Abstract
It was found that during the germination of Arachis hypogaea L. (peanut) seed the RNA content increased to a maximum (2-fold) during the first part of germination (2–6 days) and subsequently decreased with further germination. This is contrary to previous reports on the depletion of RNA from the storage tissues of corn, bean, and rice seeds. The pattern of RNA metabolism was quite similar for four varieties of mature and immature peanut seed and between the same variety produced in two different locations. The minor differences between varieties might possibly be related to seed size. Reinvestigation of nucleic acid changes in the corn scutellum showed that the RNA content increased 20% the first day of germination, but decreased thereafter. In most cases, the DNA content of peanut cotyledons and corn scutella did not change significantly during germination.
