TERRY ALFONSO, Elein; RUIZ PADRON, Josefa; TEJEDA PERAZA, Tamara  y  REYNALDO ESCOBAR, Inés. Agrobiologycal effectiveness of Pectimorf^® bioactive product on radish (Raphanus sativus L.) crop. cultrop [online]. 2014, vol.35, n.2, pp.105-111. ISSN 0258-5936.

The present work was developed in the experimental area of the National Institute of Agricultural Sciences (INCA), with the objective to evaluate the answer of radish crop with the application of Pectimorf^® bioactive product. The objective was to study of effect of bioproduct on seeds germination as well as on growth, development and yield of plants; different dilutions were studied of 1-100 for the evaluation of seeds germination answer as well as doses of 0,1-1 10 mL.L^-1 and imbibition times of 30 minutes, one and eight hours for the experiment in field. Were carried out different evaluation in relation with some germination variables as percentage, index of germination speed as well as large of hypocotyl and the radicle. In the field experiment were evaluating plant height, diameter of shoot, fresh mass of fruits and yield for surface. The results showed the effectiveness of Pectimorf^® bioactive product in the seeds germination phase, being stimulated this process with the dose of 10 mL.L^-1 and 30 minutes of imbibition. In the case of crop stimulus on growth, development and yield, the best result was obtained with the dose of 5 mg.L^-1 and one hour of imbibition time, being overcome the yield in 41 % with regard to the production test.
