Oil palm (Elaeis guineensis Jacq.) apparently tolerates long-term waterlogging and numerous pneumatophores are evident morphological adaptation. The number of pneumatophores per plant is, however, quite variable. Thus we hypothesized that a higher number of pneumatophores may attenuate the stress effects on root system growth and induce higher tolerance to long-term waterlogging in oil palm seedlings. To test this hypothesis we compared morphological and physiological traits in well-watered (control) and waterlogged plants with 2?10, 30?40, 60?70, and 90?120 pneumatophores after ca. 77 days of waterlogging. Plant height was similar between control and waterlogged plants with 90?120 pneumatophores, but it was 21% lower in plants with 2?10 pneumatophores than in control. The stem diameter and bulb diameter and biomass were 16, 20 and 42% higher in waterlogged plants than in control, independent of number of pneumatophores. Similar number of leaves and leaflets were observed regardless of watering regime and pneumatophore number, but total leaflet area and leaflet biomass were higher in plants with 90?120 pneumatophores than in other plants. Root system biomass was remarkably decreased in waterlogged plants; however, such decreases were more expressive in plants with 2?10 pneumatophores. Leaf water potential, leaf gas exchange and chlorophyll fluorescence were unaffected by waterlogging. Thus, we conclude that waterlogging causes few changes in seedlings? above-ground morphology but remarkably affects root system development, mainly in those plants with lower number of pneumatophores. Regardless of pneumatophores, the stressed oil palm seedlings were able to adjust their leaf water status and gas exchange to cope properly with the imposed waterlogging.

ABSTRACT: This study evaluated if the milk ring test (MRT) used to the brucellosis diagnostic at dairy herd level can be done in milk samples with conservative (Bronopol®) collected to the somatic cell count (SCC) that is used to mastitis monitoring. It were analyzed 38 bulk tank milk samples (BTMS) from 19 dairy herds artisanal cheese producers and 36 BTMS from a brucellosis free dairy herd, used as negative control (NC) and positive control (PC), when was added serum from vaccinated animals. The milk samples were collected in two different bottles (with or without Bronopol®). All the 38 BTMS from artisanal cheese producers (samples with and without Bronopol®) were non-reagent to MRT, as all NC. All PC were reagent to MRT, without interference of Bronopol®. Results showed that the milk sample used to SCC presented the proportion of agreement of results in all milk samples (100%), that is, false positive and false negative results were not observed. Results indicated that Bronopol® did not interfere with the color in the time of MRT reading suggesting that the same milk samples could be used to monitoring mastitis and brucellosis. RESUMO: O objetivo deste estudo foi avaliar se o teste do anel do leite (TAL), utilizado para o diagnóstico da brucelose em nível de rebanho leiteiro, pode ser realizado em amostras de leite com conservador (Bronopol®) coletado para contagem de células somáticas (CCS) que é utilizado para monitoramento de mastite. Foram analisadas 38 amostras de leite de tanques de expansão (ALTE) de 19 rebanhos leiteiros produtores de queijo artesanal e 36 ALTE de rebanho leiteiro livre de brucelose, utilizadas como controle negativo (CN) e controle positivo (CP), quando foi adicionado soro de animais vacinados. As amostras de leite foram coletadas em dois frascos diferentes (com e sem Bronopol®). Todos as 38 ALTE de produtores artesanais de queijo (amostras com e sem Bronopol®) foram não reagentes ao TAL, como todos os CN. Todos os CP foram reagentes ao TAL, sem interferência do Bronopol®. Os resultados mostraram que a amostra de leite utilizada para CCS apresentaram a proporção de concordância dos resultados em todas as amostras de leite (100%), ou seja, não foram observados resultados falso-positivos e falso-negativos. Os resultados indicam que o Bronopol® não interferiu na cor no momento da leitura do TAL, sugerindo que as mesmas amostras de leite poderiam ser usadas para monitorar mastite e brucelose MenosABSTRACT: This study evaluated if the milk ring test (MRT) used to the brucellosis diagnostic at dairy herd level can be done in milk samples with conservative (Bronopol®) collected to the somatic cell count (SCC) that is used to mastitis monitoring.
