Physical State of Cellulose During Ripening of Peach

SUMMARY Cell walls of ripening fruits of peach were purified of a large part of their non‐cellulosic components and examined with X‐ray techniques. Small, but distinct, increases in micellar size, and perhaps in percentages of crystallinity, are a function of the maturation process. These increases are interpreted as evidence of a limited degradation of cellulose (broadly defined).
