البرتغالية. The production of good quality seedlings becomes essential strategy for those who wish to become production that is more competitive. To induce dormancy breaking and germination and emergence of these, the imbibing of natural acid in seeds can be an alternative for the optimization of this process. The aim of this study is to evaluate the dormancy breaking in Anonna seeds squamosa immersed in different natural acid in times through the lemon juice Rangpur (Citrus limonia Osbeck). This work is being conducted in Biotecnogia laboratory greenhouse at the Federal Institute Goiano campus Urutaà where the seeds were soaked in lemon juice Rangpur (C. limonia) in five different times, each time constituting a treatment: seeds without soaking in lemon groove variety Cravo '(T1); soaked for 8 hours (T2); soaked for 16 hours (T3); soaked for 24 hours (T4); soaked for 32 hours (T5). The seeds were sown in plastic boxes with dimensions 40 x 27 x 10 cm, containing washed sand substrate, 2 cm deep in spacing of 2 x 2 cm. The germination percentage data were determined up to 45 days after sowing (DAS), and survival to 73 (DAS). After 73 DAS were evaluated after 73 days of sowing, they were evaluated; germination and survival; emergence speed index (EVI); total length of seedlings; shoot length of seedlings and radicle length (cm); Stem diameter (mm); pair of leaf number (MPN); total fresh mass changes (MFT); dry matter of shoot and radicle (g). There was not statistical diseases among treatments. T4 treatment in comparison to others on the numerical difference CTM, NPF, DC and CPA.Â
