The aims of this work were principally two-fold: first, to show that cyclic voltammetry is a simple, cheap and practical method for determining antioxidants in citrus fruit juices; second, to evaluate vitamin C in four species of citrus fruits. Two are known world wide, the lemon, Citrus limon (L.) Burm.f., and the lime, Citrus aurantiifolia (Christm.) Swingle, and two are principally but not e...

Many species of the so-called exotic plants coexist with native in a balanced way, but others thrive very quickly and escape human control, becoming harmful—these are called invasive alien species. In addition to overcoming geographic barriers, these can defeat biotic abiotic maintaining stable populations. Ailanthus altissima is no exception; it disseminated worldwide considered high risk due ...

We determined if frequency of application of irrigation water plus fertilizer in solution (fertigation) could modify root and shoot growth along with growth per unit nitrogen (N) and water uptake of seedlings of the citrus rootstock Swingle citrumelo growing in a greenhouse. In the first experiment, all plants received the same amount of water with sufficient fertilizer N but in three irrigatio...

Abstract Background The insect vector of Huanglongbing, Diaphorina citri Kuwayama, 1908 (Hemiptera: Lividae) was detected in Ecuador 2013 and its main parasitoid Tamarixia radiata (Waterston, 1922) (Hymenoptera: Eulophidae) reported for the first time 2017. In citrus production region Manabí province, Ecuador, D . T were on Murraya paniculata L. 2016 2018, respectively. D. found infesting Citru...

Investigation of the chemical constituents from the fruits of Citrus medica L. var. sarcodactylis Swingle has led to the characterization of a new sesquiterpene 1 along with thirty-two known compounds. The structure of 1 was established on the basis of 2D NMR spectroscopic and mass spectrometric analyses, and the known compounds were identified by comparison of their physical and spectroscopic ...
