The "Guoguang" apple tree also has a phenomenon similar to what you said. When the apple is green, it begins to appear brown stripes on the peel. Stripes don't grow with the growth of apples, so they begin to crack slowly, and apples don't grow big.

Later, I became independent and felt that the next year was effective. I don't know if you believe it or not, but I give it acupuncture. That is to say, I bought more than 100 large needles 6-7 cm long, shaped them at the fork of the tree, and took them off after about half a month. I only did it once. There seems to be no such spots and stripes in the next summer, only occasionally. When I was near early autumn, I reduced my books because my house was to be rebuilt.
