โœฆ Synopsis

A number of components isolated from styles of P. avium cv. Napoleon ($3S4) have been tested for their capacity to influence in vitro growth of pollen tubes from fresh and stored pollen (cv. Napoleon ($3S4)). An antigenic glycoprotein (Antigen S) is a potent inhibitor of in-vitro pollen tube growth, causing a 65% reduction in tube length at a concentration of 20 gg/ml. None of the other style components were effective inhibitors of pollen tube growth; neither were proteins of animal origin such as histone, serum albumin, cytochrome C, and the glycoproteins ovalbumin and thyroglobulin, effective inhibitors.

The effects of canavanine, ~,y-diaminobutyrie acid, homoarginine and lathyrine on the germination of pollen and on in-vitro growth of pollen tubes were studied in the following species: Lathyrus niger, L. 8ilvestris, Vieia uni]nga, Pisum sativum and Citer arietinum. The effects of these non-protein
