These kernels would not fill later, even if stress was relieved. The 14 Fill-ins include two volumizing wefts meant to add volume and fullness to short hair styles. It was speculated that a stress applied in the first 1 to 2 weeks after pollination caused a temporary shortage of assimilate for the ear, severely limiting endosperm cell number of some tip kernels. Duration of the sensitive period varied from 6 to 23 days. The growth stage when shading decreased the final kernel number was closely associated with early kernel development, occurring near the end of the lag period of grain filling. The number of kernels of each treated plant was measured and treatment means were compared with unshaded controls.

In order to define when number of kernels was affected, the panels were moved three times each week to provide an overlapping series of treatments. 3312 (Elk Grove Village office), 847.885.4100 (Hoffman Estates office), 847.842.0180 (Barrington office) and 847.577.1023 (Elgin office). Number Fill-In 5. Plants were stressed using horizontal shade panels that reduced the light by 79% for approximately 13-day intervals. Three commercial maize hybrids were grown on a Houston black clay (fine montmorillonitic, thermic Udic Pellustert) under irrigation near Temple, TX in 19. Directions: Fill in the correct number or word(s). The objective of this experiment was to determine the growth stage when shading stress affected number of kernels per ear. Knowledge of this interval is important for understanding yield potential, modeling, irrigation scheduling, and the study of the partitioning of assimilate into grain. There have been many investigations into the time interval when maize ( Zea maysL.) yield is most susceptible to stress.
