Temperature Relations f oi' the Entire Culture 

 Period ( About 110 Hours) . • 



Table IV presents the series, type, and 

 temperature averages for the entire culture period, being 

 a svimnai^jr of the temperatvire relations shown by the 42 

 tables, of which Table I is a sample and f rom wh Ich tables 

 II and III v/ere derived* In each case the minimum and 

 maximum are given, es well as the average, the tiiree 

 values (in hundredths millimeter per hour of shoot growth, 

 for periods ranging from 108 to 114 hours) being given 

 consecutively, separated by colons, in the serial order: 

 minimum , a v e r ag; e , ma x imum » For example, referring to 

 table I, the average for all solutions of- the first test 

 is .64 mm., the mlnlm.um is .53 mm., and the maximxHti is 

 .71 mm. Hence, the summary of the first part of table I 

 may be represented by the formula 53:64:71. In like 

 manner, the summary for the second part of table I is 

 63:70:77. The averages fcr the several pairs of like 

 tests (excepting for the lov/est temperatiJire , for vfhich only 

 One testwas made) are shown in the next to the lest coliimn 

 of table IV and the grand average for each temperatvire 

 is given in the last col wan. The grand averages bring 

 out very clearly the facts that the highest rates of shoot 

 elongation were obtained with the maj.ntained temperatures 

 28 and 31 (tlie values being about alike), that temperatures
