‘Grasslands Nui’ perennial ryegrass (Lolium perenne L.), ‘Grasslands Wana’ cocksfoot (Dactylis glomerata L.), and ‘Grasslands Huia’ white clover (Trifolium repens L.) were surface-sown in spring into pre-treated hill country swards. Appearance, survival, and morphological development of seedlings were measured. Final seedling appearance of the grasses was similar (33% of seed sown) although ryegrass seedling appearance was more rapid than cocksfoot for the first 24 days after sowing. White clover seedling appearance was 58%. Survival of seedlings in plots laxly grazed before sowing was generally poorer than in hard-grazed or herbicide-treated plots. Species differed in seedling survival in the order: ryegrass= cocksfoot = white clover. Mean establishment levels 145 days after sowing were 30% for white clover, 23% for cocksfoot, and 25% for ryegrass. Herbicide treatment substantially improved seedling development for all 3 species. Analysis of the fate of grass seed showed losses were greatest imm...read more

Forage Legumes for Grazing and Conserving in Ruminant Production Systems
P. Phelan,Aidan P. Moloney,E. J. McGeough,J. Humphreys,J. Bertilsson,Edward G. O'Riordan,Padraig O'Kiely +6 more
TL;DR: Despite the numerous benefits of forage legumes for ruminant farming (to the farmer and wider society), their use is reported as being low or declining relative to other forages in many regions because their disadvantages are perceived to outweigh their advantages at farm level.

Natural Re-Seeding and Trifolium repens Demography in Grazed Hill Pastures. II. Seedling Appearance and Survival
TL;DR: Monitoring the appearance and survival of Trifolium repens seedlings from naturally deposited seed were monitored for 3 years under different sheep grazing managements and phosphate fertilizer inputs, and in four slope/aspect zones, in summer moist New Zealand hill country confirm that the species behaves essentially as a true perennial.

Effects of reclamation measures on plant colonization on lignite waste in the eastern Pyrenees, Spain
TL;DR: In this paper, the authors dealt with vegetation establishment on waste dumps in the montane and submontane belts of the eastern Pyrenees, where submediterranean Quercus humilis forests, Pinus sylvestris forests and mesoxerophilous pastures make up most of the landscape; these are considered as target communities for reclamation.

Changes in plant population density, composition and sward structure of a hill pasture during a pastoral fallow
TL;DR: A field study was conducted on two aspects of moist, low-fertility hill country with or without added fertilizer in the southern North Island of New Zealand, to investigate the changes in plant population density and sward structure during a full or partial pastoral fallow.

Introduction, production, and persistence of five grass species in dry hill country
TL;DR: Wana was the most productive, Matua was intermediate, and Maru phalaris was the least productive, however, and the role of new pastures in improving this extremely dry hill country must take second place to grazing management.

Seasonal variation in the seed banks of herbaceous species in ten contrasting habitats
K. Thompson,J. P. Grime +1 more
TL;DR: It is concluded that the major evolutionary force determining the nature of the seed bank is the selective advantage derived from mechanisms of seed dormancy and germination which allow seedlings to evade the potentially-dominating effects of established plants.

A comparative study of germination characteristics in a local flora
TL;DR: Under constant temperature conditions, the majority of grasses, legumes and composites germinated over a wide range of temperature, and the same feature was evident in species of ubiquitous or southern distribution in the British Isles.

A comparative study of germination responses to diurnally-fluctuating temperatures
K. Thompson,J. P. Grime +1 more
TL;DR: Responsibility to respond to temperature fluctuations in darkness was prominent in species of wetland where it appears to provide a mechanism whereby spring germination may be initiated by increasing irradiance and falling water table, and was conspicuous among species forming persistent seed banks.
Journal ArticleDOI
On the viable seeds present in the soil beneath pastures.
TL;DR: A definite indication was obtained that many seeds had a period of natural dormancy during which germination would not occur even under favourable conditions; a distinction was made between this phenomenon and the induced dormancy maintained in the soil by conditions unsuited to germination.
