between tooth dimensions, body size, and age is important in paleontology, forensic odontology and aesthetic dentistry. It is reasonable to speculate that tooth length is associated with stature since teeth contribute to facial height. This study aimed to determine whether there was an association between tooth length and stature and age in a sample of Sri Lankan...
