Stimulation of Pollen Tube Growth in Vitro by Thiouracil and Other Antimetabolites of Nucleic Acid Bases
Acta botanica neerlandica , Volume 14 - Issue 1 p. 148- 154
25 Purines and pyrimidines were tested for the effect on pollen tube growth and germination. 2-Thiouracil most strongly stimulates tube growth. However, 2-thiouracil decreases or does not affect metabolism of sugars. Some derivatives of thiouracil also stimulate tube growth, whereas others inhibit growth. Pollen growth response is markedly affected by the concentration of the compound tested.
