ARISTIZABAL L, Manuel. Time of storage of corm age and its effect on the growth and production of the plantain (Musa AAB) Dominico Harton. Acta Agron. [online]. 2013, vol.62, n.4, pp.304-311. ISSN 0120-2812.

To evaluate the effect of the time of storage of propagation material on growth and production of plantain, corms were extracted from healthy plants and were peeled to eliminate roots and necrosed tissue. The half of themwas submerged during 60 minutes in a solution on basis of 15g of Carbofuran an 20g of Manzate in 10 L of water, after which, all of the corms, chemically treated and non-treated, were disposed on de soiland covered with plantain fresh leaves.Each week, during a period of 6 weeks, the required quantity of corms was taken to be planted at 3m between rows and 2m between plants in an experimental design of split plots, with four replicates and 10 plants per replication. At flowering registers of plant height, pseudostem diameter, number of functional leaves and the youngest spotted leaf were made; at harvest bunch weight was registered and the average finger weight was calculated. It was found thatstorage of the corm reduces plant growth but not affect the Sigatokas’ severity; that bunch and finger weights are severe and significantly reduced and that corm preventive treatment has positive effects on plant growth and production but not reduces the damage caused by propagation material storage.
