Abstract:
Different growth rates of young seedlings (genets) and plants grown from root pieces (ramets) of yellow toadflax could influence their respective competitive ability and their susceptibility to management techniques. Shoot production was similar for genets and ramets (approximately 10 shoots were produced 12 or 13 wk after transplanting or cotyledon appearance, respectively), but the rate of shoot biomass accumulation was higher for genets than for ramets. Genets consistently produced more underground shoots than ramets. Replanted underground shoots separated from their roots were able to prod

Increased alternative pathway activity was observed in shoots, exposed to 0.3 M sorbitol whereas increased cytochrome pathway activity, with a concomitant increase in the theoretical rate of ATP production, was found in the roots.

The current theory of pecan [Carya illinoinensis (Wangenh.) C.

Lack of nitrogen (N) reserves has also been proposed to be limiting after large crops, thus reducing return bloom. Annual production was determined for 12 individual trees for 3 years. Return bloom was monitored on four previous-season shoot types: 1) vegetative shoots, 2) bearing terminal shoots without a second g

Longitudinally cut epicotyl segments were observed to be the optimal explants followed by uncut epicotyls (not longitudinally cut).

However, more information is needed to define the role of the roots in artemisinin production in the plant.

There was little adoption of CMU, especially by women farmers, because it was labor-intensive and it sacrificed banana production for up to 2 years.

Abstract:
This paper discusses the physical mechanisms of enhanced fluid production from thin and slender porous structures such as hydraulic fractures and plant roots. The work shows how the end effect induces a large local pressure gradient in the medium which creates a converging flow pattern that focuses the fluid to the end region. As a result, a nearly singular flux density around the end develops which can promote the flux density distribution along the structure-medium surface, thus enhancing the production rate. For a given porous structure volume, a competition exists between the structure con

Abstract:
The authors studied the ability of narrow-leaved fireweed (ivan-tea) plants to form a second slope in the conditions of the North-Western region of the Russian Federation. It has been established that the intensive use of willow-tea herbage leads to the appearance of other types of herbs in it, mainly cereals, which blacken and compact the soil. As a result of this process, the shoot-producing capacity of the roots of the narrow-leaved fireweed and, as a result, the yield of the plantation decreases.

Test the hypothesis that phosphorus availability regulates ethylene production Clear differences were found between the two plants that were studied. In beans ethylene production is affected by P nutrition, tissue type, and stage of development. There are genotypic differences in the rate of ethylene production by various root types and in the differential in ethylene production when P treatments are compared.

Abstract:
This proposal is focused on examination of two plant interactions: parasitic with Orobanche, and symbiosis with arbuscular mycorrhiza fungi (AMF), and the involvement of a newly define plant hormones, strigolactones (SLs), in these plant interactions. In addition to strigolactones role in regulation of above-ground plant architecture, they are also known to be secreted from roots, and to be a signal for seed germination of the parasitic plants Orobanche. Moreover, secreted strigolactones were recognized as inducers of AMFhyphae branching. The present work was aimed at Generation of RNAi mutant

Original objectives: The basic goal of the present project was to increase our understanding of the cellular mechanisms operating during the gravitropic response of cut flowers, for solving their bending problem without affecting flower quality. Thus, several elements operating at the 3 levels o the gravity-induced signal transduction pathway, were proposed to be examined in snapdragon stems according to the following research goals: 1) Signaling: characterize the signal transduction pathway leading to the gravitropic response, regarding the involvement of [Ca2+]cyt as a mediator of IAA moveme

Permafrost thawing could increase soil contaminant mobilization in the environment. Our objective was to quantify metal accumulation capacities for plant species and functional groups common to Alaskan military training ranges where elevated soil metal concentrations were likely to occur. Plant species across multiple military training range sites were collected. Metal content in shoots and roots was compared to soil metal concentrations to calculate bioconcentration and translocation factors. On average, grasses accumulated greater concentrations of Cr, Cu, Ni, Pb, Sb, and Zn relative to forb

Abstract:
The laws that regulate relations between firms and workers in Mexico distinguish sharply between salaried and non-salaried workers, and they are at the root of the existence of informality. This paper provides a clear definition of informality, distinguishing it from illegality. Using Mexico's Economic Census, the paper shows that the majority of firms are informal but legal, that there are more small formal firms than large ones, and that some large firms are informal. It also shows that informality and illegality increased in the period 1998-2008. Using a simple model of monopolistic competi
