The research was carried out with the objective of evaluating effect different substrates based on grass roots, air layering in lychee plants. seedlings were planted plastic pots a capacity 10 liters mixture soil, sand and barnyard manure (3:1:1). treatments composed Esfagno as control forage roots: Tifton, Jiggs, Mombaça Tanzânia. Ninety days after planting, their roots removed placed to dry f...

Understanding microbial transformations in soils is important for predicting future carbon sequestration and nutrient cycling. This review questions some methods of assessing one key microbial process, the uptake of labile organic compounds. First, soil microbes have a starving-survival life style of dormancy, arrested activity, and low activity. Yet they are very abundant and remain poised to ...

Survival and growth of longleaf pine seedlings depends upon a well-developed root system. Soil moisture is also critical for the seedling to emerge from the grass-stage. When longleaf pine seedlings emerge from the grass stage, they grow rapidly in height and diameter. Branches are often few in number and, if present, may have low photosynthesis rates. This growth pattern is seen on all longlea...

PURPOSE To measure anatomic variations of the lumbar plexus within the psoas in relation to the L2/3, L3/4, and L4/5 disc spaces and to delineate a safe zone to avoid nerve injury during retractor placement via the transpsoas approach. METHODS Six male and 6 female cadavers (24 psoas/ lumbar plexuses) aged 35 to 74 years were dissected. The lumbar plexus was isolated bilaterally. The L2, L3, ...

A full understanding of the growth and distribution tree roots is conducive to guiding precision irrigation, fertilization, other agricultural work during production. Detecting with a ground-penetrating radar repeatable detection method that does no harm earth surface roots. In this research, rapid accurate automatic was conducted on hyperbolic waveforms formed by root targets in B-scan images ...

The growth dynamics and phenolic content of mulberry (Morus sp.) fine roots (<1 mm diameter) were determined and examined in relationship to rhizosphere remediation of recalcitrant soil contaminants. Root turnover measurements of rhizotron-grown plants showed that 58% of the fine roots produced during a 6-month growing season (June-November) died at the end of the season. The concentration of p...

Arboreal palms have developed a variety of structural root modifications and systems to adapt to the harsh abiotic conditions of tropical rain forests. Stilt roots have been proposed to serve a number of functions including the facilitation of rapid vertical growth to the canopy and enhanced mechanical stability. To examine whether stilt roots provide these functions, we compared stilt root cha...

In this study, we quantified and analyzed the root-cutting process of garlic with a test bench pressure sensors on basis comparative analysis various information perception methods. On output value sensor, force curve roots was plotted, double round blade cutting module is optimized diagram. The innovative proposal slotted blades for root presented here. diameter 110 mm, center distance 100 thi...
