Compared to the effect
on plantains, 20% CO
treatment delayed the decline in the chlorophyll florescence
values and in the mRNA levels
of a gene coding small subunit of Rubisco (SSU), and postponed the disruption of the ultrastructure of chloroplast in the
peel tissue of bananas, indicating that the senescence of the green cells in the exocarp layer was delayed by 20% CO
,
to more extent in bananas than in plantains. High CO
reduced the ethylene production and the expression of the related
