The Blooming of Wheat Flowers 
23 7 
Considering the head as a whole, the flowers above the first flower to 
bloom completed their blooming before those situated below this flower. 
From 8 to 60 per cent of the flowers below remained unopened at the 
time those above had finished blooming. 
The lowest flower in the spikelet usually blooms first, and the other 
flowers of the spikelet bloom in order from lowest to highest on succes¬ 
sive days. 4 few exceptions were found, however, where flowers failed 
to behave in this manner (see fig. i, head 4A, spikelets 11, 12, 13, and 
17). A number of instances were found where two flowers in the same 
spikelet bloomed on the same day. Complete data on these flowers is 
shown in Table V. In all, 39 such instances were recorded. The aver¬ 
age time which elapsed between the blooming of the two flowers in the 
spikelet was nine hours and four minutes.
