Abstract (sommario):

Clover root weevil arrived in New Zealand about 20 years ago causing major loss of productivity as it progressively spread across the whole country. It is now largely controlled by an introduced parasitic wasp biocontrol agent Microctonus aethiopoides (Irish ecotype). However, management of insect pests should not rely on a single mechanism and clovers resistant or tolerant to this weevil would be a useful augmentation for farmers to have. This investigation reports on the suitability of 22 clover cultivars to attack from the weevil. Results have shown that contrary to popular belief, red clovers are not universally less favourable to the weevil than white clovers and usefully, within both species cultivar differences point to the possibility of resistance to this pest. Keywords: Clover root weevil, Sitona obseletus, clover cultivars

Abstract (sommario):

The effect of leaf feeding by adult clover root weevils on the isoflavonoid content of red and white clovers was investigated in a glasshouse experiment. Lines of both clovers previously selected for variation in formononetin content were used. A higher percentage of white clover leaves than red clover leaves were damaged by the weevils, and the high formononetin red clover was least readily eaten. The formononetin content of the white clovers did not differ between the selections, was much lower than in the red clovers, and did not change in response to weevil feeding. In both red clover lines, formononetin and biochaninA levels rose in response to weevil feeding, suggesting that both compounds have antifeedant properties against clover root weevil. Because high foliar levels of oestrogenic compounds like formononetin threaten fertility of grazing sheep it is concluded that plant breeding programmes should increase the levels of formononetin and/or biochaninA in clover roots to mitigate the impact of weevil larval feeding on roots and nodules.

Abstract (sommario):

Clovers (Trifolium spp.) are vulnerable to a large number of invertebrate pests so pest resilience amongst 19 leading commercial or near release New Zealand-bred clover cultivars was compared. Laboratory feeding choice tests comparing foliage from the test clovers against Grasslands Kopu II as the standard confirmed that red clovers (T. pratense) were less preferred than white clovers (T. repens) by adult clover root weevil and clover flea. Grey field slug showed no preference between red and white clovers, with the white clover Grassland Prestige performing the best. Porina larvae had lowest weight gains on strawberry clover (T. fragiferum). Subsequent tests using neonate greenheaded leafroller larvae and an artificial diet made with freeze-dried foliage from cultivars in the most and least preferred subgroups indicated antifeedant compounds, rather than leaf morphology, are likely responsible for differences in feeding preferences between red and white clovers.

Abstract (sommario):

Three on-farm sites where plantain was sown with legumes and/or perennial ryegrass were monitored for 2 years post-sowing. On two cultivated sites in Hawke's Bay, newly sown plantain/clover pastures produced 20% and 22% more dry matter, respectively, than newly sown ryegrass/clover or established pastures. On an uncultivatable site in coastal Wairarapa, aerially oversowing of plantain and clover resulted in 282% more dry matter than resident pasture on north faces. Plantain pastures had higher clover contents and lambs had faster growth rates and higher dressing-out percentages than lambs finished on traditional ryegrass/clover pastures. Plantain and a mix of annual and perennial clovers offer a promising alternative to ryegrass-based systems in dryland. As with lucerne, plantain and erect annual clovers need to be rotationally grazed to prevent damage to the crown and growing points. The success of these alternative forages in dryland farming systems will depend on farmer willingness to embrace new grazing management techniques. Keywords: forages, plantain, arrowleaf clover, Persian clover, balansa clover, white clover, red clover oversowing, live weight gain.

Abstract (sommario):

Native forage legumes may have potential for summer/fall grazing in semiarid prairie regions in mixture with grasses. The objective of this study was to evaluate two native clovers in binary mixtures with the introduced grasses when harvested in July and September to simulate late summer or fall stockpile forage. Eight binary clover–grass mixtures were seeded in a split-plot design with 4 replications at Swift Current, Saskatchewan, Canada. Mixtures included (i) AC Antelope white prairie clover (WPC)-Admiral meadow bromegrass (MBG), (ii) WPC-AC Success hybrid bromegrass (HBG), (iii) WPC-Bozoisky Russian wildrye (RWR), (iv) WPC-TomRWR, (v) AC Lamour purple prairie clover (PPC)-AdmiralMBG, (vi) PPC-AC SuccessHBG, (vii) PPC-BozoiskyRWR, and (viii) PPC-TomRWR. Clover establishment differed (p = 0.03) in July where WPC had 77.8% greater proportion in mixture than PPC, although both clovers increased (p < 0.001) in September to similar legume proportions, 663.2 and 876.1 kg/ha, respectively. Clovers with bromegrasses produced 41.9% more forage dry matter yield in summer than clovers with Russian wildryes (p < 0.001), though the latter mixtures had slightly better nutritive value (avg. 7.0% vs. 5.2% crude protein (CP). Clover–MBG exhibited higher (53.6%) in vitro organic matter digestibility (IVOMD) than Clover–HBG (51.2%) (p = 0.04). Purple prairie clover with grass or both clovers in mixture with bromegrasses, produced adequate forage biomass for summer and fall grazing, except clovers with Bozoisky RWR, while clovers with both RWR cultivars had acceptable forage nutritive value for summer in this semiarid prairie region.

Abstract (sommario):

Annual and perennial clover species may differ in green manure value. Seven clover (Trifolium) species were grown as annual crops on low fertility (Breton) and high fertility (Edmonton) soils in Alberta. Four annual clovers [balansa (T. michelianum Savi), berseem (T. alexandrinum L.), crimson (T. incarnatum L.), and Persian (T. resupinatum L.)], three perennial clovers [alsike (T. hybridum L.), red (T. pratense L.), and white Dutch (T. repens L.)] and a non-legume reference crop [fall rye (Secale cereale L.)] were ploughed-down as green manure in autumn, and followed by barley (Hordeum vulgare L.). Annual clovers had greater biomass yields than perennial clovers, and berseem clover had the highest yield. At Breton, mean biomass N content was greater for perennial clovers (2.9 g N kg-1) than annual clovers (1.9 g N kg-1). Clover biomass at Breton yielded an average of 77 kg N ha-1, with N derived from the atmosphere averaging 88% by N difference method and 75% by 15N natural abundance method. At Edmonton, the green manures had few effects on soil nitrate and subsequent barley yields. At Breton, all clover green manures except balansa increased barley yields, and grain yields were greater following perennial clovers than annual clovers in one year. Annual clovers will provide forage biomass and add N in areas where rainfall is adequate, and they may be preferable under zero tillage. However there is no advantage of annual clovers, relative to perennial clovers, in terms of N supply.Key words: Green manure, clover, Trifolium species, nitrogen fixation

Abstract (sommario):

The release of effective inocula for new perennial clovers into cropping zones where subterranean clover is important might compromise N2 fixation by this valuable annual clover if symbiosis between the new inoculants and subterranean clover is not optimal. To assist our understanding of the interactions between clovers and their microsymbionts, rhizobial strains and clovers from South and equatorial Africa, North and South America, and the Euro–Mediterranean regions were tested. Glasshouse-based studies of the cross-inoculation characteristics of 38 strains of Rhizobium leguminosarum bv. trifolii associated with 38 genotypes of annual and perennial Trifolium spp. from these world centres of diversity were undertaken. Less than 7.5% of the perennial clover symbioses were effective whereas 40% of associations were effective for many of the annual clover species of Euro–Mediterranean origin. There was substantial specificity within the African clovers for effective nodulation. Rhizobial strains from the South American perennial T. polymorphum or from the African clovers were unable to nodulate subterranean clover effectively. Also, 7 of the 17 strains from these regions were unable to form nodules with the less promiscuous Mediterranean annual clovers, T. glanduliferum and T. isthmocarpum. Fifty-three of about 400 cross-inoculation treatments examined, which included annual and perennial clovers, were incapable of forming nodules, while only 65 formed effective nodules. There are 2 barriers to effective nodulation: a ‘geographic’ barrier representing the broad centres of clover diversity, across which few host-strain combinations were effective; and, within each region, a significant ‘phenological’ barrier between annual and perennial species. Clovers and their rhizobia from within the Euro–Mediterranean region of diversity were more able to cross the phenological barrier than genotypes from the other regions. It appears that only the relatively promiscuous clovers, whether annual or perennial, have been commercialised to date. The data indicate that, for perennial clovers, it will be a substantial challenge to develop inocula that do not adversely affect N2 fixation by subterranean clover and other annual clovers available commercially, especially if the perennial clovers were originally from Africa or America. Some future strategies for development of inoculants for clovers are proposed.

Abstract (sommario):

Clover inclusion may increase the sustainability of certain low-maintenance turfgrasses. However, selective weed control within mixed turfgrass–clover swards proves problematic because of clover susceptibility to herbicides. Research was conducted to identify common turf herbicides that are tolerated by threeTrifoliumspecies, including white clover, ball clover, and small hop clover, within low-maintenance turfgrass. Leaf and flower density, as well as plant height, were measured 4 wk after treatment as indicators of clover response to 14 herbicides. The threeTrifoliumspp. were moderately tolerant of bentazon (< 35% decrease in leaf density, height, or flowering). Simazine was well tolerated by white clover (< 5% decrease in all response variables), yet moderate injury to ball clover and small hop clover was observed (> 32% decrease in leaf density and > 27% decrease in flower density). Pronamide was well tolerated by white and ball clovers, with no effect on measured response variables; however, pronamide decreased small hop clover height and flower density (38 and 42%, respectively). Imazethapyr and imazamox were moderately well tolerated by white clover and small hop clover (< 39% decrease by all response variables), yet ball clover may be more susceptible to these herbicides than was anticipated based on previously reported tolerance. The herbicides 2,4-DB, halosulfuron, and metribuzin were well tolerated by white clover, with no effect on measured response variables; however, results suggest ball and small hop clovers were less tolerant. Clopyralid, 2,4-D, glyphosate, imazaquin, metsulfuron-methyl, and nicosulfuron resulted in varying degrees of injury across clover species and response variables, but, in general, these herbicides may not be viable options when attempting to maintain any of the three clover species tested. Further research is needed to quantify long-term effects of herbicide application on sward composition and clover succession.

Abstract (sommario):

Clovers are commonly included as utility plants within mixed grass swards, such as pastures and roadside right-of-ways. As such, they provide supplemental nitrogen, quality forage, and insect habitat. Yet weed control within mixed swards is often hampered by the lack of selective herbicides that are tolerated by clovers. Differential tolerance of legumes to common row-crop and pasture herbicides has previously been reported, yet little information is available that is specific to clover species. Herbicide injury of clover is often inconsistent, hypothetically due to differential species tolerance. Field and greenhouse experiments were conducted with the objective of testing differential tolerance amongst four clover species. Our experiments suggest varying tolerances amongst clover species and common broadleaf herbicides. Only imazaquin control differed due to species; however, treatment by clover interactions were further demonstrated due to variable reductions in clover height. Imazaquin, 2,4-D, 2,4-DB, and triclopyr height reductions differed due to clover species. Differential clover response to herbicide treatment should be an important consideration when managing mixed grass–clover swards and should be accounted for in future research. On a more practical level, our experiments demonstrate a range of herbicides that effectively control clover species, including atrazine, dicamba, clopyralid, 2,4-D, triclopyr, metsulfuron, and trifloxysulfuron. However, results suggest that 2,4-DB, imazethapyr, and bentazon are candidate herbicides for weed control in scenarios in which clover is a desirable crop.

Abstract (sommario):

This work is regarded as casting symbolic spells: spells for the health of degraded prairie remnants, the thriving of bats, fearlessness, romantic love. Spells are a call for transformation, and images of transformation occur throughout the work - snakes molting, mummies decaying, insects in metamorphosis. Whether examining a construction site or the end of a relationship, the author is asking herself "when is change good and when is it catastrophic?" Right now the author is looking closely at punk, witchy contemporary artists like Rosy Keyser, Maria Loboda, Marisa Merz, Victor Man, and Sterling Ruby. The author is also influenced by artists who smash a lot of pictures together, or have an overwhelming "Google Image Search" aesthetic like Isa Genzken, Anne de Vries, and Camille Henrot. At the same time, the author is drawn to old, mysterious, precious things (Viking runes, Taureg amulets, Hilma af Klint paintings, archaeological digs) and have an abiding love of altarpieces, medieval objects, Botticelli, and Van der Weyden. Depictions of the Expulsion from the Garden serve as regular references. In them, the author finds an entwinement of her interest in ecological and romantic upheaval and a relationship to the body and touch that is both tender and precarious. The author wants to make the work that's about all the inexhaustible things: love, death, history, sex, mysticism, family, nature. It's not there yet, but she is working to make them happen.

Abstract (sommario):

The stories collected within this thesis are, by and large, tales of loss. To be more specific, the following losses occur: one brother, two lovers, a doting former sister-in-law, one's own health, certain freedoms, (including a room with a view,) life itself (twice,) and innocence, forever gone in an absent-minded moment of brutality. Chronology is toyed with somewhat, more so towards the beginning of this collection, less so towards the end. The opening story, "Three Kitchens," is comparatively unique in that it is the sole work written in the first person. While it fits thematically within the larger whole, it has been placed at the beginning based on this one difference. "Birdsong," a tale of regret centered on not leaving when it is prudent to do so, is the next story. The remaining four stories can be thought of as a pair of twins; "Candelabrum," and "The Becoming of Felix Wagner," both occur in 1961 East Berlin, during the construction of the Berlin Wall, (and are more closely entwined than are the last two stories.) "Hernandez," and "Hank Flowers," occur within the span of a few days in mid-1980's rural Pennsylvania, though are only bound together by the thinnest of threads.

Abstract (sommario):

A white clover ( Trifolium repens ) system, based on one ozone-sensitive (NC-S) and one ozone-resistant (NC-R) clone, has been developed as an indicator to estimate the effects of tropospheric ozone on plant biomass production. A reduction in the vegetative biomass ratio (NC-S/NC-R) of the clones was correlated with increasing concentrations of ozone during a 28-day exposure period. However, the mechanism of ozone sensitivity or tolerance at the biochemical or molecular level is not known. Superoxide dismutase isozyme activities in the two clones did not respond differently to ozone treatment. However, catalase activity increased somewhat more in the leaf tissue of NC-R, compared to NC-S, after ozone treatment. Two-dimensional polyacrylamide gel electrophoresis (PAGE) showed the presence of two proteins (Ozone-Response-Proteins, ORPs) that were more responsive to ozone in the tolerant genotype than in the sensitive one. After ozone treatment for three days, the ORPs were four-fold higher in leaf tissue of NC-R compared to NC-S. Also, the amount of the ORPs was twenty-fold higher in leaf tissue of ozone-treated NC-R than in that of control NC-R. These proteins have apparent molecular weights of 21.5 kD and 23 kD and isoelectric points of 4.1-4.4 on SDS-PAGE gels. The filtrate of a 100 kD concentrator showed that the native molecular weights of the ORPs were less than 100 kD. The results obtained from a study of field samples demonstrated that protein content in leaf tissue of both NC-R and NC-S was positively correlated with ORP content.

Abstract (sommario):

Adventitious root growth from the crown of red clover constitutes a major portion of the root system in older stands. Two 2 yr old production fields and 3 yr old research plots were sampled in springs of 1988 and 1989 to determine the relationship between spring vigor and two root types of red clover. A higher average spring vigor rating was generally associated with the presence of well developed adventitious roots.
Five hundred and fifty-six red clover plants were dug in the fall of 1988 from a space planted (1 x 1 m centers) nursery established in the spring of the same year. Two divergent populations of 55 clones each were produced based on either a low or high score for adventitious root growth. The progeny of 32 single-crosses made within and between the two populations was evaluated for flowering habit and root types under spaced planting conditions during the 1989 growing season.
Six red clover cultivars were established in solid seedings to monitor adventitious root growth at three sampling dates.

Abstract (sommario):

Low input grassland systems depend on cheap fertiliser sources, such as clover or animal manures, to maintain sward productivity. Clover is a poor competitor for phosphate (P2O5) and potash (K2O), a mixed sward will therefore require adequate inputs of these nutrients. Nitrogen (N) leads to the suppression of clover. Recycling of cattle slurry would be followed by small N and P2O5 but large K2O effects. The K2O and P2O5 would be expected to have a beneficial effect on the clover while the N would be detrimental. Two investigations into the balance between these aspects of cattle slurry on clover in a mixed sward were performed. Slurry N led to clover suppression, this effect was strongest following spring applications. K2O had a beneficial effect on the clover, the P2O5 supplied had a small positive effect but was insufficient to fully meet the clover's requirements. There was a suggestion that these beneficial effects were strongest following summer applications. In addition to these fertiliser effects, non nutritional secondary effects often followed slurry with a deleterious action on the clover. These effects were most common following higher rates of slurry and summer applications. A further investigation was performed to establish the effect of varying clover variety and companion grass species on the clover's susceptibility to cattle slurry N and secondary effects and the nature of these effects following pig slurry applications. This revealed that clover's susceptibility to slurry N was inversely related to leaf size. No difference in secondary effects susceptibility arose with different clover varieties or companion grass species. Pig slurry was not accompanied by secondary effects. Slurry applications to mixed swards may therefore have positive and negative nutritional effects on the clover component but non nutritional secondary effects may also act with a deleterious effect on the clover.

Abstract (sommario):

In the Kaliningrad region of a clover — the main component of long-term fodder herbs — quickly weaken, give few seeds and quite often completely drop out. Even in favorable conditions, in mixes of herbs of the second year of use, clovers there is no more than one third. One of the main reasons — damage by the stem clover weevil of Apion seniculus Krby. Escaping of the created situation is the developed package of measures on increase of seed efficiency of meadow clover in the Kaliningrad region, including cutting of stalks in a butonization phase.

Abstract (sommario):

In Colombia, the specialized dairy systems are supported in forages use. However, edaphic and weather features are related with production and compositional quality of grasses. In this sense, it is important to recognize resilient fodder species to pastoral systems. The objective was to evaluate the establishment (covert proportion (%, Cp) and adaptation grade (0 to 3 scale, Ag) and production (dry matter yield (kg DM.ha-1, Dm) and net energy lactation (Mcal.kg DM-1 , Nl) of five perennial ryegrasses (three diploid and two tetraploid) and three clovers (two reds and one white) in two regions of Colombian highlands (Tuta and Mosquera at 2600 m.a.s.l.)
