<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D">Brian : Fruit shape and color are affected by growing climate/region.. Red Delicious fruits grown in warmer climate are likely to be round or flat while those
in northern regions tend to be oblong (so called type or is it typy like shiny). I recall from memory that an extension publication showed that apples from North Carolina were more round and flat while those from either NY or Washington? were oblong. This
is likely to be regulated by hormones since you can make fruits more oblong shape with Promalin (GA4 +GA7 + 6-BA). Skin finish is also affected by humidity and temperature. High humidity and high temperature tend to make fruit color more dull while low humidity
and cooler daytime temperature tend to make fruit color more shiny with smoother finish.

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif">I have two orchard locations, one in a valley and a nearby one on a hilltop. I’m mystified by a “dry skin” quality in the valley farm.
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif">I graded Liberty apples last night and the differences between the two sites were dramatic. Hilltop—smooth, satiny finish; dark color; long “red delicious” shape. Valley—shiny
finish; bright color; spherical shape. Jonagolds and Idareds from the valley have an almost papery skin; much smoother/waxier from the hilltop.<o:p></o:p></span></p>
