VARGAS-CALVO, Alfonso  and  VALLE-RUIZ, Henry. Efecto de dos tipos de fundas sobre el fruto de banano (Musa AAA). Agron. Mesoam [online]. 2011, vol.22, n.1, pp.81-89. ISSN 2215-3608.

Effect of two banana (Musa AAA) bunch covers on fruit quality. The objective of this study consisted to determine the effect of two protective covers of the banana (Musa AA) bunch. The study was carried out in two climatic seasons (adverse and favorable) at the Caribbean of Costa Rica. The covers compared were: 1-blue Santa Lucia (bifentrin 0.1%, polyethylene 12.7 μ thickness, with perforations of 4 mm and 86.4 cm wide) and 2- transparent photosensitive (bifentrin 0,1%, 20.3 μ, 4 mm holes and 86.4 cm wide). The bunch weight and the thickness and length of the central fruit of the outer row in the second, fourth and sixth hands did not differ (P> 0.0556) between bunch covers. There were no differences between bunch covers in bunch appearance (P> 0.4699) or in the peel firmness in grade 1 of maturation (P> 0.6268). For fruit color parameters, only L* showed a greater (P= 0.0109) value (56.48) in the transparent photosensitive bunch cover relative to the blue Santa Lucia, whereas the other two related variables (a* and b*) did not differ between treatments (P>0.1011). The increment of 7.6 μ in the polythene thickness of the transparent photosensitive with respect to the blue Santa Lucia bunch covers did not result in increased production or in improvement of bunch and fruit appearance.
