174 STU])IES IN INDIAN SUGARCANE SEEDLINGS 



LENCiTH OF LEAF AND SUCROSE. 



Correlation 2. 



This correlation calls for little remark. The length of leaf was obtained 

 in exactly the same manner as the leaf width, in fact the same shoots were 

 measured in the two cases. In all the classes examined, exceptijig one, there 

 is a distinct negative correlation between leaf length and sucrose in the juice. 

 The exception is the cross between Vellai and Saccharum Nnrenga, again a 

 series of crossed seedlings. The absence of divisions into four classes in the 

 smaller series is due to great irregularities in these, the full lists of seedlings 

 arranged according to length of leaf, not falling readily into normal frequency 

 -curves as thev did in the loaf width series.
