Abstract(s)
Os porta-enxertos predominantes hoje na bacia do Mediterrâneo são as citranjeiras, sobretudo a ‘Carrizo’. A laranjeira ‘Gou Tou’ é considerada um híbrido natural de laranjeira azeda, e é um dos porta-enxertos mais comuns na China. Este híbrido pode contribuir para a diversificação dos porta-enxertos usados em Portugal e em países vizinhos. Parece ser tolerante à Tristeza, cresce bem em solos calcários, é tolerante à salinidade e à seca. O seu efeito sobre a produtividade e a qualidade do fruto devem ser estudados.

The citrus tree 'Gou Tou' is considered a natural hybrid of sour orange and is one of the most common rootstocks in China. This hybrid can contribute to the diversification of the rootstocks used in Portugal and in neighboring countries. It seems to be tolerant to Tristeza disease, it grows well on calcareous soils, it is tolerant to salinity and drought. Its effect on fruit yield and quality must be studied.
