Riparian vegetation is known to exert a number of mechanical and hydrologic controls on bank stability. In particular, plant roots provide mechanical reinforcement to a soil matrix due to the different responses of soils and roots to stress. Root reinforcement is largely a function of the strength of the roots crossing potential shear planes, and the number and diameter of such roots. However, ...

Traditional plant breeding is often limited by the genetic diversity within a species. The use of biotechnology allows introducing into a plant, specific traits that come from the same or another plant species. In this paper, we focus on tissue culture of sunflower (Helianthus annuus L., Asteraceae), particularly related to rooting transgenic sunflower plantlets. Sunflower is notoriously recalc...

The intention of the new European legislation on rooting materials for pigs is to improve the welfare of pigs. The question is: which materials are suitable rooting materials for pigs? To answer this question the motivation for exploration in pigs is elucidated and the needs of the pigs in this context are discussed. The effects of different materials on the behaviour of pigs are listed and the...

Eucalyptus globulus Labill. has been used in Spain for decades as a cellulose source for the paper and textile industry. Since 1997, Sniace group has tested new provenances and families from 29 different Eucalyptus species to explore their capacity for biomass and bioenergy production. Plus trees for growth, wood quality, rooting capacity and tolerance to Mycosphaerella sp have been identified ...

A micropropagation protocol based on axillary bud proliferation has been developed from mature Lagerstromia parviflora adult tree. Nodal segments cultured on woody plant medium supplemented with 5.0 microl. BAP and 0.25 microm IAA gave maximum (86.9%) morphogenetic response. Proliferated shoots (10.7 per explants) were elongated to 3.9 cm within 6 weeks. In vitro produced micro-shoots were subj...

The influence of two carbon sources, sorbitol and sucrose on In vitro shoot proliferation and rooting of peach rootstock GF 677 was compared at 15, 30, 45 and 60 g l concentrations. The highest number of shoots per proliferated explant, usable shoots and shoots having maximum fresh weight were obtained on sorbitol at 30 g l. GF 677 does not seem to be an efficient utilizer of sucrose for In vit...

Many proposed self-stabilizing algorithms require an exponential number of moves before stabilizing on a global solution, including some rooting algorithms for tree networks [1, 2, 3]. These results are vastly improved upon in [5] with tree rooting algorithms that require only O(n3 + n2 · ch) moves, where n is the number of nodes in the network and ch is the highest initial value of a variable....

The need for improved crop water use efficiency calls for flexible modeling platforms to implement new ideas in plant root uptake and its regulation mechanisms. This paper documents the details of modifying a soil infiltration and redistribution model to include (a) dynamic root growth, (b) non-uniform root distribution and water uptake, (c) the effect of water stress on plant water uptake, and...

This paper will present an enhancement technique based upon splitting -rooting method in wavelet domain. Wavelets transform concentrate most of the energy in the approximation coefficient. In splitting signal, a twodimensional image is represented uniquely by a set of onedimensional signal, which carries the spectral information of the image at frequency points of specific sets. Using splitting...
