Avaliou-se a resistência de vinte e cinco procedências e suas progênies de Ilex paraguariensis, oriundas da região do Planalto Norte Catarinense, quanto a incidência e severidade dos fungos foliares Colletotrichum sp e Cylindrocladium spathulatum, sob condições de campo, no período de 2017 a 2020. A incidência e severidade das infecções destes fungos foram similares, dentro do ano/período da avaliação, não ocorrendo diferenças significativas entre as procedências tanto para Colletotrichum sp. quanto para Cylindrocladium spathulatum. |

Several factors affect the flower formation process of temperate fruit species, such
as cultivar, geographic location, chilling unit accumulation, climatic conditions, etc. In
spite of numerous studies on the process of apple flower bud formation, little
attention has been given to the apple flower quality growing under inadequate
chilling conditions. In order to evaluate apple flower quality two cultivars, Gala and
Fuji, were studied in two different latitudes, in Southern Brazil ? BRA (26°50?S Lat,
50°58?W Lon) and in the Midwestern United States, in Ohio - USA (40°44?N Lat,
81°54?W Lon). Female and male floral organs from apple spur buds were assessed
at balloon stage; pistil length and weight, ovary diameter, number of anthers per
flower, pollen germination and pollen grains per anther and flower were calculated.
Apple trees in Brazil were sprayed with rest breaking compound to complete chilling
requirements. Female floral organs of both cultivars were considerably larger in the
USA compared to BRA. Pollen germination were 12-13% higher (Gala and Fuji,
respectively) in the USA than in BRA. Large differences were found between USA
and BRA both in the number of pollen grains per anther and per flower. Apple
flowers from the Midwestern United States, where climatic conditions are favorable
for apple growing, produced more pollen grains than those in Southern Brazil,
especially in Fuji flowers (183,392 and 50,749 pollen grains/flower, respectively). As
a conclusion, climatic conditions appeared to be important factors in determining
apple flower quality, and consequently, the potential for fruit production. MenosSeveral factors affect the flower formation process of temperate fruit species, such
