Qualidade fisiológica de sementes de sabiá (Mimosa caesalpiniaefolia Benth) tratadas com extratos vegetais

The objective of this study was to evaluate the efficiency of plant extracts of Allamanda Blanchetti L), Momordica charantia L. essential oil of anise ( Pimpinella anisum L.) on mycoflora and seed physiology Mimosa caesalpiniaefolia Benth. The experimental design to test germination was completely randomized with five treatments, distributed in four replicates of fifty seeds per treatment. The seeds were placed in paper rolls germitest previously sterilized and germinated in a germination chamber at 27 ° C ± 2 ° C. The vigor tests consisted of the first count and germination speed index. Treatment with essential oils and extracts promoted higher mean germination when compared with the control. Extracts of A. blanchetti, M. charantia and essential oil of fennel ( Pimpinella anisum L.) can be considered alternatives for the replacement of chemical fungicide seed in the preventive treatment of M. caesalpiniaefolia
