Utilização de rizobactérias e micorrizas na produção de mudas de maracujá

Abstract

Passion fruit is a tropical fruit seasoning used for the manufacture of juices pulps and ices cream, easy acceptance due to the characteristic of aroma and flavor, and of proven medicinal properties. In the search of plants of passion fruit high production, they leave of the principle of the necessity of the organic seasoning use and chemical, that finished for raising the production cost, transferred to test it mycorrhizal fungi arbuscular and for production of seedlings. The present work objectified to study the effect of the association of mycorrhizal symbiosis and promotional rhizobacterias of the growth for the production of changes of plants of passion fruit in the State of Alagoas. The present investigation was conducted on laboratory conditions (Laboratory of Microbiology) and green house of the Center of Agrarian Sciences of the UFAL. The experiment had duration of 90 days, the experimental was in a randomized complete designer delineation complete with inoculation (200 sporos/plant) of plants with mycorrhizal fungi associates and witness, associates and not, with rhizobacterias, seven repetitions each treatment. The analysis of the data with Scutellospora heterogama and for Glomus etunicatum had resulted in better leaf number and size of plants, and also when associates to Isolated the 15. For rhizobacterias, suspensions of bacteria from isolated out epiphytes and on epiphytes cultivated in half BD had been prepared (Potato), being the changes of plants of passion fruit kept 21 days in green house of production of changes, and after this period, had been evaluated cool substance of the roots, aerial and total part, beyond levels of N, P, K, Ca, Mg that had kept the levels balanced throughout the experiments. G. albida + I15, S. heterogama + I15 and G. etunicatum + I09 had also provided to improvement in leaf number and height of plants. The results suggest that the plants of passion fruit are not a species highly dependent of mycorrhizal fungi arbuscular. The results showed that use of isolated the 02, 09, 13, 15 had not effect in the production of seedlings of passion fruit, and that the FMA use can contribute for a significant improvement in the production of these seedlings. This research can to influence actions that aim at the production of seedlings with quality and in satisfactory number with the use of rhizobacteria and FMA.
