Abstract: This study evaluates the emergence and initial development of sugarcane cultivars with different bud sizes, based on the system of pre-sprouted seedlings (PSS). Early sugarcane cultivars (RB966928, RB855156 and IACSP91-1099) were evaluated. These evaluations comprised three positions of the sugarcane stem (tip, middle and base) and four types of sugarcane propagules (mini-stem and 3 bud sizes with different diameters: 22 mm (1), 29 mm (2) and 35 mm (3)). Three trials were performed, each with a different cultivar. The experimental design for each cultivar was a randomized block in a 3x4 factorial scheme (stem position x propagule size (vegetative material)) with 4 replicates. Emergence was evaluated daily, and from these evaluations the emergence speed index (ESI) was calculated. Plant height, shoot dry mass and root dry mass were also assessed. Data were submitted to analysis of variance with interaction, and the Tukey test was applied. When simple variable transformations were not enough to meet the assumptions of normality and homoscedasticity, the non-parametric Friedman test was used. ESI indicated that the best type of propagule was the mini-stem, and for cultivars IACSP91-1099 and RB855156 the best performing position was the tip. The Friedman test indicated significance of the causes of variation related to propagule size and stem position for shoot dry mass in all evaluated cultivars. In addition, the test indicated significant variation of root dry mass for cultivars IAC91-1099 and RB966928 between propagule sizes and the stem positions. The height of cultivar IACSP91-1099 showed interaction between the different propagule sizes and stem positions. The greatest increase of height in sugarcane seedlings occurred for the mini--stem propagule and tip position. Cultivars RB855156 and RB966928 also showed interaction between the different propagule sizes and stem positions. Cultivar RB855156 showed the highest plant height with the mini- -stem propagule at the tip position, however it did not differ statistically from the propagule with size 3 at the tip and middle positions. The mini-stem and the bud with size 3, removed from the tip of the stem, are the best alter-natives for seedling production.

ABSTRACT - The objective of this work was to evaluate the reaction of common bean (Phaseolus vulgaris) lines to Sclerotinia sclerotiorum, the aggressiveness of the isolates, and the inheritance of resistance to white mold, under two environmental conditions. The experiments were carried out under field and greenhouse conditions. In each one, four isolates were inoculated in 14 common bean lines using the straw-test inoculation method and severity on plants. No common bean line with a high level of resistance to white mold was identified, and most of the lines were moderately resistant to the pathogen. In general, the BRS Campeiro, BRS Radiante, BRSMG Talismã, and Ouro Negro cultivars stand out for resistance. Under field conditions, the UFLA 3 isolate discriminates well the lines, while, under greenhouse conditions, UFLA 26 and UFLA 92 are the most aggressive isolates. Furthermore, according to the genetic study, most of the observed variation can be attributed to horizontal resistance, although a small part is associated with vertical resistance. RESUMO - O objetivo deste trabalho foi avaliar a reação de linhagens de feijoeiro (Phaseolus vulgaris) ao fungo Sclerotinia sclerotiorum, a agressividade dos isolados, e a herança de resistência ao mofo-branco, em duas condições ambientais. Os experimentos foram realizados em condições de campo e casa de vegetação. Em cada um deles, quatro isolados foram inoculados em 14 linhagens de feijoeiro-comum pelo método de inoculação ?straw test? e a severidade nas plantas foi avaliada. Não se identificaram linhagens de feijão-comum com alto nível de resistência ao mofo-branco, e a maioria delas mostrou-se moderadamente resistente ao patógeno. Em geral, as cultivares BRS Campeiro, BRS Radiante, BRSMG Talismã e Ouro Negro destacam-se quanto à resistência. Na condição de campo, o isolado UFLA 3 discrimina bem as linhagens, enquanto, na casa de vegetação, UFLA 26 e UFLA 92 são os isolados mais agressivos. Além disso, de acordo com o estudo genético, a maior parte da variação encontrada pode ser atribuída à resistência horizontal, embora uma pequena parte esteja associada à resistência vertical.
