ALVES, Charline Zaratin; CANDIDO, Ana Carina da Silva; OLIVEIRA, Naiane Cristina de  and  LOURENCO, Flávia Mendes dos Santos. Germination test in Cucumis metuliferus E. Mey seeds. Cienc. Rural [online]. 2014, vol.44, n.2, pp.228-234. ISSN 0103-8478.

The kiwano (Cucumis metuliferus E. Mey) is a cop of wide geographical distribution, with a significant increase in relation to marketing worldwide due not only to his life being too long at room temperature, as well as to the constant search market consumer for exotic products. Thus, demand and marketing of its seeds are increasing, creating the need for the establishment of state and federal standards and the development of appropriate methodologies for evaluating the quality of them. Thus, the objective of this study was to determine the methodology for the substrate, temperature and time count for the germination test on Kiwano seeds. The evaluations consisted of four substrates: paper roll, on paper, in sand and on sand at four temperatures: 20, 25 e 30°C constant and 20-30°C alternating. The effect of substrate and temperature on seed performance was evaluated using germination, speed index and mean germination time. The experiment was conducted in a completely randomized design with treatments arranged in a factorial 4x4 (substrates x temperatures) with four replications. The test germination in seeds of kiwano should be done on the paper roll at constant temperature of 25°C or alternating 20-30°C, with counting starting and ending in the fifth and tenth day, respectively.

Keywords : kiwano; substrate; temperature.
