Plates I and II show in color four stages in ripening, which are 

 referred to later in this bulletin as green, i.e., with no red present (A) ; 

 turning, i.e., mostly green, with a trace of color at the style end (B) ; 

 pink, i. e., slightly colored over most of the fruit, with little or no 

 green except at the stem end, but not yet a good full red (O); and' 

 red ripe, i. e., completely mature as far as color change is concerned (D). 



Material for analysis was obtained by tagging blossoms (other than 

 those of the "crown hand") 3 soon after opening and then collecting 

 tomatoes at the different stages in numbers large enough for sampling. 

 An attempt was made to pick all the tagged fruit from an entire row 

 in order to eliminate the error that possibly otherwise might have 

 occurred of unconsciously selecting large or small fruit. Samples 

 were taken at the end of the second, third, fourth, fifth, and sixth 

 weeks, and after the tomatoes had barely started to color (designated 

 as turning), and finally when fully colored or ripe. At the time of 

 carrying on the work the weather conditions were such that eight 

 weeks were required to bring the tomato to maturity (red ripeness). 



> Growers are accustomed to refer to all the fruit developing from a single inflorescence as a "hand." 

 The "crown hand" is the lowest inflorescence on the stem. It frequently fails to set fruit.
