✦ Synopsis

A rather precise combination of the three phytohormones, gibberellic acid, auxin, and abscisic acid, is necessary for the considerable growth of fiber nucleoli in Gossypium hirsutum L. for about 8 days after anthesis and for nucleolar "vacuolation" in the second half of that period. Nucleolar growth and vacuolation must occur in a precise sequence for the fiber to reach a good final length. Nucleolar vacuolation indicates simultaneous output and neosynthesis of nucleolar material.

## Abstract The crystallite reorientation brought about by the swelling of cotton with sodium hydroxide solution (NaOH) has been investigated. The degree of reorientation as indicated by the decreased value of x‐ray angle may arise from deconvoluting and not necessarily from a change in orientation

Although the ability of hormones and growth factors to stimulate DNA synthesis in rat hepatocytes has been investigated extensively, no such study of human hepatocytes has been reported. Here we describe a series of experiments to identify those factors that regulate human hepatocyte DNA synthesis i
