Study Root System Structure and Characterstics in Wheat (Triticum aestivum L.) Cultivars Influenced by Applications of Sources of Fertilizer under Dryland Farming [PDF]
IntroductionAmong the nutrients used by the plant for the growth of nitrogen due to its participation in the structure of proteins, amino acids, coenzymes and nucleic acids are the main factors involved in plant growth and fertility. In recent decades, a

Converting Tree Diameter Measured at Root Collar to Diameter at Breast Height [PDF]
Pinyon pine (Pinus edulis), Utah juniper (Junipers osteosperma), and Gambel oak (Quercus garnbelii) are dryland tree species often measured for diameter at the root collar (drc) near groundline (Figure 1). This measurement point is below most main stem branching typical of dryland species.

Root Growth of Hordeum vulgare and Vicia faba in the Biopore Sheath
Biopores provide nutrients from root debris and earthworm casts. Inside large biopores, root function is limited due to the lack of root–soil contact. However, the immediate surroundings of biopores may hold a key function as “hotspots” for root growth ...

New class of integral bipartite graphs with large diameter [PDF]
In this paper, we construct a new class of integral bipartite graphs (not necessarily trees) with large even diameters. In fact, for every finite set $A$ of positive integers of size $k$ we construct an integral bipartite graph $G$ of diameter $2k$

Variation in resource acquisition strategies enables plants to adapt to different environments and may partly determine their responses to climate change. However, little is known about how belowground plant traits vary across climate and soil gradients.

Fine Root Length of Maize Decreases in Response to Elevated CO2 Levels in Soil
To assess the environmental risks of carbon capture and storage (CCS) due to underground CO2 leakage, many studies have examined the impact on plant growth; however, the effect of leaked CO2 on root morphology remains poorly understood.

Combining abilities and mode of inheritance for some root characteristics in sugar beet [PDF]
Sugar beet breeding is very complex because it involves numerous sugar beet root traits that must be measured and investigated, as a basis to create hybrids with high yield, high sugar content and appropriate root shape.

The diameters and number of nerve fibers in spinal nerve roots [PDF]
To investigate the anatomical and histological features of spinal nerve roots and provide base data for neuroanastomosis therapy for paraplegia.Spinal nerve roots from C1 to S5 were exposed on six adult cadavers. The diameter and the number of nerve fibers of each nerve root were measured, respectively, with a caliper and image analysis software.As for
