Color Variations in the Canes oj the Blackberry 



Not only is the leaf a guide to the kind oJ Jruit which a 



plant will produce, but in many cases the stem or cane gives a 



reliable indication. With most berries it is the rule that the light stalk 



will produce the lightest color berry — and the darker the stalk 



the darker the berry. From the variations above it 



will be seen that Mr. Burbank was able to 



select joT lightness of color even fee/ore 



he used the leaves as an indi' 



cation to size and form.
