Fig. 2. Relationship between micronaire and time of defoliation based on various open boll percentage at defoliation (OBPD) for each gap type over 3 yr at Clayton, NC. Each data point represents micronaire values from at a particular OBPD measured in an individual plot at harvest. * Slope of the gap and no gap treatments for that year are significantly different from each other.
