Color Variations in the Canes of the Blackberry 



Not only is the leaf a guide to the kind of fruit 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 for lightness of color even before 

 he used the leaves as an indi- 

 cation to size and form.
