Performance of ‘Marrs’ Early Orange on Eleven Rootstocks in South Texas1

Abstract

Abstract ‘Marrs’ early orange trees, Citrus sinensis (L.) Osbeck, on Swingle citrumelo rootstock were more productive than trees on Texas sour orange, Cleopatra mandarin, and 8 other rootstocks. Fruit from trees on Swingle was large, but had a Brix 0.8% lower than fruit from trees on Texas sour orange, while the acid content was similar. Leaf concentration of 12 elements was affected by rootstocks, especially by Chinese box-orange.
