Mature storage roots from two clones, Amarela de Carandaí and Roxa de Viçosa, stored at 10°C showed only slight symptoms of chilling injury after 28 days. At 5°C both clones were moderately injured after 14 days and extremely injured after 28 days.
Crescimento e produção de cumarina em plantas de chambá (Justicia pectoralis Jacq.) tratadas com isoterápico
Palavras-chave: Justicia pectoralis, homeopatia, dinamizaçõesABSTRACT: Growth and production of coumarin in the plants of chambá (Justicia pectoralis Jacq.) treated with isoterapic. The studied aimed to evaluate the responses to dynamizations of Justicia isoterapic in growth and coumarin production in Justicia pectoralis. The studies were carried out at the Universidade Federal de Viçosa. The statistical design was completely randomized, with four replicates and six treatments, 24 experimental plots, one plant per pot. The treatment were dynamizations 3CH, 6CH, 12CH, 18CH, 24CH and 30CH Justicia isoterapic. The applications of the treatments begun are planting seedlings, the aerial part being sprayed, at weekly intervals. After four months of planting, the plants were harvested. Were evaluated fresh and dry matter of stem and leaves, fresh and dry matter of inflorecense, and fresh and dry matter total. Were weighed samples on 200 mg of leaves and stems of dried plants. The samples were properly stored at quimical analyses. The quantification of coumarin (1-2 benzopyrone) in the samples was done in High Resolution Liquid Chromatography. The fresh matter of leaves and stems, the fresh matter total and a production of coumarin varied as a function of dynamization of isoterapic. The results confirm the effect of homeopathics preparations in the plants demonstrating that homeopathy in vegetables even in the Equality Law has potential effect.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
