DESENVOLVIMENTO DE Coriandrum sativum CV.VERDÃO SOB DIFERENTES NÍVEIS DE INFESTAÇÃO DE Rotylenchulus sp

Abstract

The coriander Coriandrum sativum L. is a imperative spice in the brazilian cookery, being one of the main vegetables of the Northeast region. In the coriander culture, the nematode Rotylenchulus reniformis has been causing significative damage in the production. The goal of the paper was to evaluate the development of coriander in different levels of Rotylenchulus reniformis infestation. Were realized collections of soil infested by Rotylenchulus reniformis, where it was made the extraction, quantification and elaboration of the levels of infestation to each treatment. The experiment was conducted in completely randomized design and the treatment were constituted of 700, 1400, 2100, 2800, 3500 and 4200 levels of infestation by Rotylenchulus reniformis, with six repetitions, and with five seeds per vase. The evaluations were made 45 days after the planting and are substantiated in the dry mass of the aerial part and the dry mass of the root system. With the growth of the infestation level, it was noticed a decrease in the dry mass of the aerial part and a raise in the root system.
