Most cultivars of apple trees are highly dependent on insects for success-ful pollination and fruit production. In this study, we evaluated the insectdiversity in apple orchards of southern Brazil and verified whether or notthere is a relationship between the diversity of insect visitors and thecharacteristics (weight, seed number, and symmetry) of the fruits of?Fuji?and?Gala?apples produced by the orchards. We also evaluated thediversity of insects on flowering weeds within apple orchards and com-pared it with the apple flowers. Diversity of anthophilous insects was low,in general, and differed between the regions. Furthermore, regarding in-sect diversity, orchards were grouped by management system: organicorchards were more similar to each other than to conventional orchards.The insect diversity of weed flowers was higher than apple flowers, butinsect abundance was greater on apple flowers, suggesting that weedsmay increase insect diversity within apple orchards and may sustain polli-nators. We found a positive effect of insect diversity on the number ofseeds of?Fuji?apples and of honeybee abundance on their weight, sug-gesting that honeybee management is important in the studied areas. Incontrast, we found no significant effect of insect diversity and abundanceon?Gala?apple characteristics. Despite this, the analyses of the seeds of?Gala?apples indicate that the orchards may suffer a pollination deficit,which could be overcome by improving insect pollination. These resultsreinforce previous findings that insect diversity is important for appleyield, but its influence varies with cultivar.

Conteúdo: |
Estudou-se o efeito do enxofre (S) na producao e composicao mineral de alfafa, num experimento conduzido em vasos de plastico com cinco litros de Latossolo Vermelho-Escuro distrofico de cerrado (Oxissolo). O delineamento experimental utilizado foi o inteiramente casualizado, em esquema fatorial (4x6), com cinco repeticoes. Foram estudadas quatro doses de S (0, 25, 50 e 100 mg dm-3 na forma de CaSO42H2O) e uma dose de sulfato de potassio (50mg dm -3 de S) em seis epocas de corte. Mediram-se as producoes de materia seca (MS) e teores de proteina bruta (PB), P, K, Ca, Mg e S na materia seca. As producoes de materia seca e teores de P e S variaram em funcao das doses de enxofre e das epocas de corte. As maiores producoes de MS foram observadas nos tratamentos que receberam 100 mg dm -3 de S, e as menores, nos que nao receberam S. Os dois ultimos cortes apresentaram as menores producoes, provavelmente em decorrencia do esgotamento dos nutrientes. Os teores de P aumentaram com as doses; foram maiores nos primeiros cortes que nos ultimos. O inverso foi observado com os teores de P1 o que indica efeito diluicao ou interacao negativa entre P e S. Os teores de PB, K, Ca e Mg variaram de acordo com as epocas de corte. |
