Peach "Buttons" 



A certain proportion of the peaches on any variety may cling to 

 the tree but remain small and undeveloped following a cold period 

 in late winter and early spring. This is apparently due to injury to the 

 stem of the bud or fruit or to the twig at the point of attachment of 

 the fruit, to defective pollination, or both. 



The J. H. Hale variety frequently produces such specimens but 

 whether because of weather injuries or incomplete floral development 

 is yet to be determined. 



Such cases should not be confused with "little peach" however. 



Factors Which Determine Color of Healthy Fruit 



The red coloring on peaches of the same variety is due to maturity 

 and exposure to sunlight, with temperature a possible factor. 



Abnormal purplish-red colorings often occur as a result of spray 

 burning, leaf curl and other injuries. 



Following winter injury peaches may develop a red spotting and 

 blotching practically identical with yellows.
