On containers or display racks from which apples are sold in retail quantities, the variety, grade, and minimum size shall be clearly indicated, but the provision of section 234 of this title as to markings of name and address of the packer or person by whose authority the apples were packed and the state where grown shall not apply to apples in such containers or display racks. Nothing in this chapter shall be construed to prevent a grower from selling apples on his or her premises in bulk or in open packages without such marking.
