Large areas of moist upland grassland in KwaZulu-Natal are severely fragmented due to large scale farming of exotic trees. The aims of this thesis were to determine whether habitat fragmentation of these grasslands has a detrimental effect on plant-pollinator interactions and hence the reproductive output of the wildflower species occurring there and whether the magnitude of this effect can be predicted by breeding and pollination system characteristics. The 24 wildflower species included in this study appear to support a rich and diverse pollinator community, including long-tongued solitary bees, long-tongued flies, hawkmoths and sunbirds. Two thirds of the wildflower species appear relatively specialised in terms of pollination, with six species entirely dependent either on a single species or a specific functional type of pollinator for pollination. The majority of wildflower species (90%) were found to be incapable of autonomous self-pollination and thus dependent on pollinators for fruit and seed set. At least six species are obligately xenogamous. Little evidence was found for pollen limitation in undisturbed moist upland grassland, suggesting that these grasslands are characterised by high levels of pollinator activity. Greater levels of pollen limitation of reproductive output in habitat fragments was evident in two species, suggesting that depressed reproductive output in habitat fragments may be the consequence of a decrease in the quantity and/or quality of pollinator services. Significant detrimental effects of habitat fragmentation on reproductive output were evident in two thirds of the wildflower species, with 94% of the species exhibiting overall declines in seed set per flower from the continuous grassland site to the habitat fragments. The median decline in seed set per flower for the wildflower species was found to be 33.0%. Significantly more species experienced overall declines in reproductive output than would have been expected by chance alone. Only specificity of the pollination interaction in terms of number of pollinator taxa involved was found to be significantly related to percentage change in seed set from continuous to fragment habitats. This effect was diminished when other factors were included in a multiple regression. Results support Bond's (1994) hypothesis that degree of specificity in pollination systems is important in determining extinction risk of a given plant species. Declines in reproductive output of a range of wildflower species in grassland habitat fragments may affect the local persistence of these populations, particularly if recruitment is seed-limited. / Thesis (M.Sc.)-University of Natal, Pietermaritzburg, 2002.

Para isto no período de julho de 2011 a janeiro de 2012, foram realizados dois experimentos em São Luis, Maranhão. Em um experimento foram avaliadas doses de fósforo (0, 60, 120, 180, 240 e 300 kg ha-1 de P2O5) e em outro doses de potássio (0, 30, 60, 90, 120 e 150 kg ha-1 K2O), em delineamento de blocos casualizados, com quatro repetições. A colheita foi realizada aos 123 dias após o transplantio das mudas. As doses de fósforo influenciaram o teor de P no solo, matéria seca da parte aérea, matéria seca da raiz tuberosa, a produtividade total, e os acúmulos de P na matéria seca da parte aérea, da raiz tuberosa e total da planta. Houve ajuste linear para o teor foliar e ajuste quadrático para a produtividade comercial de raízes tuberosas, sendo que a máxima produtividade (1,68 kg m-2) foi obtida com a dose estimada de 191 kg ha-1 de P2O5. A dose ótima econômica foi de 104 kg ha-1 de P2O5, correspondendo a 54% da dose que maximizou a produtividade comercial e a parte aérea foi o órgão que mais acumulou P. As doses de potássio influenciaram o teor de K no solo, teor foliar, produtividade total e produtividade comercial, e os acúmulos de K na matéria seca da parte aérea, da raiz tuberosa e total da planta. A máxima produtividade comercial (2,43 kg m-2) foi obtida com a dose estimada de 85 kg ha-1 de K2O. A dose ótima econômica foi de 71 kg ha-1 de K2O, correspondendo a 83% da dose que maximizou a produtividade comercial, sendo a parte aérea o órgão que mais acumulou K / The present work had as objective to evaluate phosphorus and potassium rate in mineral nutrition and yield of the sweet potato biofortified, in a yellow red ground dystrophic cohesive of the Itapecuru formation. For this, in the period from July of 2011 to January of 2012, two experiments were realized in São Luís, Maranhão. In an experiment, it was evaluated phosphorus rate (0, 60, 120, 180, 240 and 300 kg ha-1 of P205) and in another one, potassium rate (0, 30, 60, 90, 120 and 150 kg ha-1K20), in a lineation of randomized blocks, with four repetitions. The harvest was realized at 123 days after the transplanting of seeding. The phosphorus rate influenced on the percentage of P in the ground, the dry matter of the aerial part, the dry matter of the tuberous root, the total yield, and the accumulation of P in the dry matter of the aerial part, the tuberous and total root of the plant. Occurred the linear adjustment to the foliar percentage and quadratic percentage to the commercial yield of tuberous roots, where the maxim yield (1,68 kg m-2) was obtained with the estimated rate of 191 kg ha-1 of P205. The economical optimal rate was of 104 kg ha-1 of P205, corresponding to 54% of the rate that maximized the commercial yield and the aerial part was the organ that had more accumulation of P. The potassium rate influenced the percentage of K in the ground, the foliar percentage, commercial and total yield, the accumulation of K in the dry matter of the aerial part, the total and tuberous root of the plant. The maxim commercial yield (2,43 kg m-2) was obtained with the estimated rate of 85 kg ha-1 of K20. The economical optimal rate was of 71 kg ha-1 of K20, corresponding to 83% of the rate that maximized the commercial yield and the aerial part was the organ that had more accumulation of K

However, the fertilization with micronutrients is also needed for plant nutrition, including molybdenum, with a fundamental role together with the nitrogen in the synthesis of many essential metabolic reactions indispensable for plants. In this sense, the objective of this study was to evaluate the effect of different doses of Mo and N in the second crop corn, and its residual effect on soybean grown in the summer harvest. The experiment was conducted at the Experimental area of UNESP - Ilha Solteira Campus, located in Selviria county, Mato Grosso do Sul State. The first experiment with corn in experimental design was a randomized block design with split plot design with four replications, where were tested four nitrogen rates (0, 90, 135 and 180 kg ha -1 ) in the plot, having the urea as N source, and five doses of molybdenum (0, 10, 20, 30 and 40 g ha -1 ) in the sub-plots. The crop was sown on 05/25/2013, in spaced 0.90 m using the hybrid DKB 390 Pro2. The second experiment was conducted with soybean in the summer crop on the same plots of the previous experiment. The crop was sown on the date of 11/13/2013, in spacing of 0.45 m using the cultivar BRS Valiosa RR. Soybeans were conducted without molybdenum and nitrogen application to evaluate the residual effect of the treatments used in the corn experiment. We evaluated the productive and morphological components for corn (plant height, ear height, grain yield, thousand grain weight, number of grain rows, number of kernels per row, and diameter of the ear) and soybeans (plant height, number of pods per plant, number of branches per plant, thousand grain weight and grain yield).

In this sense, it is aimed to verify the effect of the vibration of plants in the production of american pepper protected with open and closed sides cultivation. The experiment was conducted at the Experimental Farm of UNESP/FCA located in the city of São Manuel-SP. There were six treatments in a split plot design, with two instalments, one with vibration and other without vibration of the plants in subplots the three cultivars (Dirce, Dínamo and Doce Comprida). The plants were vibrated shooking on the wire where it attaches the tutor (bamboo cane) by hand for about 5 seconds, twice a day. The design was a randomized block design with three replications. The same experiment was conducted in two environments: with and without closing the sides. The characteristics were evaluated: weight and number of total and marketable fruit (no visible defects) per plant, percentage of marketable fruits; mass, diameter and fruit length , weight and number of seeds per fruit , and plant height. Fruit production was much higher in the environment with closed sides with 24 marketable fruits per plant while in open areas there were seven. The vibration of plants of american peppers did not affect yield, length, diameter and average fruit weight. Just cultivating Doce Comprida gave higher seed production per fruit in the open environment in relation to confinement, in the absence of plant vibration, averaging 259 and 126 seeds per fruit, respectively. The vibration indoors benefited cultivar Doce Comprida.

The research was done inside on a glass green house at the UNESP - College of Agronomical Science, Rural Engineering Department (Botucatu - SP - Brazil). Two trials were done to evaluate biomass, seedling height and diameter development. The first trial, using underground water on 17 cm, 31 cm and 45 cm depth, with or without coverage fertilization with N-P-K. The second trial was done with 28 flowerpots (12 liters each) and 3 seedlings per unit. The experimental design, used to evaluate the height and diameter growth and hydric potential and relative plant water content, was: 1- without water deficit and without coverage fertilization; 2- with water deficit and without coverage fertilization; 3- without water deficit and with coverage fertilization; 4- with water deficit and coverage fertilization. The underground water result showed that 31 cm and fertilization was better for seedling growing rather that 17 cm and without fertilization. The fertilized treatments showed higher plant high and diameter comparing to non fertilized samples, using Tukey test at 5%. For dry plant matter, the best results were obtained with 31 and 45 cm underground water level. The seedling root system dry mass was decrement along the soil profile. The treatment with underground water of 31 cm and fertilization was superior according to Tukey test at 5% of probability and the treatment with underground water of 17 cm and without fertilization was inferior for root dry mass (g). All the others treatment didn’t have statistical differences. It didn’t happen the irrigation effect on the plant high development; however the fertilized treatment had superior development compared to unfertilized samples.
