Evaluate possible  alterations in the development, anatomy  and  quality  of fruits from 'Maxi 
Gala' and 'Fuji Suprema' apple plants treated with Metamitrom (MM) and Benzyladenine (BA) alone 
or in combination, applied at different stages of fruit development in the Midwestern region of the 
state of Santa Catarina. Study  Design:  The  experiment  was  arranged  in  a  randomized  block  design  with  five  replicates. 
Place and duration of Study: The experiment was carried out in the municipality of Caçador-SC, 
Brazil, during the growing season of 2016/2017.  Methodology:  Two  products,  BA  (with hormonal  action)  and  MM (photosynthesis  inhibitor)  were 
applied individually or in a tank mix in post-flowering periods (in fruits of 5-10 mm and 15-20 mm in 
equatorial diameter), which were compared with plants with no thinning and manual thinning of both 
cultivars. Treatments were as follows: Control (no thinning) MM, BA, MM + BA (in fruits of 5-10 mm 
in  diameter);  MM,  BA,  MM  +  BA,  manual  thinning  (in  fruits  of  15-20  mm  in  diameter). 
 The phenological  stage  of  F2  (Full  flowering  (FF)  was  observed  on  September  28,  2016  for  both 
cultivars. Evaluations of the anatomical characteristics of fruits at the time of harvest did not show 
any alteration in cell size (mean cell area - &#956;m 2 ) and cell density (number of cells per fruit section 
area); the mean fruit mass was higher in MM 350 mg L -1 (5-10 mm), MM 350 mg L
