Abstract
IT has been claimed that polyvinyl alcohol (PVA) enhances both the growth and chlorophyll concentration of certain green algae and pea plants1–3. This effect of PVA on green algae has recently been questioned by Zuri and Mayer4, who were unable to confirm the earlier work. It is therefore appropriate to report briefly on some hitherto unpublished work relating to the effect of PVA on pea plants, which was carried out in this Laboratory shortly after the paper by Rejniak et al.2 was published.
