Size-resolved long-term measurements of atmospheric aerosol and cloud condensation nuclei (CCN) concentrations and hygroscopicity were conducted at the remote Amazon Tall Tower Observatory (ATTO) in the central Amazon Basin over a 1-year period and full seasonal cycle (March 2014?February 2015). The measurements provide a climatology of CCN properties characteristic of a remote central Amazonian rain forest site. The CCN measurements were continuously cycled through 10 levels of supersaturation (S = 0.11 to 1.10 %) and span the aerosol particle size range from 20 to . The mean critical diameters of CCN activation range from at The particle hygroscopicity exhibits a pronounced size dependence with lower values for the Aitken mode , higher values for the accumulation mode , and an overall mean value of, consistent with high fractions of organic aerosol. The hygroscopicity parameter, exhibits remarkably little temporal variability: no pronounced diurnal cycles, only weak seasonal trends, and few short-term variations during long-range transport events. In contrast, the CCN number concentrations exhibit a pronounced seasonal cycle, tracking the pollution-related seasonality in total aerosol concentration. We find that the variability in the CCN concentrations in the central Amazon is mostly driven by aerosol particle number concentration and size distribution, while variations in aerosol hygroscopicity and chemical composition matter only during a few episodes. For modeling purposes, we compare different approaches of predicting CCN number concentration and present a novel parametrization, which allows accurate CCN predictions based on a small set of input data.

Cultivars tolerant to low temperature during the germination and emergence stages and carriers of the grain qualitystandards demanded by consumers are needed to increase the success of irrigated common bean in Southern MinasGerais State. To study the genetic mechanisms controlling these traits and assess the possibility of generating thedesirable materials, a diallel cross involving ten cultivars including introductions and pure lines from the breedingprogram of ESAL was carried out. Speed of germination of the F2 generation from the crosses was assessedunder laboratory conditions at 12 °C. The diallel analysis was carried out using Griffing's method IV (1956)and predictions of the cross potential were made by the methodology developed by Jinks & Pooni (1986). Theresults indicated that the parents differed in germination speed at low temperatures with `Small White', `A-488'and `Rio Vermelho' being the most tolerant and 'Carioca', 'ESAL 609' and 'ESAL 591' the most sensitive. Noeffect of the reciprocal crosses was observed either for germination percentage or germination speed. The parents`A-488', `Small White' and `Rio Vermelho' showed the greatest general combining ability. Additive genetic effectspredominated for both traits. Our results suggest that cold tolerance can be bred successfully into commerciallyacceptable cultivars. |
