This study was conducted to identify lines of subterranean clover (Trifolium spp.) with resistance to Meloidogyne arenaria (Neal, 1989) Chitwood, 1949, race 1; M. incognita (Kofoid and White, 1919) Chitwood, 1949, race 3; and M. javanica (Treub, 1885) Chitwood, 1949. A collection of 134 subterranean clover lines was evaluated and all had intermediate to high susceptibility. Root galling was neg...

The Rhizobium leguminosarum h o s t-range (Sym) plasmid, pJB5JI, is a 130 Mdal conjugative plasmid which carries the genes for host-specificity (i.e., for peas) and some of the genes for ni trogen-fixation. We have t ransferred plasmid pJB5JI into different species of Rhizobium and examined the symbiotic propert ies of the result ing transconjugants. The donor strain R. leguminosarum 6015 (pJB5...

Hadron masses are calculated in quenched lattice QCD in order to probe the scaling behavior of a novel fatlink clover fermion action in which only the irrelevant operators of the fermion action are constructed using APE-smeared links. Light quark masses corresponding to an mπ/mρ ratio of 0.35 are considered to assess the exceptional configuration problem of clover-fermion actions. This Fat-Link...

tion, pest or disease resistance, or reseeding ability (Harris, 1987; Brink et al., 1999). Widdup et al. (1996) found Small-type white clover, Trifolium repens L., plants predominate that only 10 of 98 ecotype collections from throughout in most closely grazed pastures in the southeastern USA. The role of relative seed production in stand persistence of white clover types the eastern USA were l...

As a plant produces more stolons and stolon branches it expands in area and is made up of clonal members. In established white clover (Trifolium repens L.) populations, seedBecause of decay of older stolons and environmental ling recruitment is rare and plants spread by clonal growth, which could lead to low intraspecific genetic diversity. To assess how populadisturbance, a clone frequently fr...

Large volume HPGe detectors are commonly used in applications that require good energy resolution and high detection efficiency, but are expensive and difficult to grow. Clover detectors consisting of 4 smaller crystals in a common cryostat are a possible alternative, but traditionally require complex readout electronics. In contrast, the DGF Pixie-4 is a compact, digital spectrometer providing...

A four-year rotation is desirable for potatoes. Proper rotation of crops is one necessary practice for avoiding the holding over of potato diseases in the soil. For potato wilt control at least a four-year rotation should be used. The one shown here makes use of corn, grain, clover, and potatoes. The best basic crop rotation for Western Oregon is grain, clover seed, clover hay, and a cultivated...

Field crop landraces are valuable genetic sources. Twenty populations of Persian clover (Trifolium resupinatum L.) collected from different areas of Iran were used in this study. DNA extractions were carried out using minipreparation method with equal amount of leaves from 30 plants of each population. DNA samples from 20 clover populations were evaluated using semi-random (ISJ) markers. Ten pr...

There have been many attempts to integrate object-oriented and functional programming. Solving the connicting requirements is dif-cult and only recently has a language, CLOVER, been designed that is both purely functional and purely object-oriented (and retains complete type safety). In this paper, we introduce the CLOVER rewrite rules by presenting a translation from CLOVER to a simple functio...

We describe a simple, conceptual forward analysis procedure for ∞-complete WSTS S. This computes the so-called clover of a state. When S is the completion of a WSTS X, the clover in S is a finite description of the downward closure of the reachability set. We show that such completions are ∞-complete exactly when X is an ω-WSTS , a new robust class of WSTS. We show that our procedure terminates...
