The total carbohydrate content in the petals varied thought the evaluation period,
decreasing after 2 days, possibly because of on increase in the respiration rate (I. Figueroa
and M. Colinas, 2005), in addition after 5 days all concentration GA had high CH content
because of the lower in the respiration rate (I. Figueroa, T. Colinas, 2005) at day 10 CH
began to decrease exhausting the substrate. These results agree with Figueroa and Colinas
(2005) (fig 1, a, b, c, d).
