Influence of some free amino acids of the ovule on growth and cellular development of the pollen tube of Juniperus communis L. in vitro . The extraction and analysis of free amino acids show that a partial complementary relationship exists between the amino acids of the pollen and those of the ovule of Juniperus communis . The main free amino acids of the pollen are threonine, proline, arginine and γ‐aminobutyric acid; those of the ovule are threonine, serine, alanine, citrulline and glycine. The addition of the main amino acids of the ovule in the pollen culture media increased the growth and the cell development of pollen tubes cultured in vitro . This indicates the nature of the correlations which exist between the male and female gametophyte of Juniperus communis .
