ARIZALETA, M; MONTILLA, J  e  PARES, J. Effect of seeds storage coffe (Coffea arabica L. var. Catuai amarillo) on emergence. Rev. Fac. Agron. [online]. 2005, vol.22, n.3, pp.205-213. ISSN 0378-7818.

In order to determining the effect of storage on coffee seeds the germination, for it stored seeds in sisal and white polyethylene packings during 0, 2, 4, 6, 8 and 10 months in three conditions: condition 1 (20°C and 78% HR); condition 2 (26°C and 65% HR) and condition 3 (10°C and 55 % HR), When finalizing the test could be appreciated as the period of storage had a significant effect on the germination, since as passed the time, a well-known reduction of the percentage of germination in the lots of seeds took place significantly, being in addition affected so much by the conditions of storage like by the type of used packing. Nevertheless, during the first 6 months of storage in conditions 1 and 2, the percentage of germination was relatively high (91.1% and 92.2% respectively), in comparison to the condition 3 that presented/displayed 5.8% as of the fourth month of storage. When finalizing the test the percentage of germination were of 58.1%; 31.4% and 2.2% for conditions 1, 2, and 3 respectively. Being the condition of 20°C with 78% HR and the most favorable packing of sisal to maintain the physiological quality of the seed by a period of up to ten months.
