Field studies were conducted from 2006 to 2010 under weed-free conditions in south Texas and in the Texas High Plains to determine sesame tolerance to applied postemer‐ gence-directed herbicides. Injury was greatest when herbicides were applied to 15 cm of the main stem compared to herbicide applications made to 5 cm of the main stem height. Glyphosate at 0.84 kg ae/ha and pyrithiobac-sodium at...

Difficult access to 40-m-tall emergent trees in tropical rainforests has resulted in a lack of data related to vertical variations in wood CO2 efflux, even though significant variations in wood CO2 efflux are an important source of errors when estimating whole-tree total wood CO2 efflux. This study aimed to clarify vertical variations in wood CO2 efflux for emergent trees and to document the im...

BACKGROUND AND AIMS Morphology of crown shoots changes with tree height. The height of forest trees is usually correlated with the light environment and this makes it difficult to separate the effects of tree size and of light conditions on the morphological plasticity of crown shoots. This paper addresses the tree-height dependence of shoot traits under full-light conditions where a tree crown...

In order to study the effect of depth of drip placement in soil in subsurface drip irrigation, and fertilization time during irrigation events, on tuber yield of potato, an experiment was carried out in Jiroft area in 1389. This experiment was in a completely randomized block design with four replications, with depth placement of drip tape as the main plot, and fertilization time as the sub-plo...

The stem xylem conduit dimensions and hydraulic conductivity of chrysanthemum plants (Dendranthema x grandiflorum Tzvelev cv. Cassa) were analysed and quantified. Simple exponential relations describe conduit length distribution, height dependency of conduit length distribution, and height dependency of stem hydraulic conductivity. These mathematical descriptions can be used to model the xylem ...

Restoration of wet prairie in the central midwestern United States should include Prairie cordgrass (Spartina pectinata), but historic densities of this once dominant species are not easily achieved. Spartina pectinata was transplanted into a former agricultural field in three planting strategies: 20 small plugs, 4 medium-sized plugs, and a single large plug, with each treatment area totaling 0...

to investigate effect of calcium and growth medium on lilium (asiatic hybrid lilium bulbs “tresor” cultivar) and nutrients uptake, a factorial experiment based on completely randomized design was conducted by three levels of calcium in nutrient solution (2, 4 and 6 mm*) and five growth media (100% perlite, 70% perlite + 30% cocopeat, 50% perlite + 50% cocopeat, 30% perlite + 70% cocopeat, 100% ...
