“…The cultivation of Cucurbita spp. has an important role regarding economic and social aspects as well as in human nutrition, due to its cooking versatility and nutritional value, animal feed, industrialisation and use for medicinal and ornamental purposes (CAMURÇA-VASCONCELOS et al, 2005;BOITEUX et al, 2007;FERREIRA, 2008;AMBRÓSIO et al, 2012).…”

-In order to rescue Cucurbita spp. germplasm from family farming in the state of Rio Grande do Norte, to quantify the phenotypic variability and identify the main species grown, 17 expeditions were organised to collect accessions in the municipalities of Baraúna, Rio do Fogo and Touros (major fruit suppliers to the state trade) and in eight more municipalities in different regions of the state (Apodi, Caraúbas, Ceará Mirim, Cerro Corá, Currais Novos, João Câmara, Lagoa Nova and Macaíba). Each collected accession consisted of a fruit or about 20 seeds provided directly by the farmer. All accessions were identified according to botanical species, and packaging procedures, identification and seed storage in the cold for preservation were performed. A sample of collected accessions, consisting of fruit and a small number of accessions obtained as C. moschata seeds, was multiplied using self-fertilisation of plants. Plants and fruits were characterised preliminarily with the aid of morphological descriptors. Accessions were rescued in all visited municipalities -112 of C. moschata and 50 of C. maxima. There was a predominance of C. moschata species cultivation, and great variability was found in various plant and fruit descriptors in the accessions characterised.Keywords: C. moschata. C. maxima.

RESGATE DE GERMOPLASMA DE Cucurbita spp. NO RIO GRANDE DO NORTERESUMO -Com objetivo de resgatar germoplasma de Cucurbita spp. da agricultura familiar do estado do Rio Grande do Norte, quantificar a variabilidade fenotípica e identificar as principais espécies cultivadas, foram organizadas 17 expedições para coleta de acessos, nos municípios de Baraúna, Rio do Fogo e Touros (principais fornecedores de frutos para o comercio estadual) e de mais oito municípios de diferentes microrregiões do Estado (Apodi, Caraúbas, Ceará Mirim, Cerro Corá, Currais Novos, João Câmara, Lagoa Nova e Macaíba). Cada acesso coletado foi composto por um fruto ou aproximadamente vinte sementes fornecidas pelo próprio agricultor. Todos os acessos foram identificados quanto à espécie botânica e realizados os procedimentos de acondicionamento, identificação e armazenamento das sementes em câmara fria para preservação do material. Uma amostra dos acessos coletados como frutos e uma pequena parte dos acessos obtidos como sementes da espécie C. moschata foram multiplicados usando-se autofecundação das plantas. Plantas e frutos foram caracterizados preliminarmente com auxílio de descritores morfológicos. Resgatou-se acessos em todos os municípios visitados, sendo 112 de C. moschata e 50 de C. maxima. Verificou-se predominância do cultivo da espécie C. moschata bem como constatou-se grande variabilidade para vários descritores de planta e fruto nos acessos que foram caracterizados.Palavras-chave: C. moschata. C. maxima. Coleta de acessos. Variabilidade.

Vitamin A (VA) is an essential nutrient often lacking in the diets of people in developing countries. Accurate biomarkers of VA status are vital to inform public health policy and monitor interventions. The relative dose-response (RDR) and modified-RDR (MRDR) tests are semi-quantitative screening tests for VA deficiency that have been used in Demographic and Health Surveys and VA intervention studies. A systematic review and meta-analysis of sensitivity and specificity were conducted to summarize the physiological evidence to support the RDR tests as methods to assess VA status and investigate the impact of different pathological and physiological states on the tests. A total of 190 studies were screened for inclusion, with 21 studies comparing the RDR tests with the gold-standard biomarker, liver VA concentration (68% and 80% sensitivity and 85% and 69% specificity for the RDR and MRDR, respectively). Nearly all studies with VA interventions in VA-deficient populations demonstrated a response of the tests to VA intake that would be expected to improve VA status. The impacts of chronic liver disease, protein malnutrition, age, pregnancy and lactation, infection and inflammation, and various other conditions were examined in 51 studies. The RDR and MRDR tests were reported to have been used in 39 observational studies, and the MRDR has been used in at least 6 national micronutrient surveys. The RDR and MRDR are sensitive tests for determining population VA status and assessing VA interventions. Although they are robust to most physiological and pathological states, caution may be warranted when using the tests in neonates, individuals with chronic liver disease, and those with protein or iron malnutrition. Research on further improvements to the tests to increase accessibility, such as sampling breast milk instead of blood or using intramuscular doses in subjects with malabsorption, will allow wider adoption. This review was registered with PROSPERO as CRD42019124180.
