O processo de exploração da araucária no sul do Brasil reduziu drasticamente as
populações naturais da espécie, produzindo uma situação de ameaça e risco de extinção. Hoje a
araucária encontra-se nas listas de espécies ameaçadas de extinção. Assim o conjunto de
populações presente na FLONA pode representar a maior diversidade genética em unidades de
conservação. O objetivo deste trabalho foi estimar as taxas de cruzamentos em plantios e
populações naturais, visando estabelecer estratégias de conservação e manejo da espécie e
identificar áreas para a produção de sementes. Foram coletadas, no mínimo, três pinhas de dez
matrizes visando à caracterização genética de progênies para a obtenção de estimativas de
cruzamentos correlacionados. As taxas de cruzamento para Canoinhas, Anita Garibaldi e Mata
Nativa foram de 0,981, 0,974 e 1,049 respectivamente, esperados para uma espécie dióica. Como
a intenção inicial destes plantios era a produção de madeira, estes foram implantados em alta
densidade, fator importante para a produção de sementes, pois aumenta a competição entre os
indivíduos e provavelmente diminui a produtividade de sementes das áreas. O número de árvores
matrizes necessários para reter o tamanho efetivo de referência foi estimado através de valores
teóricos, para conservação de curto e longo prazo. |

The objective of this study was to analyze the relationship between aspects related to financial management and The objective of this study was to analyze the relationship between aspects related to financial management and scale of production with quality traits (total bacteria count - TBC; somatic cell count - SCC) and composition (protein, fat, lactose, total solids, and non-fat solids) of refrigerated bulk tank milk from 100 dairy farmers located in the south of Minas Gerais state, Brazil, by application of a semi-structured questionnaire. Dairy farmers were categorized according to the daily milk production: small (lower than 150 L); medium (151 to 500 L); and large (higher than 501 L). Chi-square tests and identification of possible relative risks between financial aspects and current regulation standards (Normative Instruction No. 62 of December 29, 2011, Ministry of Agriculture, Livestock and Supply) associated to TBC (higher 300,000 CFU/mL) and SCC (higher than 500,000 cells/mL) means from bulk tank milk among different milk scales productions were performed. Bulk tanks milk composition met the legislation standards and had not differ between scales of production; however, SCC means within all scales, and TBC of small farmers had not attended the legislation standards and differences were identified (P < 0.05). Regarding the financial management aspects, most farmers had no control over incomes, costs, nor calculated milk production cost, with decreased incidences as scale of production increased. Chi-square tests identified that producers that had no concern about milk quality payment bonuses had TBC means 2.95 times more likely (P < 0.05) to be above the current regulations. Small dairy farmers had a greater negligence of the costs management and hygienic milk production as compared to medium and large farmers. scale of production with quality traits (total bacteria count - TBC; somatic cell count - SCC) and composition (protein, fat, lactose, total solids, and non-fat solids) of refrigerated bulk tank milk from 100 dairy farmers located in the south of Minas Gerais state, Brazil, by application of a semi-structured questionnaire.
