    A floricultura tropical tem se expandido na última década devido a uma crescente tendência do mercado mundial em consumir flores exóticas, coloridas, belas e duráveis. Zingiberaceae é a maior da ordem Zingiberales. Dentro desta família, podemos mencionar Alpinia zerumbet, muito cultivada pela beleza de suas flores. Objetivou-se avaliar o período de floração de Alpinia zerumbet de janeiro de 2010 a dezembro de 2012, cultivada na coleção do horto de plantas medicinais da Embrapa Amazônia Oriental. A avaliação fenológica foi realizada diariamente, pelo período da manhã, utilizando uma planilha de campo para o acompanhamento de seu desenvolvimento, Os dados obtidos de floração da espécie Alpinia zerumbet demonstram que houve floração em todos os meses do ano, exceto nos meses de julho e dezembro. Concluise que com base nos dados obtidos através da fenologia d a espécie Alpinia zerumbet.,esta apresentou floração em todo o período de avaliação o que irá proporcionar uma coleta bem distribuída de flores durante todo o an

    For artificial insemination, it is essential to use frozen semen, however the freezing process causes deleterious changes to the structure and integrity of sperm membranes that compromise the function of sperm. To avoid this cellular damage, extenders and suitable substrates must be used to recover the highest possible number of viable cells post-thaw. To this end, in the first experiment, we evaluated three different extenders: TES-TRIS, which is widely used for buffaloes; and an extender composed of powdered coconut water-based (ACP-112®) with or without milk (ACP-112®-milk) for buffalo semen freezing. In the second experiment, we evaluated the effect of Lippia origanoides oil extract on protecting buffalo sperm against cryoinjury arising from freezing semen. Semen was collected from ten buffalo bulls (10 ejaculates/bull) and diluted in TES-TRIS (control), ACP-112® or ACP-112®-Milk in the first experiment. In the second experiment, the samples were diluted in the diluent with the best results for sperm quality obtained in experiment I, and 2.5 µg mL-1, 5 µg mL-1 or 10 µg mL-1 of the plant extract was added to treatments; and a control group containing only the diluent was also included. The fresh semen was analyzed for conventional features such as motility, concentration, morphology and viability. After thawing, the samples were evaluated again for motility, vigor and supra-vital staining, and then, were performed the of thermal-resistance test, hypoosmotic test and evaluated sperm membrane integrity with the fluorescent probes PI, FITC-PSA and JC-1 using flow cytometry. The data were submitted to ANOVA, and the results were compared by Tukey?s test at a significance of 5%. In the first experiment, the extender TES-TRIS showed better results for the various characteristics evaluated compared to ACP-112® and ACP-112®-Milk (P 0.05). Based on these data, we demonstrated the beneficial effects of TES-TRIS for post-thaw buffalo sperm quality; however, no protective effect was observed for buffalo sperm cryopreserved with the different tested concentrations of Lippia origanoides extract oil
