Abstract Aims Growth reductions and yield losses from drought could be mitigated by developing rice genotypes with more efficient root systems. We examined spatiotemporal responses to in order determine whether roots upper vs. deeper soil layers respond differently stress. Methods Root anatomical architectural phenotypes of two genotypes, Azucena (drought tolerant) IR64 susceptible), were measu...

Dendrocalamus brandisii is an edible bamboo species found in Southwest China and South Asia. However, there is limited information about the anatomical and chemical information of its culms for its utilization and processing. In this paper, the anatomical and chemical properties of different age culms were determined. There are three vascular bundle types found in its culms. The radial length-t...

0305-7364/0 * For corre { Present Durham, NC Paspalum dilatatum occupies di€erent topographic positions in the Flooding Pampa, Argentina. Populations from di€erent positions are subjected to various regimes of ̄ooding and drought, both of which may occur in the same growing season. We investigated the constitutive and plastic anatomical traits of P. dilatatum populations from habitats with contr...

ABSTRACT Physiological and structural alterations in broad beans (Vicia faba cv. Giza Blanka) in response to 10 M CuSO4, 10 M CdSO4 and a mixture of both solutions were recorded in 15and 25day-old plants. These treatments caused significant reductions in shoot height, leaflet area, fresh and dry weights, stomatal frequency, cell area in abaxial epidermis of leaflets, length and width of stomata...

thalamic pain syndrome, a type of central post-stroke pain (cpsp), may develops after a hemorrhagic or ischemic stroke and results in impairment of the thalamus. there is limited experience about gabapentin in treatment of central pains like cpsp.in a prospective observational study, the intensity of pain was recorded using the numeric rating scale (nrs) at the entrance to the study. patients e...

The vulnerability of vascular plants to xylem embolism is closely related to their stable long-distance water transport, growth, and survival. Direct measurements of xylem embolism are required to understand what causes embolism and what strategies plants employ against it. In this study, synchrotron X-ray microscopy was used to non-destructively investigate both the anatomical structures of xy...

A root pressure probe was employed to measure hydraulic properties of primary roots of maize (Zea mays L.). The hydraulic conductivity (Lp(r)) of intact root segments was determined by applying gradients of hydrostatic and osmotic pressure across the root cylinder. In hydrostatic experiments, Lp(r) was constant along the segment except for an apical zone of approximately 20 millimeters in lengt...
